Blind, Man of Vision) Subject: Brewing on Campus In hbd #1556, Eric Pendergras asks about the legality of brewing on college campuses, particularly in NC Well... I'm a RA in a dorm here at Georgia Tech, and I can tell you what I learned along the way. First off, your dorm room is where you live; you should be able to brew you 100gal/year quota with few gripes from the federal or state governments. Where you are going to run into problems is with the regulations put forth by your housing department. Here at Tech there are no specific rules against brewing. The tradition of brewing in the dorm goes back at least seven years, and no one thought anything about it until I asked my boss what he thought about these 'fermentation experiments.' He told me that anything I wanted to try was fine by him, as long as I saw clear to divert a six-pack his direction every now and then. Basically, as long as you follow any and all rules your school has about the storage and consumption of alcohol you're fine. In my case, I have to keep any and all beer in my room, I can only transport closed containers of beer, and I am personally responsible if any minors 'happen' to be drinking my beer, even if I'm not around. The only real problem I have is that I live and work in a freshman dorm, so I have to be especially carefull not to let them know quite what I'm doing. Over four hundred thirsty binge alcoholics would raid my room in a heartbeat if they knew what all the plastic and glass behind my couch was really all about. My advice is to talk to your RA or Community Advisor or Area Coordinator or whatever you have up there, and make sure they either give you the green light or agree to look the other way before you start.

I noticed this a while back. It seemed to me that it was not necessarily a product of the pot itself, but of whatever was on the stove surface before heating commenced. I traced mine to boil-overs of pasta (read: macaroni sans cheese) which stays transparent until a long cooking from reflected heat. You wipe up the spill, but you don't put the sponge down near the burner. These days my small brown crud is obscured by the large amounts of brown crud from boil-overs.

However, only recently have I decided to make some/all of the information I have gathered into one resource. Thus, I have created "Share your brew too!", a WWW server which will have just about everything ive ever see on the net related to beer. Food to go with it, entertainment, you name it, it WILL be there. Right now we are still under construction, and hope to have things finished by the end of October. (Or soon after) I have even come up with a few ideas of my own for the server. Currently we are *NOT* operating 24 hours, and are usualy operational during the daytime hours. If you are intrested in checking us out and you dont mind a little construction dust, please feel free to connect to us and check us out. Share your brew too! http://freak.ais.net/home.html Should you have any questions or comments before we go live, please feel free to send me email at rwmech at eagle.ais.net. I would love to hear from any of you who would have things to contribute, or even just your comments. Here is just a short list of things already being placed online. - Resources - Where to find what you want on the internet - Brew Share - My own personal Idea, check it out - Cats-Meow - The cat's meow, in a readable online format. - Food - Things to eat, or things to make with beer. - Entertainment - Things to do WITH your beer. - How to - Information for new homebrewers - Reviews - Reviews from readers like you - New daily postings of the HBD.

Date: Fri, 21 Oct 1994 8:08:30 -0400 (EDT) From: "Rick Gontarek, Ph.D." <GONTAREK at FCRFV1.NCIFCRF.GOV> Subject: Genetically altered yeast/zapap modifications Hello everyone. I read an interesting article in "The Journal of NIH Research" (Oct. 1994, Vol.6, p.43) about genetically altered yeast. To paraphrapse, it seems that research groups in Japan and Germany have added a gene from Acetobacter bacteria to a strain of brewer's yeast used in fermenting beer. This allowed the altered yeast to enzymatically eliminate acetolactate, which if allowed to remain, will become diacetyl (giving the beer the undesirable "butterscotch- like" off-flavors). A Japanese researcher claims that Japanese brewers must "cure" their beer for six weeks in order to allow the yeast to slowly absorb the diacetyl, converting it gradually to acetoin,which doesn't affect the taste of the beer. The bacterial gene encodes the enzyme ALDC (acetolactate decarboxylase), which concerts acetolactate directly to acetoin, bypassing the bad-tasting diacetyl and effectively eliminating the six-week delay caused by the need for curing. Both groups presented data at a meeting showing that the levels of diacetyl were significantly reduced in beer fermented by the altered strain compared with the concentrations found in traditional yeast, while all other measurements (including, fortunately, ethanol production) were unchanged. The article does also say that Germans are reluctant to use genetically-altered yeast in their beer. Anyway, I thought that some of you might be interested in this tidbit. On another note, in the past I have seen discussion about Zapap lauter-tun modifications that can be employed to result in better extraction efficiency. I am sad/embarassed to say that I blew past that discussion (must've read the Digest before my morning coffee). So I was hoping that some helpful soul would coach me as to improve my Zapap design. I know that insulation would help. But what else can I do? TIA for all help. On yet another note, I don't mean to open a can of worms with this, but I was talking with the owner of a local homebrew supply shop a few weeks ago. He has been trying to get a small microbrewery going for a couple of years now, so he's had frank discussions with many other microbrewery owners. He said to me that many (most) micros don't use a real lager yeast to make their lagers, but rather simply use ale strains fermented at slightly lower temperatures and then age the beer cold for a few days. The reasoning behind this is simple: time is money, and if a lager sits in cold fermentation for several weeks, then that beer is taking up valuable space in the brewery. It all boils down to turnaround time, which = $$$. I was shocked. Has anybody heard of this. I'm certain that if asked, most microbreweries would not admit this, but if it is true, then I feel duped! Anyway, I thought it was interesting enough to bring up on this forum. Well, I must get back to work. Have a chilly one for me!!

Date: Fri, 21 Oct 1994 08:45:24 +0500 From: gheiler at Kodak.COM (Greg Heiler) Subject: hop quality/dry hop Recently made my first batch of Alt beer which required 16 HBU worth of Northern Brewer. I ordered the hops by the ounce and they came in with an AA of 5.3! All references I have say the AA should be 7-8. The references also talk about poor stability and rapid AA degradation. I called and double checked with the supplier and the rating was confirmed, however no retesting was done. Compensated for thr low AA by adding more. Interested in info on hop stability and wonder if the low rating was a result of poor/long storage. The batch is 2 weeks old now and I have percieved an off bitterness in the aftertaste. Bad hops or needs more conditioning? Unfortunately, I don't have the expertise yet to make a judgement, by taste, on the mislabelling possibility. I have been chain brewing and I dry hopped my second batch with hop plugs. First I had to cut them in half to get them in the carboy and then they worked great. They all floated on top and I racked after 4 days. I had the racking tube right to the bottom and racked with no leafs getting into the priming bucket. The leafs collected around the siphon but did not enter the tube. Return to table of contents

In some breweries the chillers used are in fact very similar to the CF types used at home with 2 important differences. First the wort to coolant contact area is much greater, second the coolant used is usually Glycol which has a greater heat transfer rate. Kind of imagine your pipe in a hose version except about 300 feet long. Pump the wort through that using extremely cold water to chill and you can cool 250 gallons about as fast as it takes to pass it through the chiller. I do 70 Liters through a 2' by 3' glycol plate CF chiller in about 3 minutes dropping from ~212F to 60F. ....Glenn Glenn Anderson Manager, Telecommunications Facilities, BCS Sun Life Of Canada GRAMPS at INTERLOG.COM Return to table of contents
Date: Fri, 21 Oct 94 09:55:01 EDT From: Spencer.W.Thomas at med.umich.edu Subject: Re: Sub-Standard Hops? Mittelfrueh is the classic Hallertauer hop. "Hallertauer" must means "grown in the Hallertau region". Thus, "Hallertau Hersbrucker" is the Hersbrucker variety, grown in the Hallertau region. Hallertauer Mittelfrueh is one of the three "noble" hop varieties, although the Germans would like to convince us that Hersbrucker is just as good. Apparently Mittelfrueh is hard to grow, or is blight-prone, or something. Return to table of contents

(And > somebody is getting pretty pissed about it happening over and over and > over.) It's probably just the intensity of high heat reflected off the bottom of the large pot. One thing that's very important is make sure that your stove top is *very* clean before you start. Any grunge that's already on the stove top will turn brown/black and get very nasty from the high heat. Once you've got the stove top clean, try covering it with a couple of layers of aluminum foil, shiny side up. I've had little if any problems with stove discoloration since I started doing this. ============================================================= Hal Laurent | Home: laurent at charm.net Baltimore Maryland USA | Work: laurent at tamrc.enet.dec.com Return to table of contents

Menegoni" <lmenegoni at nectech.com>, on 10/21/94 9:44 AM: The most common method I have observed is by using a heat exchanger. The heat exchanger is a device that is made from a good thermal conductor and has a high surface area to volume ratio. I have seen water cooled heat exchangers at micros where the cooling process is used as a means of preheating the mash water for subsequent batches. Return to table of contents

Date: 21 Oct 1994 10:10:40 -0400 From: George Kavanagh O/o <George.Kavanagh at omail.wang.com> Subject: Slotted Ring Redux I expect that a slotted ring _will_ clog if used to filter out hop gunk after the boil as reported by rlarsen at free.org in HBD 1558. I use the Slotted Ring <design by tkavanag at ucs.indiana.edu> setup not to filter hops, but as a sparging device after mashing (instead of a false bottom getup). The mash pot becomes the lauter tun! It works quite well as a sparger. My (slightly modified ) setup incorporates several sections of bent and slotted copper tubeing that make the ring, connected with finger-tight compression fittings, and a "standpipe" from the ring to the inside lip of the kettle, then a compression coupler to a large inverted "J" shaped piece of copper tube that bends over the lip of the kettle and ends below the level of the bottom of the kettle. I use this setup inside an insulated box, made to fit the kettle, and set on the edge of the counter, so that the long end of the "J" tube extends below the counter top. A 1/4 turn ball valve to meter the flow is on the end of the "J" tube, with a short piece of copper tube after the valve, then a length of plastic tubeing to the collecting vessel. I use a single "J" section extending below the bottom of the ketttle because I had previously had trouble with lost siphon due to air leaks at the several finger tight compression fittings I had been using in a multi-part "J" tube. Situating the valve below the level of the kettle guarantees a good head for the siphon. The ball valve can be adjusted quite finely; I had no trouble getting a 3 hour sparge on the first run. ( 33+ p/lb/gal !! ) Timely infusions of 170 degree water and the insulated box keep the mash properly warm. -gk ( George.Kavanagh at omail.wang.com ) Return to table of contents

It is often sold as "Hallertau" or "Hallertauer". Hersbrucker is a similar variety from the same region. If homebrew shops would properly label their hops "Hallertauer Mittelfrueh" or "Hallertauer Hersbrucker", etc. we might know more about what we're getting.

At 75 deg F the saturation pressure of CO2 is 905.1 psi, i.e., at >this temperature and pressure CO2 is 100% liquid. 905 psi is the "saturated vapor pressure" of CO2 liquid at 75F. This means that in a bottle at this temperature containing nothing but C02 (i.e. the vapor is pure CO2) the liquid and gas phases coexist. BOTH are present. It's just like your pressure cooker after the air has been vented. The sturated vapor pressure for water is 15 psig (roughly) at about 251F. Water and steam coexist at this pressure/temperature combination >That's a higher pressure >than the tanks are normally filled to. Usually, at 75 degrees F the tanks >are filled to 790 psi. (Actually when the tanks are filled the temperature >is around 0 degrees F which corresponds to a pressure right around 300 psi). >Anyway, it's possible that the tank is in the middle of a phase change (going >from liqid to gas). Cylinders are not filled to a pressure: "Cylinder filling is usually accomplished by pumping liquid carbon dioxide into the cylinder to the desired net weight" (CGA G-6, see below). "The weight of carbon dioxide must not excede 68% of the weight of water the cylinder will hold at 60F.." (idem). When home brewers take their tanks for refil it is usually done by transfer from a syphon bottle at room temperature. The bottles are connected by hose and the valves opened. Liquid flows from the syphon to the other bottle until the pressures are equalized between the two and the valves shut off. The amount of gas transferrred is typically 3 - 4 pounds (5 pound bottle). Chilling the bottle before hand will allow more liquid to transfer. Don't go to the welding store, buy a syphon bottle and try this yourself unless you know what you are doing. There's more to it than I've set out here and it is quite possible to excede the 68% limitation (especially if you chill the bottle) with possible diastrous consequences. >So, Neon, it's possible that you can have some liquid. Especially if your >tanks are fresh and cool. If room temperature is.. and the gauge reads.. 50F 638 60 753 70 838 80 954 87.9 1056 ..then there IS liquid in the tank. As you draw off gas, the liquid boils to maintain the equilibrium. When all the liquid is boiled off the pressure reading goes down as the remaining gas is drawn off. Thus the gauge does not indicate the amount of CO2 remaining until the tank is almost empty (just like the gas guage in your car) Liquid CO2 CAN NOT exist at temperatures above 87.9F (the critical temperature). Above this temperature the pressure IS indicative of the amount of gas in the bottle. People really interested in understanding this subject and the correct handling of CO2 should obtain Publications CGA G-6 ("Carbon Dioxide") and G-6.3 ("Carbon Dioxide Cylinder Filling and Handling Procedures for Beverage Plants") from the Compressed Gas Association, 1235 Jefferson Davis Highway, Arlington VA 22202. Be prepared for a bit of a shock when you hear the prices, though. Also note that G-6.3 is currently out of stock and is being reprinted. Lisoi! A.J. Return to table of contents

At that time, one can have some of their fresh brewed beers. Much of their beer is still contracted out to the Pittsburgh Brewing Company, the makers of the appropriately named Iron City Beer (it tastes like steel), and the very watery Iron City Light.

YMMV. > Given that this is apparently *my* idea being bandied about, I rush to my own defense: Firstly, I am not responsible for a "slotted-ring" idea. I specifically recommended using the smallest possible bit and drilling teeny, tiny holes in the under-surface of the loop. This is critical to the concept, and slots suck. So, I suspect, do big holes. The entire point of this system is to whirlpool the hops and break into a big heap *inside* the perimeter of the loop, and then to have holes that allow the passage of liquid, but are too small to suck in hops. It works like a charm with pellets. Really. I have no idea whether Rich used little holes or tried to short-cut the idea. There is also a difference in procedure, which may or may not have an effect. I use a counter-flow wort chiller, so the wort going into the siphon is hot. ?? Next question: did Rich allow the vortex to settle before attempting to draw off the wort? I've found that it takes about 20 minutes of settling time for the mountain to form. It's also important not to jostle the kettle during siphoning or the mountain can collapse. - --Jeff PS.

Many of you will know me from my involvement in this forum and for my agitation for suffrage in the AHA. What some of you may not know is that I have in the past put forward to the AHA proposals for creating a democratically elected Board of Advisors which is *truly* empowered to oversee the creation and implementation of member based policy (Beer Judge Certification Program, National Homebrew Competition, Conference Content Committee, Club Services, etc...) and is directly accountable to the members through an election process. To date my efforts have met with staunch resistance and I have even been told that "the members aren't interested." Since I have heard many rumblings recently I am at this time seeking to identify like minded individuals who are interested and willing to petition the AHA to advance the cause of some level of empowered direct representation of the "membership" at the policy making level.

I have the same problem, and the solution is to clean the stove before you brew. I mean clean it REALLY well. I don't know about yours, but our stove always has a little gunk on the top, even after a light cleaning. That is the stuff that is turning brown and burning on top of the stove. If you spend 15 minutes and clean it well with a couple different types of cleaners (Do Not mix the cleaners!!! clean once, dry, repeat with different cleaner) the problem will be greatly reduced. The only problem is if you clean it too well so there is nothing to burn on, the beer gods get mad and they will cause a boilover. Now our stove top is brushed stainless, so I just let it burn on, and hit it up with an SOS later. I now know why commercial kitchens are all SS. The other option is to not cook any greasy food on or around the stove. That will make it a lot easier to clean. - -- Gordon Baldwin gbaldw at usin.com Olympia Washington Return to table of contents

Yes, it uses lots of water, but the cooling water (that becomes hot) is then used to fill their hot-liquor tank for the next days brew. I think some of the hot water is also piped to the barreling section and used for the cleaning of the barrels. Cheers, Brian Return to table of contents
Date: Fri, 21 Oct 94 08:58:11 PDT From: hollen at megatek.com (Dion Hollenbeck) Subject: Yeast Starter and Agar Recipes I am just getting into yeast propagation and after reading every available piece of info on the subject, have come up with conflicting recipes for starter wort and agar. One book suggests very low gravity wort about 1.010, another recipe comes about 1.020 and the Yeast FAQ suggests to use wort about the same as the beer you will be brewing, which comes out to 1.040 or above. The Yeast FAQ does not suggest use of any yeast nutrients, but *all* of the other sources do. Only one source gives an amount of yeast nutrient and that is 1/16 tsp per cup of wort. All the other books come from yeast propagation kits and they of course want you to buy their pre-packaged wort mixtures which of course they will not state the recipe for. Pretty much the same for agar recipes. Only one book and the FAQ give a recipe. The book says to use yeast nutrient as well as malt extract, the FAQ, just extract. One source which provides agar does not say to use any malt extract, just agar and water. Another "kit" source provides premade slants and plates and these definitely look like they have malt extract in them Can people please comment on recipes which they use which are successful and why you do or do not use yeast nutrient in either your starter medium or agar?

What my local microbrewery does, as well as several others here in San Diego is to use a counterflow chiller with two loops. The first loop in the chiller is water. The second is glycol at near freezing. In many micros, the water is pumped through the chiller and into the sparge water tank for holding until the next day's brew when it is used to heat up as mash water. In this manner, a large portion of the heat extracted from Tuesday's chilling can be used for heating mash water for Wednesday's brewing. Also, there is a ball lock fitting on the chiller which is hooked up to a cylinder of medical oxygen for aeration during chilling. dion Dion Hollenbeck (619)675-4000x2814 Email: hollen at megatek.com Staff Software Engineer Megatek Corporation, San Diego, California Return to table of contents

Solution? I used to have this same problem. My water is from a private well, and is high in carbonates. I have to pre-boil my sparge water, and ended up with the same kind of stains when I did it on the stove. The heat from the burner evaporated water that had dripped onto the stovetop, then baked the minerals right in. I found that covering the stovetop with heavy duty tinfoil helped prevent the stains. To remove them, apply a paste of warm water and baking soda, let it sit for a while, then use a plastic abrasive pad. I recently got a three tier gravity fed system going (thanks, Mac!), all my brewing is now done in the garage, so my wife is of the formerly pissed-off variety. :-) *********************************** JC Ferguson asks: >those who dry-hop in the keg: is it ok to leave the hops in the keg for >up to 1-2 months? or, should they be removed after a few weeks? My experience has been that after about 2 weeks or so, the beers I've dryhopped this way develop a faint vegatative flavor, they start to taste the way freshly mown grass smells. What I do now is add the hops at kegging time, put the keg in the fridge at 40F for a week, and keep 30 psi on it. After a week, I attach a picnic tap, draw off a pint or so which is mostly sediment, then transfer the beer under pressure to another chilled keg. One week is enough time to develop the hop nose, and to carbonate/clarify the beer. *********************************** My .02 worth on the hop form factor thread. I buy my hops several pounds at a time, and get both a price break and a break on the shipping. I use pellets for pretty much the same reason Tony Verhulst does, I store them in the food freezer, so space is an important consideration (see pissed-off wife reference above). For dry-hopping, I do use plugs and occasionally whole hops, when generously donated by my brewing buddies who grow them. IMHO, the aromatic qualities of plugs and whole hops are better than pellets, and they are more easily retained in a nylon hop bag. I store all my hops in mason jars that have been purged with CO2.

My question is what is the best way to get whole hops into a 5 gallon carboy? It was tough enough getting the loose cones in, but I have also read that some people put them in a bag. For those of you who do this, do you use a different style of fermenter? I can't imagine getting a bag full of hops through the neck of my carboy. Thanks in advance for any advice.

Someone big must have been using them for a while. Given the puny number of small breweries in the mid-70s and early-80s when Anchor and SN built beers with cascade it seems some "big guy" must have wanted cascades for something. Why would they have been cultivated otherwise? ______________________________________________________________________ Erik A.

THese are cooling fins much like a car radiator. Usually the coolant is either chilled water or chilled glycol. Many systems employ a two stage chiller, the first stage uses city water to cool wort to city water temps (the warm discharge water is fed back into a liquor tank or kettle for the next dough in), the second stage is smaller but often uses chilled glycol. jc asks: > those who dry-hop in the keg: is it ok to leave the hops in the keg for > up to 1-2 months? or, should they be removed after a few weeks? Yup, no problemo. I use this method with some barley Wines that can sit in the my keg for up to a year before I get around to tapping and/or killing it. steve writes: > Subject: Cascades and the mega-brewers > > A friend of mine works for a major US hop broker and importer.

What do you know! 9 hops varieties, including cascades and still less than 15 IBUs and no hop character!

I would also like to plug yet again the wonderful character that Styrian Goldings imparts. This is rapidly becoming one of my favorite aroma/flavor hops (Im still a cascade/centennial freak, but EKGs and SGs are really great hops too). > I looked through all of my books and was unable to find a reference for > the Mittelfrueh variety of Hallertau.

As big as Anchor, Sierra and Red Hook are, I still put them in the large craft brewery area, for now at least. Hopefully in a few more years we can call brewers like Sierra "big boys". Barry writes: > Doth mine eyes deceive me? Looking through BT vol 2 no 3, I saw an ad > for US Wholesale Homebrew Supply Co. $3.85 for a *LB* of Cascade? Yup ,its true, although a very rare price to be offered to direct sales customers. I have a micro friend who can get Cascades at $1.50 a pound! I suppose this is how US Wholesale can do it and still make a profit. Just goes to show how much money can be made along the way in the homebrew market if you know how to do it..

Just another comment on Briess Victory malt. I was amazed at how tasty of a beer can be made using 6 row Victory malt from Briess. My friends at Old Dominion Brewing Co in Ashburn Va used it as the base malt for thier latest Octoberfest. This Ofest has to be one of the finest examples of domestically produced Ofest using domestic malts. It imparts a wonderful malty, toasty character that blends perfectly with the other specialty malts and hops in the this beer. If you find it in the DC area before its all gone, grab some, I doubt you will be disappointed. Jim Busch Return to table of contents
