---------------------------------------------------------------------- Date: Fri, 5 Apr 91 09:03 EST From: BMENK at ccr2.bbn.com There are only two actual brew-pubs I know of in Minneapolis: one is called "Taps" and is located in the Riverplace center across the river from downtown Minneapolis. The other is called "Sherlock's" and is located in one of the western suburbs - Minnetonka as I recall. Sherlock's certainly has the better reputation, (and better food as well). I've only tried one of the beers at Taps, and found it merely adequate. I don't remember what it was called, but it was an average pale ale. They were in some financial difficulty last summer/fall and may have succumbed - I haven't heard. There are some other brew-related things worth seeing there though. The Summit brewery on University Avenue in St. Paul offers tours and samples if you call ahead. They make a delicious pale ale and a porter, plus some seasonal brews as well. In New Ulm (about 80 miles southwest of the Twin Cities), Schell's brewery is worth a visit. They make some excellent brews - both under their own name and number of "brewed under license for...." products. The other small brewer in the sate is called Cold Spring and is located in the town of Cold Spring, 15 miles south of St. Cloud. Last I heard they weren't giving tours or samples, but call to be sure. Some of their brews are allright, others have the virtue of being incredibly inexpensive.

I have heard this before, but have also heard that you are just as likely to find dried corn sugar in the dry malt extract as you are to find liquid corn sugar in the liquid malt extract. Anyone else with any evidence? The safest bet is to buy from suppliers who tell you what is in the extract, such as with Yellow Dog. Personally, I wouldn't brew without some dry malt extract in the house, because I can use it in any quantity I want, whether for priming or during the brew. However, I really like the 6 lb. boil-in bags of extract. Every so often I order a bunch, typically from Williams Brewing (they tell you what malt went into the extract). I haven't bought a can of extract in years (except for Yellow Dog). Internet: jdecarlo at mitre.org (or John.DeCarlo at f131.n109.z1.fidonet.org) Fidonet: 1:109/131 Return to table of contents

I guess there has been plenty of discussion of this already. Let me just add that when I toured the Old Dominion Brewery, I asked about their yeast. He said that they were surprised to find that they hadn't had to stop re-using their yeast yet (at that time they had been brewing weekly for about 6 months). Every week or two they took samples and had them analyzed in a lab. Internet: jdecarlo at mitre.org (or John.DeCarlo at f131.n109.z1.fidonet.org) Fidonet: 1:109/131 Return to table of contents

My only question would be related to the amount of "head space", or air between the top of the beer and the cap. I leave about 1/4 to 1/8 of an inch between the top of the beer and the cap. I used to be more haphazard, with about an inch of variation. This seemed to cause uneven carbonation within a batch (more head space, less carbonation).

I don't know, but I have had pretty good success adding some malted wheat to my recipes to increase the head retention. So I usually add a little crystal malt and wheat malt now to my extract beers.

I'd like to add that most people also recommend that you crack the grains first. If you don't have a grain mill you can do this with a rolling pin. Try not to grind the husks into powder, as that will result in astringency. (You'll probably get some powder from the sugary innards of the grains, but that's of no consequence.) Crystal malt will add color, sweetness, body, and a caramel note. Cara-pils will add sweetness and body only. I suggest that you consider steeping the grains at 168 degrees for 15-20 minutes rather than removing them immediately when the water reaches that point. I have removed them by pouring the whole mess through a wire mesh colander resting on a big bucket. The grains end up in the garden, and tea gets poured back into the boiler. I've not seen any recipes calling for as much as two pounds of crystal malt. That certainly doesn't mean that they don't exist and are not wonderfully tasty, but the ones I've seen all call for a pound or less. Also, cracking two pounds of crystal malt with a rolling pin will take you a long time -- I have found it to be a rather tedious job. -- Marc Return to table of contents
Date: Fri, 5 Apr 91 10:06:59 CST From: rickel at cs.utexas.edu (Jeff Rickel) Subject: Slow fermentation In my first batch, I used Red Star Ale yeast. There was a steady increase in seconds per glub, and fermentation was complete in 6 days. My last two batches I used Whitbread Ale yeast. In both cases, fermentation was vigorous within 24 hours (about 1 glub per second), and it steadily slowed to about 1 glub every minute and a half. In both batches, however, it stayed at this rate for about two weeks before reaching a specific gravity low enough for me to bottle. Why is it getting "stuck" at this slow rate? Low yeast population? Or is this typical? All my brews have been partial mashes, all malt, room temperature for fermentation about 65-70 degrees. I think I am aerating the wort sufficiently before pitching the yeast, and I rehydrate the yeast before pitching. My fermentation lock is the S type if this helps in interpreting my glubs per second figures. Jeff Return to table of contents
Date: Fri, 05 Apr 91 11:50:43 EST From: hersh at expo.lcs.mit.edu Subject: Lanny H's bottled water technique, CO2 techniuqe, Yeast repitching Lanny (and others follwoing this thread) be sure that those are *GLASS* carbouys. If not I would not adopt this technique. Only certain types of plastic are rated for containing alcohol. Other types leach carcinogens in contact with alcohol. I am farily certain that the plastic bottles used by many bottled water companies these days *ARE NOT* safe for storing alcohol. You should either use only glass, or contact the FDA or BATF to determine which types of plastic are safe for alcohol storage and then investigate as to whether the carbouys (if they're plastic) are safe. I'd sure hate to see someone inadvertently poison themselves with homebrew. > I recently kegged up a batch of wheat beer in my new draft system. > I followed a chart of CO2 PSI vs. Temp for different volumes of > CO2 for different styles of beer.

Gee that's so scientific. I usually just chill the beer down to 35-40F and hit it with 25-30 lbs CO2 till you hear it stop flowing. Unhook the CO2 shake it up like 40-50 times, toss it back in the fridge. I do this 2 or 3 days in a row, then let it sit in cold store for another 3-10 days (depends on my mood and how low I am on homebrew). Never had a problem this way, no messy charts to consult :-) :-) CR says> I've never investigated the minimum time required to carbonate, >but I've applied gas on Thursday and had fizzy beer on Friday. I'd watch out though. I did this once and all my fittings weren't quite sealed (not me, on my kegs ....) This resulted in leaking away a whole tank of CO2. Remeber one thing, we're talking about dissolviong a gas into a liquid so rates of dissolution (sp?) apply here. The rate is temperature dependent. My technique puts a higher pressure of CO2 over the beer, one that exceeds the equilibrium pressure at the beer temp, thus the excess CO2 will dissolve into tthe beer over time. The lower the temp (up to freezing) the higher the rate at which the gas will get absorbed into the liquid. By hitting the tank up 2 or 3 days in a row I replace the gas that has dissolved (thus lowering the CO2 pressure over the beer) with more gas and re-establish an overpressure. There is some practical saturation level at which the beer will cease absorbing CO2. The last thing I do before tapping is to yank the pressure release valve to let this overpressure off. Then I hit the beer with a normal dispensing pressure (say 7-10lbs). I hope veryone understood that, or at least somebody understood that, I mean what the heck it works for me. Just a not on yeast repitching. Before microbiology came into vogue the standard technique was to pour the new batch of beer into the fermenters over the top of the yeast cake left by the old batch. While from a scientific standpoint this may not be optimal it obviously worked well for centuries (either that or the Brits and Germans were drinking cruddy beer until Louis Pasteur the Frenchamn came along hmmm......).

I can not remember the name, but you can't miss the place if you find the Lounge next store. Last time I was there (1988) they had about 60 taps. Many imports as well as many micros, including 2 or 3 Sprecher brews (Black Bavarian is my favorite). The atmosphere can get pretty rowdy depending on what night it is. Generally tho, it is a pleasant place to try a variety of brews on most evenings. If you are like most homebrewers, considering going pro at some point in the future, don't miss Sprecher's. Randy left Pabst (if memory serves) to do his own thing. He built his brewery from recycled equipment and is a very interesting guy to talk with. Beers are excellent also. Lakefront is another "seat of pants" operation. They were not open when I was in town last, but I have read many nice things about the guys behind the place as well as their products.

Is anything like > this done? Or would something _bad_ happen? I dunno, Carl. Why don't you give it a try, and report back ... Actually, something like this is frequently done in commercial brewing. The examples that come to mind are Pere Theodore's culture of 5 yeast strains in Chimay, and Whitbread's 3 strains, as described by George Fix in the "Yeast" special issue of Zymurgy ('89?). As I recall, two of those three strains acted pretty much as you describe, one being a rapid starter but getting "stuck" after the simple sugars were gone, and the other being a slow starter but quite attenuative. The role of the third strain seemed to be to flocculate cleanly, taking the other two with it. This approach wouldn't be easy to translate into strains available at the local homebrew store, though I have read of folks making truly heavy barleywines who pitch an ale yeast first, and then a Champagne yeast a week or so later. The problem with pitching them at the same time is yeast's otherwise desirable trait of "taking over" its environment. Whichever strain established itself first might very well "off" the other strain. = Martin A.

First, many thanks to all who send me copies of the digests 62 and 63. I got four or five copies, and all were sincerely appreciated. Second, I picked up a sixer of Catamount Porter yesterday.

I loved it, but that might be inexperience speaking. The flavor seems rather complex, going through several stages in the mouth. The lingering bitterness is very satisfying. The store had some Sam Adams Doublebok, but my wallet was empty. Is this good stuff? Third, I received my catalog from Carolina Biological on Friday. Wow! This is the mother of all catalogs.

(Maybe I'll send the bill to the person who mentioned it in the first place, [grin]). The only disadvantage is that culture tubes come in quantaties of a hundred odd. I could probably use a dozen or so, but I don't think I'm going to have a hundred different slants.

Date: Mon, 8 Apr 91 12:43:48 EDT From: cjh at vallance.HQ.Ileaf.COM (Chip Hitchcock) Subject: bottled water wrt lhoff at acc.stolaf.edu's suggestions 1. Bottled water can vary widely. It usually has less chlorine than tap water, but I'd ask the bottler to be sure. Also, if it really is spring water (instead of municipal water that's been filtered and dechlorinated--- an association of municipal waterworks says that's a common stunt) the mineral profile will be different from tap water, so you should get a complete analysis if you're thinking of adding minerals. 2. The prices quoted are rather high. I can get 5 gallons of bottled water at the local supermarket for $3 (in recyclable plastic containers); I would expect Mpls to be cheaper than Boston, so you're probably paying (in effect) at least $2 "rent" on the carboy each time in addition to the $6 tied up in the deposit. At this rate, $20-25 for a carboy you own is good if you think you're going to keep brewing for more than a few batches. Return to table of contents

What can I expect? Will the smell go away eventually? Is my beer gonna taste bad (due to the Hydrogen sulfide anywauz ;->)? What? Also, my last batch, a barley wine using Tom Caxton kits, is still pretty sweet after a couple of week aging? Should the stuff get less sweet? And if so can I look forward to 12oz glass grenades in my closet?

Date: Tue, 9 Apr 1991 10:42:09 EDT From: R_GELINAS at UNHH.UNH.EDU (Russ Gelinas) Subject: % fermentables Is there any info. available regarding the percent of fermentable sugar in diferent types of malt? I never use "recipes", so I don't know what the FG will be beforehand, but I was thinking there may be a way to calculate it. Let's say you have an OG of 1.100, just to make the math easier, and a type of yeast that will attenuate to 75%. Then you should get a final gravity of 1.025 . But the yeast will really only eat the fermentable sugar. So if, let's say, 80% of the gravity, or 1.080, is fermentable sugar, then the yeast will eat (.75 * .080 ) = .060 of the gravity, which leaves a final SG of 1.040. So, if you know the attenuativeness (?) of the yeast, the percent of fermentable sugar, and the original gravity, you should be able to calculate the final gravity. The actual % of fermentable sugar is the only missing variable. Any thoughts? Russ in Manch. Return to table of contents

Just in case you are and you get thirsty for good beer, visit the Buffalo Brewing Company in Lackawanna. It's owned by the guy who owns the Buffalo and Rochester Brewpubs, which have been making extract-based beers for a while. The new brewery makes all-grain beers using only German malt. Right now they have their flagship "Buffalo Lager", which is a version of Munich Helles, plus a Pilsner, a Weiss (in the Bavarian Weizen style), and a Bock. All four are really nice, well-made beers, and you can get them at stores in the area or at the brewery, which has a restaurant/bar attached. To get there, take I-90 to the Lackawanna exit and take Ridge Rd west ~1 mile. At the light for Abbott Rd, make a left (south) and go ~1 1/2 miles. The brewery is on the left, 1830 Abbott Rd, just before the road goes under the viaduct. Awesome beers; well worth the trip. Ask about good Buffalo chicken wings while you're there; why the hell not? I recommend the Anchor Bar, but have heard that Duff's is great, too. Enjoy, STEVE RUSSELL Return to table of contents

Having a microphone and digital signal processor handy, I promptly did so. It's very rewarding, and I recommend it to those with the means. - -------------------------------------------------------------------------- Mike McNally mcnally at wsl.dec.com Digital Equipment Corporation Western Software Lab Return to table of contents

Papazian says to just let it build its own carbonation, so I haven't put CO2 in it until pressure falls from drawing out beer. Is one in fact supposed to put in more pressure for a few days before drawing the beer? Return to table of contents

In trying to get the most efficient chill possible, I rigged up this for a wort chiller, but I have some minor questions to people using this. Sorry if this one has been hashed recently, but I picked up HBD with #574, haven't got around to the archives, and feel I should contribute SOMETHING, dammit! An immersion chiller should be more efficient with a constant flow of water for heat exchange, plus, I had heard about people doing this. What I did was straighten out about a 20' length of copper tubing, and shove it inside about 23' of garden hose, starting at the end I cut off of the garden hose. Then I cut a hole in the garden hose about four feet down from the connector end of the hose, pushed the end of the copper tube through, and made sure there was about 6" sticking out of the end of the hose and also through the hole I cut. Then I sealed the hole with RTV silicone, and coiled the whole mess back up again. Here is a simplistic diagram: <---3'----><--------------------20'--------------><-6"-> __ \\ <-- copper tubing |||\______\\_____________________________________ ||| \\ |------ <-- copper tubing ||| _____________________________________________|------ |||/ ^-- garden hose The concept is, to run the syphon right from a lauter-tun (or strainer in a bucket), through the copper tubing, while running cold water through the garden hose to achieve a REAL fast chill. Also, you can easily regulate the output temperature simply by running more or less tap water through the hose. I just got done inaugurating this device, and here are my observations: 1) This thing does NOT need 20' of copper tubing. Maybe an immersion cooler might need that length, but I was barely running the tap water, and getting wort out at ~60F. I would think 8-10' would suffice. I may split mine into two wort chillers. 2) My question: Everybody I know who uses a device like this uses a counterflow, that is, cold tap water running in an opposite direction to the wort flow. However, it just made intuitive sense to me to send both in the same direction: The hottest wort will exchange the heat with the coldest water and some sort of equilibrium will be reached by the time you reach the end of the chiller. Why would the chiller be more effective with counterflow? Which method makes it easier to regulate temperature? Enquiring minds just GOTTA know! thanks, -dr.d Return to table of contents
