Is that not needed for this yeast/ this style? I am basically following the description in Papazian,...adding some fresh lager yeast as it goes into secondary...new to me...but wonder, is a diacetyl rest called for? Kolsch is not a lager, it is a German ale, just like Alt. Both are top fermenting yeast fermented at temperatures lower than most ale yeasts, and neither one requires a diacetyl rest. From my experience with that yeast, you will get a sulfury smell after primary, but lagering for a few weeks gets rid of this. Between primary and lagering, a diacetyl rest is not needed.

You should be commended for how well you take it. My only question is this, Do you own a Homebrew Supply Store? Because seriously, it all ads up! Liquid yeast and top of the line equipment is all stuff a person who owns a store would promote.

Had that problem myself on my first few grain batches. The single biggest difference any one change made in the end was changing the settings on my grain mill to get a better crush. Some people run their grain through their mills twice, if the mill itself is not adjustable. I went from averaging 55-60% efficiency to brewing an 80%+ efficient batch, and a ~70% batch after that. Big difference. I'll be brewing again this weekend, and will see if the higher efficiencies are repeated again. So try crushing your grain twice through the mill, and see what happens. At worst you'll waste a little time doing the second milling, but at best you may solve your problem. :-) - -- ::Teresa : Two Rivers, Alaska:: [2849, 325] Apparent Rennerian "It has been my experience that folks who have no vices have very few virtues." -- Abraham Lincoln Return to table of contents

Steve, I don't think you will notice any difference in the taste of your finished beer, especially since it looks like you are making something rather dark and not a pilsner. I believe the major disadvantage of letting crushed grain stand around for a period of time would be an increase in moisture content which could affect extraction rate. I believe you have had a lot of rain in your area recently, but if the grain is sealed up well it shouldn't be a problem. I know a brewpub brewer who gets all of his grain precrushed in 50lb bags from the malting company and he makes some outstanding beer with it. I am sure that the grain is very fresh when he receives it and that he is careful to use it quickly, but there doesn't seem to be any problem with it. Dan Gross Olney, MD Return to table of contents

I have several stones but occasionally I need to get one out of a part filled keg. It's not really a big deal and goes something like this. Put a rubber glove on the hand that is delving into the keg and dip it in your sanitiser, gently de-gas the keg, rip the lid off grab the stone ,re-seal and re-gas. you don't lose any carbonation and the outgassing of the beer should keep any bugs out. However opening a keg is a risk and I try and avoid doing it until at least 1/4 has been used to avoid touching the beer. Cheers, Reuben W.A. Return to table of contents

Try putting the primimg solution in the bottling vessel before racking in the beer. This will better disperse the priming solution throughout the beer, which will give you more consistent carbonation, and avoids stirring which will cause oxidation problems.

Date: Thu, 27 Feb 2003 05:10:05 -0800 (PST) From: David Passaretti <dpassaretti at yahoo.com> Subject: RE: temp probe placement Someone mentioned that there is no point in using a bypass loop and in mash systems and that the the probe needs to be close to the heat source. I use a HERMS with a PID controller and two solenoid valves in the flow loop. When the PID wants to add heat it opens one valve and closes the other to send wort through the heating coil in the HLT, when no heat is needed the valves are in the oppsite configuration and the the wort flows through the bypass. With the HLT is only 5-10 degrees above the mash temp there is no concern for overheating, denaturing, or hot spots and the wort can continue to recirc the entire time to ensure even grain bed temps. My RTD is located nera the bottom of the tun, almost as far away from the heat source as possible (by convenience not design). This does build a large lag time into the system, but then again that is the entire point of using a PID controller. They are designed for accurate temeperature control when the system has a long lag time and and/or a large heat sources (as is the case with a HLT). Using the autotune feature, my controller set its own values and now keeps temperature within 1F with rapid ramp times if needed, continous recirculation, and no concern for overheating. Bypass loops and probe placement my be of concern in RIMS or in systems without PID control but not in a properly built and tuned HERMS. David Passaretti Return to table of contents
Date: Thu, 27 Feb 2003 04:46:13 -0800 From: Jonathan ROyce <jonathan at woodburybrewingco.com> Subject: re: How Long will crushed grain last? Steve Tighe wonders if crushed grain will last a week and if his starter will still be good to go on Thursday or Saturday. I'm sure your going to hear everything from a resounding YES to a condemning NO on both points, but WTH, I'll chime in. I crush my grains at the LHBS and (occassionally) I buy grain via the internet and have the vendor crush it for me. In either case, I store it in plastic bags and throw the plastic bags in a sealable rubbermaid container for good measure. I've never had a problem with a week or a week and half of storage. (In fact, when I buy via the internet, the grains are usually in transit for a week anyway.) I think a pretty good comparison is coffee. Surely when you grind your own beans every morning, the aroma is stronger than when you open your can of Folgers. However, do you really notice a difference in the taste of the BREWED coffee? I don't think I could tell the difference in a blind taste test. I'm sure that true "connoisseurs" *claim* that they can. Some of those probably even can. As for the starter, you could take it out of the fridge, decant the liquid and let it warm up to room temp while you brew, then pitch it. Or do steps 1-3 the day before, add some wort and let it take off again, then pitch it on brew day. IME, you'll probably get a quicker start if you get it fermenting again (option 2), but even if you don't, you'll probably have fermentation within 8 hours or so. Keep in mind that option 2 adds one more chance of infection, so you'll have to weigh the risk and reward and decide for yourself.

Should I find another way to dispose of the sanitizer? >How do you deal with this? Stuart, This question comes up every now and then. My recollection from past discussions (you may want to read through the archives for more info), is that there is not generally thought to be a problem. I can only speak from my personal experience of brewing with a septic system for the last 10 years or so. Although I have brewed infrequently over the last several years, for the first I 5-6 yrs I brewed very often. I have had no problems whatsoever, so I can only assume that there is no significant impact on the septic system. FYI all gray water also goes down the drain as well. I would expect to have more impact from the volume of laundry/dishwasher detergent, etc, than from the small amount of brewing waste water. Scott Brewing in Columbia, SC Return to table of contents

Date: Thu, 27 Feb 2003 05:40:47 -0800 From: Jonathan ROyce <jonathan at woodburybrewingco.com> Subject: re: Question on grain utilization Andy Mikesell asks about grain utilization: I've had some similar issues with my partial mashes and here's what I've been paying attention to, with some success: 1) The crush. I suspect that this is my biggest problem. After my sparges, I always chew a bit of grist to see if it is sweet. Two times ago, it wasn't--my extraction was great. Last time (a hefeweizen) it was sweet. My efficiency was back down around 60%. It seems that especially recipes with small grains (like wheat malt) are problematic. I am going to start double milling my grains to see if things improve. 2) Do a mash out. My LHBS owner suggested this. It may be helping, but it certainly can't hurt. The theory is that the hotter liquid is less viscous and the sugars are more easily extracted. 3) Make sure you sparge to completion. I have done a batch where I got lazy and rather than measure the gravity of the exiting wort and stopping around 1.010, I just went by a volume that "felt right". In fact, it wasn't right and I didn't extract everything that I should have. As for adjusting the grain bill, don't adjust by subtracting your actual efficiency from the expected and then increasing the amount of grain by that percentage. Instead, calculate the ratio of expected to actual efficiency and increase the grain bill by that proportion. In your case, 0.700/0.585 = 1.197, so you should use approx 1 lb 3 oz of grain for every lb (0.197 lbs = 3.15 oz) required by the recipe.

Date: Thu, 27 Feb 2003 06:00:17 -0800 From: Jonathan ROyce <jonathan at woodburybrewingco.com> Subject: re: Weight Watchers and Homebrew points Andy Mikesell asks about Weight Watchers and Homebrew points: I don't know about WW "points", but I think I can help with the calorie value. You'll need to data points: FG and ABV (or OG, from which you can calculate ABV). For an example, I'm assuming 5% ABV and FG = 1.016 Now, let's take the following constants: ABV to ABW, multiply by 0.8 calories/gram carbohydrate = 4 calories/gram alcohol = 7 Two assumptions: (1) specific gravity is the same as density (which should be pretty accurate) (2) all excess carbohydrate is digestible by the human body (down to S.G. = 1.000) So, let's say we have a 330 ml volume of beer. It weighs: 330 ml * 1.016 = 335.3 grams If all of the weight above that of water & alcohol is carb, there's: 335.3 grams - 330 grams = 5.3 grams carb The alcohol by weight is: 330 ml * 0.05 * 0.8 = 13.2 grams alcohol So the caloric content is: (5.3 grams carb)(4 cal/gram) + (13.2 grams alcohol)(7 cal/gram) = 113.5 calories That's probably a pretty good estimate. Any out there have any suggestions for improvement? Hopefully weight watchers has a conversion of calories to points? I'm not sure how that system works.

Date: Thu, 27 Feb 2003 06:19:33 -0800 (PST) From: "John B. Doherty" <dohertybrewing at yahoo.com> Subject: RE: Thinking about a Kolsch Darrell, I often find myself thinking about Koelsch! :) First, to answer your immediate question, I have never done a diacetyl rest for a Koelsch. I ferment my Koelsch under 65F, preferably at 60-62F, well oxygenated with a large starter. I have more experience with Wyeast 2565 than with White Labs (029 is it?) (6 Koelsch + 3 Alts with Wyeast, 1 Koelsch and 1 Alt with White Labs) and when tasting at racking I've never detected diacetyl in any batch. Before I forget, do yourself a favor and brew an altbier a couple of weeks after the Koelsch, re-using the yeast again at 60-62F. You'll want to cold lager both these styles for 6 weeks or so near 32F. I lager in one corny (with 1" cut from the liquid diptube) then transfer with CO2 to another corny with a Liquid-Liquid jumper line I've made. Force carbonate, and you'll have a crystal clear keg you can bring places without fear of it getting un-Koelsch like from stirred up sediment. Ok, About your grain bill - one problem, one concern, and one suggestion: The problem - I wouldn't use Munich Malt in a Koelsch, and if I did, it wouldn't be at 12.5%. I'd maybe throw in 1/4# of Munich for a maltiness contribution, but Koelsch doesn't need much maltiness, and what malt character it does have should be quite soft. I use 1/4# of carapils (carafoam, carahell - The lowest color caramalt I can get) myself. Save the Munich Malt for an all Munich Malt Altbier! The concern - when you say 2-row, I'm hoping that you mean a nice continental 2-row pilsner type malt with a very low color (2L-2.5L). Anything darker will make an uncharacteristically "dark" Koelsch. The suggestion - I'd up the wheat content just a little bit. I've optimized my Koelsch recipe at 15-16% wheat malt. At MCAB5 two weeks ago, we got to sample some of brewer Bill Madden's (of Capitol Brewing Company in D.C.) GABF Gold winning Koelsch, which was fabulous (although a touch over carbonated at first). Bill's preferred wheat malt content is 18%. Don't get me wrong, 12.5% will make an excellent Koelsch (I've brewed with as low as 10% and as high as 20%), but you won't be disappointed with a little more wheat. And regarding the mash - I'd recommend skimming Warner's Classic Beer Styles Koelsch book and trying a multi-step mash (if your system allows it). I seem to recall using a quick "high end" protein rest, infusing to Beta, infusing to Alpha, and infusing/heating (SS mash tun) to mash-out. Oh, and start the mash thin - 1.5 quarts/# and through the infusions, you'll end up closer to 2.5 quarts/# in the end. Keep your boil short (60-75min) and use a light hand with the hops (low alpha varieties). I like Hersbrucker, Tettnang, Spalt, and Perle, (those last 2 are often mid-alpha 6-8%AA) and tend to vary the variety from batch to batch. I don't much care for Saaz in my Koelsch, especially for late additions, since to me Saaz really stands out and is reminiscent of a Czech beer. But to each their own. Have fun brewing this one - Koelsch is such a wonderful style! (and about as far from an Eisbock as you can get) :) Cheers, John Doherty Lakeville, MA =========================================================== On Tue, 25 Feb 2003 17:09:03 -0500, darrell.leavitt at plattsburgh.edu wrote: Subject: Thinking about a Kolsch I am thinking about a Kolsch, using WL German Ald/Kolsch yeast...and have looked at Papazian's HOMEBREWERS GOLD, p 180-181, description of Stoddard's Kolsch,...and wonder...they have no diacetyl rest.

Date: Thu, 27 Feb 2003 06:45:17 -0800 (PST) From: Roy Roberts <psilosome at yahoo.com> Subject: mixing priming sugar Bruce Bush asks about uneven mixing of priming (finishing) sugar. About two years ago I found a nice method on someone's homebrew site (sorry no reference) which I use every time I bottle. It does require a bottling bucket (I use my plastic hot liquor tank) but otherwise is very simple. The priming sugar is boiled in a small volume of water to sanitize, then put in the sanitized bottling bucket with sanitized racking tube and cane attached. Allow the liquid to flow into the tube/cane and then close the spigot to trap the liquid. Then lower the bottling bucket and put the racking cane into the fermentor. When the spigot is opened the sugar solution will fall into the bucket and start the siphoning process. In my experience this gives very even mixing. Roy R.

Always a good idea to pitch more yeast rather than less (within reason), and recently fed yeast, so I'd say decant and feed. If you give it some low gravity wort, it will ferment out quickly and be ready to decant again, so you aren't pitching spent starter into your precious wort. 50 grams of dry extract in a liter of water will give about 1.019. This is what Dan McConnell of the late Yeast Culture Kit Co. recommended, along with 1/6 tsp yeast nutrient. This works well for me.

Wheat (39) and 4 lbs. >Cara-pils Belgian (34) Are you saying that the grain bill of this kit was just these two grains? That is a peculiar bill - cara-pils is no a base malt but a kind of very pale crystal and is normally used at less than 10% to build body and foam stand. 34 ppg seems high in general for this kind of grain, but maybe it's right. What's more, since wheat has no husk, this mash could cause runoff problems. Perhaps you had channeling (no, not from King Harubi of ancient Mesopotamia, channels through the mash that bypassed the grains). This could reduce your extract. How was the crush? Was the grain precrushed by Northern Brewer? If so, I am sure it was a proper crush. If not, perhaps you did not crush it fine enough. This is a common cause of low efficiency. >Should I make up the difference will DME (something I'd rather not do)? 1.041 is not terrible, but depending on the style, the beer may be overbittered for that gravity. I've certainly covered mistakes with a little DME. If you are adding it late in the ferment, be sure not to introduce oxygen.

Date: Thu, 27 Feb 2003 15:41:32 +0000 From: AJ <ajdel at cox.net> Subject: Free Advice Herewith is my take on Patrick's water. Keep in mind that free advice is often worth what you pay for it. The water has 36 mg/L calcium which translates to 1.8 mEq/L. It has 7.5 mg/L magnesium which translates to 0.6 mEq/L. Its alkalinity is 85 mg/L or 1.7 mEq/L. As this is less than the total hardness (2.4 mEq/L) there is some permanent hardness to the tune of 0.7 mEq/L or 35 ppm as calcium carbonate. The associated anions are probably chloride and sulfate. The residual alkalinity is 1.7 - (1.8 + 0.3)/3.5 = 1.1 mEq/L or 55 ppm as calcium carbonate. This is marginal and suggests that some means of lowering mash pH (addition of gypsum, the use of some dark malt, decarbonation or the addition of acid to the mash) would be beneficial though most styles of beer can probably be successfully brewed without any treatment. And yes, charcoal is effective in removing chloramines so long and the water is in contact with the charcoal long enough. If you can't smell it in the output water you are generally OK. A.J.

This is another one of those instances where you slap your forehead and exclaim "Duh! Why didn't I think of that before!?!?" I've got a slotted copper manifold attached to a bulkhead fitting/ball valve in a mash/lauter combi-tun that is direct-fired. It works well except that the manifold makes stirring while heating a little more of a pain. (I have an intense fear of scorching the mash while heating.) Seems a DIMS would be a nice alternative and very convenient for brewers who are reluctant to cut holes in their kettles for drain ports. I do have one question though. Does the DIMS require siphoning to start the flow of mash liquor? If so, how convenient is this? I'm imagining starting the siphon by mouth and getting a mouthfull of very hot wort if one isn't careful. Ouch! I read the HBD regularly but never get around to posting. I'd just like to say thanks to everyone for contributing ideas here. I've gotten alot of very useful information from this valuable resource.

He is wondering about the adequacy of the information. All he could gather was Ca, Mg, Hardness, and Alkalinity information. With just that information, it appears that the water is fairly well suited for brewing, barring some other ions in excess. It appears that the calcium, magnesium, and hardness numbers correlate. The hardness calculation is: ((Ca/20) + (Mg/12.15)) * 50 , all the input and output are in ppm. mg/L is the same as ppm. The alkalinity is looking good at 85 ppm. When compared to the hardness, it puts this water in the range of about 50 for Residual Alkalinity (RA). Ideally, having a RA of 50 or less is preferred when using lighter colored grists. It appears that the water is probably a good base water for most beers, especially darker colored grists. Styles like pilsners may need just a bit of help, the water is a little too hard. In my opinion, it appears that a few drops of acid per gallon would probably drop the RA into a more favorable range for pilsner. I'm not sure that softening the water would really be needed to make a decent pilsner with that water. Adding gypsum, epsom salt, chalk, or calcium chloride will harden the water, again bringing the RA into a more favorable range for styles that can use harder water. I'd say increasing the calcium concentration in this water up to about 100 ppm would be about the limit without requiring an increase in alkalinity. The main deficiency in the water data is the lack of information on sodium, sulfate, and chloride content. I consider these ions the beer flavoring constituents. I recommend calling the water company back and asking specifically for these three ion concentrations. I think they will provide the data if they know what you want. With regard to chloramine removal, I do believe that carbon filtration will strip the chloramine. Martin Brungard Tallahassee, FL Return to table of contents

You may not be aware.. There are some professionals (some brewpubs are a good example) that order pre-crushed malt. It surely takes more than a week to get to them. They successfully produce beer from it. How long should you expect it to be good? I don't know, but you should be OK for a week or two. - --------------- Yes, I have relocated.

For most brewers, you will have one temperature controller that controls a heater (RIMS or HERMS) based upon a signal from a single temperature probe (thermocouple, RTD, etc) located somewhere in the recirc loop. In a system design like this, the rule is that the farther the probe is placed from the source of heat in the direction of wort flow, the larger the temperature fluctuation you can expect in your mash." I have placed my temperature probe at the mash tun outlet on my system because the temperature of the mash is what I want to control. I also have a dial thermometer at the heater outlet. In actual practice ( 70+ brews), I see no more than a 3 to 4 degree temperature difference between the heater outlet temp and the mash tun outlet temp when ramping temperature ( heater duty cycle = 100%). Once the temperature of the mash is within the proportioning band of the controller, the temperature difference diminishes to zero as the system reaches setpoint. I have found that the critical parameter in maintaining the small temperature difference during temp ramps is maintaining a proper flow rate through the grain bed. With a properly tuned controller and the correct flow rate you can hit your setpoint with no overshoot or oscillation and maintain your set point within one degree. However, if the wort takes too long to cycle through the system due to grain bed compaction or pump inlet clogging from grain particles, feedback to the PID is delayed and local overheating is a consequence. Good flow rate can be assured with proper crush of the grains, good false bottom design, and correct grist to water ratio ( I use 1quart per pound plus one gallon to fill the area under the false bottom and the system piping).

I don't know what the 2 row you refer to but it should not be Pale malt, but rather a Pilsner malt. You should also drop the Munich malt and just up the Pils malt by a pound. This style should be very light gold in color and IMHO the Munich would take it out of style for color (depending on the oL of the Munich malt) and flavor. The Kolsch is a very delicate, soft beer. A specific diacetyl rest shouldn't be necessary since the fermentation takes place at the low end of the ale temperature range. The yeast should re-absorb the diacetyl it's produced. You could even go lower than 60, say to 55oF. Ferment at this temperature until it's fully fermented out, say give it 2 weeks; that will give the yeast plenty of time to complete the fermentation as well as re-absorb any excess diacetyl. Then rack and lager for 4-6 weeks at 32-35oF. No additional yeast is needed in the secondary. But you may need to add yeast at bottling if you've managed to settle out most of the yeast. Either add or just suck up some of the settled yeast when you rack to the bottling bucket. Good luck. Dave Houseman Return to table of contents

Could there be >contamination that spoils the carbonation and head? Is there a foolproof way of >mixing in the finishing sugar syrup? Thanks for your feedback. Stirring as you state "for quite a long time" is not a good idea. By doing this you are letting more oxygen make contact with your beer which is not good. All I do is boil my sugar water solution for 5 minutes, let cool slightly and then dump into the bottom of my bottling bucket. Then siphon your beer from the fermenter to the bottling bucket making sure your siphon tubing is at the very bottom of the bottling bucket when the siphon starts. This will prohibit splashing and such that would also oxygenate your beer. The siphon action alone will be enough to mix the sugar with your beer. I have used this method many times and never had the carbonation problems you speak of. Exactly if oxygenation would give you these problems, I do not know, but stirring for quite a long time does not sound like a good idea to me. Paul Romanowsky Return to table of contents
