---------------------------------------------------------------------- Date: Mon, 30 Apr 90 08:55:23 EDT From: (Mark Stevens) <stevens at stsci.edu> Subject: coffee beers In Homebrew Digest #408, Chuck Coronella asked about coffee used in beer. A couple months back (I believe in January) we had discussed using coffee to flavor stouts. Seems that several people have tried doing this, with generally good results. I brewed a batch on January 1 that was based on Papazians "Dark Sleep Stout"; to the basic recipe I added about 1/2 cup of dark molasses and 10 cups of brewed French roast coffee. The molasses was probably NOT a good idea to add to this brew, but the coffee gave the stout a very pleasant aftertaste that seemed to be fairly subtle and to come through mostly as an aftertaste. Yesterday I opened a bottle that was warmer than previous samples (about 60 degrees), and in this bottle the coffee flavor was MUCH more prominent, virtually overpowering the stout flavor. My recommendation is to use either less coffee, or perhaps to be sure to drink it fairly young, and to drink it chilled. If you want, I'll repost the recipe I used.

The question is, can I brew > beer? You can *always* brew beer. :-) Unfortunately, high fermentation temperatures can produce off flavors. My early brewing days were in Texas where I brewed and stored in the garage. It routinely exceeded 100F, but the brew was still drinkable. Now that I am in the Great White North, the temperatures are a little more under control, and perhaps my tastes are refined a bit, so I suggest you attempt to cool it, if you can. I have heard of folks placing the carboy in a large tub of water, with towels acting as wicks to draw the water up around the carboy. The evaporation can cool your brew by several (10?) degrees. A fridge would probably be better if you are planning on any real lagering. - ----------------------------------------------------------------------- Bob Techentin Internet: techentin at Mayo.edu Mayo Foundation, Rochester MN, 55905 USA (507) 284-2702 - ----------------------------------------------------------------------- Return to table of contents
Date: Mon, 30 Apr 90 09:50:24 EDT From: Chris Shenton <chris at asylum.gsfc.nasa.gov> I made a batch I called Cafe Stoudt. Used a half *cup* of french roast beans, coursely ground in my grain mill. The coffee taste is difinitely noticable but works very well with the roastiness of the stout. Next time, I would add more roasted barley, as the stout's roast taste underwhelms the coffee's. I had also hoped for the caffein (sp?) kick, but I doubt 1/2 C in 5 gal is enough to lose any sleep over... Return to table of contents
Date: Mon, 30 Apr 90 12:30:06 EDT From: boubez at bass.rutgers.edu Subject: Lactose I'm planning to add some lactose in the next batch, to get a little more sweetness in the beer. I'm not sure, however, of the orders of magnitude to use. Is it in spoonfuls, cupfuls or pounds :-)? For example, is one cup a reasonable amount?

Date: Mon, 30 Apr 90 11:24:46 PDT From: pms at Corp.Sun.COM (Patrick Stirling (Sun HQ Consulting Services)) Subject: Coffee Beer My last batch was 'Mocha Porter'. From memory, the recipe was - 6.6lb Amber Extract (M&F) - 1lb Crystal - 1/2lb Chocolate - 1/4lb Black Patent (not cracked) - 1/2lb Colombian Supremo whole coffee beans - 1/4lb cooking chocolate I can't remember what hops I used, sorry! It's come out well, very full bodied with a very distinct coffee taste and aftertaste. Next time I'll use less. The only problem is that there's no way (that I could think of) of sanitizing the coffee beans. I tossed them into the primary fermenter (a plastic bin), then racked into a 5gal glass carboy after 3 days (leaving the beans and a *lot* of sediment behind. Then I bottled after another 3 weeks with 1/2cup of light dry malt extract. Again, a *lot* of sediment (at least 2"). After a couple of weeks in the bottles I tried it, and it was already fizzier than it should have been! Now, another couple of weeks later, it's a little fizzier still, but not too bad. I plan to drink it pretty fast! patrick Return to table of contents

[yerga at cory.Berkeley.EDU (Chris Yerga)] > The yeast had covered the surface of the wort by midnight and was > bubbling away at the rate of 3 or 4 bbles per second by the next > morning. Fermentation continued in this manner until the second > morning (48 hours after pitching), when the head on the wort had > fallen. I haven't seen a single bubble since > I don't have an answer for this one, but I do have the exact same symptom. I started a batch of "steam" beer about five weeks ago. After three days in the primary I racked into the secondary, and it is still showing some very slight signs of life. About a week ago I got another batch going (a basic lager this time), pitched it, and three days later it was totally quiet, after a vigorous start. The two batches were made from the same amount of the same extract (6 lb. of a bulk Canadian light), and used the same yeast (Red Star lager). The steam beer had some crystal malt added to the boil, and that's the only difference. Both batches were kept at the same temp throughout fermentation. I racked the quiet stuff into a carboy anyway, on the theory that it couldn't hurt. My plan is to give it another day or two to wake up. If it doesn't, I'll add about 1/2 cup of sugar, boiled into syrup, just to see if there's anything happening. I figure that small amount won't affect the taste much. If it still doesn't show bubbles, I'll try repitching with fresh yeast, I guess. The wort tasted pretty good when I racked into the secondary, so I think it'll all be okay if I can get the stuff carbonated. My bet is, same for your batch. [JEEPSRUS <ROBERTN%FM1 at sc.intel.com>] > krauzen(sp?) fell. It's been in the secondary for a week and a half > now, as of 4/26. I've left stuff in the secondary for 8 - 12 weeks without bad results. Then again, I'll drink anything if I made it myself. Seriously, the beer tasted fine. Since the secondary is a completely closed oxygen-free environment (assuming you used a glass carboy and fermentation lock), any deterioration should be pretty slow. Return to table of contents
