Isn't making your own great beer what homebrewing is >all about? For developing ones brewing skills, I think a stronger argument can be made that cloning is far more effective than brewing to style guidelines. Find a beer with qualities that you really want in your own beers. Get all the information you can about how this beer is brewed, including other brewers recipes. When youve brewed your clone, you get to do a direct taste test comparison with a bottle of the goal beer. Isnt learning to make great beer what homebrewing is all about? Ed goes on: >for those of you out there that want to clone >Sierra Nevada Pale ale for instance, why don't you try to figure >out what it is that makes you like SNPA more than other pale >ales? By golly, bet thats exactly what those low-life cloners thought they were doing. Cheers! Steve sdginc at prodigy.com Return to table of contents
From: Dale Smith <des at io.com> Date: Fri, 11 Oct 1996 13:31:11 -0500 Subject: Mocha Java? I recently had a Red Hook Double Black Stout made with Starbuck's (TM) coffee. I really enjoyed it. I have been toying with the idea of brewing a Mocha Java Porter or Stout which would be bittered with unsweetened chocolate and "dry hopped" with black coffee. Any idea about this? Anybody got an all grain recipe that they've actually brewed and like? I'd prefer something that could be ready by Christmas and wouldn't need to age for months.

Any comments would be >appreciated. > >Name: Wit Christmas O.G.: 1.049 Hi, John. Your wit recipe is going to have the wrong hops for bitter and flavor. Use a low alpha noble hop like Tetnang. High alpha hops are OK in high gravity beers but will be way out of place in a delicate wit. Cascade is OK if used for bittering, but not for flavor. As you said, there should be a noble flavor, not American. So cut out the Cascade. There should be little to no hop aroma in a wit so cut out the 15 min and 0 min addition of Szaaz. I use Szaaz flowers at 60 min and 20 min. Hoegaarden is better yeast than Wyeast. BrewTek's is the best. It tastes like Celis and you can bottle a week after pitching. Yeast Lab has a good culture as well. The coriander in secondary is very important. I'm glad you have it there. You mentioned that curacao adds citrus notes. I assume you are referring to the dried peel and not the liquor. It actually adds bitternes and not citrus. The citrus comes from the yeast. You are going to need 88% lactic acid when you bottle to adjust down the pH. Do it by taste instead of a meter or paper. I think Celis is 4.3 but when I went by that, it was too acidic. In any event, you will have a beer much better than the insipid Blue Moon or Wit! - --- Kit Anderson Bath, Maine <kit at maine.com> The Maine Beer Page http://www.maine.com/brew Return to table of contents

From: Eugene Sonn <eugene at dreamscape.com> Date: Fri, 11 Oct 1996 16:15:55 -0400 (EDT) Subject: extreme beers Hello HBD, George Piro mentions that he doesn't think there are good USA examples of Alt Bier because the true style is "extreme" and not very marketable. I would agree, but think it's a more general phenomena. Remember the thread about Marzen/Octoberfest? Most of the commercially available ones are not textbook examples of that style. Most commercial brews (except for limited-run beers) are meant to appeal to the general consumer. That's ok because if you like the "watered-down" version. You may look for a more true-to-style version of the beer. For me, homebrewing has it's major appeal because I can tinker with my beers until I have them exactly how I like them. Yes there are pockets of the country where super-hopped beers are the norm and yes there are places where you can get good true-to-style beers, but when was the last time you had an Eisbock at a bar in the U.S.? This whole post may be a showcase of stating the obvious, but I would appreciate if the postings on the HBD would just accept these beers for what they are......a way for people to ease into a new beer style. Maybe when we have as many breweries as there were before prohibition there could be a real market for these true-to-style beers.

Went to my local hb store and talked to one of the employees there re: the types of malts they carried in bulk. I was interested in Hugh Baird in particular (2 row). He said he carried it, but also carried a UK brand called "crisp" . He felt it had a little more character than HB malt. I have never seen it discussed on the digest. Anyone know about this stuff?

From: Paul Sovcik <U18183 at UICVM.UIC.EDU> Date: Fri, 11 Oct 96 15:27:11 CDT Subject: Beans and beer? The other night, after making a huge crockpot full of pinto beans and realizing that there was no way on Gods green earth I and my family could eat all these things before they spoil, and the last thing I'd ever do would be to give them to the dog, and just how DO six cups of dry beans turn into a full week of meals.... That I wondered about the potential for using beans as an adjunct in beer. I know dry beans tend to be very high in protein, and they are low in fat. I'm not sure about carbohydrate content though. Are these things pure protein? Has anyone ever investigated the potential for using pinto or navy or kidney or garbanzo beans as an adjunct? Delano? How would you mash them? - -Paul Paul Sovcik, Western Springs, IL Return to table of contents

I for one, though being new to the "addiction" (hobby just does't do justice), have never used a recipe I didn't adjust, mess in, or create on my own. Several people in many diffent threads have discussed AHA Style guidelines. WHere can I find these. Are they on-line buried somewhere in the massive depths of "The Brewery" web site? If they are available would someone be so kind as to tell me where? Thanks, Sincerely, Phil Wilcox ps.

From: "Brian Thompson" <bthompson at mfi.com> Date: Fri, 11 Oct 96 10:00:54 PST Subject: Pilsner Urquell Sorry this is so late on the thread (it takes a long time to catch up on HBD reading once you get behind), but I thought I'd toss my two cents in. Back in the summer of '91, I happened to be traveling in Europe and spent a few days in Czechoslovakia. The country at that time was still very much recovering from communism and prices reflected that. My friend and I managed to pick up a case of Prazdroj (as PU is known in CZ) for the paltry sum of $3.50. We're talking 12 half liter bottles for what we pay for a pint here. I thought I was in heaven. I'd never tasted PU before that day and I swore if I had my way I'd never drink another Budmilloors again. Well, I got back to America and found a few places that imported PU (it's much more available today) but was shocked at the poor quality of every single bottle I tried. The moral of the story? I don't drink PU in America, to this day I haven't had an un-skunked bottle. But by God, if you get the chance to try it fresh, you will know the meaning of religious experience. I was again in Prague about two years ago and made an effort to try other Czech beers: Staropramen and Budvar are as good, if not better, than PU. For those of you living in the Bay Area, Toronado in SF has Staropramen on tap, haven't been to try it yet, but if it's half as good as it can be, it's worth checking out.

From: layton at sh28.dseg.ti.com (Jim Layton 952-3733) Date: Fri, 11 Oct 1996 17:51:28 -0500 Subject: Alt in the USA OK, I'll chime in. Hannen Alt is available in the Dallas, Texas area. It is the only alt imported from Germany that I have seen in this area. I bought a bottle two weeks ago to use as a standard in evaluating an alt which I recently brewed. The label indicated the location of the brewery, but it wasn't Dusseldorf. I won't bore you with the several ways in which my homebrew missed the mark, but I will use these observations in adjusting my next attempt at an altbier: Color - Pretty dark but quite clear. Like a dark Oktoberfest. Malt - Toasted malt flavor, more intensely toasty than Spaten or Paulaner Oktoberfest. Might have used a darker grade of munich malt than I can get around here. The finish was dry. Hops - Fairly bitter, very little hop flavor. More balanced in bitter/ sweet than I had expected from some descriptions of the style (The AHA guidelines show a pretty wide range for IBUs). No hop aroma to my nose. Esters - Won't mistake this for a lager, but it was a pretty clean brew. A clean ale flavor. Overall - Like a dark Oktoberfest brewed with an ale yeast and a bit more hops. Very tasty, but I think the specimen I had may have lost something due to age or pasteurization. The malt flavor was just a little less fresh than it might have been. I won't claim that Hannen makes the definitive altbier, but this was good. A homebrewed version could be better! Jim Layton layton at sh28.dseg.ti.com Return to table of contents
From: Jim Busch <busch at eosdev2.gsfc.nasa.gov> Date: Fri, 11 Oct 1996 18:30:17 -0400 (EDT) Subject: HopDevil, cont. Tom inquires: <The recent thread on the IPA style and the high praise for HopDevil from <Victory Brewing, has prompted me to try my hand at a "Classic IPA," I would first refer all interested parties to the excellent piece written by David Brockington on American IPAs in the current issue of Brewing Techniques (where you can also read some of my drivel, ;-) Note we are talking about American IPAs now. British IPAs no longer exist, by and large. They are merely versions of Bitter. The debate rages, tradition, history, color, hop types, etc. I say tradition is great and very important but we in the US craft brewing industry are expanding and redefining styles all of the time. I didnt go about brewing HopDevil's precursors with the idea that I had to mimic some historical IPA recipe. I made what I liked, using hops that I find pleasing and yes, even using that horrific bland American Ale yeast! I was inspired by Celebration Ale, a beer Ive always had a love for, but I never tried nor accomplished imitating SNCA. While HopDevil is darker than most IPAs it is in range with many hoppy American ales being brewed today. I dont find color or malt foundation to be a defect with American IPAs but I think they bring complexity to the brew that would not exist with a grist predominantly based on pale and Munich malts. The one aspect we all agree on is a heavy obvious hop bittering foundation. <My request is for hopping info for a classic IPA. Classic, historical IPAs should be crafted in the veins of Brooklyns IPA. Light in color and based on UK hops. OG 16P, FG 3P or less, IBUs 55-70, good aroma presence. <It sounds as if HopDevil is being nominated for the definitive IPA (I can <forgive you for using cascades). Can you provide me with insight, Jim? <Any trade secrets that Victory is willing to part with? ;^) The general overview of the beer can be found in Daves article. Cascades provide the late aroma additions while Centennials and some domestic Tettnang are used in the kettle. Aim for about 50 IBUs from the first Centennial addition to provide the hop foundation and use additional hops to taste for mid and late additions. Our grist is based on German malts, imported pale malt, Vienna malt, Munich malt and caramel malts. Brewing Techniques is a great magazine and I encourage all interested readers to go get it and see what Dave has to say. We dont agree on all things stylistically but I think I agree more with what Dave has to say on styles than on any other widely published source. Prost!

I know that it's dry hopped with cascades (I can read the label). But I don't know nearly enough about beer or homebrewing to be able to discern exactly what other ingredients are used or the methods Anchor uses to make such a great beer. I'm sure this will come with more experience, (I've only brewed 8 batches so far) but until then this is a way that I can start with a recipe that is _SUPPOSE_ to taste like a target commercial beer, and then compare it with what I get myself. > For me, the style is the key.

From: texan at mindspring.com (James and Tamara Williams) Date: Fri, 11 Oct 1996 20:39:09 -0400 Subject: IPA It's ironic that the subject of whether Bass is an IPA came up just now since a friend and I were discussing that very topic last weekend. I said I don't think it tastes like an IPA, but then he raised an interesting point. The original reason an IPA was brewed to such a high gravity and hopped so aggressively was to survive the long boat trip to India from England. he said: During the long trip (several months) and as the beer matured the perceived hop level and body would continue to decrease until it arrived in India will a more traditional hop flavor and mouth feel. So is the definative flavor of an IPA deteremined when it was first put in the cask or after it arrived and tapped? Comments? Brew on, James Return to table of contents

Copper is an excellent conductor of heat ( a must for direct firing), malleable and available. Tradition is strong in the artsy trades like wine and beer because small things like copper in beer, oak tannins and slow oxidation of wine, etc.,(just like your mother's cooking is the best in the world) are very important if not completely understood. I have looked into some of these modern brew kettles and never seen a piece of copper. Where is it? I don't doubt you, just would like to know more about it. - --------------------------------------------------------------------- From: Ken Sullivan <kj at nts.gssc.com> And... what is couscous anyway? I asked around the office and got answers from 'pasta' to Morroccan Wheat. Can it be mashed? You can mash anything, it just depends on the size of your hammer. Cous Cous is the name of the dish which can be a very spicy. In North Africa it is generally a thin tomato or ( mutton or goat) meat gravy over a starchy preparation which is made is made from Bulghur ( or Bulgur) Wheat . The wheat is cracked. steamed, dried, packaged and sold. Bulgur is essentially instant wheat granules ( about the size of the little seed shaped pasta - Semillas ), Just add boiling water and wait a few minutes. I know the box which contains the wheat grains says "Cous Cous" and sometimes "Pasta" to describe the contents., but this is a marketing gimmick. If it said Bulghur Wheat would you know what to do with it and buy it? I believe the grains are called Bulgur. Bulgur is Turkish and makes me guess this preparation is left over from the Ottoman Empire. Any Moroccans or Libyans out there who can comment further? Bulghur should mash just fine in a mash containing 2 row or six row pale malt. Be sure to use a protein rest. - ---------------------------------------------------------------------------- Saying "Pale Malt" reminds me. I looked through lots of professional books, semi-professional, and hobby books. I find that depending upon the author and his subject. "Pale" can be used for Pale Ale or for Pale lager/pilsner. One of the authors ( born in Wales and lived in the US for lotsa years), writing about British beers used the phrase interchangably saying pale sometimes and pale ale others. I find that when a book contains both Lager and British beers discussions, "Pale Ale" is used for British beers and "Pale" or "Lager" is used for American and European lagers. This is done to avoid confusion. I suggest we try to be more consistent and do this. AlK is righter on this usage than I am on a global basis. In the US, because we use both lager and British Pale malts we tend toward the Continental usage of Pale, I find "pale" means lager or pilsner malts almost always and Pale Ale refers to highly modified malts in the British fashion. I guess we should stop saying "Pale" by itself and say lager or pilsner or "Pale Ale". I do know this. LOTS of people have been confused by the use of Pale to mean both lager and british malts. - ------------------------------------------------------------------------------ Peter Ensminger says: "Sparge water pH is important. If it is too high, it will extract polyphenols (tannins) from the grains into the wort and this can lead to an astringent beer. One way to lower the sparge water pH is to add gypsum (CaSO4.2H2O). However, for water which is highly alkaline to begin with, you may need to use lactic acid or phosphoric acid." In pure distilled water, CaSO4 will be nearly neutral and will not acidify water. If the wort exiting from the sparged grains has phosphoric acid or the higher protonated forms of the phosphate ion then calcium phosphate precipitate will release the protons from the phosphate ion which will acidify the wort. But as the sparge becomes more dilute in wort components, the phosphates decrease ( which is one reason why the pH goes up) and the ability of calcium sulfate to acidify the sparge decreases. Therefore, I would not recommend calcium sulfate as an addditive to the sparge water. Use lactic or phosphoric acid in all cases to be safe. - ---------------------------------------------------------------------------- Rick Dial has an interesting idea to avoid copper contacting the hot wort during the cooling phase. "My solution seems very simple and as such must have some serious drawbacks. Silver solder 10-15 wraps of 1/2 " copper tubing on the outside of my 15 gallon stainless brew kettle. Run the tubing dry during the boil. Blast cold water around the outside afterwards and have no concerns about copper flavors or gunk in the counterflow chiller. Will silver solder bond correctly to the stainless? Will the cooling rate be significantly slower then with my counterflow chiller? " 1) A problem I see is that the surface area exposed to the hot stuff ( the boiler wall in this case) is substantially less than what you would have if the copper tubing were inside or the wort was runnung down the middle of the tubing.. Heat transfer is surface area dependent so I guess you will have either cooler water running out the exit ( poor heat transfer efficiency) or it will take maybe several hours to cool it off, based on a comment some weeks ago that a coil in a boiler takes about 1/2 hour to cool to RT.. 2) Copper and SS have a different thermal expansion coefficients and you may have separation or minicracks develop which can impede heat transfer. It will unlikely be a problem over this small temperature range with the thin SS and malleable copper. 3) I believe silver solder will adhere to both SS and copper ( based on I think I remember doing it many years ago - but I am suspicious), but to those who have done it recently, please comment. Why not try a crude test and see if the tubing wrapped around the kettle without soldering will give you some cooling. This will be the worst rate of cooling you get since you will not have good contact. One solution to this surface area contact problem may be to put your kettle in a thermal transfer fluid - like water. Having direct contact is not really a problem and you will still have efficient cooling. Try your setup without soldering, in a waterbath. Please let us know. - ---------------------------------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3203 at compuserve.com Return to table of contents

The radio stations here even carry hourly corn prices! Corn these days is highly hybridized (and even genetically engineered to be resistant to fungus). Besides specialty corn there are two basic varities: - Eating corn = sweet corn (white or yellow?) - Feed corn - (misnomer) - used for both feed AND corn starch & corn sugar, major ingredients in most human foods these days - there was an excellent National Geographic article on this a couple of years ago - highly recommended. There are significant sugar differences between the types of corn. Anyone who has tried feed corn will tell you it doesn't taste very good - not sweet. Specialty corn would most definatley include blue corn. Anyone that has had blue tortilla chips (or posole') will not ever again confuse blue corn's taste with the regular variety. And let's not forget popcorn as well - which I've seen in colors other than pure white. All this reminds me of barley malts. Yes, there are differences! Should it be any surprise that corn can be as different as barley? Return to table of contents

Also if anyone can send me *any* information on this hop(oils, flavors, what hops it can reply/most resembles, etc), I'd greatly appreciate it. - -Chas (chas at crl.com) Return to table of contents

One of the best things about our forum is the ability to discuss ideas and concepts and topics on a regional basis. GO HBD GO! That said, here's my .02 on IPA. An excellent couple of articles on IPA were written by Thom Thomlinson in Brewing Techniques starting with the March/April issue in 1994. I think any IPA fan not familiar with these articles should check them out. Very informative. In my neck of the woods, my favorite version of IPA is brewed by Spinnakers Brewpub. With an OG from English Malt in the 1.060's, and around 60 IBU's of bitterness, this blonde-ish beer has a marriage of hop character and maltiness which is exquisite to the taste. And also locally Swans Brewpub produces (only periodically, unfortunately) an IPA which is in the darker range of the style, strong, and benefiting from generous dry-hopping. Ahh, choice in premium IPA! Another HBD post mentioned Bhagwan's Best IPA from Big Time Brewpub in Seattle. This beer is worth the trip to the brewpub alone (Try the Coal Creek Porter too). Pike Place Brewing (now Pike Brewing in a new, nearby location? Seattle brewers let us know) had an East India Pale Ale which I found tasty (goldings/fuggles hops ?), though lacking some IBU's. I would like to try that one again, given the good reputation of Pike Place beers. In addition I would like to mention that here in Victoria we have The Great Canadian Beer Festival, on November 1 & 2. The now burdgeoning B.C. beer scene is happening, some prominent U.S. Northwest breweries are attending again, and now a Special Edition bar will feature beers from Central/Eastern Canada; a good time will be had by all. Fifth year.....sixth year of the festival ? Brain cramp is starting to set in. See us at http://www.pacificcoast.net/~patkinson/GCBF.htm Private e-mail inquiries welcomed.
