---------------------------------------------------------------------- Date: 18 Feb 91 11:19:56 MST (Mon) From: ico.isc.com!rcd at raven.eklektix.com (Dick Dunn) Subject: making beer green [I see folks are getting started in time this year...usually we seem to end up waiting 'til the first week in March.] The usual bar method of making beer green for St. Patrick's Day is to put a drop of green food coloring in the glass before drawing/pouring the beer. This level of coloring doesn't work out well for homebrew colored before bottling, 'cause something seems to latch on to the color and precipitate it out. I don't know just what grabs it, but I've seen a pale-green beer with bottle sediment of a most amazing hue. Also, given a homebrew with substantial malt, hence good color, the green food coloring (weakened a bit) with the gold of the beer gives a rather unpleasant (IMNHRNWO) color. Several years ago, I made a batch of beer for a going-away party on 3/17, with which I attempted to produce multiple colors in one batch. (The batch was labeled "SPA" on the caps, allowing everyone to think it was "St. Pat- rick's Ale", when in fact it stood for "strangely polychromatic ale.":-) I left some bottles plain and added red, green, or blue coloring to various others. The red worked out OK, although I didn't use enough color and it faded a bit, giving a result approximately like a darker amber ale. The green gave the aforementioned bile (vile?!) green. The blue did best at producing the shade of green I wanted; I'd suggest this basic (blue+gold) => green approach. The color seems to continue fading with age. That shouldn't be too much of a problem since if you start today you'll only have a few weeks in bottle/keg. --- Dick Dunn rcd at raven.eklektix.com -or- raven!rcd Return to table of contents
Date: Tue, 19 Feb 1991 6:42:54 EST From: TSAMSEL at ISDRES.ER.USGS.GOV Subject: Re: Drum Tap I may have fixed the EDME BREWKEG tap. After polishing of the keg of SCUD bock (named for its exceedingly high carbonation due, I think to WYEAST 1007 {strange and sulphurous, beasties,they}), I dissasembled the tap whlie still attached to said keg,, sterilized it and put a smidgen of vaseline in the threads. I made sure that it did not touch the beer passage. I kept the keg full of H2O for a day in the fridge andto test, I tried the tap (It works like a champ....for the time being) Now it's full of bitter/brown and I'll say more in about a week. PS: At Richmond Brewers we were discussing WYEAST 1007 and came up with the question "What would typify a German ale?" We couldn't come up with any regional or style type that would fit WYEASTs 1007 name? Bashon regardless, Ted Return to table of contents
Date: Tue, 19 Feb 91 08:36:17 -0500 From: zentner at ecn.purdue.edu (Michael Zentner) Subject: Aeration bryan at tekgen.bv.tek.com writes about stuck fermentations and aeration. While I can't comment for sure on the first issue, it seems like a lot of people go through a lot of unnecessary trouble to aerate their wort. Prior to pitching, I remove the red spring loaded thing from my bottle filler, sanitize the white plastic tube, and put it in the neck of the carboy and just whip the heck out of the wort for a few minutes. When I'm done, there is usually a good 2-3 inch head of foam on top. It seems when you whip the tube around, the fluid passing by the submerged end of the tube causes air to be bubbled in to the point where you can hear it. Anyhow, it must work pretty well, because until recently, I have been letting my wort sit overnight to cool (just built a chiller) and I'm guessing that warm wort can drive off dissolved oxygen pretty well. I typically pitch a 12-18 oz starter made with a wyeast packet in the morning, immediately after this aeration process. Fermentation will usually take off full blast within 8-10 hours, sometimes even sooner. This method seems to work better than just attemptimg to slosh stuff around in the filled carboy and is easier than rigging up some bubbler pump. This will probably not work well with a 5 gallon filled primary. I use a 6.5 gallon carboy, so there's a good amount of head space to get up a good velocity on the tube.

Do yeast like green food coloring? What is *in* > green food coloring, anyway? Well, my friends and I did exactly this about a week ago for our latest batch of pale ale. It takes a fair amount of food coloring to tint five gallons of beer. (I didn't measure it, but probably about 1/4 to 1/2 of one of those tiny squirt bottles you get at the grocery store.) The color we achieved was, well, interesting. It's more of a sludgy green than the typical St.-Patrick's-Day-green-beer green. The beer was named "Pond Scum" after we saw the color. On the positive side, it's still green, the yeasties are fine, the beer carbonated well, and it tastes great. I think it will go over fine on St. Patrick's day. If you want to shock your brother, beer like this should do it. :-) Chris Burghart burghart at ncar.ucar.edu National Center for Atmospheric Research Boulder, CO Return to table of contents

Date: Tue, 19 Feb 91 10:28:31 -0700 From: dinsdale at chtm.unm.edu (Don McDaniel) Subject: Large Canning Pots In HBD #582 Craig Flowers asks "where are the large enamel canning pots" As I'm the one who stirred all this talk up, I guess it's up to me to summarize. Craig asked about 36+ quart pots. I've not found anything that large except for 40 qt. stock pots in stainless or aluminum. The best source for these appears to be Rapids in Cedar Rapids MI. Sorry, but I don't have the address here at work. Feel free to mail me if you're interrested. As for enamel, I looked all over town here without success. A thorough catalog search revealed the following: - ----------------------------------------------------------------------- 8 gal. enamel over steel (~16.5" diameter) $35 The Home Brewery P.O. Box 730 I've ordered one of these and expect it this Ozark, MO 65721 week. 800/321-BREW - ----------------------------------------------------------------------- 8 gal. enamel over steel $32 w/chrome spigot $45 The Cellar 14411 Greenwool Ave N. P.O. Box 33525 Seattle, WA 98133 206/365-7660 800/342-1871 - ------------------------------------------------------------------------ After a long and arduous search, I have determined that there is no such thing as a 32+ qt. stainless pot which will straddle two burners. The best bet is to get an enamel pot and be more diligent about stirring. Don McDaniel dinsdale at chtm.unm.edu Return to table of contents

Greene) -> Subject: Spring is here! -> The hops seemed to like it as they are growing like crazy. -> -> Anyone else seeing any activity?? Yep - I'm in San Jose, CA, in the east hills, an area which is very warm and dry. My Cascade is sprouting like crazy right now. This will be the third year. The Willamette has not sprouted yet; in general, it has been much less productive and vigorous than the Cascade. I propogated the Cascade last year by digging straight down with a sharp shovel to separate two bunches of sprouts at the root level. One I left, and one I moved to another hole. Worked great - I'm planning on repeating this year with both the Cascade and Willamette. Bob C. Return to table of contents

I hate to suggest this, but you're going to need to go back to the book and study those temperatures a little further. 121F is a good temperature to effect what's known as a *protein rest*, but will never allow any starch conversion. I mash my body-ful beers at about 158F; for dryer beers somewhere in the low 150s seems appropriate. Return to table of contents

I cannot find one. I can't tell if you're from Chicago. If you are, I saw a variety of enamel pots like you're probably seeking at a Mexican grocery (whose name I can't remember)--it was on Diversey, just past Richmond Street. A 32-quarter was selling for $22, which I thought was an excellent price. You might also try a restaurant supply house. Many of them carry a lot of used equipment--I got a great 8 gallon, heavy-duty stainless stockpot, with a drain valve on the bottom, for $10. Return to table of contents
Date: 19 Feb 91 13:57:00 EDT From: "DRCV06::GRAHAM" <graham%drcv06.decnet at drcvax.af.mil> Subject: Cidering In HBD 582 Mark Castleman, (spelling?) mentioned making cider in the gallon jugs from the store. I would like to make some such cider and would really appreciate the details, and, if possible, answers to the following questions. How much yeast per gallon do you use? Do you add any priming sugar after fermentation completes? Do you ferment at room temp? Is the gallon jug strong enough to withstand the pressure from carbonation after fermentation? I wonder what happens if you add some spices to the fresh cider before fermenting? Anyway, thanks for any other info you or anyone else can give. Dan Graham Return to table of contents
Date: Tue, 19 Feb 1991 14:42:01 EST From: "44636::DEE" at e814b.phy.bnl.gov (James Dee) Subject: Keg pressure problems Some friends and I recently bought a Rotokeg from a homebrew supply place. The Rotokeg is a spherical plastic container with a tap on the front and a screw-on top with an inlet for CO2; I'm sure it's similar to any other homebrew keg. I wonder if anyone has had any experience with these things. They seem fairly straightforward, but ours gave us some trouble. We were unable to get it to hold pressure for any length of time. Consequently, we had to draw out the beer a gallon at a time into a milk jug. Is there a standard procedure for using this kind of keg? I suspect that we've been doing something wrong, though I don't know what. I'd appreciate any advice. Thanks, --Jimmy Dee Return to table of contents

Date: 19 Feb 91 15:26:00 EDT From: "DRCV06::GRAHAM" <graham%drcv06.decnet at drcvax.af.mil> Subject: To Keg or not to Keg I'm a new homebrewer with bad eyesight. Bottling is one of the most difficult tasks for me, I either get them far too full, (all over my shoes) or two-thirds full, neither is acceptable. I have read a lot about kegging in this digest, but most of the discussion is by those already into this. I see in the Foxx catalog that I can get a kegging setup, complete, I think, for around $200. Now, my questions, if I may. What are the downsides of kegging, not counting the cost of the equipment. Does the keg need to be refrigerated, (I assume so, but I thought I'd ask)? Can I transfer directly from the secondary, or primary if that's all I use, to the keg? How long does the beer remain good in the keg? Is there more of a problem with freshness as the get becomes empty? If I make a half batch of a new brew, can I keg that, or does tne keg need to be filled. I guess those are enough for now. Sorry I can't just pick up a book and read all about it, but I haven't found any homebrewing books on tape yet. Thanks to any and all for your patience and, hopefully, answers.

When I said 121, I was thinking of a protien rest temp. Furthermore, it is the beta-amylase which works at low temp and the alpha-amylase that works at higher temps. So...please disregard my previous comments on the cause of the high final gravity. Next time I'll value accuracy over speed when formulating a response.

Date: Wed, 20 Feb 91 00:03:08 EST From: Chris Shenton <chris at asylum.gsfc.nasa.gov> Subject: Yeast -- culturing supplies? I'm psyched to start saving slants of yeast, and am looking for sources for agar, petri dishes, tubes, loops, etc. Who sells in reasonable quantities for fair price? And what is this Yeast Bank / Freeze Shield stuff? it sounds like you're supposed to add it to your sample/culture wort then freeze it, but I dunno. Finally, the continuing saga of my failure to culture yeast from bottles continues. Not only has Sierra Nevada failed me, but now also Chimay. I don't think it's lack of sanitation, as neither starter developed an infection -- the bottles just sat on the fridge and stared at me. Previously, I speculated that by the time these beers get Back East, the yeast is dead. Can anyone on east coast whose done this tell me what you used? Thanks in advance. Return to table of contents
Date: Wed, 20 Feb 91 00:20:34 EST From: Chris Shenton <chris at asylum.gsfc.nasa.gov> Subject: kegging -- excessive foam and low carbonation A while ago, I posted a tale of woe, trying to get my first keg batch to carbonate. My second through fourth (most recent) had similar problems: excessive head, but rather low carbonation. I primed with 1.5L saved wort (at about 1.060, 1.050 and 1.080SG, respectively), according to calculations a la Noonan. After Florian's recommendation, I reduced the CO2 pressure to sane levels, which meant I rarely had to apply CO2 from the cylinder. Now, the third batch, a stout, began to develop nice carbonation after maybe 3 weeks, and the froth seemed to dissapate. I don't know if this is due to sufficient aging, or reduced pressure in the keg due to consumption of beer. The second and fourth batches didn't survive long enough in the fridge to tell, really (tasted too good :-), although the fourth sat in the keg at cellar temperature for 3 weeks before cooling. Some of this may be due to the high gravities, I'm not sure. Anyone else encounter similar behavior? When I bottled, I always got textbook carbonation -- maybe even a little too much, and the froth was normal for style(s)... I've just put a fermenter full of lager (based on Norm Hardy's Andech's/Munich -- thanks!) in the fridge, and I could use some hints on fermenting and lagering it. (eg: if `lagering' the period *after* priming? or does it apply to the whole cold-ferment, cold-prime, cold-store thing?) Thanks again! Return to table of contents
