Doing >> this again with a small portion of barley and resting at 65'C, it thins >> right out. I know another brewer who has had the same experience. > >That sounds like a protease effect, not an amylase effect. Did you try >doing the 65C rest _without_ adding malted barley? It does sound like protease, but it can also be what's called "liquifaction," I believe. Liquifaction is done by alpha amylase and is the breaking down of starches into dextrins and smaller carbohydrates. 65C is at the low end of the amylase range, where beta amylase is active along with alpha amylase. I don't know whether or not wheat malt has both alpha and beta amylase, but I suspect it does. Wheat malt actually has a lot MORE amylase than barley malt. Protease is most active between 55C and 60C, so I would rule out protease acitivity at 65C. *** John writes: >OK, now for a crazy idea: has anyone used the blowoff to collect yeast? Sure, Bass, Marston's... the priciple behind the Burton Union system includes (among other things) the ability to collect yeast via the blowoff. The problems for us homebrewers is sanitation and, as John said, separating the yeast from the "grimy blow-off." Another problem might be that if the yeast is very flocculant, you may blow off too much of the yeast. *** Aaron writes: > I also heard that dry hopping or using a hop-back will improve >the head retention of the finished beer. I too have read that hops do improve head retention, but I suspect this was boiling/flavouring hops. Oils always reduce head retention and it's the oil of the hops that you are interested in (are extracting) during dryhopping. *** Steve writes: >Tim Fields complains of carbonation problems even when he used a lot of >priming sugar. That reminded me of something... did you boil the bottlecaps to sanitize them? If so, the plastic liners may have deformed enough so that a tight seal is not made with the bottle. Al.

Date: Fri, 15 Sep 1995 16:25:45 -0700 (PDT) From: Brad Owen <bowen at mindcrime.ax.com> Subject: 3068 Weinstephan Yeast Another data point on this thread. I have a batch of beer with this yeast that has been fermenting for nearly 3 weeks now: 5 days in the primary and the rest in a secondary. Does this yeast never quit? The temp has been about 70--as close as I can tell since I don't have a refrigerator to ferment it. The recipe is half barley half wheat 8lbs total (extract recipe). I think it should stop by this weekend since it is down to a bubble about every 40 seconds. Odd thing is, I took a gravity reading when I racked to the secondary and it was at 21. 10 days later it was still at 21, although fermentation had continued steadily. How can that be?

Date: Fri, 15 Sep 1995 19:45:53 -0500 From: ajdel at interramp.com (A. J. deLange) Subject: Water Treatment Concerns/Weissbier In No. 1825 Phil Hofstrand asked some reasonable questions about how to use the water formulations which have been posted recently. While I tried to make this point several times throughout the series it is worth repeating: The series tells you how to formulate, for example, Munich water but not how to use it to best effect with best effect meaning the production of a beer which closely resembles the target style. To acheive this you must emulate the practices of the brewers in the target city. If you use Munich water as is to make a dark Munich style beer you will probably be successful because the original Munich brewers didn't treat their water. They didn't know how. That is why the dark Munich beers are the way they are. Eventually, along came the industrial revolution with its technology and understanding of water chemistry. Removal of the carbonate hardness drops the alkalinity of the water enough to make it possible to produce the soft a helles style beers. Thus you must remove the carbonate hardness as well (or not add it in to begin with) if you are to produce a good representatation of a Helles. Phil asked about whether brewing practices, in particular large volume reductions in the kettle, influence the concentrations of ions in the beer. I think the the answer to this must be "yes" but what actually happens may not be that easy to determine because of the variety and complexity of the reactions that take place in the kettle and fermenter and the fact that many of the inorganic constituents of the final product come from the grain as well as the water. For example, the fermentation of lagers brewed with extremely soft (low sulfate) water are often accompanied by the production of incredible amounts of sulfides where the sulfur comes from certain of the amino acids in the malt. Which brings us to Phil's final question as to whether the association of sulfate with hops bitterness is due to an organoleptic synergism between sulfate ion and hops components in the beer or a reaction between them in the kettle. I certainly don't know the answer to this but note that sulfate in the kettle enhances the floral aroma of hops in the beer and as one cannot smell sulfate ion conclude that this must be due to a chemical reaction in the boil. I suppose the same could be true of flavoring components but the principal reaction in the boil is one of isomerization. On the other hand sulfate synergistically enhances impressions of bitterness especially in the presence of magnesium and malt supplies a fair amount of magnesium to the finished beer. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * In No. 1832 Don Rudolph wrote about ester and 4-vinyl guaiacol production in Bavarian wheat beers. The explanation given for 4-vinyl guaiacol is actually accurate for ester production i.e. it is esters which are produced as by-products of amino acid metabolism. The products of this metabolism contribute to the oxyacid pool and some of these acids are reduced to higher (fusel) alcohols. These react with acyl-coenzyme A compounds, derived from acetyl coenzyme A (from pyruvate) and fats, to form the various esters. High temperature tends to promote formation of both fusels and esters. Limiting oxygen during the growth phase makes acetyl coenzyme A which would otherwise go into sterol synthesis available for acyl CoA and hence increased ester formation. 4-vinyl guaicol, conversely, comes from decarboxylation of ferulic acid which is bound to the pentosans in malt. Given a yeast that are able to do this (pull off the CO2), the most important factor in production of this stuff is that the ferulic acid be unbound from the pentosans. Warner indicates that this is facillitated by a rest at 44C at pH 5.7. I can't agree that Warner recommends pitching at high temperature. He cites a rule of thumb for superior weissbier which calls for a pitching temperature which, when added to the fermentation temperature. gives 30C. He states that common practice is to pitch at 12C (54F) and ferment at 18C (64F). He also gives an example in which the yeast are pitched at 17C (63F) in which case fermentation is carried out at 13-15C (55-59F). I have always used the 12/18 combination with the Wyeast 3068 and have always been pleased with the clove/bananna balance. The bananna seems to disappear after several weeks, however, but the clove remains strong. A.J. deLange Numquam in dubio, saepe in errore! ajdel at interramp.com Return to table of contents
Date: Fri, 15 Sep 1995 17:09:55 -0700 From: stevep at pcx.ncd.com (Steve Peters) Subject: Beer Marketing and "The Carbonator" In the last digest: >> term 'red' has been used a lot lately (Red Dog, Red Wolf, etc.) > >Funny you should mention those two.

(If given the choice between Coors >and Red Dog, I'll take the Dog.) I think there might be a smidgeon of very >light crystal malt in Red Dog and Red Wolf, and maybe people think they taste >a little like Red beers that are actually Red. After much thinking my homebrew buddies and I have figured out a way of understanding the marketing ploys of the majors: they have figured out that the majority of the beer drinking market has the following requirements from a malt beverage: 1) must be cheap 2) must not overtax the tounge (must not have any strong flavors which might offend) 3) must have an image to relate to (usually, party-boy, "bad" boy, rebel, wildman, strongman, attracts-sexually-aroused-women-man...) Also, to keep the drinking public's interest a new marketing gimic must be invented from time to time. Thus the procession from "dry" to "ice" to "red". It isn't important for these beers to taste any different, it's the label that counts. In fact, if you can think up a new three letter word they can hang a marketing campaign around, open an advertising company and start soaking in the cash. Probably actual "taste" and "flavor" is the least important factor after price and image. - ---- actual question! --- I bought one of those "carbonator" gadgets for pressurizing homebrew in 2-litre plastic soda bottles. I haven't used it yet, just emptied my first 2-litre o' Coca-Cola today. I'm wondering if I'll need a "Carbonator" for each 2-litre I want to fill with beer, or can I fill the bottle with beer, carbonate it, put on the old cap, and use the Carbonator on another bottle of beer? - -- Steve Peters Return to table of contents

Date: Fri, 15 Sep 1995 22:46:37 -0400 From: MrMike656 at aol.com Subject: Homebrewers in The Sun Had to set aside all the questions and comments I was going to post for this shocking story, which appeared in the September issue of the supermarket tabloid The Sun. The headline screams "HOME-BREW MANIAC ALMOST DROWNS IN HIS BEER". The story goes on to relate the tale of the poor stupid first-time homebrewer who "sampled too much of his own sauce and toppled headfirst into a vat of the product." His wife came home early from work after getting a phone call that their dog, Scruff was "barking alarmingly." ("What Scruffy? You mean you want us to follow you? Do I want a beer? Good dog!") She discovered her husband head first and unconscious in a (get this) 30 gallon (!) vat of beer he was supposed to be bottling. "I guess I was drinking one bottle for every bottle I was capping and got wasted," was his explanation. He says his days as a brewer are over. Ahem. I suppose we _should_ consider the source of this story. I didn't try calling the guy to confirm this (his name and town is printed in The Sun. Someone gave the article to me - I didn't buy it. And if you don't want to either, I suggest reading it while waiting on line at the food store.), but how many first time brewers brew with a 30 GALLON vat? But more importantly - is his beer ruined?

Date: Fri, 15 Sep 95 22:03 CDT From: pgravel at mcs.com (Philip Gravel) Subject: HCl/Coffee porter/Hops and head ===> Dave Bradley asks about HCl sources: > My questions: 1. Anyone know of a good place to buy food-grade > hydrochloric acid (dilute I'm sure)? I would like > to use this with my sparge water, but I need a > source, or at least some possible sources. I'm not sure hydrochloric acid is a good choice for controlling the pH of sparge water. It has no buffering capacity. If you want to use an acid rather than a mineral like gypsum, phosphoric acid (inorganic) or lactic acid (organic) would be better choices. ===> James S. Bayer asks about brewing a coffee porter: > I plan to brew a oatmeal/honey/coffee porter and am trying to decide when, >where and how to introduce the coffee. > >My options, as far as I can see, are: > >1.) Brew the coffee (strong-ish) and add to the boil. >2.) Add the grounds to the boil in a cheesecloth and steep (how long??) >3.) Dry hop with ground coffee >4.) Mash it with the grain. 5.) Brew a strong coffee and add it to the fermenter after you've cooled the wort to pitching temperature. You don't want to boil coffee. It ruins the taste. That's why drip brewed coffee has virtually replace coffee brewed by percolation. ===> Aaron Shaw asks about the effect of hops on the beer head > I also heard that dry hopping or using a hop-back will improve >the head retention of the finished beer. I checked the hop faq and >found no mention of this. Is it true? In my experience it is. I brewed a Sierra Nevada Pale Ale that used 3 oz of hops for dry hopping. The beer had the most incredible head I've ever seen. If I opened a bottle (not a geyser) and let it sit for a few minutes, a "snake" of foam would begin to rise out of the bottle. - -- Phil _____________________________________________________________ Philip Gravel Lisle, Illinois pgravel at mcs.com Return to table of contents
Date: Sat, 16 Sep 95 20:53:57 +1000 From: CHARLIE SCANDRETT <merino at ozemail.com.au> Subject: Getting Steamed Up Jim Busch writes, >It seems to me that you have designed a >wonderful, flexible brewery but cant be content with normal brewing processes >and want to emulate some giant brewer. There is basically no need for any of >this. <snip snip> He's right of course, but I'm interested why mega brewers spend millions on these systems when traditional techniques are simple and effective. Home brewers have many advantages, and we are slowly reverse engineering to home scale technology, copies of commercial brewing techniques where it has quality advantages. (Electronic mash control, counter pressure filling) I do need total sterilization for micro-brewed bottle-conditioned production. I do need to control melanoid reactions as I can't brew everything from English pale malt. I was only concerned if my proposed temperature regime would have negative effects on my traditional methods of DMS removal. (boil long-cool short) Sailors got by very well with wooden masts and sextants for centuries, now they are rare. Aluminium and sat nav has taken over. Brewing, like sailing, relies heavily on a lot of experience and a fair bit of intuition. With all my sailing and brewing gadgets, I'll never sail as well as Captain Cook and probably not brew as well as Jim Busch. However if I experiment and learn from homebrewers and megabrewers alike, my beer won't suffer for lack of understanding. . >If you have a steam boiler, steam heating is very gentle and will give >less caramelization than direct fired kettles. Steam is also very useful for transferring large ammounts of heat quickly. The lack of caramelization comes from no boundary layer on the kettle bottom to overheat. Stirring reduces caramelization. Kevin Mc Enhilt posts about steam infused mashing and Philip Gravel writes >Another problem is has to do with your assumption about how steam behaves >when it enters water. The steam bubbles will not remain as bubbles, but >rather will collapse almost immediately as the water vapor condenses into >liquid by the cooler water of the mash. Thus there will be little circul- >ation of water induced by the bubbling itself. There may be some due to >the thermal gradients where the just heated water due to steam injection >will tend to rise. He's right of course. Stirring worts during mashing is always useful, no matter what the heating technique. Also a pressure cooker can't give you the full advantages of steam without a header tank and it needs some valves, don't use the pressure release as an outlet! In step infusion mashing when you add quantities of boiling water, the temperature rise is quick, allowing precise rests to favour fermentability or body. The protein rest can also be skipped as per George Fix's suggested 40-60-70 mash for lagers. In decoction, the steps are similarily well defined except the thick part of the mash is removed and boiled, which aids gelatinization of starch. (bursting the cell walls) Nature is a bit of a bugger, putting the gelatinization point of starch above the optimum temperature for the enzyme conversion of it! Decoction's advantage is that the thin part of the wort contains most of the enzymes and the thick part most of the starch. This boil also seems to add flavour via caramelization and the gelatinized starch seems to convert differently and more completely. With steam, a 10 degree celsius step up in mash temperature can be achieved by adding 1.8 kilos of steam (1.8 litres water vapourizad) for every 100 litres wort. For a *infusion* of steam and a gentle temperature rise, you will need the appropriate ammount of water, a pressure cooker with standard release valve and a steam valve *pressure welded* into the lid, a steam coupling attached to steam hose (by your hose supplier who will pressure test it -- no simple hose clamps please!) You will also need a coupling welded onto a length of metal tube. This tube is shaped to reach the bottom of your mash tun and then coils around the bottom like an oppossum's prehensile tail. Block the end and perforate the coiled bit with a drill. This is you steam manifold. All the plumbing can be made safe by a pressure boilermaker. BTW fix the metal tube to the side of your mash tun, you don't want to be waving a steam wand around the room when the valve is opened. When you open the valve the head of steam will discharge very quickly and even if the water still in the pressure cooker is say 160C, only 9% of it will quickly convert to steam, reducing the temp in that cooker to 100C. Then you will have to add heat and even on the hottest stove, the output of steam is pretty slow. However the steam will enter the thick part of the wort and heat it first, aiding gelatinization and slowly raising the thin part's temperature by convection or gentle stirring, much like the effect of RIMS. With a steam setup, why use RIMS? On the other hand, if you use steam *injection*,(dumping a large head quickly in the thick mash) you can emulate decoction and step infusion. The catch is that there must be sufficient room for all the water to be steam at say 5 ATM. At 5 ATM the max steam temp is about 145C ( 418K). That doesn't matter much as the*latent heat of condensation* is what you are using to heat your mash. But Volume= (mass x temp(in Kelvin) x R (gas constant))/pressure. For steam R=0.231 For each kg steam (1 litre water vapourized) you will need (1kg x 418K x 0.231)/506 kPa = 190 litre tank rated to 5 ATM! That is serious scrounging! If this is infused quickly into the thick part of the mash it raises the temperature of that part above the gelatinization point of starch, the temperature gradient will spread the heat slowly by convection of quickly by stirring, protecting your enzymes in the thin part. Forget RIMS and decoction if you have steam, it does the same thing. It is similar to decoction mashing in gelatinization but not caramelization. The brewery builders we love to hate, Alfa Laval, decoct with steam and a partial vacuum. (for gelatinization, remember it is bursting the cell) If you have a diaphram pump and a sealable mash tun, try the steam injection when the tun is at 0.5 ATM, very dramatic! Instant low temperature boil of the thick mash, diffusing the temperature to the desired rest throughout the tun. Using steam *injection* you can jump to mashing rests very quickly, like "bucket o boiling water" step infusion, or slowly, or you can gelatinize like RIMS and decoction. The boiler can be just a pressure cooker, but finding a pressure tank about the size you need is the challange. They can be supprisingly cheap. If you want to go seriously to steam, email me. I will take the time to answer all you questions for safety's sake alone, I will enjoy it for beer's sake.

Date: Sat, 16 Sep 1995 10:40:06 -0400 From: kevinm at rocdec.roc.wayne.edu (Kevin McEnhill) Subject: Re: Mash Tun Percolator? / Steam pump In HBD #1833, you said; Darned if I could come up with a good explanation why the old "coffee pot percolator approach" isn't used in the mash tun (instead of stiring the mash). Someone jog my memory. Must be the temperature, which is sub-boiling. Or else the bottom-to-top temperature gradient is relatively small. But if temperature is the only reason for "why it won't self-percolate", then why couldn't you use a false bottom with a (sump) pump for manually recirculating wort? Why hastle with motors and belts and stainless steel paddles (that crash into your mash tun drain tubes)? Move the wort, not the grain. Well, That is the basic idea of what I was aiming for a few issues back when I sugested using steam to heat and move the wort. I think you can use steam bubbles in a tube like in under gravle filters in fish tanks. I was told by a couple of people that recirculating the wort was not nessisary for clear running wort, I wasn't even thinking about that (but now that you mention it ...), I was recirculating to maintain an even temperature in the grain. The thing that might have stabed me in the back was that the bubbles would colapse once the enter the 'cold' wort. Well I'm going to take the typical engineers approach and say "HOOWEY!" and try it any way (if you guys were closer, I'd bet some homebrew :-). ********************************************************************** * * /|~~~~~| I was told by my wife that * * kevinm at rocdec.roc.wayne.edu * | | | if I brew one more batch * * * | | | of beer she would leave me!* * Kevin McEnhill * \| | * * * |_____| I'm going to miss her :-) * ********************************************************************** Return to table of contents

Just to put a data point on the other end of the spectrum, I stumbled upon an extract Irish Stout 6-pack in the basement at Christmas 1993. I don't know exactly when I brewed this, but I think it must have been late '88/ early '89. You'd think stout would age the best, but ... blech. I think for periods up to a year things can improve (maybe longer for higher alconhol/certain ingredients), but much past that it would probably need refigeration (like Dean had) to give much chance for good results. E.g. it took over 8 months for a heavily ginger-spiked porter I made Feb '94 to hit its stride. This after I had to dump the first bottle I tried because it was too harsh (one month in bottle). But the small amount I held onto until early this summer was definitely beyond its peak (I did not refrigerate). Still great to boil hot italian sausage with though :) Return to table of contents

Anyone >have any thoughts on this? I doubt it would work on my electric stove, and even if it did, it would probably destroy the stove eventually. I am already experiencing staining and heat discoloration from using a 5 gal pot (16 batches). In an effort to reduce stove damage, and also to lesson wort darkening resulting from direct pot contact with the burner, I made a trivet from coat hanger. Result was the wort wouldn't boil any more. This was with 3 to 3.5 gal wort. My last stove batch is this weekend; getting a 10 gal pot and propane setup next week. The stove and my SO are both very happy, and I get to introduce the neighbors to the smell of boiling wort :-) My suggestion is to look into propane setups. -Tim timf at relay.com "Beers me" Return to table of contents

The general concensus was NO! However, in the July\August issue of Brewing Techniques (pg 22) the following statement was made: "When using Irish Moss, it is important to rehydrate the material before adding it to the kettle. For a 10 gallon batch, combine 1 tbsp Irish Moss with water and let stand overnight or for several hours. Add it at knockout or within 15 minutes of knockout." Is this news to the entire collective since so many replied to my previous post that they had never heard of rehydrating IM? Advantages/disadvantages? Also, what is the "Knockout?"

Date: Sun, 17 Sep 1995 08:49:17 +1000 From: david.draper at mq.edu.au (Dave Draper) Subject: Coffee brewing Dear Friends, re: the recent posts about using coffee in dark beers (and others too!). I've used coffee in one of my stout recipes lots of times and have really enjoyed it. However, my taste is for a much more subtle effect. I don't want the taster to say "Wow--coffee" immediately upon drinking it, but only to notice a new and different flavor that helps the others marry more effectively. I've done two things: 1. Add some grounds to the last 5 or 10 min. of the boil; 2. Pour brewed, cooled coffee into the primary at pitching time. Both work well and give the desired effect, and in my experience do nothing to damage heading. Amounts: about 2 tablespoons or so ground coffee (use the good stuff) or one large mug of quite strong brewed coffee. This gives a flavor that, for my tasters at least, is not immediately recognizable, but once you tell them it's coffee they have no trouble picking it out. BTW I have only ever used Wyeast 1084 Irish on these beers; I don't have any info on how different strains might make use of the coffee notes.

In regards to chocolate part of the post, here is our recipe for our 1st attempt at brewing with chocolate. Sorta bastardized Papazian. In my opinion, it was a little too malty, maybe cut the Dark DME down to 1/2 - 1 lb. Also, the chocolate left a white film (cocoa butter?) around the edges of the carboys (1st and 2nd) and even in the bottle. I'm pretty sure that it wasn't bacterial, but it was a PIA to remove. Anyway, it was very chocolatey (not sweet, but bitter) and rich, more like a stout, also I think (the chocolate?) was the cause of mild headaches for me (noone else seemed to get them though) Definitely a beer worth altering / repeating and I'm not even a big fan of chocolate anything. Nate P.S. I don't yet have the guts for an "espresso" stout, kinda gives new meaning to "Beer isn't just for breakfast anymore" though! :-] Willy Wonka Porter (chocolate) 5 Gallons 6.6 lbs Amber Extract (Ireks Bavarian, I think) O.G 1.065 1 1/2 lbs Dark Dry Extract F.G 1.022 1/2 lb Chocolate malt 1/2 lb Crystal 1/4 lb Black Patent Malt 3/4 lb Unsweetened Bakers Chocolate [Hershey's] 8 oz Malto Dextrin 2 oz Northern Brewer (pellets) 6.9% AAU 1/2 oz Cascade 4.9% AAU WYeast # 1056 Steep grains in 2 gallons of 150 F water.

I received no confirming reply (via e mail!). I called (with my own dime) them on Thursday, 9/7. They said it was shipped on Wednesday 9/6. I finally received the package on Thursday 9/14 (a week later). It was shipped UPS second day air. I went to UPS tracking on WWW. They had not shipped the package until 9/12. Obviously they had lied (intentional or not) to me when I questioned them on the phone. They told me they were very busy. Sorry but this is not an excuse. I know how I'll solve this problem.

I've been buying Muntons' Light Malt Extract in the 15 kg plastic/vinyl jugs for a couple of months. Last Sat I opened a new one and used about 10 or 12 lbs. This morning, while I was looking for the lysol uder our kitchen sink, I noticed that the jug was A WHOLE LOT ROUNDER. When I opened it it smelled of fermentation and had about 1/2 to 1 inch of bubbles on top of the remaining 20 lbs of malt extract. Having squashed the jug back into a more cubic configuration, I'm planning to check it regularly to avoid malt armagedon. My questions: 1. I assume the stuff is still usable given the small amount of O2 in the jug. Am I right? 2. Should I only brew reds, darks & large brews with it, or is a pilsner still a potable possiblity? 3. Is there some precaution I should be taking to avoid contamination, or was this more likely a bug aleady in the stuff that was activated by the O2 when the jug was opened [now that I think back, there were a few foamy bubbles in the stuff when I bought it]? TIA for any thoughts via private email, or if folks think this kind of thing is aa matter of general interest, via general post. Jim Return to table of contents

My last >batch was 5 gallons with 5 lbs light extract and 1.5 lbs honey. Color? >Yup.....amber. I've found it about impossible to brew a light colored beer with extract. The fact I do partial boils (boiling maybe 3 gal wort, then adding water in the primary to top up to 5 gal) makes matters worse because concentrated worts tend to darken/caramelize more. I assume you are in the same boat. To product a lighter beer, I've found it helpful to increase the amount of grain and decrease the amount of extract accordingly - partial mash. The last beer I made (an IPA) was the lightest I've done. it used 6 lb brit 2-row pale malt, 1/5 lb crystal, and 3 lb extra pale M&F DME. OG 1060. Note the EXTRA pale DME.

I have been using an aquarium pump/airstone setup for a long time to aerate my wort. The stone is direct from my local pet store (don't remember what I paid for it, but it wasn't much) and I sterilize it by boiling (yes boiling!!). This doesn't seem to hurt it in any way. I attach the stone to the end of a straight racking rod which goes thru an orange carboy cap. On top of the cap I have a homemade filter which uses sterile cotton balls as the filtering material. I sanitize the racking rod, carboy cap, and filter housing in bleach. My hose from air pump to filter housing is -not- sanitized. It's very small diameter hose which would be very difficult to dry. I have yet to have any infection attributable to this setup. ================================================================== Dan McConnell writes: > I urge everyone to think like a probrewer, not a homebrewer. > REPITCH! That's what the professional brewers do, amateurs > should too. I'll get to that in a minute. Very good advise, BUT...... I'm finishing up on a Pale Ale and I want to brew a Pilsner next. What do I do?? Use my Ale yeast dregs to brew the Pilsner. Not! That's the big difference between the professional brewers and us professional homebrewers. The other guys put the same brew out the door day after day, THAT'S why they can (and do) reuse their yeast. I brew a different brew every time so I guess I'll just have to start a new yeast every time also... ************************************************************ Doug Flagg | "A Homebrew a day... dflagg at orono.sdi.agate.net | Keeps the Worries away!" ************************************************************ Return to table of contents
