---------------------------------------------------------------------- Date: Mon, 15 Feb 1999 10:30:16 -0600 From: "Donald Fischer" <dlf560f at mail.smsu.edu> Subject: Sanitizing Bottles I've got a question for the collective that involves sanitizing bottles. For the first couple of years that I brewed I would thoroughly wash my bottles in B-Brite just before bottling (soak & rinse w/ hot water using the standard jet device attached to my kitchen sink faucet) -- no chlorine or iodide sanitizing. I was using the same procedure for my fermenters, ciphoning hoses, & other paraphernelia -- just thorough washing with B-Brite. Although I was generally happy with the results, a couple of infected brews that I had to pour out got me to change my ways. For the last six or seven batches I've been soaking EVERYTHING in chlorinated water for at least 30 minutes. If I'm just brewing (not bottling) it doesn't slow me down much. If I'm trying to bottle & brew on the same day it's turned a fairly pleasant 5 hour job into a 7-8 hour marathon. A batch or two ago I started doing what a guy in our local brewing club said he does to streamline the process. I wash/sanitize the bottles days (or weeks) before I brew. I fill the washed bottles to the brim with the sanitizing solution and "cap" the bottles with a 2-inch square piece of heavy duty aluminum foil, squeezing the foil tightly around the top of the bottle (it makes a tight seal). When it's a brew day & I want to bottle a batch that's in secondary, so I can transfer a batch from primary & make space for the next, I just dump the solution from the bottles, rinse w hot tap water & drain. Here's my question: I notice the aluminum foil is often slightly tarnished when I remove it (especially the part that covers the top & makes contact with the solution). I also notice a faint salt-like residue on the bottle top & around the side where the foil makes contact with the glass. Are the tarnish & slight residue related? Is either toxic? Does anyone else use this procedure? Here are some additional facts: my sanitizing solution is about two tablespoons of generic house hold bleach per 5 gallons (I mix it up in my primary fermenter -- a standard 7 gal, white plastic bucket). I'm on a chlorinated city water system, so my tap water is also chlorinated. Thanks for any info & advice.

It was said to be casked conditioned. I would classify it as a "robust" stout because of it's hop profile. The publican had little knowledge of its origin. Can anyone shed some light on it's brewery?

Date: Tue, 16 Feb 1999 13:34:01 +1000 From: hoshido at gman.rme.sony.co.jp (Mutsuo Hoshido) Subject: Improved Kome-koji process for homebrew Sake I had a sake brewing job experience at an old-fashioned and traditional sake brewery,Matsuya sake brewery,on Feb.7. Thanks to the President Mr.Matsubara's openminded explanation about sake brewing and Kome-koji process,I was saccessful to make my own Kome-koji at home,the same appearance and the same taste as that of the sake brewery. Key point is to steam cook rice as dry as possible by very short time of washing and soaking together. Equipment and materials I used: 1.Normal eating rice 2kg ( I used "Hitomebore"rice which is one of the tastiest rice kinds in Japan.) The sake brewery used so called 60% polished special sake rice kind. (40% reduced from original rice. Material cost increased 40% plus polishing expence. ) 2.Stainless steel bowl and basket to wash and soak rice. 3.Steam cooker. 4.Cotton cloth, a loose open weave.(Traditional Sake brewery uses hemp cloth.) 5.Thin wooden container or Sushi cooked rice container. 6.48L picnic cooler box. 7.A 60W tungsten lamp together with a small fan which is controlled by a Robertshow type temperature controller. 8.Dry Koji-kin or Koji-fungi. I got a pack thanks to the Sake brewery president,Mr.Matsubara. 9.Ethylalcohl spray to sanitize hands. Improved Kome-koji from dry Koji-kin or Koji-fungi 1. From 13:00 on Feb.11. Wash and soak the 2 kg rice for about 30min. in a Stainless steel basket together with a bowl and them remove the bowl. Drain the water at least 60 minutes. 2. Wrap the rice with a cotton cloth and steam cook it for 60min with weak gas flame. Steam cooked rice looks slightly transparent and well separable, not white and not sticky,because of less content of water. 3. Spread and separate the each rice on the other cotton cloth in a wooden container by hands to cool down the cooked rice to 30dgC (86degF) which I don't feel warm temperature anymore. 4. Wrap about a few gram of dry Koji-kin or Koji-fungi with a gauze. And sprinkle the Koji-kin or Koji-fungi on the cool rice and well mix it by hands. (Dispose remaining rice of dry Koji-kin or Koji-fungi in the gauze after spinkling) 5. Wrap the rice with the cotton cloth in the wooden container and slightly moisten the cotton cloth with water spray. Put the rice together with the wooden container in a picnic cooler box with the temperature controller set at 30 deg C (86degF) . 6. At 06:00 on Feb.12. The rice started to stick together. Well separate the rice with hands. After wraping the rice with the cotton cloth. Moisten the cloth. 7. At 21:00 on Feb.12. Kome-koji alreasy started to smell out side of the picnic cooler box. 8. At 06:00 on Feb.13. The Kome-koji stuck together. Well separate the Kome-koji with hands. After wraping the rice with the cotton cloth. Moisten the cloth. 9. At 17:00 on Feb.13. Remove the already prepared Kome-koji from the picnic cooler box and cooled down to the room temperature by spreading the Kome-koji on the other cotton cloth on a clean table or plate. The uniform well separated beautifully white Kome-koji is made. Slightly sweet taste the same as that of Sake brewery. 10.Put the Kome-koji in a Ziploc and keep it in a refrigerator for homebrew sake or miso making. End Return to table of contents
Date: Mon, 15 Feb 1999 22:27:03 -0800 From: jim williams <jim&amy at macol.net> Subject: netscape/3 decoction pilseners Hello, Thank you everyone that replied to my netscape question. I think I got it all sorted out. Thanks again! On to brewing. I'm considering a 3 decoction Pilsener, bohemian style. I know there are many ways around the triple decoction. I'm considering, just as much to say I've done it than anything else, and for tradition sake. I do single decoctions on all of my weisen, and my alts. I'm not totally out there in terms of decoction, but triple.... Anybody out there do this? And swear by it? What do most of you use for mash schedules/malt choices? What about ditching the decoction and using some melanoidan malt, which I've never used. I'm looking for the malty/bready/bitter/hoppy smoothness of Pilsener Urquell. What about yeast strains? In the past I've used the wyeast czech strain. Has anyone used anchor steam yeast on this type of beer at room temp? What about this yeast with other styles of lager? Thanks, Jim Return to table of contents

Date: Tue, 16 Feb 1999 08:09:48 -0500 From: John Herman <johnvic at earthlink.net> Subject: strange mash I was mashing for a barley wine yesterday. My system can only handle 14 lbs. of grain at most. My plane was to mash and sparge in 2 halves. The first half went well. During the second half I had a lot of trouble controlling the temperature and I was getting inacurate temperature readings, ( due to not mixing enough - lesson learned! ) and it mostly stayed around 140 degrees. After 2 and a half hours I gave up. When I started the mash there was a lot of fine powder and the mash looking milky. After I gave up it looked more like light brown peanut butter. I've learned my lesson ( good ), and have 2 gallons of barley wine brewing ( the wort tasted delicious - great ). My question is, what is up with that peanut butter look? - -- \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ * Bicycling, Bassing and Brewing * * * * The Real 3 B's! * * * * John Herman * * johnvic at earthlink.net * ////////////////////////////////// Return to table of contents

Date: Tue, 16 Feb 1999 08:58:20 -0500 From: Dan Listermann <72723.1707 at compuserve.com> Subject: Attenuation Michael Pratt ( Michael.Pratt at ottawa.com) complains that his recent batches are finishing with a rather high gravity. He goes through the things he has done with yeast, aeration, pH, ect. to reduce it. I have found that these factors are not main effects. I am sure that they have some bearing, but if you really want to improve attenuation increase the mash time and keep the temperature low. You have to have sugars that will ferment.

Date: Tue, 16 Feb 1999 09:11:33 EST From: MaltHound at aol.com Subject: re:alcohol and beer port On Fri, 12 Feb 1999 09:56:45 -0800, "Bryan L. Gros" <gros at bigfoot.com> says: "I've been getting into port wine lately, and I was thinking about beer port. As you know, port is made by the winery adding grape brandy to the fermenting wine 2 to 3 days after fermentation begins. The result is that the added alcohol wipes out the yeast, ending fermentation and thus leaving residual sugar behind. The beer analogy would be to take a barleywine type wort, begin fermentation, and then 2 to 3 days later (maybe longer), add scotch to the fermenter to up the alcohol and leave the unfermented sugars behind." ***QDA - ON*** I would hazard a guess that the port makers do this as a means to achieve a desired sweet taste in the end product, not necessarily to increase the alcohol levels, though that is certainly a byproduct of the process. Invasively halting fermentation would be necessary to achieve that end since the sugar source (grapes) are limited in sugar content. This is entirely conjecture on my part. ***QDA- OFF*** OTOH we malt brewers typically boil our raw materials anyway and concentrating the wort to increase the sugar concentration is easy. In any case I have been very successful in producing very sweet beers in a couple of ways without the need for unnaturally halting fermentation. One thing that I have noticed is that the *perception* of sweetness in beers is more directly related to the lack of a balancing hop bitterness than it is to the actual presence or lack of residual sugars. Starting with a wort of high (<1.100) gravity is likely to leave a fairly heavy and sweet beer after the natural end of ferment. This seems true even with fairly aggressive hopping. A beer made like this with a TG in the 1.025-1.030 range seems to exhibit a satisfying sweetness that shines through what otherwise would unbearable hop bitterness (75-100 IBUs.) It might be possible to create this same sort of malt / hop balance in a lower alcohol brew by arresting fermentation, but using alcohol to do the job would seem counterintuitive.

Date: Tue, 16 Feb 1999 09:21:29 -0500 From: "Peter J. Calinski" <PCalinski at iname.com> Subject: Re: Fermentation woes Mike, I have had the same thing happen. I used to get very volatile fermentations and low FGs. Now they are slow and the FGs are higher. I believe they are the result of changes in my technique. I was getting some "off" flavors so, I lowered my pitching temperature and improved my trub and hop management. I used to pitch at 80F, 85F, even 90F based on advice from someone. I was also keeping it at 75F or higher depending on the room temperature. Now I pitch at 70F-75F and ferment at 65F-70F. I get, as I said, very mild fermentations and higher FGs. I also believe that when I pitched at 85F and kept it at 75F, the wort stayed at close to 85F for the 2-3 days of primary fermentation. The fermenter just doesn't cool much because the temperature differential is so small. So, even if the storage temperature is low, if the pitching temperature is high, the effective fermentation may be quite high. The other things I have done are better trub management and use of hop bags. I used to just toss the hops into Th. boil then, siphon everything into the fermentor. I am sure that the break material and hop particles contributed to some of the off flavors but it may also have helped the fermentation. I used to be sloppy about bottling and would sometimes get some hops into the bottle. Often, these bottles would be considerably over carbonated compared to the bottles without hops. Thus, I concluded that the hop particles helped the yeast make more CO2. Maybe the hops or trub I was siphoning into the fermentor helped the yeast get the gravity down. So far I am pleased with the reduced off flavors but dissatisfied with the higher FG. Hope this helps. Pete Calinski East Amherst NY Near Buffalo NY 0 Degrees 30.21 Min North, 4 Degrees 05.11 Min.

My source for this information is a weekly news magazine, Science Digest. Unfortunately, this is by memory, since this controvery actually occurred in the mid-70's. I can't specify the exact issues. I remember it because I had just graduated with a BS in Chemistry and subscribed to the publication through the mid-70's. It was an interesting controversy. The source was an experiment done by students in Chem Lab at an unknown (forgotten) college. One of the students was late in getting to the lab and his lab result, a bowl of hot liquid, was much hotter than the ones from the other students. They had time to let their bowls of liquid cool to room temperature. Nonetheless, he put his overheated bowl into the freezer along with the other room temperature bowls. He discovered that his bowl froze rock hard while the other bowls were still "slushy". He asked the professor why hot liquids froze faster than cold liquids, and was told that that was impossible. Nonetheless, it happened. A series of experiments were undertaken and they confirmed the results: Hot water froze faster than room temperature water. More experiments were done to determine why. The answer turned out to be surprisingly simple. Under "open cup conditions" hot water freezes faster than room temperature water. I know that this sounds counter-intuitive, but evaporation is something that most people don't consider. Let's define "open cup conditions". Picture putting two simple coffee cups of water into a freezer, one cup with hot water, the other with the identical amount of room temperature water. The cups have a significant amount of surface area exposed to the cold. The cup with hot water will freeze faster. It will do so because hot water evaporates quicker than cooler water. What really happens is that enough hot water evaporates to reduce the mass of the water in the cup, and a smaller mass freezes faster. Put a lid over the cups, and you're right. The hot water takes much longer to freeze than the room temperature water. I assume that Science News is still available in some libraries. The on-line version only goes back to 1996.

Date: Tue, 16 Feb 99 10:58:35 EST From: SBireley at renex.com Subject: RIMS Pumping Problems with Lager malts A friend and I have been all grain brewing for several years, the last two using a bottom fired RIMS setup. We brew about once a month or more and have accumulated a fair amount of experience. Our current setup is a 3 tier system with sankey kegs for the kettle, mash tun, and hot liquor tank. We have a stainless steel centrifugal pump with electronic speed control, and 3/8" ID 1/8" wall Tygon tubing for plumbing. We use an ABT false bottom in the mashtun with a 1/2" copper manifold to distribute the wort on top of the grain bed. We brew 12 gallon batches so our grain bill is 20 to 35 lbs of grain depending on the target OG. We crush our grain with an adjustable JSP Malt Mill which works very well. When brewing with Briess or Canadian Malting two row with up to 40% Munich Malt, the brew nights are flawless. We can pump fast enough to get 2 deg. per minute rise during boosts without scorching the bottom of the mash. We have used both a stepped mash program and a single step infusion program with great results, leaving plenty of time to enjoy the products of our labor from previous brew nights. Wanting try other malts to brew European Style beers, we have experimented with Crisp Lager Malt, DWC Munich, Durst Munich, and Durst Pilsner Malt. The problem we have encountered with all of these malts is the mash bed compacting to the point of sticking during recirculation. The mash is still loose enough to run-off during lautering, but we cannot maintain a pump speed high enough to boost the temperature of the mash bed to mashout. Repeated stirring to break up the compaction works for a couple of minutes, but it compacts again. Using these malts, the mash seems to be more sticky than with the Briess or Canadian Malting malt. We have tried: adjusting the mill setting to get a more course crush; adding a lb. of rice hulls to the mash to help keep the bed loose; pumping up through the mash be to keep the bed fluidized, but we did not have a suitable filter to keep grain out of the pump. This did show some promise though. None of these worked satisfactorily. Has anyone experienced this before? Does anyone have an idea how solve this problem?

Date: Tue, 16 Feb 1999 09:23:42 PST From: "Drew Avis" <andrew_avis at hotmail.com> Subject: Re-pitching Yeast + Hops? Dear HBD, A question that has been bothering me for a while: I like to re-pitch yeast collected from the secondary. I also like to dry-hop with pellets. Is there a problem with re-pitching all the sediment (yeast and hops)? I realize I should wash the yeast, but my house is populated by dogs, cats, and a tortoise (in other words, it's an unsanitary, chaotic mess), so I try to keep it safe by handling yeast as little as possible. On hot vs cold water freezing - the following site covers it pretty well. I've included the references from the page: http://www.urbanlegends.com/science/hot_water_freezes_faster.html "Hot water freezes faster than cold water. Why does it do so?", Jearl Walker in The Amateur Scientist, Scientific American, Vol. 237, No. 3, pp 246-257; September, 1977. "The Freezing of Hot and Cold Water", G.S. Kell in American Journal of Physics, Vol. 37, No. 5, pp 564-565; May, 1969.

Of the few relevant studies out there most seem to be from the early 1970's (I didn't go back any further than this so it's possible there is more out there). From scanning abstracts and pharmacology texts it seems pretty clear that there are many potential contributing factors involved in developing a hangover and that no one seems to know what extent each of these actually plays in the process. Such factors include toxic metabolites of ethanol and methanol (formaldehyde, formic acid, acetaldehyde, acetone, etc) which are detectable in the blood and urine, changes in blood glucose levels, circulating hormones and blood pressure, dehydration effects, etc. One paper specifically focused on fusels. "Comparative analysis of the effects of alcoholic drinks on different qualities" Z Rechtsmed 1978 Mar 28; 81:31-43 (German). In this paper the authors compared the effects of drinking drinks rich in fusels vs drinking the same amount of pure diluted alcohol. They concluded that, "It was found that alcoholic drinks rich in fusel oil produce a more deviating EEG curve, an increased worsening of physiopsychic performance and of clinical and subjective symptoms."

Date: Tue, 16 Feb 1999 15:17:13 -0500 (EST) From: Paul Ward <paulw at doc.state.vt.us> Subject: Am I Prescient? A couple of months ago I wrote asking about the possibility of using our Vermont climate as a cooling source in winter due to my garden hose being frozen into is' winter shape. The unanimous reply was, "Don't be such a cheapskate, buy a dedicated hose for brewing and keep it inside!" So I did. I finally got around to brewing that honey/wheat (although I only used 2.5 lbs of honey rather than the 5 lbs. I originally planned). I added an ounce of Saaz pellets at 10 minutes before knockout, and started hydrating the Safale dry yeast. I wish someone had told me that my son had 'borrowed' a hose to drain his hot tub, I would have planned my disasters better. DATA POINT - it takes 4.5 hours to cool an original volume of 6.5 gallons of 212 F wort to 70F with an ambient air temp of +30F to start and -2F at the end. You will also lose about a gallon of wort due to evaporation. [NOTE: I kept the kettle lid on for the first 2 hours until the sun set and all the chickadees went to roost and then I removed the lid half way to try to cut down DMS trouble]. My poor yeast had finished proofing, couldn't find anything to eat, so they went nighty night during this 4+ hour period. Am I correct in assuming that my Saaz aroma hops passed into the flavor and/or bittering range? Will it contribute much bittering without an active boil? Will there still be noticable flavor components left? By 5:30 this morning I had some fermentation evident, so I know that some of my yeast survived, and I'll end up with beer, just not sure how it's going to end up (but I'm an optimist). On an unrelated note - I attended a tattoo convention in Portland Maine this last weekend. Had lunch at Gritty McDuff's Pub - wonderful pale ale. After a couple or pints and a great meal, we walked 3 blocks to the Shipyard brewery and took the tour. The tour guide didn't show up, so the kid running the gift shop took us around. He didn't know anything about brewing, or much about the plant, but that was O.K. too (I got to stick my nose into a 55 gallon gallon drum of Tettnang hop pelletts and inhale). I was surprised that they let us walk around in the room with all their open fermenters. They have no idea what sort of yeast I may have on my person that could cause a problem with their Ringwood strain. The kid from the gift shop didn't seem to care. I was surprised that they're only running at about half their capacity. They're either carrying quite a dead debt load or they're poised for major and rapid expansion. Nice brewery, so-so beer. Tattoos, brews, and ocean views make a great weekend. Paul in Vermont paulw at doc.state.vt.us - -- According to government height/weight charts, I'm seven and a half feet tall.

Date: Tue, 16 Feb 1999 12:24:25 -0800 From: "Mark Riley" <markril at jps.net> Subject: No Protien Rest = Chill Haze I've been following the protien rest debate for some time and over the last year I've made several ales and lagers without using a protien rest and have found that these very same beers have a stubborn chill haze that won't go away with "lagering". Now, supposedly the pros say that a protien rest is "unnecessary with todays malts" but do these same pros not care about chill haze because they're all filtering their beers and this is a non-issue for them? On the plus side, I notice that these beers do, on average, form a better head. A nice head is important for appearances, but I also think that clarity is just as important. Some of the malts I've used are DWC Pilsner, DWC Pale and Hugh Baird Pale. I generally use Irish Moss and don't use finings on the finished beer. I'm wondering if something like mash pH might be more critical when not doing a protien rest (don't know this, just wondering). Is seperation from cold break an issue? I realize that chill haze is of no consequence to many brewers here, but darn it, with some of you out there posting so emphatically that a protien rest is taboo, I'm wondering what gives?

I was thinking that maybe I could simulate aging by microwaving. Here's my plan to get 3 oz aged hops: 1. Take 4 oz Cascade pellets, originally 5.7aa, but now over a year old. 2. Put them in a microwave safe bowl and nuke them for 15 seconds on high. 3. Crumble the hops. Taste them - note bitterness. 4. Repeat steps 2 and 3 several times, until they taste about 1/4 as bitter as when I started. Has anyone tried anything like this? Will it work, or am I off base? Comments?

In fact the flow rates have a marked effect on the rate of transfer. As you might expect turbulent flow is much more efficient at transferring heat than laminar. A few years back I looked at this problem and tried to come up with a simplified approach to characterizing wort chiller performance. I came up with a single parameter which I called "chilling capacity" and symbolized by Q. Q is in gallons per hour and and represents the amount of wort which can be cooled per unit time to within 3 F of the cooling water temperature provided that the coolant flow rate is 5Q or better. Chiller efficiency (defined as the wort temperature drop in going through the chiller divided by the difference between entering wort and coolant temperatures) can be determined for arbitrary values of wort and coolant flow, from a family of curves in which wort flow is plotted against coolant flow, both normalized by Q. The curves are parametric in efficiency. They can be found in Brewing Techniques Vol. 4 No. 4 (July/Aug 1996) in an article starting on p 42. Much of the appeal of this approach is lost because Q varies with Reynolds number. Thus it increases with wort flow rate making the chiller more efficient while at the same time the same time the faster wort flow means less wort contact time in the chiller and thus less efficiency. These two effects offset each other to some extent up to the point where the wort flow is totally turbulent and increasing it does not increase Q further. In practical application, this wort flow rate would never be reached. I experimented with 3 chillers and found Q linear with wort flow. The first was the Hearts for which Q = 1.1936f + 101.2 where f is the flow rate in gallons/hour. The linear model is valid over flow rates of 24 - 110 gph) The second was 25 feet of 3/8 inch tubing coiled inside a 5 inch PVC pipe (the different form factor does not change the basics of operation or the model). For this chiller Q = 1.6521f + 19.8 (1 < f < 44). A third chiller was constructed of 50 feet of refrigeration tubing in 50 feet of garden hose. For that chiller Q = 3.4481 + 21.6 ( 5 < f < 115). These are graphed in the article. Using the efficiency vs. normalized flow curves in the article with these Q data and recognizing that Q is directly proportional to the length of the chiller you ought to be able to come up with some rough design parameters. Don't consider this and advert but for the price, performance (can chill 30 gph with 98% efficiency) and lack of trouble the Heart's is a pretty good deal IMO. Return to table of contents

So far, I've seen only one poster who has actually done an experiment on all this cold/hot water silliness. I did one several years ago, on a bet with a friend who claimed that boiling the gases out of water made it freeze faster. One was cold tap water, the other had just been boiled (at 2800 feet above sea level). We didn't take the temp of either, just set them outside in identical glass bowls on the roof of the car, in well sub-freezing weather. The cold water froze faster. A lot faster. When it was frozen solid, the other one was just starting to crystalize. To those who keep posting the results at: http://www.weburbia.com/physics/hot_water.html Take the time to actually read it. The title, "Hot Water Freezes Faster than Cold!" is misleading if not downright dishonest. The "cold" water is 50C. That's 122F. Cold? I don't think so. A better title would be "Extremely Hot Water Freezes Faster than Hot!" tim (Jeeze, what a grouch!) == Please ignore the advertisement below.

I have noticed that while it seems to drop and clear quite quickly once primary is over, in the bottle it seems to be rather powdery; it doesn't really pancake very well. Is this the usual experience for this yeast? Flavor-wise, it seems quite nice; Some sulfur and diacetyl at first, which very quickly (one,two days) goes away at warmer (60's) temp.
