What with the talk about "Old British Beers and How to Brew Them," I noticed there are also two books in the Homebrew Classics series by Clive La Pensee & Roger Protz ("Stout and Porter" and "India Pale Ale"). Has anybody out there read these? I'm curious as to how they compare to the Classic Beer Style Series. Return to table of contents

If you don't make it but happen to be in Munich itself they have a bierhall (I use the term loosely, it is more of a pub). It is called Andescher am Dom. It is located behind the Frauenkirche (the main big one). I highly recommend the dunklewiess. And the food was the best we found while in the city. S Return to table of contents

But many of the small restaraunts in the city center serve styles from all over Germany. There is one in particular (the name eludes me now) that actually advertises the fact that they are the only pub in the city that serves kolsch. Yes the trip to Andechs is well worth the rental car or train ride from Munich. They do offer tours of the brewery, but you have to schedule in advance. Have a good trip.

Question 2 first because it's a short answer - I don't know. See my reposting of Geoff Cooper's notes yesterday and today. We HBDers should try to do this. I'd love to try to brew a 100% blown malt porter made with the kind of malt that Geoff describes. If anyone has success kilning this, please post. Question 1 - John suggests toasting pale malt 60 minutes in an 350F/175C oven for an approximation of modern brown malt. See pp. 265-266 in the hard copy - don't know if the online pagination is the same (http://www.howtobrew.com). HBBAHTBT's instructions are a bit more detailed. Buy the book! Oh, all right. I'll limber up my fingers and type up the instructions for chocolate malt. I trust it's a short enough excerpt to not violate copyright. But buy the book anyway. You'll like it if you are interested in historic British beers. "Roasting Method "Line a large baking tin with aluminium foil, and pour in pale malt to a depth of 12 mm (1/2 inch). Place in the oven (preferably fan-stirred) at 110C (230F) for 45 minutes to dry out the malt, then raise the temperature to 150C (300F). [instructions for pale amber and amber deleted] ... [after about 75 minutes] "raise the temperature to 175C (350F) and wait until the cut cross-section [average of 15-20 corns cut across the center with a sharp knife] is a full buff, i.e. about the colour of the paler types of brown wrapping paper. When the correct colour has been reached, remove the tray from the oven, allow to cool and store the roast grain in an air-tight screw-top jar. ... If used soon after production, the flavor imparted by home-roasted grain is superior to bought grain." Harrison cautions that the times and given are only a guide and you may need to adjust them. John Palmer suggests aging the grains for two weeks for "harsher aromatics to escape." I have used freshly toasted/roasted grains with no problems. I think that aging the beer a bit longer rather than the grains is the way to go. Hope this helps.

Date: Fri, 31 Oct 2003 07:56:51 -0800 (PST) From: Tim Spencer <spencer_tim at yahoo.com> Subject: Why I stopped Brewing: During the period of about 7-10 years ago, I took up brewing; brewed several batches from extract; and then did some partial mash (which consisted only of steeping grains in water before the boil). I was never all that satisfied with the results. I did not produce anything near as good as I had hoped. Then, during that time period (1993-1996), great microbrews became available at about $5-$6 per six-pack (which is just about what it cost me to do an extract homebrew.) So at that point, why bother. So I stopped and became a microbrew enthusiast (still am). I know going all-grain would have produced much better results. I am now thinking about doing a couple more batches to see if my interest perks up. But the cost to produce 2 cases from an extract kit is approx. $30-$50. At that price, you can buy 2 cases of many fine microbrews and enjoy all the taste with no labor. My main question: Can anyone relate an experience brewing an extract that produced great results? I do not mean superior, like I would expect from an all-grain brew; but decent enough that it compares favorably to a store-bought microbrew? If so, what did you use? Also, the great debate over yeast in HBD during the 93-96 period was that liquid yeast (Wyeast) produced a better product. Any change in that opinion? Thank you-I am reading HBD again!

I'll be trying to add to John Palmer's (?) experiment, >prepared for the AHA Conference this summer, to see how much the water >influences the hop expression. As Martin Brungard pointed out >it was Al Korzonas who unsuccessfully tried the experiment at the >AHA convention last summer. The beers had not cleared yet. And here we have a problem. Al's design was designed differently from what I would have done. I think he added the salts (gypsum, as I recall) to the half of the finished beer, not to the mash. This ensured that there were no differences between the two batches beyond their ion content. He was looking for differences in flavor, especially hop character, from the sulfate. But this is not the way beers are brewed. The minerals are present from the start of the mash, and this makes a big difference. For one thing, I think that the hop bitterness character that comes from sulfate may come from reactions during the boil, not simply the presence of sulfate in the final beer (although Al's experiment is a good test of just the latter). Furthermore, Ca++ in the mash and boil are important for proper hot break formation and beer clarity. The fact that Al's beers hadn't cleared is indicative of this. I seem to recall his efficiency was lower than expected as well. >The question is, should the other brew use distilled water or my normal, >soft well water? I think it depends on whether or not you want a good beer or a good experiment. Since I'm not going to lose anything if the beer is crummy, I suggest distilled water for contrast. ;-) Three brews would be best, but that's more work. And, of course, it is inevitable that there will be differences in the brews simply because you don't have tight control on all the variables. (At least I don't). Marc Sedam's comments seem confusing and contradictory. I mean this in the friendliest way. I'm sure he knew what he meant, but I don't: >The best experiment would be to use distilled water. Your problem is >going to be the calcium levels in the water to ensure proper conversion. > If you can get your hands on calcium chloride to the tune of 50ppm in >the water, that's the way to go. You could use slaked lime to get >calcium in the water too, but it may drop the pH too much. Did you mean to write "raise the pH too much," not drop it? I don't think the pH lowering ability of the Ca++ in the mash reactions (phytic acid and all that) is as strong as the pH raising ability of the OH(-), especially since there are two OH(-) ions for every Ca++ ion you add. (see below) >I'd prefer the lime addition (since the other ion is -OH, which is >already in the water, versus Cl(-) which is not) but wouldn't do it >without a pH meter handy to ensure the pH of the mash is in the 5.2-5.5 >range. My gut tells me you could add enough lime to hit the 50ppm Ca >threshold and still convert the mash, but you may not want to take the >chance. You say that CaCl2 is "the way to go," but then you say that you prefer lime. I'm confused. Like you, I'd be concerned about adding OH(-) since there is likely little dark malt in the grain bill for an English pale ale (although crystal is somewhat acidic and will neutralize some alkalinity). You may be right that you could get enough Ca++ with Ca(OH)2 without so much OH(-) alkalinity that the mash pH would be too high, but I'm doubtful. Regardless, I think you may not have understood the design. Jeff was proposing to use distilled water plus salts to mimic Burton water for one brew. His question was for the other, "control" (my term, not his) beer. He asked whether to use distilled water or his normal, soft well water. Were you thinking that he was wondering whether to use distilled water or his water for the starting point for the Burton water? I'm sorry to be jumping all over you, Marc. It looks like you just hadn't had your second cup of coffee when you wrote this. Or maybe we're just not on the same wavelength. ;-) The experiment sounds fun. I look forward to the results.

In 1999, the AHA made a controversial decision to use a milk stout as the recipe for the big brew day in May. The recipe called for adding it to the boil. That's what I did, and it turned out fine.

Date: Fri, 31 Oct 2003 12:12:23 -0500 From: "Dave Burley" <Dave_Burley at charter.net> Subject: Stability test, grain beetles, foamy bottling, grain mash,diatomaceous earth Brewsters: Steve Alexander remembers that G. Fix once suggested you take a wort sample midstream and seal it in a sterilized vessel and keep it at an elevated temperature ( 80F or so ) and observe the wort for spoilage. First, George didn't invent this method if that is what you are suggesting ( it is a standard test method, as I recall) and I doubt George would have suggested you seal it up without a vent of some sort, in case you get some yeast in it or other CO2 producer. I couldn't find it in his Amalysis of Brewing Techniques nor could I find a book I used to have which is the ABA test procedures. - ----------- Isaac, I'd take the grain beetle infested grain back if you can. If not, put it an a heavy duty garbage bag and thoroughly flush it with carbon dioxide and let it stand for a week or so. I'd repeat this. Keep it in a plastic box like a Rubbermaid storage box to prevent your other grains getting contaminated and millers all over your house. - ----------------- Dave King suffered from foamy bottles when he recently tried to bottle some beer. Dave, foamy bottles are what you want when you bottle, as the foam ( fob) helps push the air out of the bottle neck. Cap right on top of the foam. If you are having trouble getting enough beer in the bottle then chill the beer in a fridge first and if necessary chill the bottles also. Look at it this way wth no food in the refrigerator you may lose weight from not eating and your fridge will end up being the cleanest it has been in years! Now, about the SWMBO, well, no advice there. Make sure the beer is finished fermenting by using Clinitest kit to be sure the fermentable ( reducing) sugars are less than 1/4%. This especially true if you changed yeast as you said and if its still bubbling while you are trying to bottle it.. - ------------------- Chuck Binkley asks about the difference between an all malt mash vs one with gelatinized barley/malt mash. Sugars should be about the same BUT you will get other stuff from including the barley grain and that is a better head retention and the possibility of a little haze if you don't mash in the lower T regions to take care of the gums and some proteins. I would start at about 30% grain so you can see the difference easily. Today's malt should go as high as 1:1 easily, but it may take a little longer to mash, dependng on your mash T profile. Low T mash region is important. - -------------------------- Michael Hartsick is thinking about using a champaign ( sic) yeast to get to a lower SG in his barley wines. This will only work if for some reason the yeast you chose will not finish off the sugars. The final gravity is pretty much determined by the mash profile in most cases unless the yeast cannot ferment to the high alcohol level chosen. - ------------------------- I sincerely doubt if diatomaceous earth will kill any grain beetles, but would like to see some documented proof.

Lime (CaOH) raises pH, not lowers it. That would be...shall we say...a major error. The underlying concept that it may swing the pH out of the "normal" range for mash conversion is the same. OK...I'm grasping at straws. The other part about CaCl is more about what you're trying to accomplish. Adding chloride to the liquid will have some effects on palate fullness and other subtle tastes, in addition to adding the required calcium. That may throw off the experiment. Adding slaked lime has the advantage that no other ions are being added other than hydroxyl groups (-OH), which won't effect flavor, but the pH will be RAISED possibly out of range. I was guessing that you might could (a good Southern saying) add lime in a quantity large enough to add required calcium but low enough that the pH increase would be easily compensated by the mash reactions. So I was punting to Jeff G. on what he wanted to do. I got the design though. I was trying to suggest that he should use distilled water plus JUST enough of another salt to add 50ppm of calcium to the mash and little if anything else. Hope that was clearer.

What, is JP trying to pawn some of his stash off on you ;-) I can't say I can tell you what the most likely consequences are, Harold. But I can tell you I've used 5 year old malt and made wonderful beer with it. When I buy malt I immediately double-bag it in ziplok freezer bags. This summer I made several batches from 4 and 5 year old malt that was stored this way. The ziplock bags were in large plastic bins, and the bins stored in my shed. So 35C in the summer and -35C in the winter. Heat does not seem to bother grain so much as long as you keep the moisture down as well.
