---------------------------------------------------------------------- Date: Mon, 29 Dec 1997 15:38:03 -0000 From: Jim Liddil <jliddil at azcc.arizona.edu> Subject: cleaning, sanitation, clinitest, plastics The clinitest discussion is an interesting one. But I think some basic things have been lost in the general discussion. A hydrometer and the clinitest are tools that can be sued to evaluate the state of your beer. Along with these tools we can also use our experience and our senses. A hydrometer should be calibrated once in a while since I know more than one person who has had what he thought were problems with fermentation. Also the clinitest should ideally have a set of positive and negative controls included in the kit, even if it is an FDA approved test kit. We can use our sense of taste to figure out if a beer is fermenting correctly. I do this when I use my hydrometer along with a glucose test kit. All these methods provide data. the more data the better. Plastics, cleaning and sanitation have come up lately. First WRT glass anyone who has worked in a lab with proteins knows how tenaciously they bind to glass. As a datapoint our lab media bottles are cleaned in a dishwasher which has a spray jet the each bottle is placed on to. After the dishwashing cycle they are then autoclaved, so they are sterile. Being an Anal Chemist at heart I still have our students treat all the bottles once or twice a year with chromic acid solution ( mixture of potassium chromate and sulfuric acid). Every time we find at least a few bottles the still turn the acid from orange to green indicating organic matter is in the bottle. this is for bottles that are right from the dishwasher. I have to constantly remind our students that things have to be clean before autoclaving. The are not the same. After all I can autoclave feces and then it is sterile. All the discussion of sanitation has failed to address the issue of making sure the surface is really clean before any sanitation is to occur. And with the high organic load of brewing you really have to use some strong cleaners to get the grunge off. We also have to deal with things like calcium deposits of one sort or another that can also trap dirt or provide hiding places for microorganisms. Jeff Renner told us about his pump woes. I don't use such a pump but as I recall these pumps have the outlet restricted. It's no wonder there is all kinds of gunk inside these things. Beer wort even when it is clear is loaded with suspended solids. CIP is for big guys who need to make money and don't have time or can't be convinced take things apart and clean them. My advice is to take it apart each time. Or you can use PBW or whatever and then follow that with an acid rinse to dissolve all the Ca and Mg salts. George DePiro mentioned the article by John Palmer and myself. I wrote all the info on sanitation and thus feel qualified to comment :-) The concentrations and times I presented are either from "Disinfection , Sterilization and Preservation" or from discussions with people at Clorox and a couple of companies that make sanitizers and disinfectants as well as the guy who actually developed current iodophor formulations. These data are based on AOAC testing, which is the organization that covers all testing methodology for these agents. In order for an agent to be registered with the FDA, USDA etc. it must pass the given test. Products like One-Step (TM) can not be labeled as sanitizers because they are not registered with the US Gov't as such. From our article: >The most common terms used by homebrewers are sanitize and sanitizer. In general. >sanitize means to use an agent to reduce theca number of microorganisms to safe levels. >One official definition states that a sanitizer must kill 99.999 percent of the specific test >microorganism in 30 seconds (2). It is generally acknowledged that 90 percent of the >sanitizing process is the physical cleaning of surfaces and the other 10 percent involves the >use of a sanitizing agent (3). The focus of this article will be interpreting these definitions as >they pertain to homebrewing. >To simplify matters we will talk primarily about cleaning and sanitizing agents. how to use >them and how they can affect our brewing equipment. Some of the chemical agents >mentioned may also be disinfectants but we will refer to all of them as sanitizers to avoid >confusion. >All sanitizers mentioned in this article are meant to be used on clean surfaces. Their ability to >kill microorganisms is reduced by the presence of dirt, grime or organic material present on >the surface being sanitized. These organic deposits can harbor bacteria and shield the >equipment from being reached by the sanitizer. So it is up to you to make sure the surface >of the item to be sanitized is as clean as possible. This may require a certain amount of >scrubbing, brushing and elbow grease. but remember that a dirty surface can never be a >sanitized one. WRT to bleach I have corresponded with Dave Burley and I'm sure he will provide more data on what is in a bleach solution. For instructions on how to use bleach to sanitize, disinfect and clean check out the clorox site (www.clorox.com). Again sanitize and disinfect are essentially legal terminology. I favor using strong cleaning agents like 10% bleach (the current CDC recommended conc. for blood disinfection), or any number of other cleaners (PBW, autodishwasher detergent, alconox etc.) I also usually acid rinse all the equipment. BTW I brew in nothing but plastic. I am doing a little test of plastic and how well it can be disinfected etc. I'll provide data (limited as it may be) in a few more days.

I know that I should just take the plunge to all grain, but the time and $$ for equipment just ain't there. Private email is fine, I'll post if there's any interest. Now that Jeff Renner has been established as the Northern Brewing Pole, we need a Southern Pole so we can get started on the HomeBrewers Globe. :> TIA John Watts watts at top.net Return to table of contents
Date: Mon, 29 Dec 1997 18:26:37 -0800 From: BBrowne at golder.com (Barry Browne) Subject: Lactose as sweetener?; W2308 habits Brewlings, I recently brewed one of my standard beers, a specialty with rye, using a different mashing schedule to lower the FG to better balance the beer (it was a bit too sweet). Well it worked and I got an FG of 1.012 rather than the usual 1.017. It now seems that I overdid the 60C rest and wish this beer had just a bit more residual sweetness. Now I'm thinking about a way to add a bit of sweetness to this kegged beer without causing additional fermentation. Artificial sweeteners are a choice but not one I'm willing to select. So my brewing mind wends it's way to lactose, the unfermentable but not so sweet sugar that has purportedly been used historically in sweet (milk) stouts. What I'm asking of the collective is comments on this application for lactose and a recommended dosage rate. I would be adding it to corny kegs so it will be easy to do. I brewed only the second lager of my career, a doppelbock, which is fermenting apparently happily at 50F with W2308 Munich lager yeast. Wow talk about H2S!!! Anyway, this yeast has a rep for being "moody" so I'm trying to do things just right to minimize the chance of having this yeast get pissed off at me and play tricks on my doppelbock, an all-grain OG 1.082 beauty. The references I've read indicate that this yeast should be kept at 50F for about a week before being racked to secondaries, then the temp should be lowered to 35F for an 8 week lagering period. Books and magazines are great but the HBD is better for advice. The questions pertaining to W2308 are: 1. What apparent attenuation (or fraction of expected final AA) should I look for before dropping the temp to lager? 2. Any ideal lager temp. 0C, 1C, 2C, etc? 3. When during the process should I conduct the diacetyl rest and what strategy is recommended? 4. The primary ferment has shown a pretty sizable krausen, will this "drop" into the beer at the onset of secondary ferment as would a S. cerevisiae strain? 5. Any other advice that a seasoned ale brewer could use when brewing a lager. Many thanks for your advice. Barry Browne Atlanta, GA Return to table of contents
Date: Mon, 29 Dec 1997 12:08:13 -0500 From: Chris Dodge <cdodge at ptc.com> Subject: Hops Direct If any of you are looking to buy hops you may want to take a look at a new distributer, Hops Direct www.hopsdirect.com. They are a hops farm in Washington state that has now setup a way homebrewers can order directly from them. The prices are very very good. They were very helpful and accomidating when I placed my order. Check out thier web page or call and ask for Dianna, (509) 837-3616, she was very helpful. They are also listed as a supplier in Washington in the Brewerys http://realbeer.com/brewery/infobase/supplierlist/SupplierList.html supplier list under Puterbaugh Farms Hops Direct. Sorry if this seems like an add, but I was very impressed with them and thought I would let everyone in on what seems to be a great way to get the freshest hops. Chris Return to table of contents
Date: Tue, 30 Dec 1997 13:18:22 +1100 From: Meliora & Drake <meliora at macquarie.matra.com.au> Subject: Lactobacillus Infection and Printed Caps Hi all, I have a Weizenbier that has developed some odd symptoms while settling: 1) A slight cloudy appearance 2) A faint white scum on the surface of the brew, more pronounced where there are bubbles on the surface. 3) A slight musty smell, a bitter/sour taste reminicent of Brussel Sprouts. Is this a lactobacillus infection, some other infection or something else? Also, are there any companies that will make up Crown Caps with your own design printed on top and kinds of price / quantity are we looking at? Cheers, Drake Morgan, Australia.

Date: Mon, 29 Dec 97 12:37 PST From: cburns at egusd.k12.ca.us (Charles Burns) Subject: Barrel o' Dunkel - Part 2 While the decoct was boiling we heated up about 30 gallons of sparge water. Nobody paid any attention to the temperature. We boiled it in 3 kettles (removing city water chlorine) and let it cool a bit before the sparge started. Estimated temperature was about 190F (my opinion). Getting the sparge water into the 15 gallon sparge water vessel was interesting. It was perched on top of another plastic milk carton, looking a lot like the tower of Pisa (leaning a bit). We (actually them, I've got a back that prevents this type of activity thank goodness) poured about 4 gallons at a time from the 15 gallon kettles into an 8 gallon pot that was raised overhead as far as we could reach and then dumped into the sparge water vessel. Right, you could not see the water level in the hot liqour tank without jumping. You had to be there... This is when we discovered Dave's assurance about not needing to stir the decoction wasn't quite accurate. We had about an 8 inch circle of very black and very crusty carbon stuck on the bottom of the decoct kette. Ended up using some fairly coarse grit sandpaper and a ton of elbow grease to to remove it. After recirculating about 4 gallons the wort began to run clear. And then it nearly stopped. Uh oh. 70 lbs of grain and a stuck sparge. Never fear says Dave the Dangerous brewer. He sticks that nozzle from the hot water tank into the output hoze from the mash tun and blasts hot water in under the mash in an attempt to float the grains. Several times. Eventually we disconnected the valve from the runoff hose (it was sucking air) and got the sparge to at least trickle off. Took about 2+ hours to complete the sparge. Good thing too, because we were all hungry and needed some food and time to eat it. Ended up with take out mexican tacos, burritos and some other stuff I cannot pronounce, but all really delicious. We ran the wort off into 3 kettles, about 12 gallons in each with about 3 gallons left over in spare pot. One of the kettles was quite a bit lower in sugar than the other two. Our plan was to put a "T" in the sparge runoff but it was so slow we just tried moving the runoff hose from kettle to kettle. It was a beautifully clear, deep ruby red wort by the time we finally finished the sparge. My kettle was the light one and as it boiled down, we fed it from the left overs. 3 different kettle shapes and 3 different types of burners. The kettle I was working boiled long before the others, even though I think the BTU rating on that burner was lower. Interesting data point, my kettle was wider than the others (different style keg). We hopped the 3 kettles pretty much the same. Boiled for 15-20 minutes, added 80 grams of Spalter (4.6%AA) for a 60-70 minute boil. Dave uses only whole hops, the rest of us used pellets. The dangerous brewer brought out his pre-chiller, ice and a hammer and start wanging away with ice chips flying all over the place. I had a chiller with me so we chilled each kettle with two chillers and got them all down to pitching temp in about 20 minutes each. As we cleaned the mashtun we found that most of the dark grains had all collected in a pocket at the edge of the mashtun. Thus the reason we have a ruby-red dunkel instead of a dark brown one. Its a pretty wort, just a bit out of style for color. Somebody remarked "you can't taste color, who cares". And the wort did taste wonderful. Every kettle ended up right around 1.060 OG - a fairly big Dunkel. I pitched about 12 ounces of Munich Wyeast 2308, in a glass 6.5 gallon carboy, the others used 2 each 15 gallon stainless kegs and one 15 gallon open fermenter. All added up we had about 33 gallons of finished wort. Dave and Brian's used 34/70 which I think Dave said was the same as Wyeast 2278 - Czech Pils yeast. Mine is at 54F today, Brian's at 45F and I think Dave said he'd leave his out on the patio for awhile - anywhere from 34F to 56F lately around here. Man was that fun. We finished up around 6:30 pm (about 2 hours later than we had expected), all of us tired and ready for another beer. I want to thank Dave for a great opportunity to participate in this landmark homebrewing event. What a blast it was and a great way to spend a holiday weekend. Give us a couple of months and we'll be taste comparing to see which yeast/ferment conditions did the best. Grist for 1 barrel of Dave's Dunkel: 22.5 kg DWC Munich, about 8L 7 kg Crisp Lager malt, about 1.8L .5 kg lb 100L Crystal .4 kg Special B, about 150L .2 kg Black Patent 240 gm Spalter at 4.6 AA for 60-70 minutes.

Date: Mon, 29 Dec 1997 18:15:35 -0800 From: Jack Schmidling <arf at mc.net> Subject: Corn, Roller Spacing, Breakthrough From: Jeff Renner <nerenner at umich.edu> Subject: Organic corn meal and flakes cost "But make sure it's degermed, not whole corn meal. The organic stuff we get here is whole meal, which makes great corn muffins, but contains far too much oil for brewing (although Jack Schmidling uses whole cracked corn without complaining). Thanks for pointing out my variance from the dogma but I would be curious to know where this one comes from. Commercial brewers use corn by the train load and I would be very surprised if they degerm it. "" Why is flaked maize so damn expensive to homebrewers, anyway? It "" costs more than imported Pilsner and Munich malt! "A data point - the wholesale price for 25 lb. bags of Briess flaked maize just dropped nearly 50% here... You forgot to tell us where that leaves us but I suspect it is a long way from the $10 or less for a 50 lb bag of whole corn and also did not answer the question. The reason it is so expensive is because people are willing to pay the price and it is a lazy man's product which is always assumed to cost more than doing things the hard way. From: Kyle Druey <kdldmd at lightspeed.net> Subject: How to Use Gap Spacing / MM Pricing Strategy "I can recommend what works for me when doing a RIMS mash.... Say no more. Next.... But while on the subject, this just seems to me like another strike against RIMS.... in my opinion.. an overly complicated and expensive way to do something that is otherwise rather simple and easy. " Looks like the MM and the VM both have similar variable gap spacing tolerances built into their production.... Nothing on earth can be made without tolerance but I don't understand the significance of the statement with regard to an adjustable mill. The home position is set and calibrated to be the same spacing (within the tolerance) as the fixed mill. What you do when you change the spacing, the manufacturer can not be responsible for. The tolerance BTW, is on the order of .005". So they are all the same within that limit and no hombrewer could possibly detect any difference in the crush of the same malt in mills within that tolerance. The problem I pointed out was that not even god knows what the spacing is because he did not tell us how deal with the peaks and valleys when measuring it. "Now I find out that if JS (can't remember which HBD he recently posted this) wants to he could sell direct and undercut Listerman (this would be less than $75). Why don't you do this (duh, fat profit margins)?.... You seem to have missed the point. That happens to be about the wholesale price, i.e what the retailers pay for them. If I sold them directly for that price, no dealer would talk to me and you would not find them sitting on their shelves all over the world. A very comforting feeling, no matter whom you by it from. "More of us would then purchase your product..... Actually, far fewer of youse would purchase them because you would not find them in your neighborhood store. Besides, if everyone bought one, we would have nothing to argue about and the Digest would be far less interesting as a result. " Just think, I could have been a MM owner right now if you had adopted this pricing stategy.... Not unless you happened to stumble into my web page or had seen my tiny little ad in the magazines. As I said, 99% of our business is through retailers. When I decide to "retire" again and wind it down, I might just take your advice. " and you could be getting all this free advertising in the HBD.

This is known as "breakthrough" = Oh boy! Another buzzword! "Being less soluble in the beer, unable to pass through the bubble wall and therefore trapped in the foam bubble, the nitrogen does support the foam for a lot longer than if the foam were pure CO2. Well, all I can say is this is why I still read the HBD. This is either heigher tech than I can handle or I got sucked into a joke. Are you talking about beer or Charlie on the MTA.

Date: Tue, 30 Dec 1997 00:30:53 -0500 From: Spencer W Thomas <spencer at engin.umich.edu> Subject: Re: Exploding Bottles Pat, I agree with everything you say, but there is something you didn't say. If an underfilled bottle bursts, it is more dangerous than an overfilled bottle bursting, because there is a larger volume of compressed gas to drive those shards of glass away from the center of expansion. If you've got 10ml of gas at 5atm and your bottle fails, the gas expands to 50ml ("clunk"). If you've got 100ml of gas at 5atm and the bottle fails, the gas expands to 500ml ("bang"). And if there's no gas, the bottle will quietly break with almost no dispersion of fragments. This is why gas cylinders are hydro-tested instead of testing them with pressurized gas. In the first case, you get a split cylinder with some water running out (assuming an efficient check valve in the test equipment). In the second case, you get a really nasty bomb or torpedo. But you knew that. =Spencer Return to table of contents
Date: Mon, 29 Dec 1997 21:40:43 -0800 From: Kyle Druey <kdldmd at lightspeed.net> Subject: RIMS Element Removal for Cleaning If you don't care about RIMS then you might want to page down now. In a recent post Jeff Renner explains the need to clean his pump. I think this is advice that should be headed, and is also applicable to a RIMS heating element. There was a thread on this about a year or so ago, but I blew it off, thinking that these beer geeks were being just too anal retentive. Was I ever wrong! I am now a converted anal retentive beer geek now using the 63rd edition of the CRC Handbook. Several months ago a foul stench began to fill the area in my house where I store my brewing equipment (corresponded with peak 110 F summer time temps here in the great San Joaquin Valley). I finally traced the odor to my RIMS heating chamber, removed the element, and was appalled at the black and green fuzzy growth on about 1/4 of the element sheath. From that time on, I removed my heating element after every batch and cleaned it. There is always some kind of tan spongy crap to clean off after the brew session. I know some of you report that the element is always clean and you never have problems, I hope this continues for you, if you're not so sure then read on. The main point of this post is how to incorporate in your system design an easy way to disassemble your RIMS heating element so that it can be cleaned after every brew session. Off the shelf RIMS equipment may not have this as a design feature. To investigate a solution to this mind boggling matter I consulted the RIMS doctor, Mr. Dion Hollenbeck. As expected, Dion was ever gracious and had the answer, and with his usual elaborate detail. With his permission I post his response to me from our private email correspondence: - ------------------------------------------------------------------------- RIMS heater element bushing selection. To get the correct fit of a RIMS heater element into a threaded bushing (or any other pipe thread), you need some knowledge of the threads and you need to pick the threaded part carefully. Armed with this knowledge, the task is simple. In my estiamation, anyone who does not remove their RIMS heater element after every brew is asking for trouble. Unless you use CIP (Clean In Place) procedures with highly corrosive chemicals, the element needs to be removed and cleaned with a soft bristle brush and hot water to remove the layer of biege goop that collects on it from the grain. If this is allowed to remain, you risk the chance that it will rot and spoil your next batch. This is not idle theory, but in fact happened to me before I realized the necessity of disassembly, cleaning and thorough drying after every batch. Regarding pipe threads, there are two pieces of information necessary. A standard 1.5" x 1" reducing bushing has internal threads of 1" by 11tpi. These threads are NPT (National Pipe Taper) and as the name implies, are tapered. All manufacturing processes have tolerances, and during its manufacture, the bushing may have landed on one end or other of the tolerance limits. Water heater elements utilize 1" x 11tpi NPS (National Pipe Straight) threads. Tapered threads produce their sealing action when the tapered male thread is forced into the tapered female thread and the harder they are screwed together, the tighter the threads mesh. Straight threads have no self sealing action and are generally provided with a rubber gasket to accomplish liquid sealing properties. In all other respects, the straight and the tapered threads are compatible. When you attempt to mate the heater element with straight threads into the pipe fitting with tapered threads, it is important to hand select a fitting which will allow a seal to be created. If the fitting is on the low end of the manufacturer's tolerances, in other words, the tap which created the threads was not driven in fully, chances are very good that the straight threads of the heater will bind in the tapered threads of the fitting before the rubber gasket makes a liquid tight seal. What you need to do when you buy the bushing into which the heater screws is to take the heater with you. Try every bushing they have until you find one that will allow you to screw the heater into it BY HAND until the rubber gasket on the heater comes in contact with the bushing face. With this kind of fit, you can hand tighten the heater, then use a wrench to apply one more quarter turn, providing a liquid tight seal without any kind of teflon tape, pipe dope, or cranking down hard on the threads. In this manner, you can easily remove the element after every brew for cleaning. It only takes me about 30 seconds to completely dismantle my pump from the heater chamber, remove the two temperature probes and the heater element. ________________________________________________________________________ As with all his stuff, I was very impressed with his treatise on bushing selection and thought the collective would benefit from it. Of course, I did not head his advice and had to come up with a more expensive solution 8>). I purchased a 1" brass quick disconnect fitting. The male end was attached to the element and the female end was attached to the heating chamber. All I have to do is just plug/unplug the element for use or removal. The brass QD fittings get very hot at the end of the mash when you want to remove them. Wrap a few turns of electrical tape around them so that they can be gripped for removal. One disadvantage to my approach is that it adds about 2" extra dead space at the end of the heating chamber. I had to drill and tap a small port near the highest point on the male 1" QD fitting, insert a screw, and turn it out to relieve the trapped air.

Since I live in Florida where our wonderful laws do not allow the sale of beer in metric measurements (thank you AB lobbyists) or even ordering beer from out of state, it's a great opportunity to obtain some tasty Belgian ales. Any tips on procuring and shipping from any good bottle shops in and around Brussels would be greatly appreciated. Return to table of contents

"I have a friend who (I am begging forgiveness even before I mention the name of the beer) likes Coors Light.... My mother would wash our mouths out with a bar of soap for saying things like that. "I know the Grist Bill calls for corn and rice, but don't know the percentage they represent, nor the hopping profile, O.G. or if it is 6 Row or 2 Row? Any specialty malts? Just about any combination of stuff will work but real corn would be overdoing it. They use corn syrup and Caro is a good option. You don't need to bother with the malt if you use enough of it. The most important ingredient that seperates Coors (and all the rest) is water, as in Rocky Mountain Spring water. Use lots of it, just before bottling. Remember, after you have made the sleaziest beer you can, you end up with what they call "beer concentrate" to which you must add ample quantities of water, then force carbonate.

Neitzke" <neitzkea at frc.com> Subject: Old barrel reconditioning A buddy of mine has inherited several old wisky barrels from his grandfarther. His grandfather used thes barrels to ferment wine. Unfortunatly the barrels were not well cared for, before he recieved them, a couple of them are slightly rotted and are no longer useful, however some of them look pretty good but have mold growing in and around the bung holes. Does any body have a suggestion on how to clean these barrels, to put them back into service? Private e-mail please, since this isn't strictly beer related, thanks. _________________________________________________________ Arnold J.

I was planning on using almost 100% munich malt (maybe a little aromatic and caravienne as well), as I have read good things about it as a base malt for this style. However, I have also heard that using more than 25 - 50% munich can lead to "flavor problems", although just what these might be was not elaborated. Anybody have any ideas? Also, I wondered if anyone had any opinions about the difference between DWC and Weyermann munich malts. Any input would be appreciated, Mark Tomusiak Boulder, Colorado Return to table of contents
Date: Tue, 30 Dec 1997 15:54:23 -0600 From: lheavner at tcmail.frco.com (Lou Heavner) Subject: death by bleach.... Trying to make sense of the discussions on sodium hypochlorite solutions. Yes I once worked in a process that used both hypochlorous acid (HOCl) and sodium Hypochlorite (NaOCl) as reagents. We produced our own by bubbling Cl2 gas in water (closed system so Cl2 fumes were not a problem, but excess Cl2 was controlled) and later reacting with caustic soda (NaOH at about 12% as I recall). Chlorine will react with water to produce HCl and HOCl. Addition of NaOH will neutralize the HCl producing NaCl (table salt). Additional NaOH will react with the HOCl to yield NaOCl. I think the pH for a solution with essentially no HCl or NaOCL is about 5 or 5.5. Below that, you have HCl and possibly free chlorine gas. As more caustic is added, pH risesand HCl then HOCl disappear. I think that most bleach (and many drain cleaners like liquid plummer) contain about 6% excess NaOH. Everybody essentially reacts Cl2 with 12% caustic until there is 6% excess caustic remaining. So the first point is save your money and buy the generic bleach. There really isn't any difference, especially after diluting it. <speculation mode on> I believe that the excess caustic is what does most of the cleaning and that the -OCl is what does the sanitizing. We were told that HOCl was pretty unstable and kept chilled. That may have also been related to Cl2 solubility in water. Eventually the OCl will break down presumably in the act of sanitizing so that you end up with more NaCl. NaOCl is more stable than HOCl, but HOCl doesn't exist in common bleach with excess caustic. Available Chlorine or AVCL is used to measure how much OCl is present. Oxidation-Reduction Potential (ORP) can be used in concert with pH to infer AVCL. I have always been told and believed that bleach was deactivated more quickly at higher temperatures. What are the mechanisms? I don't know. Does this simply mean that sanitizing is occuring more quickly? I don't know. Is this just another momily? I don't know. <speculation mode off> I don't sweat it much. I use excess bleach. It's cheap and within reason, more is better. I'm careful. I don't want to ruin my clothes, and I want to be able to see if I do!! I clean everything as best I can before using bleach to sanitize. I rinse anything that cannot drip dry with water. I have never had problems rinsing with tapwater, but if I did, I would switch to boiled water. BTW Dave Burley, I was in Sam's over the holidays and saw the giant size Quaker 1 minute oats. I checked the ingredients and it said 100% rolled oats. No mention of papain or anything else. The papain would have been a good explanation for the heading problems I had with my oatmeal stout. But according to the label, it's not there. Any other ideas?

An uncle who died slowly of sclerosis of the liver, swollen belly and all, the father of my godchild who ruine= d lots of lives with his affliction, the best secretary one could ever hope= = to have, suffered divorce and loss of her family and died a lonely = alcohol-soaked woman and an engineering manager who was the smartest, most talented guy who ever worked for me died at an early age, unhappy for most of his later life because of the ravages = of excess alcohol consumption. I know what alcoholism can do and I know how easy it is for an alcoholic to fool himself into thinking he's OK - I've seen it up close and personal. One little trigger can send him off on a bender that may destroy his life and worse - others' lives. Anecdotal evidence = such as your personal experience is not proof of anything as it relates to other people. = As a result of these personally painful experiences, Jack, I have no patience for your kind of diatribe in this area, since the belief that you or others can easily and reliably produce alcohol-free beer from alcohol-containing beer or that alcoholics can drink one beer a day is absolute crap and there is lots of scientific evidence to prove it - deny it if you will- that does not = change the truth. If any readers out there believe Jack, hang around an alcoholic for a while and you'll find out what absolute bullshit Jack's "beer-a-day" contention is. - ----------------------------------------------------- Mike Rose of my old Alma Mater, UC Riverside, says: >I saw a recipe on the web(cats meow maybe?) that gave a basic stout >recipe and then called for the addition of 40cc of lactic acid before >bottling. Would this provide that Guiness *tanginess* or is this just >throwing the ph of the beer way off. 40cc of 88% lactic acid in 5 gallons would be undrinkable IMHO. Maybe 2-4cc is more like it. In any event, try a small sample to arrive at a tanginess that is suitable to you. In later batches I would put it in earlier than the bottling step, perhaps the cold wort before fermentation, so that you don't have a problem with protein precipitation, color loss or whatever in the bottle from the lower pH . See the next topic below. = - ---------------------------------------------------------- Mark talks about using the "chef levain" method of capturing wild yeast by leaving the flour sponge exposed to the air to make sourdough. = Try this experiment. Make a sponge, leave half of it covered and the other uncovered. You will get leavening in both because the majority of yeast is in the unbleached flour and = doesn't come from the air. I don't know about bleached flour, but suspect the same. Ground and uncooked malt in a wort will produce a lactic culture of sour beer (Boil it before using it to add to your beer), used to make stout wort acidic. See the archives. I have used this in making sourdough bread. As I recall, about 3% of this stale beer is added to stout. My past experiments have shown this sour beer fermentation to produce 0.1N lactic acid overnight. 3% of 128 ounces is about 4 ounces. And 0.1 N lactic acid (MW 60) is 6g/liter or about 6 ppt. 4 ounces of this sour beer would contain 0.024 ounces of lactic acid or 0.027 ounces as 88% lactic acid. . If a tsp is 5 mls then this amount is about 0.4mls per gallon of beer or two mls or half a = teaspoon of food grade 88% lactic acid per 5 gallon batch. = As you may know, beer yeast was used to leaven bread for centuries before special baking strains were developed. - ---------------------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3202 at compuserve.com Dave_Burley at compuserve.com = Voice e-mail OK = Return to table of contents
Date: Tue, 30 Dec 1997 21:29:11 EST From: SCRIT <SCRIT at aol.com> Subject: RIMS and such I have 3 tier system and was planning to use a pump for recirculation of the wort during mashing. My mash screen is the unit sold by Heartland homebrew supply so the amount and clearance underneath the mash screen is minimal. What would be the risk of scorching if to increase tempuratre during a stepped infusion mash I were apply heat to the bottom of the mashtun and pump to the top of the mashtun, ala RIMS. I was thinking that I either would compact the grain bed so bad that sparging would be impossible or I would scorch 25 pounds of some really nice Pilsner malt. I was also going to use the pump to recirc the wort post boil to filter and to push the wort thru the chiller. Any comments on that plan are welcomed. Thanks,, Joe Return to table of contents
