---------------------------------------------------------------------- Date: Wed, 17 Mar 93 16:42:36 -0500 From: Timothy J. Dalton <dalton at mtl.mit.edu> Subject: sterilization, aeration, filtration. I've been reading an intersting book the last week: The Biotechnology of Malting and Brewing, by J.S. Hough (Cambridge Univ Press, 1985) Anyway, while reading it, i've run across a few things that answer recent threads on r.c.b and in HBD All are quoted without permission. Steam Sterilization: (p.49) "Steam is also use for sterilisation but can only be fully effective if it is saturated and operates in hot equipment. There must be ample oppotunity for the condensate to escape as the equipment heats up. At least 30 min steam treatment at 1 bar over pressure after the equipment has heated to 100C is necessary to achieve sterilisation of a cleaned piece of equipment." Wort Aeration: (p. 91) "Aeration of wort is needed for yeast growth. Specifically it is required in small amounts (5-15 mg/l) by the cells in order to synthesise unsaturafed fatty acids and sterols for intracellular membranes...Air will provide a maximum of 8 mg/l dissolved oxygen. Some strains of yeast however require more than this and oxygen is substituted for air." Yeast Size: (p. 96) "A typical brewing yeast cell will, when fully grown, be between 8 and 14 um diameter and have a mass of about 40 pg when dry. Thus, 10^12 dried cells will weigh 40 g." Control of Infections: (P. 111) in austenitic stainless steel vessels, "The sequence is wash thoroughly by water, using high pressure revolving jets or static spray balls in the vessels. When the water has drained, hot caustic soda (usually with some sodium hypochlorite) is used as a detergent-sanitizer. The caustic soda kills microbes effectively and is an excellent dissolver of protein. It is not however suitable for dissolving and keeping in suspension calcium salts, therefor additions of various polyphosphates, metasilicates or guconates may be made. The hypochlorite is a source of free chlorine and therefore a strong bacteriocide; it also enhances the cleaning power of the detergent. Free chlorine is however a dangerous agent of corrosion of stainless steel if the pH of the solution falls to neutrality or below." Filtration: (Pg. 143-147) Several filtration techniques are talked about. Its too long to post. Bottom line is that diatomaceous earth (kieselguhr) is the most popular filter type. This, in combination with a secondary membrane filtration does a great job. 1.0 um membranes will be expected to prevent yeasts from be penetrating, and a 0.2 um membrane would be expected to hold back bacteria.

I have a couple of small paperbacks on the subject, but would like to know if there is one or two good sources for us novices? I have yet to brew my first batch, but I am getting anxious to start. Any info that you longtime brewers can impart to a beginner would be greatly appreciated. I just moved to Big Rapids, MI and don't know where I could get brewing supplies. Is mail order the answer?

Date: Wed, 17 Mar 1993 14:20:28 -0800 (PST) From: Peter Maxwell <peterm at aoraki.dtc.hp.com> Subject: crystal malt in muslin bag In HBD 1099 Mike Rego asks about Cara-pils haze. This prompts me to ask a more general question regarding the addition of other malts to an all-extract brew. Up until now I've been putting these in a tighly-woven hop bag, but am convinced that the bag is too small, packing all the grains in much too closely and restricting the extraction I get. I'm thinking of using a much larger bag made out of muslin, but am wondering if the much coarser weave will allow undesirable things into the wort. My procedure is generally to steep the grains for 20 minutes or so at 170 degrees, then remove the bag prior to bringing the wort to the boil. The grain crushing process (either a rolling pin for me, or sometimes I buy it pre-crushed from my brew shop) produces powder along with broken grains. How important is it to sift all this powder out? If it gets into the wort will it cause any problems? My thoughts are that the muslin idea would work, because in full grain brewing all this stuff is thrown in with no strainer bag, right? Any comments/suggestions are most welcome.

(I used it to > give it a little more body, but have since learned that it is not > like other specialty grains.) Here are some answers (even to questions you didn't ask): the amber color is not surprising, really. You'll find that one company's "light" is another's "amber" and that truly pale beers are tough to make from extracts. In part, this is because the evaporation process necessary to create syrup from wort often is allowed to darken the product. But the German syrups are particularly dark, or they were several years ago when I did an experiment for Zymurgy and compared a dozen brands of extract. Carapils does not cause haze, although there seems to be an odd train of thought out there to this effect. On the other hand, regardless of what Charlie Papazian says, you shouldn't be boiling your specialty grains. Far better to get them out earlier, and even better to simply steep them at about 150F for an hour or so, then rinse them and use the resulting liquid along with your extract. Carapils will give your beer more body if it's properly used; I can't imagine what "not like other specialty grains" means in this context, but it sounds as though someone was giving it a bum rap. Carapils also has the added benefit of enhancing the "maltiness" of beer, which is why microbrewers often use it in conjunction with American pale malt. I'm a little confused about what you mean by "haze" in a fermenting beer. Was it hazy when it went into the carboy, and did it not clear at all (with a large deposit of solids) within an hour or two. After the yeast takes off, of course, there's a whole new "haze" which is just two or three ***illion yeast cells performing their mating and working rituals. If the beer never looked bright in the kettle (taking into account all the stuff floating around in it -- take a spoonful out and look to see if the liquid itself is clear when the hop particles etc have a chance to settle), it's possible your boil is not vigorous enough. ======================================== On another note, has anyone ever gotten results anything like Charlie's from one of his recipes? He seems to bat them out at a fairly high rate, and I've wondered over the years how much time goes into developing each one, and whether he's ever brewed one of them more than once (or better yet, more than three times) before publishing them. What really struck me was his recipe in the most recent Zymurgy, which calls for (not having it in front of me, and whoops, here we go again relying on memory) something in the neighborhood of 3.5# of dry malt extract and about 3 pounds (maybe a little more) of specialty grains. This to produce five gallons of a beer over 1.065. Does anyone else think this is unlikely? - --Jeff Frane Return to table of contents
Date: 18 Mar 1993 08:49:35 -0500 (EST) From: STROUD%GAIA at leia.polaroid.com Subject: pH meter questions Nicks asks: >1) can I just use distilled water to calibrate at ph7? No. Distilled water is NOT pH 7, it is acidic due to dissolved CO2. You need to buy (or make) buffer solutions to accurately calibrate your meter. Your meter should also have some instructions about calibration. Many of the meters have two-point calibrations where you adjust the pH reading at, say, pH 4 and 9. Since pH varies with temperature, you also need to make sure that you calibrate it at the temperature specified by the manufacturer (unless your model has auto-temperature correction).

Date: Thu, 18 Mar 93 8:24:05 CST From: raudins at galt.b17d.ingr.com (Glenn Raudins) Subject: Temp. Controls / Freezer Re: Temperature Controls I would like some feedback on what people think of their temperature controls for their refrigs/freezers. Has anyone used the digital one from American Brewmaster? I like the idea of the digital ones, but I've only seen ones that go down to 40 degrees. I know Williams beverage sell one that goes down to 20 degrees but it does not have a digital display. Re: Refrig/Freezer Any recommendations on refrigs/freezers that have worked well for people? I seem to think that a chest freezer would allow the best utilization of space and it would allow the temperatures for lagering. Also, what results have people gotten lagering with just their refrigs (down to 40 degrees I believe)? Glenn Raudins raudins at galt.b17d.ingr.com Return to table of contents

I use a technique I saw here on the HBD once and has worked well. After cleaning, rinsing, and drying the bottles with your favorite method, take a small square (~ 2"x2") of aluminum foil and seal up the bottle opening. Then bake the bottles (theoretically nothing lives over 60C, but I use just over 100C) for 15 minutes and let them slowly cool. When you're ready to bottle, just take the foil off. I've done this up to 3 days before bottling and have never had an infection yet. -Karl Return to table of contents

I've found the malted rye (a tricky thing) but have a question. You see, I'm still an extract brewer and am not ready to go all grain right now. So I was wondering how I handle the rye malt. Should I treat it like a speciality grain by steeping it in near boiling water and then adding it to the regular malt? Or will I need to do a partial mash? How would I go about this?

I am concerned about nasties >falling into the bottles while they are waiting to be filled. Should I >bottle a six or twelve pack at a time to make sure no bottles are waiting >too long? I suggest that you keep the bottles with the open end down to prevent stuff falling into them. I can get about a case of 16 oz. bottles into a standard dish drainer. That's a pain since a 5 gal. batch takes about a case and a half of bottles. So, I picked up a drying rack. It's a plastic tower that holds up to 45 bottles and is expandable in increments of 9. I wipe it down with a bleach solution while my bottles are soaking, rinse the bottles with a bottle washer attached to a faucet, and then let the bottles drip dry on the rack. It works great and doesn't take up much counterspace. You might be able to make one out of wood, but I'm not sure you could keep it as clean as the plastic version. I bought it at a local homebrew supply shop for around $25. I've heard of other folks using the dishwasher set on rinse and dry, but that's not an option for me since I don't have a dishwasher or any room in the kitchen to put one.

Date: 18 Mar 1993 08:57:06 -0600 (MDT) From: Mark Taratoot <SLNDW at CC.USU.EDU> Subject: Chili Pepper Beer Greetings. I usually put half a chili in each bottle before sealing the crown. First slice the pepper lenghwise. Then remove the seeds (but not the inner white membrane) Rinse Put half (or two halves) chili in each bottle you want to "pepperize" Seal crown I have found that as soon as the beer is carbonated and conditioned it is at it's best "pepperness." The chili aroma and flavor seem to mellow with age. I cracked open a chili beer that had been sitting for a couple of months, and the flavor was there, but it was very subdued. So, maybe wait a couple of weeks if you want a beer that is at it's greatest pepper potential for cinco de mayo. I have tried putting chilis in with the boil, but the finished product did not have any "pep," just a bit of peppery flavor. Also, with the pepper in the bottle trick, you can make less than a batch of pepperized brew. Perhaps if you plan on crating more than one batch of beer to be consumed by may 5, then pepperize some of each and do a side by side by side by side comparison of all the pepperized/non pepperized beers. -toot Return to table of contents

Last I knew, you could also order them directly from: Jack Schmidling Productions 4501 Moody Chicago, IL 60630 +1 312 685 1878 You can also E-mail Jack for more info on current prices, retailers, etc. He is a little reticent about posting commercials, but will probably reply privately. I use both these devices and am quite pleased with them. You can build an Easymash yourself--Jack posts directions from time to time. If you want it done right the first time, Jack doesn't charge that much over the cost of parts for his kit, which has had some die work done on the air cock. The Maltmill is another thing again. It has custom castings, from recycled aluminum cans! I have no idea how Jack grooves the rollers, or where he gets the stock. It also is well-made and worth the investment. I have the non-adjustable version and have had no problems crushing various malts and even raw rye. I seem to recall that the Maltmill is about 120-125 dollars and the Easymash is about 25 dollars. If you order direct there is a small shipping charge, but only one charge for both ordered together. disclaimer--I have no interest in any of Jack's businesses.

The yeast is a washed version of what was used to ferment the beer. It is added to filtered beer to provide for the bottle conditioning. If there were faults with this yeast or the culturing method I would expect we'd hear about lots of problems from lots of homebrewers. I'd also expect there would be some evidence of such a problem in Sierra's products. I can't say I've ever had a bad bottle of anything that Sierra Nevada produced. As for the OG recommended for starters: I believe George Fix did some research (or at least referred to somebody's research) which indicated that the performance of yeast was best when begun in a starter which was close to the OG of the batch to be pitched.

The subject came up at our homebrew meeting last night, and Fred Lang, the brewmaster at our local micro, agreed with Micah. He said to put the dark grains in for just ten or twenty minutes at the end, while mashing out. Also, not too long ago, Joe Stone and I wondered about sparge times. This subject also came up at our meeting last night. One guy said he aimed for 2 and a half to three hour sparges. Another person said, "Gee, I just do it for about twenty minutes." Again, the question was put to Fred. He said that the length of time is really irrelevant, because it depends on your grain bed, temps, and other things. He maintained that you should use the gravity to determine when to quit sparging. In particular, do not go below 2 degrees Plato, and in fact you should quit a little above that since it would be better to throw out a little extract rather than get the tannins. So what's 2 degrees Plato? Like 1.008 maybe?. Looks like those of you who stop at 1.010 have been talking to Fred... Just thought you'd be interested, - --frank Return to table of contents

Thomas" <Spencer.W.Thomas at med.umich.edu> Subject: Bock recipe Well, I was going to wait until after this beer won the Bock is Best competition :-) to post this, but a friend asked for the recipe, so I'll kill two birds with one stone. Since this was the first batch in my new mash/lauter tun, the procedure required some fine-tuning. Thus the multiple infusions, etc. This may make it difficult to exactly reproduce the recipe! I made this on Dec 26, so it's Boxing Day Bock 10# Belgian Pilsener Malt 3# Belgian Munich Malt (above Corona crushed) .5# M&F Crystal malt 2 oz chocolate malt (above pre-crushed by roller mill at the HB shop) 4oz Hallertau plugs at 2.9% 2oz Saaz plugs at 3.1% Wyeast Munich Lager yeast (2308) Procedure: Mix Pilsener & Munich malts in mash tun, infuse 10.5qts H2O at 170F (mash temp 137F -- oops!), infuse additional 3qt at boiling (mash temp to 145F - -- sigh!), decoct 3qts (pretty thick) to boiling (mash temp to 156F -- finally!) Meanwhile, steep crystal in 1qt H2O at 165F. Mash 1hour. Infuse 3gal at boiling to 165F, add crystal & chocolate malts & stir. 15min rest. Start sparge, recirculate 6 qts. Sparge to 6.5gal (ending sparge gravity 1.010 at 150F == 1.026??) Boil 1.5 hours. Hop schedule 2 oz Hallertau at 30 min 1 oz each Hallertau & Saaz at 60 min 1 oz each at 75 min Chill & rack. Yield approx 4 gal at 1.066. Pitch yeast from 1pt starter. Move to cellar at 58F. After two days, krauesen is evident, move to fridge at 50F. Primary time: 6 weeks 24 hour diacetyl rest at end. Bottled at FG 1.022, lagered in bottle. Comments: It came out as a borderline "Helles Bock." Probably should have left out the chocolate malt. This stuff is yummy. Wonderful malt nose & flavor. Nicely hopped. Friends have said it's one of the best beers they have tasted. I have to attribute much of its goodness to the ingredients: Belgian malts and hops plugs. This is the first time I've ever really smelt the "spiciness" of Saaz hops. I wonder whether the little decoction I did to get the mash temperature up had some effect on the maltiness. =Spencer W.

I have no hard data, but my brewing has increased manyfold over this flu season, to a point where I nearly never buy commercial beer anymore. (Less than one case in 6 months). For the first time in years, I have not gotten a single cold through the flu season. I attribute this to greater increase in vitamin B intake. Drew Return to table of contents

Has anyone ever tried to sparge after a 10 minute mash? Sounds like a good test for Jack S. with all that time to burn! I have no access to GW malt but I always do the iodine test at ten minutes. Most domestic malt is just about fully negative at this point and the times I have checked it in 5 minutes, there has been a significant reduction in starch. As I do not really understand or trust the iodine test, I still usually mash for one hour.

A vigorous boil we want, but in most cases (i.e. for most styles) we don't want to caramelize the wort. The higher the heat, the more the wort caramelizes. This would not be good in a Pils style. Judging from all the interest in getting that caramel flavor recently displayed on the Digest, I presume that lots of people would not find that a problem. More importantly, Ken Pachivich at Bader Brau makes an issue of his "fire brewed" process to achieve that caramel taste for his award winning Pilsner. He brags about how hot the fire must be to achieve caramelization. El Cheapo Easymasher.... The idea for this one came from McHarry and if you find me pushing a shopping cart full of empty cans, you can blame him. He, of course, stole an idea from Benjamin but I couldn't understand the latter's drawing so, he beat me to it. This is the ultimate (in simplicity) EASYMASHER. In fact it will probably always be an easymasher (lower case) because I can't think of any reason anyone would pay me to make it. ______ | | | | | | | | 3/8" O.D.

Date: Thu, 18 Mar 93 10:29 PST From: Paul AndersEn <ECZ5PGA at MVS.OAC.UCLA.EDU> Subject: Beer and Cancer Hello fellow brewers, Now I could be wrong, but, while doing research for a paper in my Biology of Cancer class here at UCLA, I found some articles which described studies being done in Europe regarding the effects of beer and alcohol in general on the risk of colorectal cancer. What they seemed to be saying was that spirits and wine did not increase the risk of colorectal cancer, but they found that beer did. Of course the risk was substantially increased only in subjects who drank large amounts of beer regularly over the course of a lifetime. There was also a link to dark beers and smoked foods, such as fish. I did not end up writing my paper on this topic, so I cannot give any references, however, it would not take me long to look them up again if anyone is interested. If anyone else can shed some light on the subject, feel free. By the way, I tried the new Pub Daught Guiness in the can for the first last weekend and I loved it. Just for fun I ripped open the can to check out the doohickie on the bottom: pretty cool. If you haven't tried it yet, and you like Guiness, go out and get some. It is amazing how it looks and tastes like it came out of the tap. My only gripe is that you have to open it cold (otherwise you have beer all over the place: like homebrew). I haven't seen it in too may stores though. In southern california you can get it at the Price Club (although it may be seasonal). It sure made my St. Patricks Day.

I think that this may be your problem. 3 tbsp in 3/4 quart is an *very* low gravity wort. Even the 1020 wort that I use barely if ever shows any kraeusen -- besides there being very little sugar for the yeast to get excited about, the viscosity of the wort is so low that no "head" forms. You probably have a fine yeast starter, albeit a bit weaker than it could have been. If you want to continue to use the juice jar for your starters, get a one-hole stopper to fit the top and put an airlock in it. The airlock will show you activity a lot more accurately than watching the surface of the starter. > I called the supply house where i got the yeast and they mentioned >that the low pressure storm system which just came through Phila may have >caused the starter to mis-start. This seems suspicious to me, however, >because I've never heard of problems at higher elevations where atmospheric >pressure is also less than at sea lever. Ridiculous. Perhaps all the yeast in the US is now dead thanks to this low pressure storm system?

This has The sludge is a combination of hop petals that made it through, hop resins, dead and dormant yeast and probably a couple of other things. Leave it be. The sludge is expected, but if you still think you want it in your beer, taste it and decide for yourself. ****************** Chris writes: >Once the bottles are boiled, bleached, NaOH'ed, etc. . .where do you keep >them before they are filled and capped?

I bought a bottle tree and a sanitizer thingamabob. It mounts on the top of the tree. I pump bleach solution into the bottles (30 pumps) and then set the bottles onto the tree. When I've got two cases on the tree, I rinse the first bottle, fill it, cap it and then go on to the next bottle. Perhaps you may want to sanitize all your bottles (even if you leave them face up) and then rinse just before bottling. This way, if anything falls in, the residual sanitizer will kill it. ************************ I wrote: >>fermented at maybe 1 bubble per 30s.
