How about some thoughts from you mash hoppers" ... snip "3 oz. EKG in mash" One thing to note, as it is important I think, use only pelletized hops. If you used whole hops they are not going to release much in the way of oils just sitting in a mash. They need the action of a boil. Pellets, however, just dissolve. For general info on mash hopping see our hop usage page: http://www.paddockwood.com/guide_hop_usage.html ______________________________________________ Paddock Wood Brewing Supplies, Saskatoon, SK orders at paddockwood.com www.paddockwood.com Return to table of contents
Date: Mon, 25 Sep 2000 18:43:07 -0400 From: Michael Marshburn <mike48 at rcn.com> Subject: Temp Controller Just a quick question or two to the collective: Anyone familiar with the Tek Supply Waterproof Prewired Thermostat and if it could be put to use controlling the temp on a refridgerator? It looks like it would have to hang inside if the coil at the bottom is the temp sensor. Another question on FWH: I made a pilsner earlier in the year and used the procedure and was really pleased with the results. Its still warm here in VA, but I'm out of HB and I have a couple of cans of liquid malt I won at the HB club meeting. Would it produce the same results to keep the wort at around 170F for about an hour with the flavor hops added then boiled as usual with the bittering hops?

Date: Tue, 26 Sep 2000 10:56:19 EST From: "Warren White" <warrenlw63 at hotmail.com> Subject: Will the real Boddingtons please stand up! Close but no Cigar Brad McMahon Time to turn to (who I consider to be) the clone masters, Wheeler & Protz. According to the latest edition of _Brew Your Own British Real Ale_, Boddingtons Bitter is OG 1035, 7 SRM, 3.7% abv & 37 EBU. The recipe Wheeler gives is 92% pale malt, 5% crystal, 3% sugar. Hops are Whitbread Goldings for the boil and a 2:1 ratio of Kent Goldings to Fuggles in the finish - for US 5 Gal 0.3oz Kent Goldings 0.15 Fuggles. The reason why the beer tastes less bitter and has little hop aroma is probably largely because it is served via nitrogen dispense rather than by a gravity hand pump. Here's to beers, Brad Aldgate, Sth Australia * * * * * * * * * * * * * * * * * * * * * * * * * * * Boddingtons like a lot of other U.K. nitrocans we find on our Bottle-Shop shelves (Tetley, Double Diamond etc.) *DOES* does come in a Cask-Conditioned entity... The Wheeler and Protz recipe you list above would be for an approximation of Boddingtons Cask-Conditioned Real Ale not the tasteless garbage in the all-conquering widget can and keg served via the dreaded nitrogen dispense (yuuuckkk) don't get me started! Believe you me the *REAL* Boddingtons is a reasonably pleasing example of a fine Mancurian Cask-Conditioned Bitter, there are better and conversely there are worse examples than Boddingtons, what sets it apart from most of it's bretheren is that appearance-wise it is far paler in its colour and tarter in its finish than the norm, probably a fair starting point as a session beer for the Real Ale Virgin or Lager Lout. The Wheeler and Protz recipe seems pretty much on the mark for a Cask Boddingtons Clone, though I'd say that they're being a little modest/flattering? with the sugar content, you could probably stretch it to about 10% IMHO. It also could almost be made with the absence of or very little Crystal Malt if any were to be used keep it to the lightest. In a nutshell, YES the poor nitrokeg Paper Tiger lacks hop bitterness and aroma, (what nitro beer doesn't, too cold). The real McCoy has the usual pleasing (but not over-abundant) fresh bitterness and nice subtle hop aroma, depending on it's condition in the cask and how it's been handled. See out a Pub that turns over a fair bit of the stuff and you won't be disappointed! I remember my first pint of Cask Boddingtons, it was a Pub I can't remember the name unfortunately (perhaps somebody can), it was right across the road from where Jack The Ripper committed his last murder (East London?). It had an intentionally shabby finish inside and you could actually buy Jack the Ripper Memorabilia at there (books, T-Shirts etc). Touristy yes, but the Boddingtons was superbly fresh as were all their other beers. Ah shit! The name still escapes me! Later! Warren L. White Melbourne, Australia Someone please remember the name of the Pub???!!! _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Date: Mon, 25 Sep 2000 22:35:57 -0700 From: "D. Schultz" <d2schultz at uswest.net> Subject: double milling My HERMS has been suffering from poor extraction since I put it together. I fact, my all-grains have always suffered. After enough batches and closely looking at everything I can control, I bought a mill to work on that last variable - grain crush. Now I have but one data point to share. I opened the gap and ran the grain through. Visual inspection noted cracked husks but little of the white insides (what's the technical terms for this?) in sight. Then I decreased the gap and ran the grain through a second time per Dave's comments. The grain looked like empty husks and plenty of flour. I was sweating a stuck mash. The mash recirculated without a problem using a pump to recirculate. While I prefer a low pump rate, I found that I could run wide open without a problem. The grain bed was packed so tight, it was difficult to stir it. My IPA used 23 lbs of grain for a 10 gallon batch in a 10 gallon Gott. I stopped lautering when I had about 14 gallons as more wouldn't fit in my converted keg boiler for fear of a messy boil over. I was still at the 1.020 mark for the mash runnings. I think I could have taken another couple of gallons of wort. I haven't sat down to make any calculations yet but I can tell the grain crush made a big difference. Of course, I always felt my brew hop's mill was a bit coarse but they insisted everything was fine. I'm a believer in double milling. I will try some 'sperments on single milling soon just to test my observations. Burp, -Dan PS: O2 permeability rates to be posted soon. I realized I had a number of data points for plastics but not polycarbonate (plastic carboys). I will report when I have tracked that data down. Return to table of contents

It could have a chapter for each controversial topic. It would be as objective as possible, with each side getting its due. It would include references to critical scientific studies. It could finish each chapter with an informed summary. Frankly, I think a book like that would be among the most important in a home brewer's library. Great Idea, except there is one problem. Almost every subject in brewing has a controversy, and there is no clear answer to which argument is the truth....or ah....wait a minute....no, its the other way around. They do all have clear answers. No, wait. I think I had it right the first time. Good luck reaching a consenses! Return to table of contents
Date: Tue, 26 Sep 2000 06:00:20 +0000 From: William Frazier <billfrazier at worldnet.att.net> Subject: Wine question I grow and make wine out of French-American hybrid grapes. These grapes have too much acid to make a drinkable wine unless steps are taken to reduce the acid content, either before or after fermentation. I can usually get the acid content down to reasonable levels, but not always. I have a text that mentions the use of ion exchange to remove acid from grape juice. I'm sure there are HBD readers that have experience using ion exchange in their work. I would appreciate any information you might have concerning resin type/brand, equipment needed, technique, etc. I have a background in pharmaceutical research so I'm laboratory broken and look forward to trying a new method for improving my wines.

I have quite a bit of equipment, such as a lauter tun, grain mill and fridge with custom controller. I need a way to recognize defects. I can recognize a "rotten eggs" smell, but the others are just a guess on my part. Can someone steer me toward some information which will enable me to deliberately create certain defects (in small quantities) so that I can identify them. I have made about ten batches, mostly kits, but a couple of all grain brews. In general, I'm pleased with the results, but can't identify some of the "off flavors". I intend to keep trying until I get it right. Needless to say, this Listserv is my contact with the outside "brewing world". Jake __________________________________________________ Do You Yahoo!?

Date: Tue, 26 Sep 2000 07:10:10 -0400 From: "Kevin Kutskill" <beer-geek at home.com> Subject: plastics in brewing Al Beers and others have been wondering about fermenting in 5 gallon plastic water jugs: Having "been there done that," I wouldn't recommend it. The jugs are hard to clean, especially the hardened precipitate at the top of the jug. Then you scrub hard with a carboy brush, scratch the inside of the jug, and then your beers start getting infected (at least mine did). I blamed it on the scratches on the inside of the jugs--it may be hard to sterilize completely. If you use them, be careful of cleaning/sanitation issues.

Date: Tue, 26 Sep 2000 08:05:12 -0400 From: fridgeguy at voyager.net Subject: Teel pump Greetings folks, In HBD #3439, Drew Avis asked if anybody else is using a Teel 1P677A pump in a RIMS. I've been using this same pump for 3 years or so in my own system with good results. The pump is limited for use below 175 degF so don't try to use it for boiling liquids. The inlet and outlet connections are sized for use with 5/8" I.D. hose. My system is hard-piped in 1/2" copper water pipe, which is 5/8" O.D. Convenient :-) I simply use a 2" length of reinforced clear PVC hose at each pump connection and slip it over the copper pipe. Clamps on all connections prevent leaks. I haven't had any trouble with this setup and find the hose connections are flexible enough to allow me to remove the wing-nuts and slip the volute open to allow me to rinse out any grain bits that accumulate inside. I usually clean in place with PBW after scrubbing down the kettle and mash tun. Hope this helps! - ---------------------------------------- Forrest Duddles - Fridgeguy in Kalamazoo fridgeguy at voyager.net - -- Is your email secure? http://www.pop3now.com (c) 1998-2000 secureFront Technologies, Inc.

It's a Teel 1P677A, a mag pump that is no longer manufactured. Anyone else out there using this pump anymore? It has smooth plastic connectors which have a slight flair at the end - anyone know how to connect hoses to this sucker. The inlet and outlet are designed to have flexible tubing slipped on and to be hose clamped in place. The center connector is the inlet, the one on the perimeter of the housing is the discharge port. If the body of the connector is about 0.622" it is intended for use with 5/8" ID tubing.

Date: Tue, 26 Sep 2000 09:42:15 -0400 From: "Michael Maag" <MichaelMaag at doli.state.va.us> Subject: De-leading brass Randy asks: >>Was I right in assuming there would be no benefit from trying to de-lead the ball valves at that point? ( after 2 or 3 years of beer production) How much lead can you get out of a ball valve, and is it enough to be a health concern? What are the symptoms of lead poisoning? >> The de-leading process used by homebrewers removes lead from a few molecular layers of the brass surface. Your brewing removed that long ago. The amount of lead which can get into the beer from one or several untreated brass ball valves is negligible as a health concern. Adverse health effects from lead exposure are not seen until a person has a long term blood lead level over 20 to 30 ug/100 grams whole blood (for several years). The more serious symptoms are not seen until exposure of >50 ug/100g for around 20 years, or a single massive exposure. The symptoms of lead poisoning range from loss of appetite, metallic taste in mouth, anxiety, constipation, nausea, pallor, weakness, insomina, headache, nervous irritability, muscle/joint pain, tremors, numbness, dizziness, hyperactivity, colic, to seizures, coma,and death from cardiorespiratory arrest. Decreased sex drive, impotence, and sterility are also symptoms in men. I have used untreated brass ball valves and compression fittings in both my mash/lauter tun and my boil kettle for my last 50 brews. I also dispense through brass taps. I average at least 3 pints daily. My blood lead level is checked yearly. It is never above 6 ug/100g which is considered "background level" .

People have been talking about ways to sanitize long thingys like racking canes and hoses with a minimum of sanitizing solution... My solution (no pun intended) is to use a plastic wallpapering trough. It's made for holding wallpaper paste, and it's about 3 feet long, and about 6 inches wide by 6 inches high. Costs about $1.95 from mega hardware stores. Just a dribble of sanitizer and about a half gallon of water and you can totally submerge the pesky long hoses and canes without filling up a bucket...

At $5 per entry there is good money to be had. How and where to judge, that's a tough problem, but worth kicking around as an idea. I also have a big problem with all of these hard and fast rules, low boil high boil etc. What newbies need to know is that it is really really easy to make good beer. Follow that up with great beer will take more effort and experience! For all of the people I counsel who have made beer from a kit I give them these as ways to improve their brew in order of contribution to the overall quality of the beer: 1. Sanitation Sanitation, Sanitation 2. Full Wort Boil (no dilution) 3. Improved yeast handling (hydrate dry yeast, increase pitching rate, pitching temperature)) 4. Temperature control 5. All grain You would be surprised at how many new brewers would hear some of the things we argue about here (rapid boil is a good example) Can you imagine a newbie who is only doing a partial boil, say 2 gallons for an extract brew, with poor sanitation techniques, pitching a packet of dry yeast directly on the wort, and worrying about how vigorous his boil is? Don't laugh, when we make major issues of these trivial things some homebrewers will take these to heart over the basics. The emphasis for newbie should be on the basics! Return to table of contents

As a result, I worked up a recipe for an american pale ale using 100% wheat malt extract. I last made a batch for her about two years ago using Ireks canned extract. I just found out that Ireks has discontinued their wheat malt extract. Does anyone know of another dry or liquid 100% wheat extract? My understanding is that an all grain solution is very difficult, due to gumming of the grains. I did a 50% wheat 50% barley all grain batch for a hefeweisen once, and got a stuck run-off. My guess is that a 100% wheat all grain batch would be a nightmare. Anyone have any good solutions? Thanks Mike Return to table of contents

This is good, but let me add to this. The day or so before you brew, half fill your bucket with water and put in your beer fridge to get the water temperature down as low as possible - it really makes a HUGE difference when you finally add the ice.

This is also good, but if you can get an aquarium submersible pump ($25-$30), just plunge it into the ice water, and circulate to your heart's content and if you keep adding ice, you can eventually get the wort to almost 32F.

Date: Tue, 26 Sep 2000 08:53:09 -0600 From: "G. M. Remake" <gremake at gsbpop.uchicago.edu> Subject: Re: Boddingtons Hello all, Thanks for the replies to my request for help in formulating a Boddingtons clone for SWMBO. As Brad posted in Monday's HBD, according to Wheeler & Protz, Boddingtons Bitter is OG 1035, 7 SRM, 3.7% abv & 37 EBU. Their recipe is 92% pale malt, 5% crystal, and 3% sugar. This is pretty similar to the only recipe I found in the archives, but for the crystal replacing even less black malt (sounds right). The 37 EBU really fooled me (that's a BU/GU ratio over 1.05!); I suspected IBUs in the low 20s. Perhaps the lack of hops flavor and aroma fooled me, as well as the very low carbonation. So here's what I've decided to brew this weekend. There's no way I can duplicate a nitro head with so flat a beer, so I'll cheat a bit and carbonate to 1.5 volumes (outside the 0.75 - 1.30 guidelines) and include some head retention-improving malts. A bit of Carapils and wheat malt should do it. My OG target will be 1.040, but the recommended amount of sugar and a touch of flaked maize should lighten the body. I've got some Caramunich for the crystal, and the balance will be British pale. A simple infustion mash at 150F for 90 mins. seems appropriate. I'll bitter with EKG pellets and use only 0.25 oz. of homegrown Willamette flowers at 15 mins. for a hint of flavor and aroma as well as filtering aid, ending up around 30 IBUs after a 90-minute boil. I've already got a starter going with White Labs 005 British. It looks like I've complicated an otherwise simple recipe, but I've justified using up some left-overs, ending up with sort of an ESB-light. I think SWMBO will approve given the lower OG and bitterness,and if she doesn't, I guess I'll just have to dispose of it myself! Cheers! Greg Return to table of contents

Date: Tue, 26 Sep 2000 10:36:44 -0500 From: "Daniel C Stedman" <"daniel_c_stedman" at uhc.com> Subject: Wyeast 1272 experience I have encountered an interesting characteristic of 1272, and I thought that I would see if anyone else has experienced the same thing. I've recently brewed a batch of pale ale and a batch of porter with this yeast, and both batches have had a fairly tough skin of yeast left on top of them once fermentation is complete. I've never seen this with any other yeasts that I have used. It seems like the skin would actually provide a pretty good layer of protection against O2 pickup, so I guess I am not complaining. I actually used the skin off of the first batch to ferment the second batch (which I harvested 4 days after the start of fermentation, so it was pretty fresh), and it took off like a rocket. Are there any problems with harvesting the yeast on top, outside of flocculation issues (since I am potentially selecting the less-flocculant yeast)? I must admit that the porter is still pretty turbid, but it has only been a week since I brewed it... Also, does 1272 get funny at higher temps? I accidently let it get up to 80 deg F for ~8 hours during the first day of fermentation before getting it back down to the mid to upper 60's...

Schultz" <d2schultz at uswest.net> Subject: Oxygen Permeabilities of Plastics OK, here's the data from GE Plastics (units are cc-mil/24 hrs -100 in^2 - atm): Plastic O2 Perm. Typical use in HB'ing Polystyrene 434 not used much Polycarbonate 234 plastic carboys, airlocks Polypropylene 150 not used much High Density PP 110 not used much PETG (polyester) 27 soda bottles PVC 11 vinyl tubing The following data is from another source Low Density PE 500 fermenting buckets Polystyrene 330 Polycarbonate no data Polypropylene 190 High Density PP 185 *PET (polyester) 5 PVC 4 *PET and PETG are not necessarily the same. Sometimes PETG will be refered to as PET. Low O2 permeability data is noted for stretched PET (3.0) as is used in packaging but not bottles. While the number are somewhat off between the two data sets, the rankings are similar. I couldn't find a number for glass but seem to remember that it was measured in tenths. Also keep in mind that wall thickness plays a big part in permeability. The blow molded PC carboys will have a much thinner wall than the injection molded LDPE buckets. GE uses a calculation to determine the amount of O2 that would permeate through the wall over time: 02 (g) = (Px/100) * (Area * Time)/ Wall thickness where Px = Permeability coefficient Area = Surface area in sq. inches Time = Duration in days Wall thickness in mils (0.001's of an inch) So my fermentation bucket (LDPE, Px = 500) has an average diameter of 11" and a height of 17" and an approximate wall thickness of 60 mils. O2 permeation for 30 days = O2 (g) = (500/100) * (777*30)/60 O2 (g) = 1,942g of O2 or 64g per day. Since a PC carboy is about the same size and has half the permeability but also half the wall thickness, I estimate a smilar value for the PC carboy. That seems like an awful lot. 64g of O2 is 2 moles or 44.8 liters of gas at STP. What am I missing here? Regardless, Plastic carboys and buckets are very similar in O2 permeation.

I think we should start all fridge-related posts with a shout-out to Forrest! ;-) I have 12.5 cu. ft. chest freezer converted to fridge temps with a Johnson Controller. Works great - one problem. Condensation on the walls when opened and closed too much. I know. Don't open & close too much. But that's where the beer is! Condensation itself isn't really that bad but the inevitable black mold soon follows - underneath the kegs, on the keg's rubber parts, underneath carboys. How does a guy to cope? Emptying, cleaning and drying this thing out sucks. Hey, I got it mainly so that I don't have to lift 80+ lbs of beer up 3.5 feet - unless it's done 16 fl. oz. at a time! Any chemical treatments? The other option is to run the taps so that I don't need top open the top to dispense a beer. Since it's a chest freezer, running shanks through the sidewalls are out as with my luck, I will hit a refrigerant line. A serving tower on the top is an option, but what about cooling the lines within the tower? Plus, they would have to be easily detachable for when I open the fridge so that their weight doesn't rip them from that thin-walled top (even with minor supporting.

Date: Tue, 26 Sep 2000 12:44:38 -0400 From: Dave Burley <Dave_Burley at compuserve.com> Subject: Temper, temper Brewsters: Drew Avis asks my opinion if he should temper his malt by treating it to a small amount of water (called tempering) before milling and wonders if his sparge will run like a wombat in heat if he does both. The only real wombat I have seen was dead on a road in Oz. I guess he was just too slow, so I couldn't offer this as a comparator. But I'll bet if you follow my directions in the HBD archives you will have to slow down the flow with a valve to take an hour to sparge and get maximum efficiency in your extraction. In any event, professional brewers sometimes do temper their malt. I suspect the need has to do with the ambient humidity in the grain storage. In dry climates it might make a difference. When I tried it with my double milling procedure on my roller mill, I couldn't see any significant difference, but YMMV. Like everything I suggest, I always suggest you try it with your system, as this is easy to do. If you use a corona type mill, I would guess it might help, as this method of milling tends to be pretty brutal to husks. Keep on Brewin' Dave Burley Return to table of contents

I just returned from a trip to Alaska and was wondering if anyone had good recipes (extract) for the Alaskan Brewing Company (Juneau, Alaska) beers. Apparently their smoked porter (which was being brewed while I was there, seasonally only) is a major award winner. I enjoyed their Alaskan Amber, ESB, Stout, and IPA. It is far too costly to have it shipped here to Connecticut so making it myself is the next best thing. I know the guide (who seemed to know enough to be dangerous but not enough to be helpful) said he heard the recipe was published in "one of those brewing magazines" in the last month or two but didn't know the name. Assuming it was Zymurgy (which I don't get). FYI- a stop to the Glacier Brewhouse in Anchorage is well worth the time. They have great brews and although the place doesn't look like much from the outside, it is quite nice inside, and packed for lunch by 11:30. Thanks in advance.

Date: Tue, 26 Sep 2000 15:17:00 -0500 From: "Kevin Jones" <mrkjones at mindspring.com> Subject: 4 Inch PVC Sanitizer OK...I got lots of responses for details on my design for a 4 inch PVC container for sanitizer. Thanks for the interest. Its always nice when you feel like you have come up with a new idea to help make better beer. First the disclaimers. 1. All you engineers, plumbers, etc please feel free to help perfect the design/terminology. 2. I have only used this system with StarSan. 3. I accept all slings and arrows that come my way as long as they are constructive to the goal we all share...Better Beer! As mentioned in my earlier posting, I wanted a way to submerge long items (spoons, canes, hoses etc) in sanitizer without wasting so much StarSan and also make it easier to get long hoses filled without having to coil them in a bucket. I built a 4 foot high tube with 4 inch PVC. I included a screen plunger on a pole that rests on the bottom so the submerged items can be raised up out of the sanitizer for easy reach. I attached the tube to the legs of my wooden mashing platform with 4 inch worm gear clamps. For a visual, it works like the jar at the barbershop full of blue juice and combs. The Details Make the tube whatever length suits your needs/equipment. Mine is about 4 feet high. I made the first one with a screw plug (I think the plumbing term is "clean out"). This was not as good as I had hoped. It added cost, weight, and potential leak areas. Also, with the plug threads tight enough not to leak , it is really hard to remove again. My original thought was the "clean out" would be helpful in emptying and cleaning the tube. The second one I made only has an end cap. I recommend this simpler design. So far that's about 4 feet of 4 inch PVC with an end cap glued onto it. If you have never worked with PVC, it is very easy. Follow the directions on the glue can. The real trick to this system is the plunger used to lift the items out of the sanitizer. I used 5 feet of 1 inch PVC, a 1 inch end cap, a 4 inch PVC drain, and some fasteners. Glue the 1 inch end cap on the 1 inch PVC. The PVC drain I bought has to be adapted. It is designed to fit into the 4 inch PVC. The drain is open on one end and has a cross hatch drain grid on the other. It also has a flange that rests on the edge of 4 inch PVC. But we don't want it to rest on the edge, we want it to slide through the tube and be our basket at the bottom of the tube. Cut off the flange that keeps the drain from passing through the 4 Inch PVC. This is the only part that takes any craftsmanship whatsoever. I used a hack saw to rough cut the flange off close to being flush. I then use 100 grit sand paper and a sander to finish it off. As you work the flange down, you can test fit it into the 4 inch PVC. When it slips in and out easily, you are there. To clean up the rough texture left by sanding, just give it a quick rub with some acetone. Now you have a 4 inch cylinder, about 2 inchs deep, open at on end and a cross hatch drain pattern on the other. Using the center hole in the cross hatch drain pattern, attach the drain to the 1 inch PVC end cap. I drilled a pilot hole in the end cap, then use a wood screw and large washer ( have not found metal fasteners that don't turn back in the StarSan, I could use some advice here) to make the attachment. You should now have a long (5 feet) PVC pole with a drain attached to the end that will just slide into and all the way down into the 4 inch PVC tube. All the materials are on the same aisle at Home Depot except the fasteners. Mount in a vertical position in whatever manner suits your brewery. I used one or two 4 inch worm gear clamps. I put 5/8 ID vinyl hose over the clamps to give it some grip, then screwed them to my mash stand. Drop the tube through the clamps and tighten the clamps. I don't get the clamps too tight which makes it easier remove for draining and cleaning. Next fill with sanitizer and you are ready. I haven't measured it but I think mine holds about 2 gallons. From time to time I check the pH of the solution and add fresh StarSan (as recommended by StarSan) as needed to get back below 3, usually closer to 2. When the solution starts looking bad, dump it. One more Item you want to purchase on the PVC aisle are some plastic plugs that fit the 4 inch PVC. I think they are called "knock outs". Use the knock outs for lids, covering the tubes when not using the system. This helps to keep the bugs (big flying kind) out of the solution. I don't know about anyone else's experience, but flies seem to be attracted to StarSan. It kills them too, and at proper pH I have to believe that even a dead fly in the sanitizer does not invalidate its purpose, but I hate to see a dead bug in my sanitizer anyway. Hum...Dead Fly Ale....on second thought, maybe not. Someone asked about slime build up on things left in StarSan. This is a problem. When not brewing, I take everything, including the plungers, out and hang them up to dry. They are coated with StarSan, which according to the manufacture helps prevent contamination even during dry storage. Anyway, when ready to brew, insert the plunger first, then just drop everything in. For hoses, I usually bend them in half, then submerge bend first. One thing I have not done yet is locate a cheap brush that would work well to clean out the inside of the tubes. I'm thinking a long handled toilet brush, but haven't really looked yet. Please let me know your Ideas. Wish I could add some pics. With all the talk about upgrading/funding the hbd, adding the capability to show pictures this is something to consider. I have to go out-of-town for a few days, so give me some time to catch up to the e-mail/hbd postings when I get back. Drink Better Beer! Kevin Jones Music City Brewers Return to table of contents

In HBD #3439 Frank asked about low extraction...... >> and, according to the extract yields he listed, the gravity >>of my >>mash should have been around 40. It was 12. So, I ask you, good readers >>of >>this, the only online site I browse - what the hell happened??? My mash >schedule is the same as the last beer I made - a cherry stout that Frank, did you check the PH of the mash? My first all grain got horible extraction. I ignored the PH. Then I re-read Millers chapters on mashing. The mash PH should be in a range, I think 5.0 to 5.6. I adjust my PH to 5.3 using acid. Currently I am using phospheric acid. I think the mineral content of your water makes a big difference in the PH. Some people never need to adjust their PH. Others need to. There are a couple of brewers in town who switched from the tap water to RO filtered water purchased from a water treatment store. They do not need much PH adjustment now, and used to need quite a lot. Something else I did to improve extraction: I switched for the zapap lauter tun to an insulate cooler. Temp of the grain bed during sparge can effect extraction. I watch the temp of the grain bed. If it is below 160F, I use 180F sparge water. That increases the grain bed temp, and I believe extraction as well. I want to stay below 170 to avoid getting too much tannins. __________________________________________________ Do You Yahoo!?

Date: Tue, 26 Sep 2000 23:31:17 EDT From: RIPIC80 at aol.com Subject: sanitation I just wanted to say amen to Wil Kolb; As long as I have been brewing (not as long as him but 2 years), nothing other than bleach water and the rinse/heat dry cycles on my dishwasher have been used and my beer has yet to suck due to infection; those exceptions were due to my own inexperience with brewing. A 6 gallon bucket filled with water and about an ounce of bleach holds all that I need it too (including the lid sideways). The racking cane sticks out a little, but flipping it over halfway through the 30 minute soak has yet to screw up anything. Bottles get a rinse in bleach water, then into the dishwasher, where the rinse cycle is over 180 degrees, and one or two heated dry cycles has managed to keep all nasties at bay. The bottle caps go in the utensil holder and wash along with the bottles. And, to cap it off - you anal sanitation folk will shit I'm sure - half the time my cats are roaming around nearby getting a look and hoping for some spilled beer. I don't let them touch the bottles though they sure try. And as for the wand: I'm not sure about the rest of you, but my wand is in the damn bottles filling them. It takes less than 2 seconds to take it out of one bottle and put it in another. While one is filling I put another one next to the first one. Hell I even dump the beer in my overflow pot into bottles through a funnel into bottles, not always sanitized, to use as testers and have yet to be disappointed (the idea of a tester being if it sucks, I still have the properly cleaned ones, if not, cheers!). I realize that this is a bit cavalier, but until necessity forces me to change my habits, I'll be too stubborn/dumb/lazy to change. Of course, I knock on wood this whole time....
