Its now called Bergoff Brewery and Restaurant. They have a mighty good porter ! None of the waitresses or bartenders seemed to know much at all about the beers. According to them they were serving me an "ale-lager type beer" at one time. I'm still not sure excactly what that one was. I guess I did not know such a thing existed. Anyway, they also have a sampler deal where you can get one of each in small (~4 oz) glasses for about $3-4. It was quite the place if you like the beer, and a Hooter's opened up just down the street also...it just doesn't get any better than this :-) Return to table of contents

If you have a very small coolant flow area per wort flow area, keep in mind that the increased efficiency will cause the coolant to very quickly rise to the temperature of the wort, not vice versa. Therefore, in order to get the wort temperature down, you'll really have to be cranking the coolant throughput. With my water pressure, it is very unlikely I'd be able to achieve the desired degree of cooling unless the wort flow rate was throttled down quite a bit too. Put another way, if you're planning on a specific coolant area per unit area of wort flow, there is an optimal length of tubing to use, beyond which no additional temperature drop will be gained. Make sure that with your chosen flow "areas" that the length of tubing along with water flow rates approximately makes sense to get the degree of cooling you want. Also, keep in mind that regardless of what degree of turbulence you have in the coolant side, most homebrewers will not have turbulent flow in their wort, making this the limiting transfer rate. For example, if I use 1" vs 3/8" tubing for the wort, and the flow is laminar, it will take a lot "longer" for the heat to leave the center streamlines in the larger diameter case, requiring a longer tube.

He stated that it was traditional to make home-made beer for festive occasions. Methinks that in the early thirties, tomorrow would have been considered occasion enough. 8^) I think I can help with some of your questions, Bruce. I too was given some old beer recipes, with a bit more explanations given. >Comments: That last sentence sums up the attitude of the author -- "relax, >don't worry". Any ideas why it is recommended to "sweeten the crock" with >a baking soda solution? The tester (hydrometer) "B" and "W" graduations, >what do they mean? Why not put the crock on the floor? >What is a Filter Float? Bottle Caps with cork seals -- definitely ancient. I think the point of the baking soda to 'sweeten the crock' is simply to remove any off smells that may have developed in an unused crock. Being somewhat porous, if the crock wasn't previously cleaned well, or simply sat unused, it may have gotten a kind of punky smell. The universal cure for this seems to be old Arm and Hammer, you know, a box in the refrigerator and all that. The "B" graduation on the tester means bottle, as in "time to". Back in the daring and adventurous 'old days', Grandpa didn't ferment beer out completely and then add a measured amount of priming sugar. He let the beer ferment until there was just the right amount of fermentation left, that is, the tester said 'bottle' and he bottled and he *liked* it. None of this fancy schmancy Balling or Plato or S.G. or fiddledeedee. The "W"? You got me. "Wasted". "Whoops". "Where've You Been?" The crock not on the floor? Need some elevation, to facilitate siphoning later. My old homebrew directions describe something that has got to be your Filter Float. Take a board and cut out a circle slightly narrower than the opening of the crock. Drill a hole in the middle large enough to fit a siphon hose into. Pound four nails into the board near the outside edge, equally spaced around the circumference, such that the points of the nails extend about an inch and a half beyond the bottom. Place the siphon hose into the hole in the center, with the hose extending slightly beyond the bottom of the board, and float this device on top of the beer. It will allow siphoning of the beer near the top, away from the sludge at the bottom, and the nails will prevent the board from 'bottoming out' and picking up the sludge. Voila!

Did Fleischmann make a brewers yeast or was it their off-the-shelf bakers yeast. The baking soda is used to neutralize the acidity of the Purex, which I think was and still is a chlorine bleach. Rinsing with the baking soda should sweeten any residual sourness left by sterilizing with bleach. Peter Return to table of contents

Who was this guy?!? Having just returned recently from that lovely little brewing town, Plzen in Czechoslovakia I can tell you a little more about Gambrinus. There is a brewery named Gambrinus in Plzen. Seems he was a king. He was one of the kings of Bohemia, the western (non-slovak) half of Czechoslovakia. This region has always been pretty closely tied to Bavaria in it's brewing traditions. I don't know a lot of specifics about the king, but him and King Wencislaus (sp??) also of Bohemia, were big favrotes among the brewers in the area. I believe one of them was responsible for the laws that made it a crime punishable by death to export rhizomes (hop rootings) of the fabled Saaz (named for the Tzatek region of Bohemia, just north of Plzen) hops. good King JaH :-) Return to table of contents

Back in '82 I found myself in London, and repaired forthwith to the nearest pub for a pint. There was a fellow holding forth in there, and from his rant I took him to be a Scottish separatist, but the patrons largely ignored him until he leapt up on a table and announced to the company at large, "the Queen _DIDDLES_!" It was as if the place had suddenly been dropped in a blender: furniture and glassware flew, the barkeep leapt over the bar to join the battle, the barmaid slipped through a door I hadn't previously noticed behind the bar.

Date: Tue, 24 Dec 91 12:04:05 EST From: Jay Hersh <hersh at expo.lcs.mit.edu> Subject: Al vs SS testing One of the more ingenious testing means I saw exploited the density difference in these two metals. I think you'll need a CRC handbook to find the densities, but if you want to make sure the pot you have is indeed SS you can submerge it in water, check the displacement (probably best to use metric). Then weigh it, and divide the weight by the volume to get the density. If I recall the old discussion, the densities of Al and SS are signifiantly different that it should be pretty apparent if you've got the wrong one. Keep you're receipts :-)....

Date: Tue, 24 Dec 91 13:02:24 EST From: Jay Hersh <hersh at expo.lcs.mit.edu> Subject: Irish Moss & Head Retention Hmmm I have been using Irish Moss for years with no resulting loss in head retention. I also use a yeast nutrient. The yeast nutrient is made from dead yeast which is dried and ground up. This works under the theory that the best (most complete) source of trace nutrients the yeast need to maintain proper cell growth and maintenance is already in other yeast.. While some may claim this is an evil alien additive, I think since it is just from yeast to begin with it's OK. This may counteract any negative effects from Irish Moss, though I have been using Irish Moss longer than I've used the yeast nutrient, and don't recall any negative eefects way back then...

Date: Tue, 24 Dec 91 10:16 CST From: arf at ddsw1.mcs.com (Jack Schmidling) Subject: Jocky Box, Boiling Sparge Water To: Homebrew Digest Fm: Jack Schmidling From: Greg Roody - <roody at necsc.enet.dec.com> Subject: Jockey Boxes (re: Dan Graham) >I assume you want the fridge to chill the beer and not lager it. >If that's the case, you can buy or build a "jockey box". This is a large cooler with stainless steel or copper cooling coils/plates in it which you fill with ice. There is a much simpler device available. Come to think of it, it might be what's in the jocky box. It's a flat aluminum plate about 8x12x1 with a serpentine path inside and in/out hose fittings. You put it in a dishpan full of ice and hook the beer to it. It is incredibly efficient. When you tap a beer, the ice looks like it is running down a drain. It is even convenient for a couple of glasses. One tray of cubes will chill several. BTW, it also makes a great wort chiller but like everything else made of aluminum, I consigned mine to the recycle bin. But for those who don't mind losing a few brain cells, I highly recommend it. BTW... btw, in case it isn't obvious, wort chillers make great beer coolers but because of their capacity, only useful for parties. .........SPARGE WATER MOMILY..... The experts all agree that the temperature of sparge water should be around 170 degs F for maximal extraction. I think, however, that we have a problem extrapolating a commercial process to home brewing and if a homebrewer uses water at 170F, he will not achieve the same results. First of all, most commercial brewers sparge with a shower-like sprayer that impinges directly on the malt. In the typical homebrew setup, we are dribbling the water on a layer of water (1" typically) above the mash. This is done to avoid disturbing the filter bed with a stream of water. I take this one step further and place a small bowl in the mash to receive the water and distribute it evenly. We are, in effect, dribbling water into a three gallon bucket of water and the temperature profile thus created is far from what is desired for efficient sparging if we start with water at 170F. On my last batch, I sparged with boiling water (as usual) but this time, I took careful temperature measurements and here are the results. Sparge water: 210 Center of bowl: 155 Surface, midway to edge: 140 Surface at edge: 139 Edge, 2" below surface: 135 Wort outflow: 135 The level is maintained to assure that the bowl top is below the water surface. The edge is the edge of the mash kettle. Nowhere does the water temp even approach the desired 170F. Clearly, using boiling water to sparge in this fashion is not only NOT going to cause any problems but it is NOT even hot enough, if 170F is what is desired. Solving this problem presents a real challenge to the homebrewer. In my case, I have 7 gallons of water boiling that is gravity fed to the mash tun and it is a terribly convenient way of sparging. The thought of coming up with enough pressure (at the "proper" temp) to drive a spray, gives me a headache. The good news is that the beer tastes great anyway and perhaps the only effect is using a little more malt per gallon to compensate for the less than ideal efficiency. js Return to table of contents

Date: Tue, 24 Dec 1991 16:27 EST From: Frank Tutzauer <COMFRANK at ubvmsb.cc.buffalo.edu> Subject: pitching starters I've been using Wyeast for the last 6 or 7 batches, and I've regularly made a starter. Now that I've used liquid yeast for a while, I've got some questions about pitching starters (not to be confused with starting pitchers-- that's another sport altogether!). My questions are these. Assuming you can perfectly time your starter to coincide with your brewing: (a) When should you pitch (i.e., when in terms of how far along the starter is)? and (b) What should you pitch? Let's consider "when" first. My references on this are mixed. Paul Farnsworth, in the yeast special image of zymurgy, says you should pitch after the starter has become "opaque" and before the yeast "begins to settle out" (p. 35). The Wyeast package says to pitch after about 12 hours, at high kraeusen. Finally, Miller (p. 94) says to let the starter ferment completely out, pitching the slurry on the bottom. I have tried all three methods, but so many other variables were also changing that I'm not sure which is best. From a practical standpoint, I end up more toward the Miller side, but for no reason other than I want to give the yeastie boys plenty of time and have tended to err on the side of too much time. So, what is YOUR experience? Second question: What should you pitch? It seems to me that there are two options: pitching the entire starter, and decanting and pitching only the slurry. Miller decants and pitches slurry, since he lets his starter ferment completely out. Farnsworth doesn't say what he does, but I assume he pitches the entire starter since there is no slurry. Wyeast makes no recommendation (at least not on their package). I don't buy arguments about the starter altering the flavor of your beer. Afterall, it's only 2-4 cups of plain- vanilla wort. I don't see how it could alter the flavor much more than adding 2-4 cups of water. On the other hand, it seems to me that there are millions of yeasties still in suspension, so I figure why not put them into the wort too. Again, I've done it both ways and don't know which is better. What do YOU think? Now, if Nolan Ryan and Roger Clemens used liquid yeast, you would get starting pitchers pitching starters! - --frank  Return to table of contents
