---------------------------------------------------------------------- From: "Norman Brewer" <NLBREWE at msn.com> Date: Sun, 22 Sep 96 19:16:10 UT Subject: Real world rims experience I have a rims system with 72 inch heating element and have brewed about 12 batches with it so far. I use the heating element to raise the temperature of the mash, and while it is raising the temperature, the heat is full on, providing about 1200 watts of heat. I remove the element after each batch, and have noticed that it usually is covered with a soft tan colored film which easily washes off. There is no scorched material on the element, and no carbonization is evident. This was not always the case when I brewed in a pot on a propane heater. The circulating wort is transparent and the color depends on the type of beer being brewed. Basically everything that goes into the boil is clear, but there is still lots of hot break and cold break material precipitated out in the boil and cooling. From the boil on, the brewing cycle is exactly the same as with any other mashing technique. I typically get 30-32 specific gravity points per pound of grain, have no problems with fermentation, and brew excellent beers with the rims system, so I'm happy. Return to table of contents
From: MadAntBrew at aol.com Date: Sun, 22 Sep 1996 17:28:31 -0400 Subject: Brewing Beers Like Those You Buy I just picked up a copy of this book at my local library looking for some new info to read. It has a great collection of English stye bitters, pales, old-ales etc., my kind of beers!!! The book was published in1978 when homebrewing methods and supplies were not as they are today and many of the recipes include "light or dark brown sugar, demerara sugar and saccharin tablets!" My question is , are these outdated ingredients? Does brown sugar add some wanted character to these beers as opposed to being cidery.I can't imagine adding saccharin to beer, I know it won't ferment and will add residual sweetness but I think I'll stick to crystal or cara-pils. Any thoughts or experience with these recipes or ingredients? Return to table of contents

The best method I have ever seen for hot or cold wort is to use a Chore Boy (R) unsoaped (copper or SS) scrubbing pad at the bottom of the racking cane. insert the cane about halfway into Chore Boy. wire it in place with a bare, heavy copper wire. Place it at the edge of the bottom of the whirlpooled kettle and syphon. Works great at filtering out the hops and the trub. - ------------------------------------------------------- Ajunde asked about using Corn Meal as an adjunct. It works fine if you cook it separately before adding it to the mash. Usually about 20-30 minutes. If you don't add enough water you can always have corn meal mush or polenta while it is hot. Let it stand overnight and cool to room T or lower and you can slice and fry it and serve with butter and syrup. Delicious! I prefer instant grits. I suspect these can be used without precooking, but have never tried it. I also have another method I detailed a few weeks ago in which I use 2# pale malt, milled and bring this adjunct plus malt up to boil slowly ( 2 deg/min) or stage it up through saccharification and then boil. this substantially reduces the viscosity. Cooking this a long time ( say 30-60 min) gives what I call a pseudo-decoction mash of the adjuncts. Use this latter method to boost the maltiness and increase the color of your American Lager. - --------------------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3203 at compuserve.com Return to table of contents

Three years ago I brewed an extract Marzen using Irekes Amber Extract, Hall.&Tetn. hops and Wyeast 2206 Bavarian Yeast. This beer had a wonderful spicy flavor. I contributed the spice to the yeast.

From: ajdel at interramp.com (A. J. deLange) Date: Sun, 22 Sep 1996 22:53:30 -0500 Subject: Water Softeners David Sprague asked about brewing with softened water. His post indicates that he is aware of the principal result of softening with the usual type of home softener: all the cations [ Ca++, Mg++,K+, Fe(++/+++)] are replaced by Na+ and the anions are unchanged. The problem with this is where the hardness is largely carbonate. Such water is highly alkaline but where the bicarbonate is paired with calcium one can remove some of it easily by simply boiling the water or depend upon the reactions of the calcium ions with phosphate in the grist to lower the pH into the proper range. If the calcium is absent neither of these options remains. Sodium is more or less of a "don't care" ion except where it is present to the extent that the beer tastes salty. I leave judgements as to the health effects of sodium to the individual. Softeners are now available which replace the cations with potassium for those who are concerned about sodium intake. David says the water in his area has 13 degrees of hardness. Where are you? Degrees usually means German degrees but there are also British and French degrees and the US unit of 1 mg/L as CaCO3 is sometimes called a degree so tell us what the unit is (or let us try to guess from your location) and we will be in a better postion to comment on how hard the water is and what to do about it. Some beers are brewed with very hard water with no problem. A.J. deLange Numquam in dubio, saepe in errore! ajdel at interramp.com Return to table of contents

I just picked up a six of Sam Adams Oktoberfest. I know Sam is usually an "Americanized" (watered down) version of most styles, so I'm asking, what commercial brew is to Oktoberfest what Guinness is to Stout? I think I read in the HBD that Munich malt is typically used in Oktoberfest, but the Sam's label doesn't mention it. It says crystal, caramel and harrington malts are used. (Harrington?) Opinions?

Is this a commonly known fact? Is aluminum really that much better than S.S. for cookware? Why does every home (or commercial for that matter) brewery use S.S. for mash tuns, boilers and hot liquor tanks if it causes "hot spots"? > Unfortunately, heavy gauge aluminum would be far too expensive for a 10 or 15 >gallon pot. I gotta disagree. I visited my local restaurant supply house and saw (IMO) heavy gauge aluminum 40 qt. stockpots for about $70. Less than half the price of a comparable Vollrath S.S.! I would have long since picked one up, but it seems we never have decided whether or not aluminum makes good breware. I don't mean to kick up the Alzheimer's/off-taste thread, but I'm beginning to understand why it's a popular question. Aluminum pots are cheaper, and now it seems that they're better heat conductors. My question is why isn't EVERYBODY using them? I'm ready to put an end to this fear of aluminum once and for all. If somebody will send me a pint of aluminum-brewed homebrew (all-grain preferably, so it'll include mash and boil), I'll pay to get the lab analysis done to see exactly how much Al is leached into our beer during brewing. If it's very little to none, then we'll know there is no problem. If it's a lot, then we'll back up, regroup, and decide whether or not it matters.

From: Jeff Renner <nerenner at umich.edu> Date: Sun, 22 Sep 96 22:13:24 -0400 Subject: Re: Corn Meal as ajunct? AJUNDE at ccmail.monsanto.com asks: > I've been itching to ask this question since my visit to Chippewa > Falls last year. Linenkugles uses corn meal as an ajunct. I assume > this it to raise the alcohol content and lighten the body, but, how > > Can you add it directly to the mash, or should you boil it first? Corn does much more than you suggest, it adds a wonderful flavor and sweetness. It goes especially well with the characteristics of 6-row malt. Brewers use brewer's corn grits, which are degerminated and de-branned pieces of endosperm. They are coarser than cornmeal. Flaking grits are from 0.132 inch to 0.223, coarse grits 0.0512 to 0.797 inch, and regular grits from 0.0234 0.0512 inch. Cornmeal is from 0.0098 to 0.0234 inch. If you use degerminated cornmeal (not whole corn meal), this would work as well. The germ contains corn oil which could be a problem in head retention, although I believe Jack Schmidling has posted here success with using Corona milled whole corn. You do have boil either first to gelatinize the starch, and should use about 10% crushed malt with it to keep it from turning into a lump. You can add this "porridge" to the rest of the mash which is at a protein rest of 122F to boost it to saccharification temperature, although the temperature arrived at will depend on how much corn you use and may require adjustment. A much simpler way to use corn is to use brewer's flaked corn, which is made from passing wetted flaking grits through heated rollers. This gelatinizes the starches, eliminating the need for boiling them. This isn't commercially feasible due to their increased cost, but it is for homebrewers.

From: Jeff Renner <nerenner at umich.edu> Date: Sun, 22 Sep 96 22:18:22 -0400 Subject: Classic American Pilsner recognized! The style I proposed in HBD more than a year ago and in a Brewing Techniques article a year ago, Classic American Pilsner, made with 20-25% corn (and preferably 6-row malt) and hopped like a Continental Pilsener, has been added to the 1997 AHA style guidelines. It will be a substyle of classic Pilseners, with German and Bohemian Pilseners as the others. Thanks to James Spence at AHA and George Fix, Pete Garofalo and Del Lansing for helping make this come about. This style is really tasty - I like it better than Reinheitsgebot Pilseners, and so do many others. In blind tastings, where tasters haven't been told about the corn (which might prejudice them), it is immensely popular, even with homebrewers, according to George. I just served some to a friend who pronounced it the best beer she had ever tasted. So much for the mega-breweries idea that beer has to be tasteless to appeal to women. I hope many of you will brew it this winter and enter it in competitions in 1997. You'll like it! It's a part of our heritage.

Au contraire, mon frere! My ten gallon, 5mm thick aluminum pots cost about $80 with lids and shipping from a restaurant supply house, far less than ss. (And to head off a repeat of the aluminum thread, aluminum pots do not cause a higher level of aluminum in the wort, do not cause a metallic taste in beer, and do not cause Alzheimer's Disease. Anyone wanting to dispute this, please check the HBD archives where it has been beat to death.) Jeff Renner in Ann Arbor, Michigan c/o nerenner at umich.edu Return to table of contents
From: Aaron Sepanski <sepanska at it.uwp.edu> Date: Sun, 22 Sep 1996 22:14:36 -0500 (CDT) Subject: Waiting to pitch Just wanted to let everyone know about a recent mishap gone good, or OK actually. I recently made a batch of beer with a friend, same batch side by side, and it got so late that we didn't want to pitch until morning, which was in a few hours. We both agreeded that this would be fine. Well he had all the "beer" and stuff at his house, and had to go out of town and the drop of a dime. So we were unable to pitch until 3 nights later. I have often heard that you should pitch asap, to help the yeast out compete the bacteria in the beer. However, when racked of the sediment left over, there was no evidence of bacteria at all. No off flavor, and no evidence of "fermentation" by the bacteria. The wort tasted as good, clean, and sweet as when I poured it into the carboy. This proves that the wort was completely sterile at the time I put it in the carboy, and at the time I pitched. This also proves obviously, that it remained sterile while in the carboy those three nights. Thius all sewems to make sense in retrospect. There aren't many bacteria that can maitain life at boiling temperature (there are a few. There are bacteria that live in hot springs that have enzymes compatable to that temp.). These temperatures are to extreme for the proteins (enzymes) in the bacteria cell. This exactly why it is advantageous to cool the wort asap. As the temp lowers ther are more and more types of bacteria that can live in the wort. But chilling fast and racking into a sterile carboy, sealed by a sterile fermentation lock almost gaurantees success. Look at how many batches that we collectively have brewed without problems. Another key feature of the fermentation lock is that is contains water. Off hand, I can't think of many bacteria that are both aerial and aquatic, although I'm sure that there are some. This is another feature that helps keep the wrot bacteria free. I guess the point is.... Don't wait 3 days to pitch as I did. Pitching asap so the yeast can begin producing alcohol is sound advice. Unlike yeast, there are virtually no bacteria that are alcohol tolerant. Some strains can take some, but yest are comfortable all the way up to ~15% (yeast can produce more alcohol in a higher concentration than this). So this is really sound advice. But what I'm saying is don't neccesarily throw out your wort if you run into situations such as these. It worked out for us, so it's worth checking first. Some other key notes. All sterilization was done with bleach at a concentraion of about 10-15% Beer was stored in the dark at a standard room temperature of 70 +/- 2 degrees. Gravity= 1.061. Carboys were sealed with fermentaion locks filled with ordinary water. Thanks for taking the time to read this post. Aaron Sepanski P.S.

Howdy ya'll, While I was perusing the net this morning I came across an article concerning dwarf hops(http://www.breworld.com/the_brewer/9601/br4.html). This was apparently a professional paper aimed at the UK. However, I've been interested trying to grow my own hops, but unfortunately don't really have access to the height needed to grow regular hops. This article gave me hope though, stating that the optimum height for the dwarf hop varities is 8 ft. My fiance's sister has a fenced in(rectangular metal wire) yard and has been slowly growing traditional vines to attempt to cover it. Given the speed at which hops grow, she's agreeable to let me try using her yard for hops sometime. So, does anyone know if or where I could possibly purchase the rhizomes for the First Gold varity? This sounds like the best bet out of three mentioned in the article. Also if someone knows where I could actually get my hands on some of these hops to use in my brewing, I'd be really grateful! :> - -Chas (chas at crl.com) Return to table of contents

From: hadleyse at pweh.com ( 0 Hadley_Scott x5921 B-077 ) Date: Mon, 23 Sep 1996 12:16:05 -0400 Subject: No Sparge with Concentrated Wort Boil I've been very interested in the no sparge thread. I hope to try it in my next batch to save time without sacrificing quality. I'm also considering topping off the cool wort in the fermenter with cold dechlorinated water and ice cubes instead of adding water to the boiler before boiling the wort to reach the desired gravity. This would allow me to get the wort to a boil sooner and chill faster since there is less wort to go through my counter flow chiller. I've read somewhere that one thing you can do to improve the quality of your brew is to do a full wort boil but I'm not sure why. Would there be any sacrifice in the quality of the resulting brew because of the concentrated wort boil other than decreased hop utilization and an added risk of wort carmelization? I imagine appropriately increasing the hops and careful monitoring of the boil would solve those potential problems. Is there any reduction in the quality of the brew because of the addition of cold dechlorinated tap water and ice cubes to the already cool wort (less than 80 deg. F). Since the wort is already cool I wouldn't imagine HSA would be a problem. Thanks, Scott Hadley in Hartford CT Return to table of contents

From: Steve Stroud <strouds at cliffy.polaroid.com> Date: Mon, 23 Sep 1996 12:55:00 +0000 Subject: No-sparge and 'Yummy Malt Flavor' I have been using the no-sparge technique occasionally for the past few years (for special batches of beer). It is my experience that one extracts about 2/3 of the sugars from a mash by draining without sparging (assuming that Fix's basic procedure is followed). My yields have consistently been in the range of 20-21 pts/lb/gallon using this procedure. I echo Louis Bonham's comments about saving time and increasing the quality of a beer at the cost of a few $$ per batch. Steve Stroud strouds at polaroid.com BTW, I submitted George Fix's no-sparge essay to The Brewery's archive about six months ago. It can be found at: http://alpha.rollanet.org/library/YMltGF92.html Note that there are several numerical errors in the original version that Louis Bonham posted in HBD 2198. The most glaring is the grain bill for the experimental batch (# kg are incorrect). The numbers should read: > EXPERIMENTAL BATCH > Brew Size = 50 liters (13.2 gals.) > Grain Bill = 15.3 kg. pale malt (33.75 lbs.), 1.36 kg. crystal (3 lbs.) > Mash Water = 44 liters (11.6 gals.) > Water Directly Added to Kettle = 20 liters (5.3 gals.) > Vol. at the Start of Boil = 56 liters (14.8 gals.) > Starting Gravity = 1.060 (15 deg.

From: "Brian Thompson" <bthompson at mfi.com> Date: Mon, 23 Sep 96 11:34:29 PST Subject: Copper/Priming An observation and a quick question for the Digest: I find it hard to beleive that copper poses any real flavor problems for brewers (I suppose the health issues the FDA is looking into could be another story). Anchor Brewing Co. here in San Francisco has an all-copper set up (truly, a sight to behold) and I have never noticed a single off-flavor in any of their beers, and trust me, I have consumed a lot of their beers. A question: does the type of yeast used affect priming in any way? For example, will a lower-attenuating yeast provide less carbonation than a higher- attenuating yeast if the same amount of dextrose is added at bottling? Brian Thompson Return to table of contents

Hi all: Since my note to Shawn got an automated reply that didn't help me at all, and since no one else at AHA seems to want to answer the question, I'll pose it to the HBD collective: Does anyone know the location at date of the 1997 AHA Conference? I thought I read somewhere that it was going to be in Cleveland...Any help??? TIA Curt speaker at ehs.psu.edu Return to table of contents
From: jim.anderson at execnet.com (JIM ANDERSON) Date: Mon, 23 Sep 96 13:57:00 -0500 Subject: Dry-Hopping in Lagers Greetings, my Brewing Brethren and Sisthren: I'm wondering how long one should dry hop in lagers. (For those who maintain that this is inappropriate -- yeah, this is a pilsner -- I can only reply that I'm a hopeless hophead, and Saaz to me is as catnip is unto Tabby.) Is there a time beyond which utilization diminishes, or even produces adverse effects? What is "optimum?" I usually only dry hop 7-10 days, and I add my finings at the time of hopping. But then I'm usually in more of hurry, too. The current batch was brewed 8/17 and transferred to the secondary on 8/23. For the past two weeks it's been lagering at 33F, and I'm planning on giving it another month. Yeast is 2247 Danish Lager II.

From: cwynn at sawyer.ndak.net (Craig Wynn) Date: Mon, 23 Sep 1996 20:21:17 GMT Subject: 300 Gallon Kettle? I've been investigating the use of dairy equipment for constructing a micro brewery. I'm looking at a 300 gallon round freon dairy cooler. It was used to keep the milk cool until the creamery truck arrived at the farm. The cooling unit is only in the floor of the kettle. This is a double wall kettle with insulation in the side walls. The floor has a slight convex slope. You can see the circular pattern of the cooling tubes in the floor. Drainage is from a check/ball valve at floor level to the side of the kettle. What if....I connected low pressure steam to the cooling coil of this kettle. Do you think I could heat the wort to a boil and in a reasonable fame of time? According to the supplier who's a refigeration man the coils can tolerate up to 200 psi but the one I'm looking at generally runs at 120 psi. I think low pressure steam is only in the 15 psi range. Any thoughts you may have I'm sure I would benefit from. craig Return to table of contents
