---------------------------------------------------------------------- Date: Thu, 4 Mar 93 15:42 CST From: korz at iepubj.att.com Subject: Lager starting In a recent post, I described *one* method that is used to start a lager fermentation, in which the ferement is started at a warmer temperature and then cooled for the main ferment. Jim Busch, in private email pointed out: ><stuff that kills some bacteria" and then raise the temperature. It's sort ><of backwards from one common way to make lagers: to start the batch at ><around 65F and then once the yeast get going, (slowly) lower the temp to ><40F or 45F. > >I personnaly believe this is bad advice to those wishing to brew authentic >lagers. Yes, starting the ferment at 65F will go a long way toward >getting the ferment going, but it will adversely affect the flavor >profile of the finished product. What Jim means is that esters will be produced and you'll get the fruity flavors of an ale which you would like to avoid in a lager. >Once the ferment gets going at 65F, the >thermal energy will push the average internal temp up as much as 10F! >Unless the brewer has a amazingly efficient attemperation device, the >"lager ferment" stage would be at high kraeusen around 65-70F until the >chiller could kick in. It can take as much as three days at 49F to >reduce the temp into the acceptable range and by this time most of the >primary ferment will be complete. Also, one does not want to reduce the >temp below 48F until 90+% of the primary is complete. At this time, >a two day rest at 42F will be adequate to reduce diacetyl levels, prior to >reduction to 31F for lagering. This is another personal nit of mine that >I frequently hear homebrewers refer to a 70F diacetyl rest. This is indeed >an efective way to "rush ferment" lagers as Professor Narziss has documented >very well. But this technique is intended to produce lagers in less than 21 >days, total time! Even in this method, the primary is carried out at 55-58F >and not into the 60s. > >This is not intended to be a flame, and I think you are doing a good job >of informing the public of various techniques. I believe the attitude to >push the temperature is a result of grossly inadequate pitching quantities, >and is a poor substitute for healthy yeast. He's right. I should probably mentioned the preferred method in which the starter is slowly (to avoid temp shock) cooled to, say, 50F and pitched into 50F wort. Then you can slowly bring the temp down to the 40s if you want. Note that this will give you a much slower start than the method I suggested in my original post and therefore will require much better sanitation, but if it's lager you're after, I recommend (as Jim does) that you follow the German methods as opposed to the "rush ferments" that the American industrial giants use. Note that fruitiness is also tied to the strain and some are less fruity at warmer temps than others. Thanks Jim. Al. Return to table of contents

It's not phenolic at all >and all the flavor is a very clean fruitiness. My experience with Cooper's is that it has a distinct "bready" character. I generally use Sierra Nevada cultured from a few Pale Ale bottles. I have substituted Cooper's at times when my starter didn't make the grade. I make a house ale regularly with no modifications to the recipe unless I pitch the Cooper's rather than the SNPA. The Cooper's is much less fruity with more yeast taste or, as I said, "bready". Attenuation seems to be about the same between the two. My house ale has an OG of 1.060 and finishes around 1.018 with both yeasts. RW...

Date: Thu, 4 Mar 93 21:36:46 PST From: "Joe Stone" <JSTONE at SJEVM5.VNET.IBM.COM> Subject: All-Grain Help/BrewCap I completed my first all-grain batch about three weeks ago. Two-and-a-half gallons are now bottled. The other two-and-a-half gallons were filtered (0.5-micron "Filter Store" filter) and are now carbonating in a keg in my fridge. I sampled the beer in between the primary and secondary and it had a pronounced "grainy" taste (grainy as in grain husk). Being my first all-grain batch, I severely underestimated the heat-retention capabilities of a Vollrath pot. I combined nine pounds of grain (one pound at a time) with a steady stream of 170oF water. The initial mash temperature was 150oF. In my haste, I immediately applied heat to the mash with a 35K BTU cooker. The Vollrath pot has a SS tooled screen in the bottom. Upon applying heat, the temperature of the water/grain-dust solution below the screen increases rapidly. By the time I could thoroughly stir the mash, the temperature was at 190oF. Oops! Not only did the temperature hit 190oF, but it took a good 45 minutes for the temperature to return to the target range. I was hoping that someone could confirm my seemingly-obvious diagnosis of the "grainy" taste. I also have a question regarding sparging. I often read of two and three hour sparges. I use an elevated cooker/pot arrangement to bring heated water to the grain bed via a sparge ring. I have good control over the drip-rate. My question involves what is considered appropriate in terms of a sparge rate. With my first all-grain batch mentioned above, I "throttled-back" the flow rate using the spigot in the bottom of the pot. My objective was to sparge for one hour and collect about six-and-a-half gallons of wort. After about 45 minutes, the flow rate had reduced to a trickle (with the spigot now wide open). I would estimate that I collected about four gallons of wort. Does this seem appropriate? Should I be calculating my extraction rate? I can't imagine a better siphon-starter than a BrewCap. I took a very sharp 0.5" drill bit and drilled out the main stem of the BrewCap. There is a significant amount of excess material between the I.D. and the O.D. of the main stem. I soaked the BrewCap in hot water for a few minutes and inserted my 0.5" O.D. hooked racking tube into this enlarged stem. I slid an 8" piece of tubing over the auxiliary stem into which I simply blow. The siphon starts every time and your mouth doesn't come anywhere near your beer. js Return to table of contents
Date: 4 Mar 93 23:19:07 MST (Thu) From: rcd at raven.eklektix.com (Dick Dunn) Subject: re: Ginger beer summary Dave Whitman <rsndww at rohmhaas.com> writes about ginger... > Many people pointed out that the sweetness of the wort may be masking the > ginger flavor... This is backwards from my experience (and some cooking experience as well) - a bit of sweetness usually tends to bring out spices, ginger in particular. >...The message is that 1) lots of recipes use about 3 oz of ginger FWIW, we've used a lot more than that, and had good results. We used about 9 oz in an amber ale that turned out nicely, and about twice that in a mead. (these were 5 gal recipes) The amber ale was a prize-winner some years ago. The mead is still young, hence a bit assertive, and you need to calibrate the difference in alcohol content (meads generally being a lot stronger), but it's not excessive. Don't be too bashful! I'd say you can put half a pound of ginger in a serious ale, and a pound in a good mead. > Jim Grady suggests grating the ginger rather than slicing it. For what it's > worth, I tasted the ginger slices after boiling, and they were pretty > flavorless, suggesting that the flavor was sucessfully extracted. That's a good test, but I wonder if you may not have boiled off some part of the essence? (conjecture only) We have added ginger to the hot wort or must, then transferred it to the primary and let it stay for at least the first week or so. > Spenser Thomas warns that he tried adding pieces of ginger to each bottle, > which gave good flavor, but also caused gushing... Definitely a problem...nucleation points. Anything rough will cause CO2 to come out of solution rapidly. (It could be a sanitation problem as you suggested later, but I think not. It's just a matter of providing the kind of surface that makes CO2 bubble out.) > (another) He has added ginger to his secondary, and that doesn't seem to > help, and sometimes leads to off-flavors. He speculates the pulp rots, and > suggests I try dried, ground ginger. No, stay with fresh ginger. You lose too much otherwise. I'd suggest trying to treat it more gently--get it hot enough to sterilize, but don't boil it. --- Dick Dunn rcd at eklektix.com -or- raven!rcd Boulder, Colorado USA ...Simpler is better.

Date: Thu, 4 Mar 93 22:23:57 -0800 From: pascal at netcom.com (Richard Childers) Subject: bikePUBcrawl Despite suggestions to the contrary, I have decided to go ahead and carry out this bicycle-based pub crawl, as scheduled, this Sunday, 07 March 1993. I realize that the weather may not prove suitable but my intuition is that it will be a glorious day. Early March in San Francisco usually is. If anyone cares to skip this bicycle ride, it may happen again, if it proves at all to be successful or reasonably well-attended, in a month or so. It's also possible some other bikePUBcrawls might be scheduled, elsewhere in the Bay Area ... Those of you without the inclination to bicycle ( Russ Wigglesworth, to be precise, but surely others as well ) are welcome to meet us at the brewery, within the time range we estimate we'll be arriving within - see below for the approximate schedule. The destination is the Marin Brewing Company, 'in Larkspur, at 1809 Larkspur Landing Circle( ph# 415.461.4677)', to quote a helpful soul. ( Thanks, PDK. ) The route is described below, although it is also reachable by car as well as by ferry. ( This route is also summarized below, but I include other direc- -tions for purposes of redundancy of informedness - thanks, Paul J. ) I encourage everyone to invite a friend or three. Safety in numbers ... Here's the schedule : Sunday 1130 arrive at south end of Golden Gate Bridge, via bicycle from Fisherman's Wharf ( where car is optionally parked ), or, park on ocean side of bridge, by old WWII artillery bunkers and ride bicycle over to meeting point ( short stroll ). 1200 depart from south end of Golden Gate Bridge, meeting on the west side of the bridge ( bicycle side ) between 1130 - 1200. bring a windbreaker, a backpack, and water, of course, as well as ancillary items - tools, spare tire, pump, headlight if you plan to ride at night, etc. Over bridge, loop around to road underneath, follow around to Sausalito, through Sausalito, through Mill Valley, under 101 overpass, across marshes, to stop light at Blythedale. 1300 Depart intersection of Blythedale, negotiate neighborhood via bike path, towards and parallel to 101, over hill and into Corte Madera, to Tamal Vista Street. Follow Tamal Vista to end, turn right, cross 101, turn left, follow bike path parallel to 101, into Larkspur. 1400 Arrive Larkspur, check ferry schedules, converge on pub for cold ale and hot food. 1600 Head back to San Francisco via ferry. Windbreakers useful. 1800 Possible sunset gathering at the infamous Toronado. Caveats : - There won't be any good way to deal with dead bicycles en route, so I ask everyone to (a) determine that their vehicles are in good shape, and (b) determine how they will cope with problems if they occur ( I suggest Golden Gate Transit ). I'll have a pump but I'm not a professional bike mechanic. - Bring spare change in case you need to make calls or take a bus, as well as bicycle locks and the like. - Bring tools if you have them, between us we may be able to fix any small problems that crop up. - Mountain bikes are advised simply because they are more able to resist flat tires through their architecture, and flats are the single greatest nemisis of bicyclists. - Bring some snacks, we'll be working up an appetite ... Here's a longer but more precise explanation provided by Paul Jasper. - -- richard "It is obligatory, within the limits of capability, to commend the good and forbid evil." _Kitab_Adab_al-Muridin_, by Suhrawardi richard childers pascal at netcom.com > Richard, > > I don't know about San Rafael, but a group of us often cycle from > San Francisco to Larkspur Landing during the summer months.

I sterilize the tubes while doing the rest of the equipment, so my hands are pretty clean. If worried about contaminating the batch I sometimes hold the end of the tube in my hand and suck through my hand. I've done this much more often than we did gas as kids, and brew tastes much better.

Dan, haven't you seen the advanced copy of the 1994 AHA style definitions?: CLASSIC EGREGIOUS BEER-TYPE BEVERAGES 29. CLEAR BEER Category award sponsored by CMB, the consortium of mega brewers (current membership: coors, miller, bud, though a wannabe in Boston(tm) has applied). a) American standard clear beer--effervescent, no color, no head, no malt flavor or aroma, no fruitiness, diacetyl, or esters, imperceptible hop bitterness, flavor and aroma. Geographic subcategories: 1) Milwaukee style--low levels of PCB's acceptable, must be in a clear bottle. 2) Colorado style--should be indistinguishable from pure Rocky Mountain spring water (except for alcohol content). Not to be confused with Colorado Clear Bastardized Malt Beverage. 3) St. Louis style--should bear a striking resemblance to filtered Mississippi river water, but with lighter body and crisper flavor. b) American premium clear beer--a generally "bigger" version of American standard clear beer. Geographic subcategories still applicable. Also, look for Clear Beer Light and Clear Beer Dry for the 1995 competition. And, for 1996, or '97 should anticipated legal hassles arise, expect to see a Boston Clear Beer category, details relating to trademark restrictions and the numbers of marketing weenies and lawyers required to assist in the brewing process are yet to be worked out.

His statement is: We use the standard RIMS revisited (from Zymurgy gadget issue) and the temp control works fine. Temp readout is not working well because it is subject to some EMI (electro magnetic interference) caused by all the equipment (pump, heater etc). Our real problem is the motor control which due to its open loop nature is unsatisfactory. We are looking to implement a closed loop control using a Motorola chip TDA1185A or some other intigrated solution. How does your motor control work? Has anyone implemented a closed loop control?

The recirculating wort now flows through the screen in the middle as well as through the bottom. Since the primary goal during the mash phase is to control temperature, it really doesn't matter that the flow is not uniform through the garin bed any more. The temperature seems to be reasonably uniform through the mash, and no compaction occurs. Also, by having the return flow from the pump exit below the surface of the wort, I no longer have any foaming. That hopefully reduces HSE. At sparge time, I simply reduce the flow way down, pull the tube out, and give the mash a gentle stir. After about 5-10 minutes, the wort is running clear again. I then turn the pump off, start the pre-heated sparge water flowing in at about the same rate as the wort drains out the bottom." I've been thinking about RIMS designs for a year or so myself, and while I'm hardly a mechanical engineer, it seems to me that it would be possible and efficient to agitate the grain bed and maintain circulation, not with a pump, but with a few sources of vibration around the container, which would massage the grain and distribute the heat _very_ nicely, without the problem of aeriating the solution. - -- richard "It is obligatory, within the limits of capability, to commend the good and forbid evil." _Kitab_Adab_al-Muridin_, by Suhrawardi richard childers pascal at netcom.com Return to table of contents

I've been doing this for several years now. It takes a few hours with the lid on the pot, but the water does eventually come to a boil, and maintains the boil for as long as needed. I use the one large burner on our stove, on HIGH. This tends to heat the stove top from heat reflected off the bottom of the kettle. I've found that placing aluminum foil on the stove top around the big burner prior to brewing helps the stove to survive. Before I did this I had several pieces of the stove top flake off after brewing, so beware! ************************************ Now a question I've been meaning to ask: How do I make a beer that is, for lack of a better term, thick? The best beers I have tasted have all seemed like they have more body, or greater viscosity, than the ones I brew using a partial mash. I don't want to brew a sweet beer, so useing less attenuative yeast is out. Do dextrins add body without a sweet taste? I've tried using 1/4 cup flaked barley in a 5 gallon batch without much luck. Is carapils or one of the Belgian malts a better choice? Thanks, Steve Slade reply to: sbsgrad%sdph.span at sdsc.edu or sslade at ucsd.edu Return to table of contents

Miller has produced a clear liquid they are touting as a clear malt named "ZIMA". We've tried it and I suppose it will soon become a fad for the politically correct. Like Corona and a squeeze of lime. Yuk! Anyway, IMHO it tases like 7-Up and alcohol and, again, IHMO is not very pleasent. It reminds me of my younger days in the service when we used to mix "Everclear" (198 proof alcohol) with 7-Up for that quick buzz. In ZIMA, the alcohol tast/aroma is very pronounced as is the citrus taste. I've had one and will never (yes, I mean NEVER) have another. My son will probably like it and buy it.

I surmised that any nasties would be on the OUTSIDE of the fruit, therefore, I simply dipped the frozen cherries in very hot (212F) water, for 15 seconds. I figured that the coldness of the frozen centers would keep the pectins from setting. Well, they did a little bit, but most of the cloudyness settled out and the beer is quite clear for a fruit beer. Perhaps you might want to consider freezing and blanching like I did and then also using a bit of pectic enzyme? I'm also eager to learn about pectic enzymes, so I hope someone out there tells us more about them. I'll bet there's something in the Fruit and Beer issue of Zymurgy (sorry, don't recall which issue it is) on pectic enzymes, but I haven't had the time to read all of it. Al.

Hook a 110v cord to the element, and screw the element into the neck of the juice bottle so the element sticks out. See graphic below. Float this sucker in you pot to give the stove a help. Also useful for raisnin temperature of cooler type mash tuns. Note at 110v the element will be approx 1/4 the power rating for 220v.

IF > SO, HOW LONG DOES IT TAKE AND CAN YOU SUGGEST ANY TIPS TO SPEED THE > PROCESS WITH MY 8 GAL. CERAMIC ON STEEL POT. Before I got my outdoors propane burner set up, I used to boil my wort on a standard GE electric kitchen stove burner. I, too, was using a ceramic on steel pot. I found the burner to be most inadequate. I also found several methods to improve the situation. - To get the wort hot initially, I used two smaller stainless pots which has aluminum-clad bottoms. When the stuff was boiling, I moved it to the big ceramic on steel pot. (BTW, I still use the same pot, and am still unhappy with it. I have yet to find a place to buy a 6 gal and up stainless pot of decent construction with an aluminum-clad bottom [the aluminum transfers the heat better]). - Before I hit on the use two burners with the smaller pots idea, I would heat up the large pot faster by putting on the lid, then first placing pot holders all over the top, then secondly draping kitchen towels over that, with the towels hanging down the sides to help hold the heat in. You can tell by the sound when you need to take the lid off to avoid boil-over. It is risky until you know though, and I did create one heck of a mess before I got the system down! - If the burner does not put out enough heat to sustain a full boil with the lid off, then put the lid on between stirs after it hits the full boil. When you hear it going real good, take the lid off and stir it around for a bit. The full boil will continue with the lid off for a while, then die back down. Time for the lid again. That is all the advice I can offer you on that one. Best of luck! gdh Return to table of contents

I do the following: After sparging I stir the contents of the brew pot and take a sample of the well mixed liquid. I measure and temp adjust the specific gravity. I multiply this value times the volume in the brew pot and divide the total by the number of pound of grain. eg. an sg of 40 in 7 gallons of liquid = 280 total sg points divided by the 10 lbs of grain = 28 pts per lb. I have acidified my sparge water, verified my grain bed temp was over 150 made sure that the Corona cracked grain was not under milled and verified complete conversion using iodine tests of the stirred mash. I have not had haze or clarity problems with my beer. Sparge time is about 1.5 hours using a zappap lauter tun with a 1" false bottom.

Several suggestions: 1. Work a deal with a local homebrew shop on a used 5 gal carboy. there's an excellent shop in the area. 2. Mail order a 6 or 7 gal carboy - it's a bit more expensive, but I think Miller and Papazian recommend this size over a 5 gal. I've seen a 7 gal Italian carboy (real homebrewer's art...) for ~$25. (I use a 5 gal secondary, but a 7 gal bucket as primary) 3. Call one of the bottled water suppliers and ask for an empty glass carboy (there are a lot of plastic ones around), for which you'll be asked to pay the deposit (~$8). 4. Go to Whole Foods, or some other quality supplier, and buy a 5 gal w/water (~$15 including deposit) and use the water in your first batch (makes great SNPA if not distilled water) and the carboy is yours.
