I've brewed extract beer now for two years and now I want to upgrade to all grain brewing. I like the look of the Sabco converted keg but would like some advise before buying from homebrewer's with experience using it. How well does the Sabco full mash package (converted keg with false bottom, valve, thermometer, etc about $300) work? Is anyone using it to mash and then to boil after removing the spent grains? If so do you leave in the false bottom and will this effectively filter out the hops (whole or pellet)? Would I be better off with a Gott cooler mash tun system than mashing in the converted keg???

Are there any techniques for removing clorine which don't involve boiling? For example, during summer we are constantly fighting sunlight which removes the clorine from the pool - can I use this to my advantage and simply put water in a open carboy and leave it in the sun for a couple of days?

I just cannot let go of this one, especially when I read such puerile rubbish as written by Jethro Gump (yes, that is his real name). jethro sez: > In Australia, the plastic fermenting pails are ever so gently turned >in a lathe with decreasing grades of ever finer grit paper, such that there >is never a scratch evident to harbour bacteria!!! Ballyhoo and Balderdash! After much research, I have discovered that all of the world's plastic fermenters are made in Taiwan. Yes they are turned on a lathe, but it turns out that the *direction* is such that bacteria never settles in the grooves in the plastic surface in the Southern Hemisphere due to the Coriolis force causing the bacteria to settle in the *opposite* direction to the grooves. Hence, beer made in Australia in plastic will be infection free, but in the USA is guaranteed to be infected! Fortunately for our US readers, there is a simple cure for this. As nobody plays vinyl records any more, go get your old turntable out of the garage. It rotates clockwise, against the coriolis force in the Northern Hemisphere. If you put your plastic fermenter on the turntable (don't forget to turn it on), this will simulate a fermentation in the Southern Hemisphere, giving you a good, infection free fermentation. As for the oxidation risk, there is indeed less oxygen in Australia to permeate through the fementer walls (except Melbourne, granted). This is not due to a lack of cars and trees, but due to the incredible heat. Everybody should know about the effects of hot air...Again, there is a simple solution for this. Just ferment at 40C plus to reduce the oxidation risk. So Jethro, keep your redneck theories off the HBD, and just stick to making bloody gold medal winning barleywine. >Seppo's could learn much from this mob!!! Huh?

I mostly go by convenience more than anything else, I have a 10 gal plastic fermenter, and three 5 gal glass carboys. If I tie up two of the carboys in primary and then brew another batch when it's time to rack, I run out of containers. As far as breaking things go, I've only broken one carboy, but it was full of beer. I slid an empty one up next to the full one. They touched ever so sligthly and whoosh, beer and glass all over my feet. Bummer. I waited for the beer to wash away from the glass and started sucking it up, but I couldn't drink all of it. Wasted about a gallon I think <burp>. My question is why is the permeability of the plastic important? How does the air get in when the pressure in the fermenter is higher than that of the ambient air? Ed Return to table of contents

The price of an insipid sixer is small indeed >compared to the specter of *big brother* legislating proper beer styles. I understand and agree that Prohibition didn't do us [homebrewers] any favors, but I feel that MARKETING in the brewing industry has done far more damage to the American consumers than the government has. I agree with Ed Steinkamp's opinion on this one, and there's LOTS of POSITIVE examples of goverment regulation in the beer/wine/liquor industry. For example, industry regulation ensures that a novice appreciator of fine spirits won't get ripped off when they buy a $30 bottle of Scotch. Germany has their Reinheitsgebot for beer and France makes sure that a bottle of sparkling grape juice doesn't get labeled as Champagne unless it's from that region. Indeed, breweries and vinards can (and do) leverage off of these regulations to promote the quality of their products. This is all in the name of protecting the consumer (myself included), which, IMHO can't always tell the difference between marketing BS and the "real thing." Steve, you do have a good point about contacting the manufacturers, but there is no "arsenal of weapons to combat fraud" in the beer marketplace that I'm aware of, unless Consumer Reports now has a beer section. :) Writing a letter to the brewery isn't going to change their mind while their making money off of folks who don't know better. Anyway, I'll drink my homebrew most of the time and stick to buying local brands I know brew a quality product when I do buy. I think those who read HBD are educated enough to avoid copycat products, so maybe therein lies a solution: educate those around us about quality beers.

Don't worry, Jorge. No one will get sick off your beer, unless they drink too much! :) It's not possible for pathogens to grow in beer. I think the reason is the pH of beer is too low. Do we have anyone with facts and figures in the house? Jorge also writes: >I have another question. The bleach that you all use to sanitize your >carboys, does it contain chlorine or not? I sanitize with a product that >contains chlorine (HClO - sodium hypochloride) and also used another >product which contains ammonia. I rinsed with tap water several times until >there is no signs of these products. Did I work correctly? I am concern >that the chlorine could give some strange flavor to the mead. Personally, I prefer a product called Idophor, an iodine-based cleaner used by insitutions and restaurants to clean glassware. I can't remember the brand name off hand, but your brewing supply store should carry it. It's slightly more expensive than bleach, but the contact time is less and there's no question of "did I rinse it enough" since you don't rinse at all. A strange flavor could result in your mead if you don't rinse THOROUGHLY after using bleach. And: >I also need the dimensions for a copper immersion wort chiller (3/8" or >1/4" or 1/2" internal diameter) which allows me to chill aproximately 6 >gallons in a standard time (say 15 minutes). Any suggestions. I worked on >it and calculated that I would need aproximately 10 feet of copper >tubing. Am I correct? I will use tap water in the coils and will immerse >it in pot. I used 3/8" because I couldn't get fittings for 1/4" tubing to a 5/8" garden hose connection. Note that the smaller the tubing = quicker cooling, but you run up against the law of deminishing returns: smaller tubing = more backpressure = low throughput. Someone on the 'net has plans for a chiller if you want them (search the HBD archives), but I just went to Home Depot and bought a roll of 'fridge tubing and compression fittings for $20. I wrapped the tubing around a 1 gallon glass jug to make a coil. Take care not to crimp the tubing, though. It's a real problem on the smaller tubing sizes, esp. 1/4".

From: Timothy Sherburne <cchaos at northwest.com> Date: Sun, 20 Oct 96 20:26:52 -0700 Subject: RE: traveling beer There's been some discussion of bringing your beer on planes lately. I've got three points: 1) SEARCH THE ARCHIVES! This discussion seems to come up every couple of months or so. Learn from those who came before you... 2) Wrap it up. Put your bottles (or whatever vessle you choose) in garbage bags. I understand the fluctuations in cabin pressure can cause weak bottles to break or loose caps to come off. If you do search the archives, you may see a story where someone put their unwrapped beers in an overhead compartment. Later, during the flight, the person sitting under the beer got a shower... 3) You may need to prove that the contents of those suspicious looking, unlabeled bottles is actually beer. Another archives story: An overseas traveler was accused of trying to smuggle Molatov cocktails onto the plane, and needed to drink a randomly selected bottle to prove it was really homebrew. t | Timothy Sherburne | Creative Chaos | | Software Developer | cchaos at northwest.com | | Macintosh & Java | | Return to table of contents

This will give you a good idea of the work involved and the techniques used before you have to go live. Another text you may want to look at is "The Complete Handbook of Home Brewing" by Dave Miller, ISBN 0-88266-517-0.

But to try to turn a kettle into an insulated > cooler does not seem to make much sense. Jack, you make some good points and I am happy to accept your admonition that there is no harm caused by all the extra stirring of the mash, but I don't accept your analysis that I am trying to hit a nail with a screwdriver. I really like being able to store just one piece of versatile equipment rather than adding another bulky thing to my collection. Accepting that, then I'm sure you would agree that adding insulation to the kettle is a rational and useful enhancement of the system. To accomplish this, I've acquired some fiberglass water heater insulation. I'm cutting it to size, sealing the open edges, and adding some velcro so that the insulation can be easily applied or removed. I anticipate this will be a simple and effective solution. Depending on the results of a heat-resistance test, I may even leave the insulation on during the boil. I've been having trouble maintaining a six-gallon rolling boil on my range without a rather precise positioning of my kettle lid (which, to complicate matters, likes to shift around) . A propane burner is overkill and impractical in my apartment, but insulation may allow me to ditch to lid. So, as you can see, I am pursuing rational solutions for my particular situation. > If one chooses to use a kettle for mashing, we assume the one does so in > order to get better control of the process, viz. any temp at any point > during the mash. The price one pays for this capability is gas (heat) > and the need to stir. I found an inexpensive digital meat-probe type of thermometer at my local Lechter's Housewares which is very fast and accurate. Maybe it told me more than I should know, because I discovered that almost constant attention is required to keep the mash temperature correct and even. The temp differential between the center and sides of the mash in an uninsulated SS kettle can easily be several degrees. Stirring accelerates the heat loss, and adding heat tends necessitates yet more stirring to even out the temp. In light of this, the issue of control can be rather theoretical. A mechanized stirring solution such as yours certainly simplifies matters, as does a few dollars worth of boiler insulation and velcro Alex Santic NYC Return to table of contents
From: BRIAN F. THUMM <THUMMBF at GWSMTP.NU.COM> Date: Mon, 21 Oct 1996 08:01:49 -0400 Subject: Low Gravities Here's my problem: I consistently get low gravity worts. I mean...lower than I expect. I'm not a grain brewer yet, but I do some partial mash stuff and use lots of adjuncts / specialty grains. But, even with an extract brew, I would expect my gravities to be higher than they come out. I've even brought my hydrometer to work to calibrate it in the chemistry lab, and it's right on! For example, I brewed a recent batch with 6# light malt syrup and 1# crystal. I had also tried to mash 3# pumpkin with 1# Pale Ale malt, but I don't think I got good extraction. Even so, with a tiny bit of efficiency from the pale ale (I had good conversion temps in the mash), and a pound of crystal and 6# of extract in a five gallon batch, I would have expected a gravity near 50. I boiled for an hour in 3 gallons, cooled to 70 degrees, racked off the trub to enough water to make 5 gallons - O.G. of 36. Not even close! Am I losing gravity by only boiling in 3 gallons? Is my sugar getting irretreivably lost in the trub? If I were to boil the full 5 gallons, my trub would be lower in gravity, right? Thereby increasing the gravity of the wort? Am I on the right track? TIA Brian Return to table of contents

If you want an example of what that's like, take the asinine law that says beer is "beer" at one alcohol level, "ale" at another, and "malt liquor" at yet another here in California and some other states (an attempt at repeal in CA was recently defeated).

Things went relatively well, actually: The Recipe- 1 large (3 Gallon) Punkin 5#s Pale Malt 1#s Special B Malt 1#s Crystal Malt 1/4 cup Chocolate Malt 15ozs Libbys Canned Pumkin 1oz Cascades 1/4oz Hallertaur Nutmeg, ginger, cinnamon, clove, allspice, vanilla per your favorite pie recipe Irish Moss 1.5#s DME The Process- Boiled up 3 gallons water. Cleaned out punkin. Poured the boiling water (pay attention Murphy) into the punkin and steeped the insides for about 30 min. Drained the punkin (via my aforementioned EM knockoff) and used 2 gals to preboil the canned pumpkin. Mashed into the crushed malts inside the punkin at 150F. After about 30 mins, I had to decoct back up to 150 F from 135F. After another 30 mins, the punkin sprang a small leak in the bottom (Hello Murphy, what took ya so long?). I was able to collect the leakage and add to the boil pot. I sparged with 1.5 gallons 170F water and collected in the boil pot. 60 minute boil with Cascades at start, IM, spices, and Hallertaur at 15 minutes left. (I added 1.5#s of DME at beginning of boil, and steeped specialtygrains) OG- 1.050 Pitched a 1056 starter and got activity at about 6 hours. The sparge went pretty well. The runnings were deep orange turning to light orange as the sparge neared completion. The hydrometer tasting went well, too, although I couldn't get anyone else to try a sip. I'll update around Turkey Day when I plan to sample my first bottle. Greg (whatta) Guy- What does Robert Koerner say in his book about the relative Oxygen permeability of Polycarbonate? I usually clear my beers in a square PC carboy for about a week. Mr Gump made some excellent points about the treatment of plastic goods in The Land Down Under. His observation about the lower O2 content, while accurate, was credited to the wrong reasons. Where do you think all the CO2 from our northern brewing, purging and breathing goes? We all know CO2 is heavier than O2, right? Well, all our generated CO2 goes Down Under, and displaces more of their O2 back up to us.

From: dharsh at alpha.che.uc.edu (David C. Harsh) Date: Mon, 21 Oct 1996 10:26:56 -0400 Subject: Glass vs. Plastic/Aeration It has been claimed that: 1) Plastic carboys are more permeable to oxygen than glass and as a result will make bad beer. (BTW, I'm a glass snob) and 2) You need to buy an oxygen tank in order to provide sufficient oxygentation. (I use an air-sucking racking cane) The problem with the first claim is that nobody has ever really PROVEN how much oxygen is too much. Its a straight forward matter to calculate rates of permeation and total oxygen permeated at any given time - - but how much is too much? Data from the plastic fans indicate that it might be alot higher than many of us think, or the polycarbonate bottles are alot less permeable than we think. On the second claim, intial gravity, aeration and quantity of yeast pitched interact - if I pitch ~250 ml of yeast slurry that I get from a local micro (BarrelHouse Brewing Co. - great beers!) and aerate with my low-tech aerator I get fast starts and good finishes for an IPA. OTOH, I didn't expect that to be sufficient for the 1.094 doppelbock I made last month. So I point out that "optimum" aeration is an undefined term. I won't argue that pure oxygen gives you *higher* DO levels, but is it necessarily *better*? Waiting for data to prove something.

From: KennyEddy at aol.com Date: Mon, 21 Oct 1996 10:46:20 -0400 Subject: Killer Chiller Comments David Hill sez: "KennyEddy argues when discussing the killer chiller that several flat spirals mounted horizontaly one above the other in the wort chill better because they overcome the problem of temperature gradients forming in wort chilled with one horizontal spiral and no agitation. " Hmm...I don't remember saying that...my apologies if I wasn't clear or if my memory is failing me (wouldn't be the first time either way)... Actually I simply *asked* if this configuration would be better from a convection standpoint, and I was making a comparison to the "standard" *vertical-coil* (spring-shaped) immersion chiller where any convection of cooler wort is mostly down the sides (along the coils). One of your countrymen -- a well-known thermodynamicist who recently unsubscribed this digest (and will be missed, dammit) -- responded to me via private e-mail that he felt that agitation would probably not be necessary. A single flat spiral should chill the wort "more evenly" since the cooler wort is more evenly distributed across the diameter of the brewpot rather than being concentrated at the edges. Four flat spirals then should be better than one since the cooler wort "falling" from each coil is *further* cooled by the one below it (alignment effects notwithstanding) -- remember that each coil contains a "fresh" supply of cold water, whereas successive coils of a vertical-coil chiller contain increasingly warm water. ***** Ken Schwartz El Paso, TX KennyEddy at aol.com http://members.aol.com/kennyeddy Return to table of contents
From: "Craig Rode" <craig.rode at sdrc.com> Date: 21 Oct 1996 09:03:47 -0600 Subject: Whooops....IPA It was a beautiful weekend here in Wisconsin, and I took advantage of the weather to brew an American Pale Ale. While the beer was boiling in the vollrath on the cajun cooker on the back patio, I went to the front and raked the leaves. At the end of the session, after my immersion cooler had done it's job, I racked the wort into my primary, planning on leaving the hops and hot and cold break behind. As the kettle emptied, I noticed that an oak leaf had found its way into the brew kettle! How long it had boiled, I don't know, but it had boiled, as I always cool with a cover on. So..... Is this now an IPA? Am I about to find the real meaning of the word tannin? IMBR? Anyone with experience in the addition of leaves, let me know. thanks.

Get the liquid very cold, but slushy is not necessary, 2)Get gassed! Overshoot the desired CO2 level by cranking up those psi. (Warning: Don't blow you head, hand, or curious friends up. I find that the 40 psi max they state is quite adequate. Any more CO2 and I would suspect you're wanting to enter a belching contest.), 3)Shake it, no, stupid, I mean the brew. Shake the hell out of it, or until the bottle gets soft. 4) Repeat 2 and 3 until it can't take any more co2, 5) Relax..., 6)Take it off, after a wait (about the time of one homebrew) you can unscrew the cap and have minimal loss.

Before the first hop addition, I will scoop out the brown scum that develops around the side of my brew pot. Is this a smart thing to do? What is this material and does it serve any useful purpose?

I use corny kegs for both primary and secondary fermentation, as well as serving as you might have guessed. I hook up a blowoff tube by removing the gas intet valve and sliding a piece of plastic tubing over the post. I have not experienced any problems but I was wondering if anyone else used this same method or if anyone knew of any problems with using cornys in this way.

I guess this note is only slightly "brewing related", but soem readers may have some advice for me. Feel free to respond off-line. I just made my first mead. Does it matter what the OG is? I got 1.075; I think most people make it stronger, right? Do people rack meads to a secondary fermenter? Not knowing what yeast to use, I used a Lalvin wine yeast. should come out pretty dry I assume. Would an ale yeast have been better? - Bryan grosbl at ctrvax.vanderbilt.edu Nashville, TN Return to table of contents

I noticed this weekend that my fire extinguisher is empty. Then it hit me (an idea, not the extinguisher), could a regulator be screwed into the top of this thing, which could be filled with 2.5 lbs of CO2? The label says the limit is 300 psi. Has anyone tried this? It used to be filled with a special chemical. I assume that would have to be cleaned out somehow. The following question was posted a while back, but with zero responses I figured I'd try again... If a mash tun will not hold all the necessary grain for a batch, would it be ok to split the mash/sparge operation? Ok, it would take hours longer; but someone with a 5 gallon Gott could brew a barleywine. Is there any reason not to collect/sparge the first half, and let it sit quietly in the unheated, covered brew kettle until the second half is added later? I recently collected data from folks about the limitations of their mash tun, and this idea might help alot of brewers. Has anyone done this?

I keep reading about exploding 22oz. bottles and about the carbonation differences in larger bottles/kegs, etc. So how much should one decrease the priming amount for 22oz bottles vs. 12 oz? Becks: I am learning more about beer because of homebrewing and the HBD. Now that I know what light struck/skunked beer smells like, i.e. Heineken. I had a Beck's Dark this weekend and it had a slightly skunked smell. I used to really like Beck's dark. Am I getting pickier? Is Beck's dark lightly skunked deliberately? Is it just the green bottle that might have been sitting on a shelf long enough to get skunked? Guiness: About 16 or 17 years ago a college friend who had stayed in England for the summer had me try his favorite beer, Guiness Stout. He was very disappointed that it didn't taste like the Guiness he had in England. I couldn't drink the whole thing the first time and even though I drink it occasionally now I think I prefer a smoother Irish Stout like Murphy's. At any rate, after reading so much about Guiness and how different the draft version is, I finally had Guiness Stout on draft at Rose & Crown Pub in Lewes, Delaware and I'm glad I did. It had a creamy head that stayed with it and was smoother and certainly less alcoholic than the bottled version. Very different and distinctive. Sorry for the BW, hope someone else had a similar experience with their first Guiness Stout draft and can relate. John Penn Return to table of contents

This is >a recurring issue on the HBD that needed correcting. That's it. I'm certain >that even my rantings will make zero difference, and we'll still see this >type of statement again in a few months. You are mistaken. The thread was started because Dave Burley claimed that one brewer's infection problems were most likely caused by his using glass carboys and Charlie Papazian's blowoff method of fermentation. Dave asserted that the difficulty of cleaning the carboy was the source of the infection. I posted a rebuttal claiming that Dave was the first to post that plastic fermenters are easier to sanitize than glass and that this statment is "baloney." I also put in an auxilliary comment saying that lagering in plastic is likely to cause oxidation of alcohols into aldehydes. Suddenly, the HBD was filled with more than a half dozen posts from Australia and elsewhere making all kinds of claims in defense of plastic fermenters. There were claims that because water vapour does not pass readily thorugh HDPE that oxygen would not either. This is incorrect. The permeability of a plastic for one gas is not related to the permeability of another. For example (from the Cole-Parmer catalog, plastics physical properties table), LDPE has a permeability of 60 for O2 and 280 for CO2 (units throughout this post will be ((cc-m)/sec-cm^2-cm Hg))*10^-10) where as for nylon, O2 is 1.0 whereas CO2 is 1.8. There was a claim that polycarbonate was less permeable than HDPE because it has a "tighter molecular structure" or somesuch. Wrong again: O2 for HDPE is 10 whereas O2 for PC is 20. Then there was the assertion that since the beer is saturated with CO2, that O2 would not dissolve in it. Absolutely wrong! That's simply not how gasses work. Then someone said that HDPE must be O2-barrier because any food or milk that we got in HDPE would be oxidized. Guess what? It is. When I opened my HB supply store, O2-barrier packaging was almost impossible to find, certainly among homebrew supply distributors (now they have it). I searched high and low and finally found two types of plastic that were made specifially to be oxygen barrier. One week in 2mil HDPE was equivalent to 2.5 years in the plastic I had found. This was for hop storage, incidentally. The other plastic I found that was O2-barrier (and I use for whole hops) is made for the meat packaging industry! After all this, I would like to point out that it is the seal on the plastic fermenters that is suspect and not the oxygen permeability of the actual walls of the fermenter. They are indeed more permeable than glass, but at the thickness of the plastic (probably a hundred times that of a plastic bag) the permeability through the walls is not really an issue. Only two of the five HDPE fermenters that I have downstairs have gasketted lids. The others just press-on. I never meant for this to become such a battle and I don't have any bad feelings for anyone who posted rebuttals to my post. Again, please recall that I was defending glass, which (in my mind) is inferior to plastic in price and durability. *** I'm just now getting used to using Pegasus mail and lost the text of one poster who posted that A-B uses sterile air to scrub hot wort. This was in their "Beer University" or whatever they call it. The fact is that A-B uses NITROGEN and not AIR to scrub DMS out of their hot wort. I guess that to the people that put together the class, "nitrogen gas" sounded too scary and they figured that since air is 79% nitrogen, it's okay to substitute "air" for "nitrogen" in their lecture. A-B's class may have been entertaining, but it was far from accurate. Al. Al Korzonas, Palos Hills, IL korz at xnet.com Return to table of contents
