---------------------------------------------------------------------- From: Kevin Kane <kkane at uidaho.edu> Date: Sat, 24 Aug 1996 17:27:07 -0700 (PDT) Subject: Bleach residues Robert Ray asked about problems with his brew in regards to bleach. Sure, iodophor is good stuff (especially for SS kegs), but bleach leaves virtually no residue. Bleach is a solution of sodium hypochlorite, made by the reaction of chlorine gas and sodium hydroxide. What remains after a sterilization with bleach are sodium chloride and sodium hydroxide. Using the amounts prescribed by a number of homebrew texts, these compounds are going to be in such low concentration that they won't affect flavor or wort pH, even if you don't rinse. I've NEVER had spoiled beer from using bleach. Robert, I'd check elsewhere in your brewing steps. If you're using a starter, make sure that everything in contact with it is sterile, and that your starter is viable before you pitch. Also, check to see that you don't present an opportunity for bacteria to get to your wort before the yeast do. Kevin M.

From: Aaron Sepanski <sepanska at it.uwp.edu> Date: Sat, 24 Aug 1996 22:09:27 -0500 (CDT) Subject: Irish Moss I noticed Ken's post on irish moss, and I felt compelled to reply in defense of IM. I use it in all my beers. Never have I had a problem. Nor have I ever observed anything close to what you gentleman have described. There was a time when I didn't use it, and my beers were hazy. Since I started using irish moss, I've noticed a great difference (night and day). I not sure that what the othe person that responded to Ken's post said was right. I don't know if it is correct to add irish moss half way through your boil, or after a rolling boil is established. I've been told to add it 15 minutes before the end of the boil, and have been doing so with excellent results. If your boil is an hour say, the moss is in there an extra 15 mins. and maybe longer. Whether or not this makes a difference, I have no idea. But hey its worth a try right? The only way to improve the quality of any of your beers is to experiment. Thanks for taking the time to read my post, Aaron Sepanski P.S. I also noticed that you said it takes you 15 mins. to get your beer to stop trying to boil over. I do it in about a minute. Let it rise up so you know that you have completely established a boil, then before it boils over, pull your kettle off the heat and let it sink back down. You may need to do it twice, possibly three times, but it works. Hope this helps, because boil overs suck (extremely difficult to clean). Thanks guys. Return to table of contents
From: Aaron Sepanski <sepanska at it.uwp.edu> Date: Sat, 24 Aug 1996 22:19:48 -0500 (CDT) Subject: Bleach for sanitizing To respond to Robert's post.... I use bleach to sanitize as well. I have been forever. I have never had a problem at all. I know that bleach can leave a film, you only have to pour a little on your hand to find that out. Because of this, I make sure that rinse my carboy completely! I rinse it out until I can't smell the bleach anymore, and then rinse 2 more times after that. Furthermore, when I rinse, I never come close to filling my carboy with the rinse water. I simply fill it about a quarter full and vigorously shake the water around in the carboy. It would seem to me that it might be difficult to agitate 5 and 6.5 gallons of water. Isn't it heavy? or do you not agitate at all? At any rate please don't feel as though what I'm saying is that you are in correct. I'm sure your method is just as good a clearing the bleach. I am merely suggesting a different method that might make life easier for you. Good luck on your next batch all. Thanks for taking the time to read my post, Aaron Sepanski Return to table of contents

As somene interested in the homebrewing of root beer (particularly from all-natural ingredients or, at least, using those ingredients to greatly enhance the available extracts), I come to the homebrew list with a humble proposition: If you will either post to the list or to me privately any/all experiences, recipes, history or whatever that you have on the subject of home-made root beer, sarsaparilla, birch beer or whatnot, I will do my best to combine it with info I've already collected and produce a FAQ or proto-FAQ for everyone's review. I know this isn't the primary purpose of the list, but enough people in the homebrewing world seem to have an interest in this that I figured it'd be a good place to start digging. Any takers? :) Regards, Greg Brooks (gbrooks at concentric.net) Return to table of contents

From: dflagg at agate.net Date: Sun, 25 Aug 1996 09:46:50 -0400 (EDT) Subject: bleach heresy? Ray Robert asks: > Does bleach promote growth of bacteria in beer? I doubt it seriously!! What is happening to you maybe what happened to me a while back. I would pitch a good chunk of temperature normalized yeast slurry, and then....nothing. Or in come cases, a very anemic fermentation slow to start. Problem drove me up the wall. I was fermenting in 6 gallon carboys, and would keep a bleach solution in them between uses to keep the bugs down. Then, when I was ready to use them, I would rinse them out with cold water, using three or four rinses. Well, after some expert help from this forum, I finally found what my problem was: Bleach does not mix very well with cold water. It will leave a film on the glass. I switched to rinsing with -hot- water and my problem went away. Prove it to yourself with this simple experiment. Dip your fingers in some bleach. Feel how they are slippery. Now, rinse your fingers with -cold- water. They will still be a little slippery. Rinse again with -hot- water and notice the slippery surface goes away. So the rules are: If you are soaking with bleach, use -cold- water. The germ killing power will last longer. However, if you are rinsing, use HOT water. ************************************************************ Doug Flagg | "A Homebrew a day... dflagg at orono.sdi.agate.net | Keeps the Worries away!" ************************************************************ Return to table of contents

From: Kirk R Fleming <flemingk at usa.net> Date: Sun, 25 Aug 1996 19:42:07 +0100 Subject: False Bottoms In #2157 XKCHRISTIAN at ccvax.fullerton.edu asked: > 1. In using a recirculating type system (RIMS), is an Easy Masher setup able > to produce good results? Is a copper tube around the bottom (with hack > saw slits) better? Or is a false bottom the only real choice? Since I'm going to provide a viewpoint of design issues, I need to answer the questions above explicitly, so there is no implicity answer assumed. I've not used an Easy Masher for RIMS, or a copper tubing manifold so I don't know how well they work in the RIMS environment. OTOH, I doubt a false bottom is the "only real choice". Schmidling has claimed it's a total waste of time, and he has a point. Read on. > 2. I am thinking that a false bottom is going to be the best route to go. > What is the optimal size of the false bottom (9, 10, 12 inch) and what is the > optimal spacing/size of the wholes? the false bottom will be made of SS. "Optimum" size depends on all your basic engineering factors. If you're building it yourself from stainless, then the optimum from a cost/time perspective is infinitely small. If you only care about flow rate thru the plate, then optimum is infinitely large (if you're using a real pot having finite diameter, then optimum would be pot diameter). > 3. If I choose to go with a false bottom for both the boiler and the mash > tun, is scorching a problem when doughing in and boiling? Since doughing-in is done at around 100F or so, scorching should be a non-issue. During boiling, the wort is pretty much free to move around on its own, so I don't see how a false bottom would do too much to influence scorching. I never had a problem with scorching in the kettle with a false bottom. Unless money is no object and you just insist on using whole leaf or plug hops, I don't see any advantage to a false bottom for the kettle--use pellets instead, or use a hop bag. In #2158 GuyG4 at aol.com offers some advice on this issue: > The false bottom is probably hydraulically the least efficient, as it > doesn't take advantage of pressure relationships in overlying and > surrounding saturated grain to move wort, but rather is another point source > sink, which may draw preferentially from the grain-vessel boundary. I have no idea what is meant here by efficient, but I can see no way that a false bottom drains a at a point, nor why it there would be any preferential flow at it's periphery. The comment here regarding pressure relationships is also kinda baffling--even during recirculation, I'd model the situation as more-or-less hydrostatic/quasi-static. Given the false bottom is reasonably far away from the real vessel bottom, and that the drain is in that real bottom, flow across the entire false bottom should be uniform and constant. > A manifold tube stuck into the middle as a drain is probably hydraulically > most efficient, because it draws from each slot, rather than just the point > of attachment. A circular manifold is much worse, because it induces flow > along the grain-vessel boundary, and not through the middle of the grain. Again, I don't get it. I think the first statement implies that an Easy Masher experiences flow only into that portion of the screen very near the drain pipe, and very little wort flows into the screen near the rolled-up end. But, it also implies (to me) that flow thru a false bottom only occurs at some localized area. It's intuitive that as the distance between the false bottom and the real bottom goes to infinity, the flow across the false bottom becomes uniform. As that distance approaches zero, the flow across the false bottom goes to zero except in the region where the false bottom is directly above the drain. The final comment regarding a circular manifold inducing flow at the periphery of the vessel makes sense--if the manifold is at that periphery. What if the radius r of the manifold is 2/3 the radius R of the vessel (or some other number)? > Of course, false bottoms are easier to stir over than manifolds. By far. This statement is pretty significant--one of Schmidling's comments regarding the coolness of the Easy Masher is that stirring is possible without making a mess of the wort. All design issues need to be bounced against stirred vs static mashing. Some brewers think stirring is a Bad Thing, some think it's a Good Thing. GuyG4 responds to question 2. regarding false bottom size with: > Optimal diameter is a matter of opinion. I personally would minimize > foundation water and maximize flow through grain (rather than flow along > grain vessel boundary) by minimizing the area of the false bottom. Got another problem here, too. Clearly the smaller the false bottom the less the flow thru the grain. As the false bottom diameter approaches zero, mustn't the flow approach zero? Imagine there is no 'real' vessel bottom to effect flow. If the false bottom is exactly the diameter of the mash vessel, and the sides of that vessel are perpendicular to the false bottom won't all mash flow be perpendicular to the plate? And won't the flow at the center of the mash tun be identical to that at the periphery? Now imagine another design, a conical-bottom mash tun with the false bottom near the bottom of that cone (minimize the false bottom size). Now, flow at the edge of the tank is parallel to the conical tank wall, convergent at the false bottom. Flow will by greatest at the center of the grain bed, and minimal at the edges, but will certainly not be uniform. > Optimal spacing of the holes is about 50% mean grain diameter, which is > about 3/32 I think. Someone else I believe knows better what grain size > curves are like for optimally crushed barley. I've used both 3/32" and 5/64". Both work wonderfully. Back to false bottom size though: if you're using a Sankey keg for the mash tun, then a large false bottom (about 14.5" diameter) provides a very nice balance between a large flow area (and uniform flow) with an acceptably large volume under the false bottom to prevent scorching (about 3 quarts). Alternatively, an EM is probably going to be far less expensive that a false bottom, and is conducive to mash stirring (which, in my experience will improve yield a lot). Finally, the issue of clear wort may come up. Use of a false bottom, no stirring, and moderate recirculation will produce crystal clear wort into the kettle. Why this is important escapes me, although it is very satisfying. I've not seen any difference in finished product clarity either way, although I might miss chill haze others would notice since I drink cool ale, not cold.

My last batch I noted a discrepancy between the reading on the dial and reading on my outside thermometer, so I bought a new dial type and compared temps. Yes, my old one reads 10 degrees hot, so my beer has some distinctive character notes. The question is, what type of thermometer is favored for mashing, and what sort of calibration procedures do experienced homebrewers follow to ensure their thermometers read consistently batch to batch? >> I looked at my dial-type thermometer and it says right on the face that the probe must be at least 2 inches into the liquid to get a accurate reading, however I wonder it the reading is inaccurate if inserted all the way?

From: FelixTKatt at gnn.com (Mark Andrizzi) Date: Mon, 26 Aug 1996 09:55:21 Subject: Bleach This is in response to the post from Ray Robert as to using bleach for disinfection and the potential to killing yeast; I have been brewing for many years and always use bleach to disinfect everything that I use in the brewing and bottling process and have never had a problem with my yeast OR contamination. If you use a SMALL amount of bleach and rinse well, you should have no problems. It does not take a large amount of bleach to disinfect. If you do use too much bleach or fail to rinse, then you have have a problem with killing the yeast, in addition to killing yourself with the ingestion of bleach. Use sparingly and rinse.

From: cschroed at ball.com (Curt Schroeder) Date: Mon, 26 Aug 1996 08:22:40 -0600 Subject: Hops Harvest Problems Last night I went out to start harvesting my Centennial hops. I noticed a half a dozen wasps and bees buzzing around. A few stings wasn't gonna stop this brewer. I climbed the ladder and was shocked to see the top 3 feet of the vine was really sticky and covered with little white things. These things are about 0.1 inches long and 0.01 inches in diameter. Close examination showed that they were not moving, however there were a large number of aphids on the leaves as well. The wasps where eating the aphids. Good job wasps! (no affiliation just like the job their doing). When I picked them I put the ones that were wooly with the white things in a separate sack. I was thinking about dumping them in water to clean them but I think the stickiness will keep the white stuff on. Right now I have them in my drying room. They smell great much stronger that the non sticky cones. What are these white things? Are these cones ruined? Is there something I can do to save them? BTW I live in Colorado where the weather is very dry so I doubt its any kind of mold.

From: dharsh at alpha.che.uc.edu (David C. Harsh) Date: Mon, 26 Aug 1996 10:59:59 -0400 Subject: Bleach Lots of recent talk about bleach and sanitation: 1. The vast majority of bleaches are NOT sodium hydroxide, they are sodium hypochlorite, i.e. chlorine bleach. Chlorine bleach is fine as a sanitizer, but be sure to rinse, rinse, and then rinse, again! BTW, this is what I use leftover Budmilloors that people bring to my house and don't consume - rinsing carboys! After all, a beer with no flavor certainly isn't going to contribute an off flavor! Personally, I favor iodophor for sanitation, but that's not the point. 2. BIG WARNING ON CLOROX! Clorox has switched formulation and is no longer chlorine bleach, it is now using lye. Sodium hydroxide is not recommended as a sanitizing agent. Also, the high pH (strong alkalinity) may cause deposits of mineral complexes in your carboys that are not soluble at pHs above around 2.5. These deposits shouldn't affect flavors, but might provide spaces for contaminates to hang out and cause problems. This is a good reasons to stick to low budget el-cheapo bleaches. 3. As far as the shop owner that claimed bleach was bad because in killed *all* the bacteria.... Just to make it clear: bacteria in beer bad, yeast in beer good. (lambic exclusion rule noted) 4. When the entire discussion started, Ray Roberts said he had always used bleach and had only recently started getting infections. Got any old plastic parts, Ray? A new racking cane might solve the problem - likewise for any other old plastic parts.

From: CSS2 at oas.psu.edu (SPEAKER.CURTIS) Date: Mon, 26 Aug 1996 11:18 EDT Subject: re: dry hopping & new bubbles David Luegs <leud at calvin.edu> asks about drying hopping changing the rate of bubbles through his airlock: I have seen this phenomeneon before too. The most likely explaination is that you have a solution (beer/wort) that is saturated with CO2. By adding the hops to it, you provide a nucleation site (something physical for the bubbles to form on), so now some of the CO2 can and does come out of solution. The last pale ale that I dry hopped did this - but the higher rate of bubbling continued for almost a week! Be sure to use some type of strainer when you siphon your dry hopped beer into the bottling bucket or keg to keep the bits of hop out. I (stupidly) neglected to do this on my last batch, and my pale ale has hop floaters :-O A muslin hop bag slipped over the end of the racking cane works very well; it just looks funny... Cheers!

From: bill-giffin at juno.com (William P Giffin) Date: Mon, 26 Aug 1996 13:03:02 cst Subject: Brewing water Good afternoon all, Why is it important to try to duplicate the water of the type of beer you are brewing, for example Burton water which has 1,200 ppm of total dissolved solids in its water. I read that Calcium is required in the brewing process yet the water of Pilsen has very little calcium and my water is very similar to Pilsen water and I have brewed many different styles of beer, that were to style or very close to style. All my batches have been all grain and I have had no difficulty in any way brewing many different styles. Lets go back to Burton water if the water is unadjusted how much of the solids precipitate out of the wort during the boil? How much sulfate is required to give the hop character of a Burton pale ale? I have brewed bitter where I adjusted the water to Burton, added a small amount of gypsum to the mash for pH adjustment and adjusted the pH using lactic acid. All the beer tasted about the same. It would be hard to pick out which beer had the most sulfate. Do we have to adjust our brewing water to achieve the style we want or can we do a good job of brewing by just getting the pH of the mash and the sparge water in the appropriate range?

After all, a thorough rinsing (I usually >triple-rinse with hot water) should do away with any harmful residue. i've used bleach for a while now, and haven't had any big problems. i rinse pretty well with hot tap water, and nothing bad has gotten me yet. for stainless kegs, i use iodophor, but that's the only thing i use iodophor on. there was a question about lagering at higher temperatures. all the benefits of lagering can't be achieved at higher temps (certainly higher than 50F), and it's basically because the yeast activity is very different depending on temperature. a lagering at cold temps (mid to high 30's F) causes the yeast to reingest certain compounds in the beer (sorry, no beer books on hand), and this reingestion helps to smooth out the flavor of the beer. there are other bio/chemical changes that take place in the beer, i think, but i've no reference with me at the moment (cue, lager experts). so, temperature is really pretty key if you want to do a true lagering. now, is it possible to "lager" in the bottle, as soon as fermentation is over and the beer is packaged and a short (warm) period for bottle carbonation is given? i've done this, but i've no idea if the beer benefitted from it. i should have done an a-b comparison. i would imagine it probably does help a little, but there are some geometric/surface area issues that may come into play. i may go look all this stuff up and repost later. until then, brew hard, mark bayer Return to table of contents

From: Kurt Schilling <kurt at pop.iquest.net> Date: Mon, 26 Aug 96 12:14 EST Subject: RO water and off flavors Howdy fellow brewers: I have a question that was asked of me at a brewclub meeting over the weekend. I frequently get asked to give opinions on the taste of homebrews (one of the hazards of owning a brew shop). Residing in central Indiana where the water is both quite hard and alkaline, many people are using RO water for their brewing. Their beers end up with an off flavor that seems to me to be phenolic (band aid-y). This flavor even shows up in brews that have been fermented below 70F. Yesterday, in sampling a steam beer that had been made using RO water, we thought that we detected a metalic taste (zinc?). So, here is my question: Can unadjusted RO water (no ions added, ie Burtonized) leech metalic ions out of stainless steel and brass fitings? As to the phenolic off flavors, wild yeast, high temps, and excess chlorox are teh likely culprits. It is quite possible that the local water departments are using chlorimines as a chlorine source. That being the cse boiling the tap water just gives you water that still has a high chlorine content. I noted in one of Dave Burley's postings in HBD 2159, that iodophor can also contribute off flavors if missused. What about products like One Step? I'll be glad to summarize responses if any comein via private e-mail(which is fine). Thanks, mes amis!! Kurt Schilling e-mail kurt at iquest.net Return to table of contents

Trub, being a condensed almost gelatinous mess can easily go anaerobic. Best bet is mix it up (aerate) with the rest of your pile. If your compost is active, I don't think a little trub could kill it. I usually compost my trub, never had a problem. Lou Heavner <lheavner at frmail.frco.com> Return to table of contents
