---------------------------------------------------------------------- Date: Mon, 06 Dec 1999 19:40:11 -0600 From: Ron and Sharon <biohazrd at graceba.net> Subject: RE: RIMS and Stuck Mash I've been following the RIMS debate for a few days now and thought I would finally put in my 2 cents worth. I've been running a PBS (no relationship just a satisfied blah blah blah) HERMS for about 2 years now (I think we were one of their early customers for the HERMS) and have been brewing the best beers ever. I think I may have some useful input. 1. For a fast flow rate without compressing the grainbed....STIR. I stir the top 3/4 of my grainbed during temperature ramps and everything works fine. If the flow slows down, stir deeper. A big paddel helps. 2. I have never detected any extra "bitterness" or tanic nature to my beers. I make wine so I know what tannins are. The RIMS brews the best beers and really increases extraction. My last mash measured 92.5% efficiency, after I remembered to drain the heat exchanger. 3. A means of mixing wort from the heat exchanger and an exchanger bypass is essential to maintaining a constant temperatue in your mash tun. I can maintain a less than 1 degree temperature differential in my mash indefinately by mixing bypass wort with heated wort to an inflow temperature of 1.5 degrees F. over my desired mash temperature. Yes, I do double and triple decoctions on occasion so I know what an indefinate (infinate?) time is. 4. When using a HERMS with the heat exchanger in the hot liquor tank, a burner under the mash tun is essential for reaching mash-out. Use the HERMS to ramp up until the hot liquor is at sparge temp then turn on the burner for the rest of the ramp, just a few minutes, and keep up the flow rate if you are worried about scorching. For doing decoctions in a 3 vessel system with large capacity, the RIMS (HERMS) is the only way to go.

Date: Mon, 6 Dec 1999 22:33:28 -0600 From: "Rob Moline" <brewer at isunet.net> Subject: The Jethro Gump Report The Jethro Gump Report Paul Shick asks about his Nottingham probs.... I think your prob is with under-pitching....you refer to marginally low ferm initiation temps as well...their influence may be part of this as well... But, I think you real prob comes from the fact that the 5 gram sachet size is not the optimum for most fermentations....you state that you used more...true...but not quite enough.... The truth of the matter is that when Lallemand got into the beer yeast market for homebrewers, the adoption of the 5 gram sachet size was dictated by the acceptance of the fact that 5 grams sachets were the industry norm.... "The More We Know About Beer, The More We Realize That 5 gms Doesn't Cut It.' And as we speak, I understand that thoughts are going to alteration of the nominal sachet size...but does it matter? Not really.....if you understand that 5 gms is a marginal dry yeast pitching rate.... Your usage...6 gms in 5 gallons of 1.060, is seriously below my personal preaching.....two 5 gm sachets for 5 gallons of 1.040 (10 P) wort......once you bump up the gravity by 50 percent to 1.060...the need is greater..... And this again leads us back to the discussion of 'lag' phase.... To me, lag phase means the amount of time between innoculation and first budding of daughter cells....As opposed to most opinions that it means first sign of bubbles.... I am not surprised, nor nervous with your times......the seem to be right in the ball park...considering your gravity.....and the amount of yeast pitched.... Your reports of other activity doesn't bother me either...though as Jeff Renner notes a temp variance based on the thermal 'capacity' of a carboy....and Pete Calinski supports the ferm temp diff....both good points...and Dave Burley reports on 'glomerular' facets.... ;-) All I can say is that the majority of my Lallemand/Danstar....'dry' yeast practice is with 500 gms in 1.5 gallons of water as the re-hydrant.... at 100F... I would pour the yeast into the water...and stir the hell out of it, until it was mixed in....I have never heard of this 'let it settle' deal....and my object was to break up all the 'globs' so that all the yeast could get to the water.....any O2 stirred in...(a benefit?...who cares!)....then after 10-15/60 attemperate with chilled wort for 10-15/60 before pitching......into aerated wort.... For the homebrewer....simply take 2 sachets ...for your 'average' brew...1.040(10p) Stir into a cupful or so of 100 F H2O...wait 10-15/60.......add to an equal amount of chilled wort..stir...wait 10-15-60...then pitch..... For your 1.060 batches, I would have no hesitation to personally use 3 or 4 sachets per 5 gallons..... Zymurgy/Ray Daniels Has to be the best thing to come down the pike since Andy Walsh passed the IOB!!! Seriously, we could go into all the failings of the AHA/AOB... ..BJCP/HWBTA/HBD/Form 990's/GABF-AHA Volunteers/ETC......(All of the above were arrogant and stupid muck ups, of what should have been perfect alliances.....ESPECIALLY the F-990's!....Gee, can you say, "If YOU won't give me what the LAW REQUIRES, I'll ask the LAW to give it to me??!!) Look, lets not fool ourselves on this.....Change has been coming for some time...despite those that would say otherwise.... The fact that the membership got to elect a member of the Board last year should have been a signpost to changes........More elections are in the works.....one of the discussions at the last Nationals BoA meeting was focused on which of the board members would give up their seat on the Board, in order to make way for newly elected members... The quiet work of those like Ray and the rest of the BoA....that you never hear of....are finally paying off.....and those folks have been working for years, for no pay, to correct the deficiencies that they have seen...mostly without success...but this is changing....the appointment of Ray to the Zymurgy editorship should be ample demonstration of that..... And without being able to discuss other potential improvements to the AHA/AOB, I will say that if the current crop of new ideas being pursued come to fruition, even the most aggressive naysayers will hear that 'giant sucking sound' as scores of jaws drop so fast that tornados will be created in filling the voids. Lallemand Scholarship.... Entries are coming in...and a few enterprising members are increasing their chances of winning by being named as sponsor of newly joining members.... Remember, this is for a full 2 weeks Short Course at Siebel, along with 1000 dollars for travel and accomodations, total worth $3500. If you currently a member of the AHA, it costs nothing to sign up .... Go to http://www.aob.org/AHA/lallemand.htm for more info.... Cheers!

Date: Mon, 06 Dec 1999 21:04:30 -0700 From: Bob Devine <bob.devine at worldnet.att.net> Subject: High gravity ferments Many of the large commercial brewers produce beer through a high-gravity fermentation with a later dilution at bottling time. Does anyone of a comparison study that shows the effect of high gravity fermentation compared to constant gravity? In my home brewing I find that higher gravity will have increased ester production but lower hop efficiency. I ask because I'm considering doing a mild soon and wanted to increase the flavors in this low gravity beer. Bob Devine Return to table of contents
Date: Tue, 7 Dec 1999 07:30:08 +0000 From: William Frazier <billfrazier at worldnet.att.net> Subject: Reverse-RIMS I brew with pretty basic set-up but the recent reverse-RIMS discussion caught my eye. In my former life I worked as a research pharmacist developing formulas and manufacturing methods. We used fluid bed technology to coat time release beads that are found in all types of capsules. The process uses an upward flow of heated air, drawn through a false bottom that suspends drug containing beads in the air column, creating a flow pattern that permitted spraying the beads with polymers (to control drug release) without having them stick together. For this to work the geometry of the machine, flow rates of heated air and solution spraying had to be controlled, much like in your RIMS systems. I think the reverse-flow RIMS is a feasible way to increase liquid throughput and that some of the concerns about husk separation and tunneling can be avoided by proper design of the false bottom and diameter/height of the mash vessel. Consider designing the false bottom to have different areas of porosity so that the flowing wort does create motion of the grain bed. It should be possible to have the entire grain bed moving in a circular motion. This would eliminate any dead areas in the mash. With a tall enough mash vessel the grain bed should remain below the liquid level and the wort can decant off the top for recirculation. Of course, the volume of mash liquor might have to be too great for a proper conversion. As for me, I will probably stay with my Polarware Brewpot and Igloo Coolers.

Date: Tue, 07 Dec 1999 08:06:43 -0500 From: Terry Stinger <STINGER_TERRY at Lilly.com> Subject: Another RIMS heating design... I have been working on a new design for a RIMS heating chamber. So far this is only in the design stage. I haven't started to build it. The recent descussion regarding counter-flow heaters (which I have built, tested, and replaced - pictures available upon request). I believe Louis Bohnam mentioned a brewer that is using oil (turned out to be glycol) as the heating fluid. >From this, I was thinking about a new type of heating element. The design is quite similar to the older wort chillers, the one's with a copper coil inside of a 8" PVC shell. But here is the catch, what if the shell was filled with OIL (maybe even motor oil - very affordable) and an electric water heating element was mounted into the end of the shell. The heating element could be just a cheap one from your local hardware. I think the element would have to be the surface mount kind instead of the screw-in type. Here are some pro's and con's: THE PRO'S: 1) The heat exchange media (oil) could be controlled and maintained at a temp not to damage the wort (170'F-200'F). 2) All of the components could be assembled into a "black box" or unit. I imagine a PID controller and the two ends of the copper coil on the face and a fuse and power lead on the back. Everything else would be contained in the box. 3) The unit could be installed into a RIMS system very easily. 4) Utility requirements are only power. Either 120V or 220V. 5) Cleaning would be similar to washing out chiller. (various methods) 6) Very affordable!!! Even cheaper the a typical electric heating chamber. THE CON'S 1) Would the element supply adequate heat capacity without lag times. 2) PVC chamber probably won't take the heat. A large copper chamber could be used. May cost more! I guess the only question and/or flaw so far is if the element could supply enough BTU's into the exchange media without damaging the media or the chamber. This seems like a design worth investigating. Who knows it may turn into a product worth marketing. This is just a suggestion, so take it easy on the comments. Terry Stinger.

Date: Tue, 07 Dec 1999 14:12:29 +0000 From: AJ <ajdel at mindspring.com> Subject: Low pH/ASBC Bitterness Jim Dunlap asks about low mash pH. With water as soft as Seattle's the mash pH will be set largely by the organic acids in the malts. Dark malts contain a lot of acid and a fair amount of carbonate is required to neutralize them. Munich water contains about 6 mEq/L of calcium and about the same amount of bicarbonate (its pretty much devoid of anything else). This corresponds to about 3 mM/L bicarbonate which is 0.3 grams/L. Thus the 0.75 grams of chalk Jim used was enough to treat 2.5 L assuming the goal was to obtain Munich like water and the answer to his Question 1 ( Should I be adding more CaCO3 or less?) is clearly "more". But how much more. To start with as most of us know you can't dissolve much chalk in water (actually you can but it's an elaborate process) so the appropriate thing to do is to add it a gram at a time to the mash, mix it in thoroughly, wait a couple of minutes and repeat until the desired pH is reached. In decoction mashing the pH will drop about 0.05 - 0.1 per decoction so allow for this in setting the mash-in pH. Question 2 was "Although the dark munich acidifies the mash, did the added Ca decrease the pH further than the CO3 could buffer?". The answer is "no". Each millimole of chalk adds two milliequivalents to the total alkalinity and two milliequivalents of calcium which are able to offset only 2/3.5 of a milliequivalent of alkalinity. Thus the net gain in alkalinity is 2 - 2/3.5 = 1.45 milliequivalents per millimole. Question 3: ) Is there another salt or compound to add CO3 without the calcium? The anwer is "yes". Sodium carbonate (fly ash) is used in water treatment to increase alkalinity and is, therefore, available from shops that sell water treatment equipment (such as Culligan). Sodium hydroxide (no carbonate from this but a strong base) is also used for this purpose and can be obtained from the same source. Both are pretty strong medicine. Stick with the chalk! Question 4: ) Is there a simple "how to treat water text" or web sight that could help me? Answer "no". I do have a couple of articles which I wrote for BT which I can send you which go into some of the details of water treatment. I can pdf them to you if you like - send me e-mail. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * RE George's (nice to see you back here!) comments on the ASBC bitterness measurement: The method is certainly not perfect and this is recognized: "Method A below [the method proposed by Louis] expresses the bitter flavor of beer satisfactorily, regardless of whether the beer was made with fresh or old hops. The European Brewery Convention has adopted the 'E.B.C. Bitterness units,' determined in a similar way, as a uniform method that best expresses the true bitter flavor of beer." [ASBC Methods of analysis: Beer -23, Beer Bitterness"]. Other methods, use solid phase extraction and HPLC to actually measure iso-alpha acids. In beers made with old hops or hop extracts, measurements predict bitterness significantly lower than perceived. Method A does not suffer from this shortcoming. From this it is clear that Method A does not attempt to report mg/L iso-humulones but rather perceived bitterness. Nonetheless it is subject to interferences. In particular, as noted in the method description "...certain preservatives, such as n-heptyl p-hydroxybebzoate and sorbates, and possibly some brewing adjuncts or coloring agents, may contribute to absorbance at the wavelengths specified in methods A [the one in question] and B [an archived method]." It then goes on to say that Method A would be more sensitive than the iso-alpha acid methods and that where such substances are known to be present, checks for their effects should be done. As the gentlemen from AB are much more likely to be using the problem causing materials than we as home and craft brewers are I guess I am not too surprised that they weren't surprised. I'm not sure that spiking with standard humulones is going to be terribly informative as 25A does not really try to measure their levels. I'd hope that Beer's law would be obeyed over a reasonable range but it seems to me that a more valuable investigation would be one in which hopped and unhopped versions of the beer were brewed and their bitternesses (is that a word?) measured using the unhopped beer as a "reagent blank". Humulone standards are available from ASBC but they are very expensive. A good lupuholic will, of course, be working with beers in which the interfering substances are masked! Most measurement standards are imperfect. Much of their value derives from the fact that they are uniformly imperfect across laboratories equipment and investigators insofar as this is possible. A good illustration of how this works might be the requrements that all pilots in a geographic region set their altimeters to the same barometric pressure setting. A pilot whose altimeter reads 8000 is not really at 8000 feet but he is at the same altitude as everyone else whose altimeter reads 8000 ft. As a note to Louis: I don't think it's necessary to cetrifuge turbid beers before starting 23A. The yeast and sediments stay with the beer/acid phase. As you well know most samples of protein rich homebrew need centrifugation at the end of shaking to separate the phases anyway. On the other hand, lots of the bittering principal which is adsorbed on the surface of the yeast will be extracted as is demonstrated by comparing samples from which the yeast has been separated from those in which it has not (of particular interest in comparing crystal and hefe weizen from the same batch). - -- A.

Date: Tue, 7 Dec 1999 09:11:15 -0500 From: "Alan Meeker" <ameeker at welchlink.welch.jhu.edu> Subject: FWH experiment A couple of comments on Louis' proposed FWH experiment: 1) Isn't the whole idea behind FWH to add the hops /before/ the onset of boiling? You may want to modify the time of introduction of the hops to sample #1. 2) Why not include a sample that gets NO hop additions as a negative control. 3) It would be nice if you could correct for evaporative losses /during/ the boil as decreases in volume may be expected to decrease utilization (concomitant increase in wort SG due to decreased volume). If you don't correct for this then the control, while being boiled for exactly the same amount of time may be less efficiently utilized and the IBUs will come out lower than the FWH arm of the experiment because in the former the hops are being added to a higher SG wort. Don't know how much of a problem this would actually be, will depend in large part on the set up. Correction could be effected by occasionally topping off the boil with boiling water. 4) Before performing the IBU analysis I'd spin HARD not lightly. 5) Check the IBU levels both /before/ and after fermentation with yeast. This would give some indication as to whether any IBU differences seen in the FWH arm were being mediated by the activities of the yeast. 6) It might also be good to see if there are any other differences between the resulting beers other than just the IBU measurements. As far as I know the main rationale for FWH is that there is some "magic" that takes place resulting in a final hop character that is superior to standard hop schedules. In the little reading I have done and the posts that crop up on the HBD it seems that this claim is controversial. What's your take on this aspect of FWH Louis? P.S. if you eventually want to run such an experiment let me know, I'm happy to help out... Alan Meeker Baltimore, MD Return to table of contents
Date: Tue, 7 Dec 1999 09:05:21 -0600 From: Lou.Heavner at frco.com Subject: Re: RIMS comments; especially reverse RIMS Martin Brungard" <mabrungard at hotmail.com> discusses a reverse RIMS design and asks for comments... {snip} I'm in the process of creating a RIMS and my system could easily allow me to reverse the flow through the grainbed during mashing. All I need to do is change the flow outlet fixture sitting on top of the grainbed into a filter style inlet/outlet. I'm using stainless steel hose reinforcement as the filter under the grainbed, so I'll just add another one on the top of the bed to filter the wort during the reverse flow. Lautering will still go in the normal downflow direction. Unless someone can see a reason why using a high rate upflow through the grainbed would be bad, I'm going to try this idea. {snip} Not to discourage you, because you ought to try it, but remember that the grain bed acts as the filter. The false bottom or "easymasher" style screen is merely a support for the grain bed. And with normal (downward) filtering, gravity is working on the bed. I can imagine you would have a lot of cloudy, hazy type particulates suspended above the grain bed when doing reverse flow which would pass through SS hose reinforcement "filter" and end up at the bottom of the grain bed where it will be trapped. Now I wonder how you will recover all the wort without switching direction. If you do, it may take some stirring and/or considerable recirculation to re-establish your filter bed in the correct direction. And of course, you still need to make sure you are set up to prime your pump. Cheers! Return to table of contents
Date: Tue, 7 Dec 1999 10:40:00 -0500 From: Dave Burley <Dave_Burley at compuserve.com> Subject: Foam Fineness Brewsters: Jeff Renner states that artificial carbonation versus priming carbonation will give the same result in foam fineness. Others have periodically stated otherwise, opting for the "natural" priming or kraeusening method, even in kegs to produce a fine head. I have noticed that quite often naturally carbonated beers in my kegs have a finer foam and assumed it was the presence of the small amounts of yeast ,in the clear beer acting as a "boiling chip" to provide surface for the CO2 bubble to form. On the other hand, very yeasty beer often has large bubbles and often a poor head as a result, in my experience. One might conclude the opposite situation given the above "boiling chip" analogy. It is perhaps the youth of the yeasty beer that may also affect the bubble size. Or it may be that so much yeast is there that the CO2 is more rapidly brought to equilibrium and the bubbles coalesce as they are formed. This may say someting about filtered beers, and head fineness and stability, I don't know. It is an experiment which could be easily tried if you have a filter. Just filter half of the beer and compare the two kegs periodically over time. It may be that the best head can be obtained by blending filtered and unfiltered beer. I have never done a controlled experiment, but I have noticed that shortly after carbonation ( a day or so) the artificially carbonated beers have a rough coarse foam which eventually ( a week or two) will approximate the fineness of the naturally carbonated beer. It may be that the CO2 needs to be somehow complexed or it may be that the week or two will allow more particles to fall out and improve the head. The waiting period is demanded for those using natural carbonation methods, so a direct comparison cannot be made except at long term hold time. I believe the conclusion would be no difference, as Jeff states. I think there is a difference in these two methods of carbonation, as it relates to head formation and fineness but it is temporary. - ------------------------------ Keep on Brewin' Return to table of contents
Date: Tue, 7 Dec 1999 10:06:37 -0600 From: "Jack Schmidling" <arf at mc.net> Subject: Beer and eggs I had to add beer to the subject so I could continue this thread here. I have finally discovered a trick that works for flawless and consistant peeling of eggs. Nothing else I have ever tried worked very well, if at all. This works 100%, even with eggs layed the same day. As a point of interest, if you refrigerate fresh eggs for a month or two, they do peel much better. That says more about how fresh supermarket eggs are than it does about peeling eggs. That is not my secret. I put the eggs in a veggy dehydrator overnight and then boil them. They peel like latex gloves and it makes no difference how old or fresh the eggs. I expect rousing cheers, kudos and a flood of donations to the Schmidling Think Cup (it's too small to be a tank).

So I will try again: I did have the opportunity to observe a RIMS system where circulating was done with a long stiff rod of copper tubing with a right angle at the bottom, the end was flattened causing a jet stream of good velocity, when circulation was started the mechanical action stirred the whole mash up nicely, by being close to the bottom it tended to lift and move all the grains and acted like a great stirrer, and full open valves were used with plenty of circulation volume. I just must try this myself soon, not much needed except a piece of copper tubing. If it does not work, I can just switch to my normal downflow device and continue.

Date: Tue, 7 Dec 1999 14:26:01 +0000 From: "Jim Busch" <jim at victorybeer.com> Subject: Budvar malts & philosophical rants To Lynne of St Pats, what I wrote was not intended to "sting" and since it seems that it did I want to publicly apologize for so doing. After some 10 years on the net it is still helpful to recall how harsh the printed word can seem when read without the emotion of a human face. And of course we are all busy and email is a vehicle whereby we can easily jot down a few statements and send them off before realizing how they will be received on the other end. Im also glad to see that there are still homebrew/pub/micro retailers who take the time to remain connected and post valuable information on the net. One persons piece of info is anothers spam so its easy to see why some responsible folks just dont bother. Wholesaling and retailing (especially retailing at the homebrewer level) of malts must truly be a labor of love and I applaud St Pats and others for doing so. I can only imagine the overseas ordering hassels and duties, shipping containers coming in to port needing to be warehoused and then repackaged into tiny homebrewer quantities followed by the incessant repetitive questions as to the nature of the product. Many would just relegate this to others and serve the largest volume customers who dont ask all the questions that can be learned from a good textbook. Sometimes its useful to recall that before the advent of computers and instant personal interaction there were actually libraries and folks who used them! Shocking thought I know in this world of interconnected web sites with vast arrays of information some of it thinner in depth than floor maltings in England! But as Jackson is want to say, I digress. <out of a molehill? Narziss has noted the decline in 'liveliness' in <German beers over the past couple of decades. Narziss attributes <this defect to brewers failing to compensate for modification in the <malthouse vs the brewery. Absolutely and one of the reasons German brewers I talk with wont dough in below 57-60C if using standard highly modified malt. FWIW, Im a firm believer in decoction mashing for some beers and some malts. I also firmly believe that it makes a significant difference on the end product, no matter what some West coast authorities may proclaim otherwise. Id love to see another go around with that mashing (RIMS/step vs decoction) experiment Louis did for BT. That would be great material for Daniels to cover in both The New Brewer and Zymurgy, IMO. 15P Maerzen biers, 13P Exports, 10 and 12P Czech pils, 14P Dunkles.....all are beers that benefit from decoction mashing of imported malts with lower than typical modification. Yes it takes longer in the brewhouse, yes it costs more to have a mashing system to handle it, yes it leads to more protein stability issues in the final beer, yes it darkens the wort and increases melanoiden formation. Yes it makes a difference. Its not so difficult for the experienced brewer to make good beer, its very difficult to consistently make special beer, beer that rises above the ordinary where the marriage of these simple ingredients form a much greater whole, the magic of the symbiotic nature of these blended processed base materials, the art of the brewmaster.

Narziss attributes this > defect to brewers failing to compensate for modification in the malthouse > vs the brewery. I agree that it is great to have something to experiment with. That is the beauty of homebrewing. Money really is not a big concern. For once we can answer the above questions and find out if all the high intensity mashing schedules of years past etc. really make a difference. I fail to understand the statment "Are those that promote the importance of multiple temperature rests regardless of modification..." I thought this was largley dead. Modified malt does not need a protein rest. Based on the malt analysis 9if you have it) you may need to do a glucan rest. and the alpha and beta rests cna be used to determine fermentability. Maybe Narzizz is experiencing the effects of ageing and simply waxing eloquently for the past. Does he provide analytical data to support his feeling? And after all most german brewers are using completely different modern equipment than what was used years ago. And simply because brewers are no compensating does not mean they should go back to using undermodified malt. > regardles> > These are just a few of the fundamental questions and issues that > undermodified malt relates to and this is why I believe it is the most, for > lack of a beter word, important new product. > more like "newly available to the amreican brewer". :-) > The issues that drive modern brewing research are primarily those of shelf > life, extract efficiency, and time and labor costs in both the brewery and > malthouse.

With the expansion of the EU this kind of business practice can not go on. The bean counters will step in. There is already backlash against the Velvet Revolution. As sales grow they will need to resist the tmeptation to expand etc. Can they keep this up with rising energy costs, wages, health care etc?

It would be great if all the info one sees on a malt analysis done by Seibel for example, were available. This would provide brewers with th info they need up front to deal with a given malt, regardless of mdoifcation. Sure the real test comes when one brews with the malt using their system. But as homebrewers we don't have the luxry of buying a train load of malt and then doing a test batch, analysizng the resulting wort and making adjustment accordingly. I can just see some one getting this undermodified malt, mashing with it and not using proper temp rests and then having the lauter from hell. Then they'll say this malt sucks and St Pat's is selling crap. Jim Liddil Return to table of contents

I found this at approximately the time that my copper, home made chiller got a serious crack in it. I will likely buy this (correction, my brother, good soul that he is has offered it as a present) but wanted to know if anyone thought it was a bad idea based on the ability for SS to conduct heat and therefore function as a good immersion (or counterflow) chiller.

No, In fact for about four years I make tow lagers two weeks apart. The first uses newly purchased yeasts. After about 10-13 days of primary fermentation, I transfer to the secondary and wash the yeast for the second batch. Since I have one freezer the first batch is usually at 50 - 55F for 4-5 weeks until the second is transferred and I bring the freezer down to 35F in three weeks time. Then I lager for 3 - 8 weeks, depending on when I can bottle. >After lagering for 2-3 months, will there be enough active yeast leftover to >carbonate with corn sugar? Will I need to add a secondary yeast? Am >planning on having kegging capacity by next month, which will probably help >me in that dept. I have absolutely never had a problem. Although it takes twice as long to carbonate than an ale. There are two possible explainations: 1) At 35F CO2 is much more soluable, so I have actually found the beer slightly carbonated at bottling. 2) I always hit the bottom of the secondary once or twice to stir up a little yeast when racking to bottle.

There are: Chain brewers - brew almost weekly Binge brewers - I go months without seeing them, then they are in twice a week for a few weeks Social brewers - only brew with buddies Prohibition brewers - I don't like to think about them Spectator brewers - not really brewers per se, but they like to watch Technobrewers - believe that beer cannot be made without control to the n'th degree Burnout brewers - used to brew and know a lot about brewing, but "can't seem to find the time now" Mental brewers - draw up recipes that will never be brewed I am more than open to other suggestions!

Date: Tue, 7 Dec 1999 21:02:12 -0600 From: "Sean Richens" <srichens at sprint.ca> Subject: Scott's temperature conflict I can understand Scott wanting to have both really low lagering temperatures and reasonable fermentation temperatures, but don't forget traditional (=commercial??) practices vary a whole lot. I found that 50-55*F is a good compromise for primary, secondary, and lagering. I had no trouble with bottle priming in this range; rather the slow priming helped consume all those sulphury compounds some of the lager yeasts make. There's a sentence somewhere in Noonan to justify this. Since I use the big walk-out refrigerator with the blue ceiling and the white carpet to cool my brewing room, I don't have much choice. I put the lagering beer closest to the window but I'm probably kidding myself. Sean Return to table of contents
