Date: Tue, 1 Dec 92 14:55:56 +0100 From: Alan B. Carlson <alanc at cs.chalmers.se> Subject: Weird Yeast Starter I started a yeast culture the other day. Took the dregs of two bottles of homebrew from a batch of beer that was brewed with first generation Wyeast Bohemian pilsener. The "wort" I used was a approximately a pint of water and a little less than a half a pound of granulated sugar that was boiled for 5 minutes. When it cooled I threw in a teaspoon of yeast nutrient as well. The day after the starter was starting to bubble, I noticed some almost clear agglomerations floating at the top of the wort. Some of the same stuff was in suspension as well as lying on the bottom. The stuff reminded me of the meat of a lemon (you know, floating around in ice tea) although it is absolutely colorless. The gas emanating from the airlock smelled like yeast. Yesterday, I threw the stuff out since I didn't want to waste a batch of beer not knowing whether it was an infection or not. Before chucking the stuff into the sink, I poured the starter into a glass. The agglomerations that were present before dissolved completely. Not a trace of them in the glass. Can a starter look like this without being infected? Can it be some sort of bacterial contamination or or can it be the yeast nutrient? I've never seen a bacterial infection before so I have no idea what one looks like. The brew that I cultivated the starter from was the first batch I've done with liquid yeast and the starter I used then sure didn't look like this last one.

The ad claims (and i agree) that glass is easier to clean than plastic so you don't need to do as much work to get all the gunk out. I currently use a 1" i.d. tube that works really well but is a total bitch to clean, especially after a particularly violent batch.

Date: 1 Dec 1992 09:33:40 -0500 From: "Daniel F McConnell" <Daniel.F.McConnell at med.umich.edu> Subject: Bees and Boston Subject: Time:9:30 AM OFFICE MEMO Bees and Boston Date:12/1/92 Bob Jones writes: >I have noticed that bees seem to find their way into my garage when I brew. >I especially notice them after the wort is boiling. Anyone else notice this? Yes, I've had bee problems during the summer, but I notice it mostly when mashing and sparging, attracted by the sugars. A few have been lost in the boil (worker bee ale?) and fished out. I have also noticed that when the sky becomes overcast the bees go away. I've never been stung though, so I assume that they approve of my efforts. Try making perry in the fall if you are thrilled by the prospect of happy bees crawling on you (just don't let them down your shirt collar or up your pant leg). On another note- I am flying to Boston this weekend. I'm not sure where I will be staying-somewhere near Harvard/Mass. Gen. Hosp., I assume. What are the beer-highlights of the area, assuming that I can escape for some free time? I have been to Commonwealth and will try to return. Are there any other (or new) brewpubs within subway distance? Any interesting (rare) imports that are not available elsewere (Michigan)? Thanks for the help. DanM Return to table of contents
Date: Tue, 1 Dec 1992 09:43 EST From: GREG PYLE <S1400067 at NICKEL.LAURENTIAN.CA> Subject: Carbonating Mead Hello, I have just brewed my first batch of mead. So far, I have racked it twice. I know that traditional mead is uncarbonated, however, I thought that carbonating it might be a nice touch. I got to thinking that if the yeast is all dead (and assumably it is, since the alcoholic content is in the order of 12-13%) and all of the suspended yeast has settled out, how will the mead carbonate if I simply prime with corn sugar at bottling time? My questions are as follows: 1) Should I carbonate the mead and if so how? 2) Does all of the yeast settle out? What happens in the carboy? 3) Is the alcoholic strength of the mead too strong to support any yeast activities? Thank you, Greg. Laurentian University Sudbury, Ontario Return to table of contents

About $60 (Granger). It works well for transfer of hot sparge water. I'm a little concerned about transfer of cold wort to fermentation vessels, unless you knock the thing down and sanitize the impeller assembly. The only problem that I have encountered is that it does not pump boiling water well. It tends to form an airlock above 95C even when well primed. I'm also happier transfering hot wort by gravity because the impeller seems rather abusive. Return to table of contents

Date: Tue, 1 Dec 1992 10:18 EST From: STROUD <STROUD%GAIA at leia.polaroid.com> Subject: Baderbrau stock James P. Buchman asks about buying shares of Baderbrau. There was some chatter about it on Compuserve a few months ago. It is (or at least was) on NASDAQ under BRAU. Art Steinmetz did some digging around about Baderbrau's financial situation and posted the following: ********************* From: Art Steinmetz/NYC 76044,3204 I just pulled up some stats on BRAU on my handy-dandy screen. Pavichevich Brewing has yet to make a profit. The stock has been trading, I think, since 10/89 although the company has financial results going back to 1987. The stock price ran up to 6-1/4 in 4/90 and promptly crashed to 1-1/2 by the following Jan. It's quoted between 2-1/2 and 2-3/4 for the last year. Price action is non-existant. Volume is invisible. 1.56mm shares outstanding. In October 1990 they defaulted on bonds they issued and owe $250k in back interest on those. They owe $1.25mm to Steel City National Bank of Chicago. As of this Jan. they were in a capital crisis since operating revenue was insufficient to meet operating needs. They were trying to arrange $1.5mm through a sale-leasback of the equipment. Didn't happen. Around June they raised $426,000 in a private placement of stock. They're still up to their eyeballs in debt. Total liabilities are $2.3mm vs. assets of $2.7mm as of 1992Q1. They must have some more debt somewhere 'cuz my screen shows a negative book value for the stock of $-0.20 per share. Sales in the quarter ending April 30 were $227,000 vs. $237,000 previously. Beer unit sales were up 6% but prices declined pursuant to their distribution deal resulting in the drop in revenues. Paterno Imports Ltd. has been their national distributor since June 1991. They're hanging on by a thread. Caveat Emptor. ********************** I'll bet that a lot of US micros are in similar shape........ - --Steve Return to table of contents

Date: Tue, 1 Dec 1992 07:57:37 -0800 (PST) From: Paul dArmond <paulf at henson.cc.wwu.edu> Subject: Removing Chlorine My brewing water comes off a private water association. I went in to the county health department to get a water analysis, just out of curiosity. The analysis was just puzzling, all of the substances tested for were low, but the total dissolved solids was 450 ppm! No idea what the unknown goobers in the water are, but the district is out of compliance... Anyway, I'm talking with my friend who works there and telling her about my homebrewing... I ask her about the chlorine levels, since I know the water association has been docked for not controlling it properly. I've been concerned about getting the chlorine out of my mash and sparge water, so I've been boiling it beforehand. She tells me that boiling only removes chlorination by pure chlorine gas! Our water association uses sodium hypochlorite (bleach). This is not removed by boiling. She says that hypochlorite can be removed by two methods: exposure to sunlight and evaporation, and adding sodium thiosulphate (photographic hypo). Setting my water out for a couple of days is not real practical (among other things, I live in NW Washington state, so we won't see any UV for another seven or eight months...), and I don't really want to add hypo to my beer. Ick! The other thing that I learned is that there are three ways to chlorinate water: gaseous chlorine, sodium hypochlorite, and chloramine (sp?). I don't know anything about chloramine, but my friend tells me that it is a more stable form of chlorine compound. She also tells me that < 4ppm chlorine has little or no purifying effect, and > 8ppm is too much and will taste of chlorine. Supposedly, if it is done right, you can't taste the chlorine... We always have a strong taste of chlorine in the water and 2 out of 3 beer judges tell me I have phenols in my beer (sob...) Does anybody know: 1) What are the reaction products of sodium hypochlorite and sodium thiosulphate, and is this safe in beer? (I suspect not...) 2) What will remove the chlorine from my water? Thankz, Paul. Return to table of contents

I also had a diacetyl problem. I believe Miller advocates doing the diacetyl rest in the primary after fermentation subsides. Something to do with the lack of oxygen causing the yeast to absorb the diacetyl (speeded up with a temperature boost). If you rack to the secondary before the diacetyl rest, then some oxygen will be introduced and prevent the absorption of the diacetyl. My current fermentation schedule is (for ales): 1) 3 day primary fermentation at 65F. 2) 2 day diacetyl rest at 70F in the primary. 3) 7 to 21 days in secondary (in the coldest part of the house) for clearing & dry hopping. I haven't tasted any of the batches since switching to this schedule, but I'm hoping that this schedule solves my diacetyl problem. I did notice the strong butter-scotch odor eminating from the air lock disappear during the diacetyl rest period. Christopher Lyons LYONS at ADC3.ADC.RAY.COM Return to table of contents
Date: Tue, 1 Dec 92 12:10:13 EST From: dipalma at banshee.sw.stratus.com (James Dipalma) Subject: RE: Wyeast 2112, counter pressure bottling Hi All, In HBD 1023, Rob Bradley asks: >I'm planning an Anchor Steam clone. I welcome any hopping suggestions >that have been tested, including unconventional ones. Quite some time ago, someone posted to HBD describing a tour they had taken of the Anchor brewery in San Francisco. This post went into such detail that it sounded like a report from an industrial espionage mission. The poster reported that Anchor uses Northern Brewer for bittering and Hersbrucker for aroma. According to Fred Eckhardt, the bittering level is 40 IBUs. Anchor Steam(tm) :-) also has a considerable hop nose to it, so dry-hopping is indicated. Rob also asks: >Has anyone else had the same problems Murray Robinson experienced with >WYeast 2112? Maybe I'll have to change my weekend brewing plans :-( Re-reading Murray's post(HBD 1022), my interpretation is that he was using liquid yeast for the first time, and was concerned that the *starter* was not showing much of a krausen. Murray didn't specify the gravity of his starter, but my understanding is that starters with a gravity of 1.020-1.025 won't display much of a krausen. I've used liquid yeast exclusively for the past year or so, with starters of that gravity, and have never gotten the large krausen one normally associates with primary fermentation. At most, I see a small ring of bubbles around the edge of the liquid, and some bubbles coming up through the solution, yet I've always gotten good vigorous fermentations using these starters. Coincidentally, I used Wyeast 2112 to brew an Anchor Steam(tm) clone this weekend. The temperature in my basement is 58-60, I pitched the yeast mid-afternoon, when I checked it just before bedtime there was foam forming on top and bubbles in the airlock. Looks good so far, so my advice to Murray and Rob is to relax. Also in HBD 1023, an interesting discussion between Al and Jack on counter-pressure bottling and carbonation. Until recently, I was one of those people who bottled from the keg without a counter pressure bottle filler. Several HBDs ago, I posted a procedure for doing that which involved chilling the bottles and filling right to the top. These steps are an attempt to minimize the CO2 passing out of solution due to the pressure drop that occurs when the beer comes out of the tap. A few weeks ago, I obtained a counter pressure filler, and I've noticed the same phenomena that Jack reported. Beers bottled with the counter pressure filler are much better carbonated than those bottled straight from the tap. I agree with Al's conclusion that counter pressure fillers minimize the loss of CO2 by keeping the beer under pressure during the whole transfer process. Another advantage of the counter pressure fillers is that the bottle can be purged of oxygen prior to filling. When bottling straight from the tap, the presence of oxygen in the bottle assures some amount of oxidation will occur, regardless of how quietly the bottle is filled. If the beer is going to be consumed within a short period of time, this may not be significant. However, if the beer is to be kept for several weeks, or submitted to a competition, I`d recommend a counter pressure filler. One more anecdotal point about the filling straight from the tap method, it's not exactly foolproof. Some months ago, I went to a friend's house to help him bottle some beer from his keg. He had used forced carbonation, and had gone a little overboard, as he kept the beer under 40 psi at 40F. The beer was so highly carbonated, it foamed violently as soon as it hit the end of the tap, making it impossible to fill a bottle. After about 30 minutes of trying, all we had achieved was an incredible mess, one-half gallon of homebrew sitting in a catch basin, another half-gallon sprayed about his cellar floor, six bottles half-filled with foam, and two very chagrined homebrewers.

I suggested that he may want to enter his beer in a competition. Then it dawned on me that I haven't noticed competition information in the Digest. I don't (yet) subscribe to Zymurgy, but I'm sure others out there do. I know, for instance, that the St. Louis Brews club is having a competition in December.

Date: Tue, 1 Dec 92 13:02:17 EST From: Andrius Tamulis <ATAMULIS at ucs.indiana.edu> Subject: Plastic boilers In regard to Jeff's idea to install a heating element in a plastic bucket and use that to mash/sparge/boil. Well, I've got experience here. I've done just that. Twice. My suggestion is not to do it. I did this for mashing - nowhere near enough heat was produced for boiling. (I boil on a stovetop, and even wimpy stoves put out more heat than the element ever did) My experience with mashing in it was bad - the mash was too hot near the element and too cold away from it, stir as I might. Both of these Bruheat clones have been relegated to sparging duties, and I now do the mash and boil on the stovetop. As far as structural integrity, I made these 2-3 years ago and just recently one sprang a leak around the spigot. No worries there! In sum, I advise against. andrius Return to table of contents
Date: Tue, 1 Dec 92 09:30 CST From: arf at ddsw1.mcs.com (Jack Schmidling) Subject: Mash Thickness To: Homebrew Digest Fm: Jack Schmidling After reading an interesting article on barleywine by Micah in the current issue of the Celebrator, I bagan to wonder about the reasons for thick mashes. He recommends using a megadose of malt in a mash of about normal consistancy, to produce a high gravity wort without sparging. George Fix has also written about the advantages of minimal sparging. So I ask, why do we sparge at all? Why not just mash 10 lbs of malt in 10 gallons of water, drain it off and start boiling? The search through my references was not very satisfying on the subject. It seems that the most repeated reason is that the enzyme efficiency is reduced. But like so many other "problems" that claim this as the evil, the solution is to simply mash a little longer or use more malt. Noonan goes one step further and says a "thick mash improves enzyme performance. In a thin mash, proteolytic and other heat-labile enzymes are destroyed in the course of the rest: in a thick mash, they may survive into the saccharification range." This makes no sense at all. It reads more like a description of the survival rate of wildebeasts as a result of herding than of chemestry. Can anyone support this legend with actual experience? Sparging is a "simple" and efficient way of extracting the sugar from the grain but all other things being equal, it would be more conveninent to use a thin mash and just a small final sparge to rinse out anything left behind. It would also greatly simplify that first plunge into all grain beer. js Return to table of contents
Date: Tue, 1 Dec 92 13:42:32 -0500 From: bradley at adx.adelphi.edu (Rob Bradley) Subject: SN clone recipes, fruitiness revisited I posted in HBD 1021 about my Sierra Nevada clones and asked questions about fruitiness. Some people have asked for recipes: Pale Ale Porter -------- ------ 7 lb 7 lb UK 2-row pale ale malt (Munton & Fison) 1 lb 1/2 lb UK 2-row crystal malt ("Wine Inc." brand; Lovibond=?) ---- 1/2 lb UK 2-row chocolate malt ("Wine Inc.") 1 3/4 oz 1 oz Cascade flowers, 1 hour boil (all hops 5.5% alpha) 1 oz 1/2 oz Cascade flowers, 30 minute boil 1/2 oz 1/2 oz Cascade flowers, 15 minute boil 1/3 oz 1/2 oz Cascade flowers, add after boil & steep 15 minutes 1/5 oz 1/5 oz Cascade flowers, dry hops Wyeast 1056 for both 1048 1050 Original gravity 1012 1014 Final gravity Day 6 Day 6 Rack to secondary No fining Day 7 Gelatine finings Day 6 Day 8 Add dry hops Day 12 Day 18 Bottle Infusion mash: Strike with 2 gallons at 167F Hold at 150F for 75 minutes Mash-out at 172F. Sparge with 4 gallons at 172F. Brew length was slightly more than 5 gallons. Exactly 5 gallons racked to secondary. What I would change: For the porter, nothing :-) For the pale ale, I would use Perle (as SN does) in the first hop addition and fewer HBUs of it. 1 ounce of Perle at 7.6% was suggested by Brian Batke. He also suggested Perle for the 30 minute addition. Other notes: I like the effect of a 15 minute steep after the boil; some might worry about DMS. Some would think 5 grams of dry hops insufficient; perhaps I would use more if I didn't have the steeping hops. The slightly higher yield from the same weight of grist in the porter may be explained by a different grain bag (you may recall I lost my Brew-bits bag)-: Tony Babinec suggests that an all-Cascade pale ale of this sort is more in the style of Liberty Ale. I agree, but I would add even more boiling hops and finishing hops if I were trying to clone it. Some have suggested that SN is not very fruity beer. I agree. The fruitiness I was referring to was subtle. The beer in question was about 60F. I had another SNPA this weekend. It had been in the fridge and then left at room temp for 30 minutes (so <50F?) and at that temperature, there was no evident fruitiness. Plenty of hop aroma and maltiness, though. Finally, I said in 1021 "Ultimately, fuitiness derives from the malt", or words to that effect, your honor. By this, I never meant to downplay the importance of yeast and temperature in ester production. However, the chemical constituents of the esters don't fall from the heavens, they come from the malt. I was only wondering if what effect, if any, the malt might have on ester production. Cheers, Rob (bradley at adx.adelphi) Return to table of contents

Date: Tue, 1 Dec 92 13:08:38 PST From: "Bob Jones" <bjones at novax.llnl.gov> Subject: Mashing & sparging from Micah Millspaw Mashing/sparging problems? >Causes I can think of are: >1) strike temp was not high enough to gelatinize the starch If this was actually the temp it should not be a problem, I've seen my highest yeilds from lower temp mashes 148-50 F. >2) the crush was actually too coarse (I WANT a roller-mill!!!! Santa???) This is problably less than ideal but is not as likely a culprit as would be a too fine crush. >3) I should indeed have done a step-mash and raise the temp to 158 for 15 min. at the end of the mash. Yes, a mash out should help because it tends to get more sugars in solution which makes for more effective sparging. I think that the mashing end of grain brewing is less of a problem than the sparging side, but it gets the blame anyhow. >4) I sparges too fast. This is possible but not usually a physical possibility. >5) the mash was too tight. Miller recommends 1.33 quarts per pound. > This was indeed the tightest mash I have yet done (Micah??? you say > you usually use a rather tight mash.....) What I consider a tight mash is 24oz water /pound grain and not to excede 32oz/lb in a normal mash. The stiffer the mash (with in reason), better the more effective the enzyme activity. This also allows for more water to be slated for use in the mash out and sparge without add to the total amount of water used. I would consider 1.3 qt/lb to be a very loose mash. >6) As I said, this same sparging system has turned out 29-30 points, so I > am pretty confident that I am not suffering from dead spots in the > lauter-tun. I would not change this system then, but I would look at changing the allocation of your mashing/sparging water. micah >Put the wine (or dopple-bock!) into a shallow vessel and cool to 32F. >Place ice cubes into it and drop the temp below freezing.

I would just like to point out that any atempt to concentrate alcohol by any means, including freezing is not legal in the USA. And that regardless of the volumes involved, it carries the same property forfiture and penalties as the manufacture of illegal drugs. So be careful with this topic.

This would be similar to the If you have a plastic container that will stay structurally sound at the proper boiling temperature (a little above the boiling point of water because of disolved materials), you will have to be sure that the element cannot come too close to the plastic. |A quick experiment in which I filled my bucket with a couple of |gallons of boiling water resulted in a slight softening of the |plastic, but there were no alarming structural problems. I would consider a slight softening with water that has started to cool down from boiling as an alarming structural problem. 1. The temperature durring the boil will be a little higher. 2. A full batch will exert more force on the plastic than a couple of gallons. 3. The boiling time is probably longer than your test. If you are still intent on trying it, I'd suggest a test run using the more water than you intend, adding salt to bring up the specific gravity of the water above what you normally use, and boiling for about twice as long. Maybe doing this whole test in a bath or wash tub and watching it the whole time would give you some confidence.

Date: 1 Dec 92 10:35:00 PST From: John Fitzgerald <johnf at ccgate.SanDiegoCA.NCR.COM> Subject: leaving the trub in your wort I know this has been covered before - about how the trub contains valuable food for the yeast - but I ususally ignored the issue because I wanted to get as much junk out of my beer as possible. So I usually siphon the cooled wort from the brew pot to the primary, leaving the slimy stuff behind. But this last batch I did something a little different. I pitched the clear wort in primary with an 8 oz. starter of Wyeast European Ale (1338) that was at full krausen. I then took the muddy layer of trub, including lots of hops residue (from pellets), and transferred it into a sterlized 2 litre soda-pop bottle. I had about 1/2 gallon of mud. I added a few drops (8-10) of yeast that was left in the starter bottle, and placed the muddy concoction under fermentation lock. Ten hours later very differnt things were happening in the 2 'batches'. The muddy half-gallon had separated into 1/3 sediment, 2/3 fermenting beer. The 5 gallons in primary hadn't done anything. The yeast came from the same source, the wort came from the same source, the temps were all the same, the only difference appears to be the trub contained in the half-gallon batch. I didn't try to estimate the volumn of the 'few drops' of yeast, but it seems that 8 oz in 5 gallons is a better ratio than 'few drops' in half-gallon. My last experience with batch 1338 took 24 hours to show signs of fermentation, but that was siphoned off the trub also. I ended up siphoning the active wort off of the sediment, and into the non-active batch, and sometime during the night the 5 gallon batch took off. I'm not saying that this proves anything, but since I do 2-stage fermentation anyways, I'm thinking of leaving any cold-break material, hop residue, etc. all in primary and then siphoning off of it when going to secondary. I figure I will be at higher risk for producing chill haze, but it might be worth it. Any comments/advice would be appreciated. John Fitzgerald Return to table of contents
Date: Tue, 1 Dec 92 16:18 CST From: akcs.chrisc at vpnet.chi.il.us (chris campanelli) Subject: Brew Bees Bob Jones brought up an interesting observation in regards to bees and garage brewing. I too brew in the garage, not out of choice but because of a fascist, anti-brewing female thing. Well, that and maybe the Wave of Wort debacle, but I'm sure its mostly the female thing. I have bees visit when I brew. A lone bee will show up around mid-mash, soon to be followed by its friends. By end of boil the bees number about a dozen. They appear to like the wort and things that come into contact with it. The stirring spoon, thermometer and spent ph strips all get surreptitious inspections. When wort drips on the floor, the bees fasten around the droplets like spokes on a wheel. I assume its the malt sugar they're after. At first I thought having bees around while brewing was a bad thing, what with sanitation and all that. I went so far as to try to rid the garage of bees via a badminton racket. It became a war of diminishing return and I soon gave up. Although the bees never noticed me running around in circles swinging a badminton racket, the neighbors sure did. I once asked an entomologist friend about bees and brewing. He went on and on about nectar, chemical receptors, wind direction, sun elevation, hive dancing and food stores. All well and good I guess. The next-door neighbor's ten year-old explained it differently. She said that bees like sweet stuff. And they say the smart ones have college degrees. I no longer mind having bees around when I brew. We both go about our own business. I'm careful not to step on them, I politely shake them off the utensils and I keep my pint covered with a coaster. In return they've never stung me and they've never once asked for free beer. Not yet anyway. chris campanelli Return to table of contents

I ask because space is tight at the homestead and I think this is the only way my wife will agree to a second frige in the house. I think the only cooling element would be the freezer at the top of the unit. I think I might have to cut out a small bit of one of the door shelves to fit a plastic 7.5 gal fermentor in there.

Date: Tue, 1 Dec 92 18:26:42 -0800 From: kensiski at nas.nasa.gov (David L. Kensiski) Subject: can I rescue this batch? A colleague and I have brewed a lager pilsner that suffers from a lack of carbonation. It tastes really great for about the first 10 seconds after you open it, then it goes flat. We have been experimenting with the amount of priming sugar in the batch; that's the likely culprit. We brewed it way back in September, then fermented it for 6 weeks. The SG went from 1.042 down to 1.007, so the yeasties seem to have done their work. We then primed with 2/3 cup of corn sugar and bottled it. It's been in the bottles now for about 6 weeks. But I'd like to try to rescue the batch. Can I just open each bottle and add a tad more sugar solution? If so, how do I determine how much and at what concentration? Should I add more yeast as well? Any advice would be appreciated. Thanks. - --Dave ________________________________________________________________________ David L.

Date: Wed, 2 Dec 1992 15:55:39 +1030 From: Murray Robinson <robinm at mrd.dsto.gov.au> Subject: WYEAST 2112 - Problems Solved Thanks to everyone concerned with regards to the apparent problems I had had with WYEAST 2112 - California Lager. What has become perfectly clear is that when using a liquid yeast you must allow the yeast to reproduce to the maximum extent in the original packet if you wish to avoid lag times in the starter culture and finally the fermenter. I must admit that I probably pitched my yeast into a starter for two reasons: 1) I had a new toy that I was itching to use and so probably pitched it a little early. 2) Autralians work in metric units not imperial so a 1 inch thick yeast packet is and arbitary measure of thickness to me. Premature pitching of the yeast from packet to starter IMHO obviously results in significant lag times (in my case more than 48 hours) which then exposes the starter to potential spoiling by harmfull bacteria. Fortunately, my Munich Lager is now fermenting away furiously in the fermenter with no off smells or flavours. thanks again, MC Return to table of contents
