---------------------------------------------------------------------- Date: Fri, 19 May 95 10:19:34 EDT From: Steve Robinson <Steve.Robinson at analog.com> Subject: Fix mash schedule/EasyMasher<tm> Russel Brodeur writes, regarding the Fix mash schedule: > It seems to me as though the rest at 140 F does virtually nothing at all, > and the entire conversion is taking place at 158 F, hence the high FG's. > This is the logic which prompted me to increase the 2nd rest to 145 F. I also use the Fix mash schedule, and have been very pleased with the results. I do not experience the high FG problem that started this thread, and I think it's important to understand one of the main advantages of this schedule. The degree of fermentability of the wort can be controlled by changing the times spent at 60C and 70C (140F and 158F). To make the wort more fermentable you should spend MORE time at 60C and less at 70C. My most recent experience with this is a porter which started at 1.055 and finished at 1.012. The mash schedule was straight from Dr. Fix's post in HBD #1506 (30 minutes at 60C, followed by 30 minutes at 70C). To make a wort with a lower FG, I would adjust the times to 40 minutes at 60C/20 minutes at 70C. This leads me to wonder if perhaps your thermometer is reading too high? If your 140/158 rests were really at 136/154, then the initial rest may be doing very little. You would then be following it with a short saccharification rest at 154F, producing a dextrinous wort. This would also explain why boosting the 140 rest to 145 helps. Andy Donohue writes: > There have been a few posts lately about trub removal and > hops clogging CF chillers.

I use an immersion chiller, and the one time I tried this the EM plugged up and I spent half an hour rubbing the side of the screen with a spoon in order to keep the flow going. I have also heard several other instances of the EM clogging up with hop residue and trub, and the common denominator seems to be immersion chilling. I still use the EM in my mash tun, but in the boil kettle I have replaced it with a copper ring drilled with zillions of small holes and I have had no clogging problems since.

What happened, and will this go away with time? <<<<<<<<<< Same thing happened to a batch of California Common I made recently. I believe it was due to having too high a PH level in my sparge water, but as you didn't say whether your's was an extract or all grain brew I don't know if this is your problem. Also, I had split the 5 gal batch between two pots on the stove and while I was cooling one, I believe the finishing hops in the other had more time in the wort than they should have, thus contributing more bitterness than planned. In any event, I couldn't even drink the first bottle at two weeks, but after a month the bitterness was down considerably. After two months it was outright delicious. And I'm saving the last bottle for a special occasion :-) Hope this helps! Pat Maloney Return to table of contents

Sapsis" <dbsapsis at nature.Berkeley.EDU> Subject: Drakes/Stout Dispense Top of the mornin' to y'all, Glen asks about parameters for Drake's Ale: For those regionally interested I can give some insight, although I believe that Roger has altered the recipe somewhat since I saw it brewed. The beer is kindof a hybrid between a big british brown (?) and an old ale. The is a distinctive caramel malt character coming from the use of medium dark british crystal (80 Lov H. Baird) at about 10% of grist. The balance of the grain is (was) Great Western 2 row. Straight infusion mash, mid 150's, gravity mid 1050's. The hopping is quite interesting. He was using Chinook for bittering to approx. 30 IBU, with Willamettes and Kents used for finish, with a clear but light touch. Yeast strain is Windsor. Apparent attenuation is right around 73-75%. The most dominant facet of the beer in my opinion is from the british caramel, and you will not get it using domestics. Incidentally, some local pubs will pull this beer on a handpump, which dramatically improves it's british posturing. *************** Todd queries about dispensing stout from N2 setups: The following relates toboth what I have been told by distributors and my own experience. 1) Guiness mix is 70%N2 and 30%CO2; 2) The effects of the CO2 in these types of beers are like its effect in any beer -- it adds some carbonic acid sharpness and fills mouthfeel to some extent; the CO2 coming out of solution and the high surface tension of the beer result in the famous head. The N2 basically allows the beer to be dispensed at very high pressure without effecting dissolved gas coposition. This is important for generation of nucleation sites as it is dispensed through a controlled sparkler tap (guinness tap). 3) Dispense temp is a function of temperature: I have had very good results dispensing 55F beer using 35-45 psi 4) While the flow control tap is not obligatory, as stated above, the capability to withstand very high top pressure and force the beer to initiate foaming both contibute to the foam stand. Common cobra head faucets give out and leak commonly at pressures above 30 psi. I have a Murphy's style tap which also has a flow controller valve like the older guinness types. This is a nice feature, particularly for making black 'n tans. If you are serious enough to get a separate N2 cylinder, I highly suggest getting an appropriate tap. Incidentally, I have heard that the Guinness style taps are no longer available with the flow control knob. I am not certain of theis report, but I have noticed all new Guinness taps to be of bronze colored metal, and lacking the valve. The new Murphy's taps do have the valve. When I was looking into getting mine, there was a significant difference in price, however; the valved versions ran over $110 (but I got mine free --- wheeeee!) 5) I use separate CO2 and (pure) N2 cylinders. I shoot for dissolved CO2 at about 1.5 volumes and use the straght nitrogen for dispense, usually around 40 psi. Works great for me (and not just for stouts).

Date: Fri, 19 May 1995 11:03:41 -0400 From: ggarnett at qrc.com (G. Garnett) Subject: Re: Stuck fermentations (HBD#1735) In HBD#1735, Ilkka Sysil <isysila at clinet.fi> wrote: >I cannot see very much point in cosidering cures for stuck fermentation. >Stuck fermentation definitely means that things have gone unfortunately >& *irreversibly* awry in much earlier stage of brewing process. > >Stuck fermentation is almost exclusively due to *wrong* composition >of sugars in the wort provided that aeration of wort has been done >properly and yeast & pitching rate is ok. Having a wort with too high a proportion of unfermentables is only one cause of stuck ferments (and, I should note, one cause which does _not_ apply to extract brewers!). As you note above, under-aeration and yeast underpitching can also cause stuck ferments. As can poor temperature control (allowing the fermentation to get too cold for the strain of yeast involved), use of a yeast unable to tolerate high alchohol leves in a high-gravity beer, or even a yeast that tends to flocculate early. All of these can result in "stuck" ferments, and most - if not all - of these conditions can be "fixed", one way or another. I feel that there is good reason to discuss stuck ferments on the HBD. Not only can possible "fixes" be proposed, but many readers can learn something from the discussions - and hopefully avoid making that kind of mistake themselves. On the HBD, at least, there are very few bad questions - just bad answers. Even the repeated "Help! Is my Beer Ruined?" posts. I certainly understand how these can get tiresome, but look at it from the point of view of the poster: What most of them need is some reassurance and maybe some basic tips. If the HBD's master brewers don't feel like answering, there are plenty of us who aren't that advanced who will quietly do what's needed via private email, and you can skip over the post without guilt. Recently, I've become concerned that we on the HBD haven't been presenting as friendly a face towards newcomers as we might - and in some cases, OUR treatment of these newbies will determine whether they stay in the hobby, or leave for some other endeavour. >There is no point doctoring the remaining much too high amount of dextrins >into fermentable sugars [...] In [...] brewing the ratio of fermentables vs. >unfermentables is adjusted [... during ...] *mashing* exactly the way which >comes up with desired composition of sugars in wort. That's great, and I'm sure most of the readers of the list who brew all-grain beers know about it. On the other hand, my all-grainer friends' TARDIS is broken - by the time the ferment sticks, we can't go back in time to correct the mash schedule. This is, of course, why we keep a notebook, so that we can record what we did wrong and learn from our mistakes. On the other hand, I for one am loath to pour beer down the drain (I subscribe to the Irish belief that on judgement day, you're suspended head-down in a barrel of all the alchohol you've ever spilled - and if you drown, to Hell with you). If there's a something I can do that can save the batch, I'd rather save it if it'll be drinkable at all. A "ruined" batch like that will probably never win any prizes, but when I'm thirsty I don't want a prize, I just want a beer. I sometimes wonder just how much perfectly drinkable beer is poured down drains each year by tense, worried homebrewers.

Note I run on a MAC, so you may want to scroll on down if you don't use one (you should of course go right out and buy one!). Also note that my problem related to a .z file, not a .zip file. I was attempting to download the all about grain FAQ referenced recently in HBD, I was accessing via Compuserve FTP if it matters. I downloaded it without the .z extension, presuming the server would uncompress it for me like the instructions say it will. Well, it didn't (file was full of ascii chars when i copied it to a DOS disk and tried to open it on a PC) and attempting to open the downloaded file on my MAC gave me messages that I did not have the Compress program it was created with. After a good bit of trial and failure, it turns out that this file with a .z extension is apparently a compressed unix file. I downloaded a program called MacCompress from Compuserve (apparently the MAC version of this Compress pgm), and that (finally) did the trick. For what it's worth ...

Date: Fri, 19 May 1995 10:03:20 -0600 From: flemingk at usa.net (Kirk R Fleming) Subject: dWC Malts and FG Russ Brodeur says: >I'm going to brew an English bitter... >I'm shooting for an OG around 40-45 and hope to get the FG down to 10-15 I've not used dWC--I've been using Baird exclusively for the pale ale malt, and (probably) Baird or M&F for the crystal. For light bitters w/OGs at 38 and 33 I've gotten FGs of 10 for both using 1098 and 1084, respectively. Mash was 105F for 30 min and 153-154F for 60 min. Mash pH was not measured for either run, but recent pale batches with gypsum or Burton salts have been ~5.4 at ~100F. In Fix's post (18 Aug 94) his bill of 24 lbs dWC, 2 lbs dWC CaraVienne and 1 lb dWC aromatic, run at 40/60/70C (30 min each), "typically" gets OG ~ 53. The thrust of his talk centered on the influence of a 40C rest on extraction, BUT he adds that the ratio of times spent at 60 and 70C strongly influence fermentability. To wit, if time(60C)/time(70C) = 1/3, then he said ADF will be in the low 70s (as percent). OTOH, if this same ratio is 3/1, ADF moves up to the mid-80s. He uses 15 min/45 min and 45 min/15 min as examples. Say you can get 85%, then we have: .85 = (OE - AE)/OE Using about 40 pts as the OG, to get: ~40/4 = 10P as the OE, then .85(10) - 10 = -AE, or AE = 1.5 (deg Plato) Converting to gravity: FG ~ 1.006. I don't believe it, but the only way to know is to try it, bearing in mind we don't know what kind of yeast he used to get these estimates. What I'd like is a plot based on empirical data of time(60C)/time(70C) vs. maltose/maltotriose. I think such a plot would be very interesting, especial if the Mouthfeel Index could be incorporated somehow. :-) Since Russ proposed a grain bill having about 7% non-pale ale malt vs. Fix's ~12% non-pale bill, seems he should get comparable results. Say, I have about five 1/2 gallon jugs and an excuse to brew, er, I mean a problem to research...better get cracking.

Date: Fri, 19 May 95 12:11:12 EST From: Tim_Fields_at_Relay__Tech__Vienna at relay.com Subject: Irish Moss roundup/pitching feedback Many thanks to all who responded to my query about Irish Moss. Here are the results: 7 direct responses and 1 HBD posting When to add: with 20 mins to go in the boil = 1 with 15 mins to go in the boil = 7 All but one suggested re-hydrating the IM before adding it to the boil. Length-of-rehydration-time ranged from overnight to a half an hour, with most opting for 1 or 2 hours. One to two cups of warm to very hot water was the preferred rehydration medium. Overall, respondents said that the combo of rehydration and adding 15 mins from the END of the boil produced by far the best results, but all noted that any use if IM resulted in clearer brews. Amount to use: ranged from 1 tsp. to 1 TBS. Average suggestion was 1 or 2 tsp. My favorite comment: "The smell of wet Irish Moss is like a trip to the beach" and ... RE Pitching Rates: I received a response to my response to the pitching question (say that 10 times fast) stating that pitch rates for a "standard" ale should be the slurry from a 1/10th batch size. For 5 gals, that equals the slurry from a 1/2 Gal starter (4 pts) - compared to the one pt I suggested. For higher gravities and lagers, use more (1 GAL starter or more). IMO pitching rate is important, so I'm passing this on fyi (I'm going to increase my rate). In hindsight, I may have misinterpreted the yeast FAQ - I "read" 1 PT of STARTER - it may very well have said/meant 1 PT of SLURRY - a big diff.

My guess is that your astringency comes long before your secondary, it's just that the sweetness of the unfinished wort covers it up before then. Possibly you're having tannin extraction from your grains or your bittering hop levels are high.

I paid $75 CDN for about 4 square ft. I tied it with wire (fishing line disentangles, unless you know of better knots than I. Someone want to start a "string thread"? ha ha... ) to an aluminum perforated pizza pan. All that money for stainless mesh, and no one sells stainless pans. Bitter. Whether my effective open area for runoff is limited by the open area of the pizza pan, or the mesh spacing I don't know. But I suspect that it's closer to that of the mesh A warning about the motor controller: get the pin-outs right for the triac. I wasted a day because the place I bought the thing from didn't know the correct pin-outs, and I thought I had guessed them correctly. I was wrong. As for the keg, I got a Golden Gate shaped keg without the bung hole in the side. These are ideal, because then you don't have to cut the pizza pan in half to get it into the keg. The bottom of the keg tapers in, so a 14" pan fit through the hole I cut in the top, and still rests above the bottom. I used a jig saw and blades with lots of fine teeth (31 per inch I think) to cut the keg. Cut slowly, don't force it or the blades melt. My stainless steel pipe coupling is welded to the bottom middle of the keg. Not to the side as is commly done. The bottom slopes towards the centre, so every precious drop of wort is collected. The only reason to weld to the side (as far as I can tell) would be if you have a burner heating the keg. With a RIMS, this is not an issue, so keep it simple. Though I have yet to build a stand for mine, it shouldn't be too difficult (cross my fingers). But obviously one can't simply rest the keg directly on a table top if it's got a pipe sticking out of the bottom. I'm taking next week off school, so hopefully I'll finish putting mine together. Have I mentionned that this is my favourite HBD topic...? Good luck, Eamonn eamonn at atmosp.physics.utoronto.ca p.s. I hope I spelled "Tim" correctly. Sorry again Russell!

Date: Fri, 19 May 1995 15:56:18 -0400 From: RWaterfall at aol.com Subject: Re: Starter Aeration Trick\Draft Mix Elde at aol.com said in HBD1735 - "I aerate my starter by whipping it for a minute or two at the end of the boil. (Still hot enough to hopefully kill any nasty's, and its *starter* HSA is not an issue.)" - --------- The solubility of oxygen (or any gases) in boiling wort or water is much lower than at room temp. Dr. David C. Harsh posted the following data in HBD1701: " At 20 C, solubility of oxygen in chlorine free water in contact with air is reported at 9.09 ppm. Exposure to pure oxygen would result in maximum solubility of 43.49 ppm [(9.09/.209)]. Solubility of oxygen in water at 50 C exposed to air is 5.47 ppm....at 80 C the solubility is reduced to 5.3 ppm." When you heat water up you see small bubbles being generated long before you hit boiling temp. This is the dissolved gases being driven off. - -------------- Regarding Todd Ehlers' questions about N2/CO2 gas mix (also in HBD1735), I asked the owner of a local bar [Mahar's - no affiliation,just a satisfied customer(NAJASC)] that has about 50 drafts and hundreds of bottled beers about his setup for Guinness. Jim uses straight nitrogen at 30 to 32 psi (cellar temp) for his stouts because of a side-by-side tasting he did one night using 100%N2 on one keg and 75%N2/25%CO2 on the other. He noticed a slight improvement in flavor with the N2. He said that those present who prefered the gas mix were not habitual stout drinkers. Those prefering the N2 were. He figures it's better to satisfy the diehards. He did notice that the last several pints from the N2 keg didn't do the frothing head production thing. He changes kegs when he gets to that point. Jim also said that Guinness likes bars to use the draft mix so you DON'T have the inconsistency on the last pints. He uses a 60/40? mix fror the rest of his ales (I didn't ask about the pressure) to give them a smoother feel. Technically, you need the higher pressure with draft mix or N2 because N2 is much less soluble than CO2. Also the lower percentage of CO2 (30% instead of 100%) lowers the solubility of the CO2 at a given pressure (Henry's Law). I'm not exactly sure how using 2 separate cylinders of CO2 and N2 would work. It seems like setting the pressure gauges in a 7:3 ratio (NOTE: use absolute pressure=psig+14.7psi at sea level) would give you a 7:3 mix of gas. You would need to hook up the lower pressure tank first. If you hook up the higher pressure tank first, none of the other gas will flow in. I am assuming that you would be using some kind of manifold to introduce both gases continouously and simultaneously. If you are adding one then the other sequentially, you would need to use a 10:3 pressure ratio to get a 7:3 gas mixture. The vastly different solubilities may screw this up entirely though.

Date: Fri, 19 May 95 13:29:57 -0700 From: robtrish at noif.ncp.bc.ca (Robert Lauriston/Patricia Bennett) Subject: Kirin's "first pressings" Re: Kirin's "First Pressings" Troy Howard wrote: I heard an astonishing radio ad for Kirin: "high quality first pressings" as opposed to other beers that are made by mixing the "first, second, and third pressings". I suppose that Kirin could use some sort of forced lautering process (so the wort _might_ be described as a "pressing"), but more likely the ad company has no clue how beer is made and thought it was similar to wine making. Anyone know if Kirin really uses some sort of novel "pressing" process to produce wort? I don't know what Kirin does, but I can describe some modern brewing technology. A lauter tun with a husk filter bed is the traditional method of separating liquid extract from the remains of the grain after mashing. Another method now in widespread use in large breweries is the use of a mash filter which is indeed a sort of forced lautering similar to winemaking, or similar to the filtration of beer. Coors uses mash filters and therefore there are no lautertuns in their brewhouse. Slightly embarassing when I asked where they were. As for the 'first' part of the term 'first pressings', I can speculate. (Perhaps an odd translation?) In lautering, it is common to refer to the liquid which is drawn off before sparge water is added as 'first wort'. This is the liquid which was used in mashing and the amont of it depends upon the amount of water used in mashing aka mash thickness. The analogous liquid drawn from a mash filter might be called the'first pressings'. It is unlikely that Kirin would mash with an extremely thin mash since it would be an uneconomical use of the vessels (even if they could compensate for the biochemical differences in a thin mash); therefore 'first pressings' like 'first wort' would have to be diluted before fermentation, even in high gravity brewing. I would never want to endorse beer marketing as a source of technical information about brewing, but sparging does have the potential to extract undesirable materials and so it might be justified to consider beer made only from 'first pressings' as superior. But the idea of a 'superior' beer doesn't leave much room for individual taste. The speculation really begins when you ask, what do they do with the second and third runnings? Make a different line of beers or other products? Using these liquids for subsequent mashes would likely make them too thick and interfere with mash reactions. Someone else might have a suggestion about what the difference between the second and third pressings would be. - -- rob lauriston <robtrish at noif.ncp.bc.ca> Return to table of contents
Date: Fri, 19 May 95 17:10:20 PDT From: jds at equinox.shaysnet.com (John Shearer) Subject: beer-balls greeting! A couple of quick questions for the collective: Does anyone know where I can get those rubber tops for beer balls -aka beer spheres? I have several of them left over from my younger days of drinking the 'B' word, and thought they might be a good solution to my 'beer storage' problems. What I plan to do is prime a 5 gal batch with a half cup corn sugar in solution, fill the ball, crimp the top with pliers, and wait. I would of course watch for a time to make sure there are no leaks around the top. I am used to force carbonating, but I guess I can deal with a little sediment:-) Here are the pros as I see them- They are the perfect size (5 gals). They are cheap (free plus the cost of the top - and who can afford, or has the fridge space, to have several cornies hanging around). I find the balls much easier to cool than cornies in an outdoor setting. I can store them for several months at room temp before use while they condition. No CO2 to muck with during the parties. The taps are cheap, and can be purchased anywhere you can buy beer balls. This leads to my other question - does anyone have any 'cons' or problems with all I've said? Any info would be greatly appreciated as the summer months are nearly upon us and my beer supplies are short! :-( Please respond via private e-mail because I get behind on my digests and I'm getting kind of desperate to find an economical solution. (Heaven forbid I actually bottle a batch!) I will post a summary if anything interesting comes through. TIA john jds at equinox.shaysnet.com Return to table of contents

Of course not, you blithely >chew your food and swallow it without a thought. Quit scaring >people needlessly. Sweden has recently outlawed mercury amalgams, and Germany has outlawed them on pregnant women - don't you think that means something? Whether the ADA says so or not, lots of research has shown dental amalgams to be quite toxic. Many dentists are refusing to use them, and many patients are having them removed. >Scrub the brew kettle in question with a scouring pad, wash the >residue down the drain and be done with it. Hg is a toxic and hazardous substance in our sewers, too. It's illegal to pour it down the drain in most places, so it's probably not a good practice to suggest that on the 'net. I remember a local elementary school that was evacuated by the fire department when a thermometer broke. HazMat team responded and the whole deal. Now, I realize that county agencies may over-react in order to pad next year's budget, but they must have good reason, nonetheless. Remember that textbooks are for reference, and don't always reflect real life. Numbers are fine, but don't believe everything you read.

This is not much of a gadget, but is very cheap (which really appeals to me). Take a cheap, metal pie tin, poke holes in the bottom, and suspend it over your lauter tun. That's it. You can get your sparge water into the tin however you want. Make the holes very small, at first & enlarge them if your flow rate isn't high enough. Cheers.

Date: Fri, 19 May 1995 22:00:42 -0700 From: kwhitney at ix.netcom.com (Kenneth Whitney) Subject: 10 gallon corny kegs I am interested in fermenting five-gallon batches in corny kegs and have considered the following options: 1) use a 5-gallon keg more or less as is and attach a blow-off hose to one (or two) of the fittings (with poppets removed). 2) use a 5-gallon keg without a lid as an open fermenter. 3) drill a hole in the top of a 5-gallon keg and add a 3/4" to 1" fitting for a blow-off hose. 4) use a closed 10-gallon corny keg (with air lock attached to the gas in fitting). Ideally, I would like to move the beer from the fermenter to 5-gallon serving kegs via CO2 pressure. It seems that a 10-gallon keg might be ideal. Does anyone know of a source for 10 gallon (or greater than 5 gallon) corny kegs? How about cost? What are the dimensions (is it the same height as a 5-gallon with a larger radius)? Any other (cheap) options for stainless steel fermenters? Return to table of contents
Date: 20 May 95 05:59:28 EDT From: "Robert W. Mech" <76271.3507 at compuserve.com> Subject: Hop Oil/Coconut Oil/Oil Slick I few HBD's ago, I posted a message regarding the use of pineapple, and coconut. I got a good response on the Pineapple, and alot of concern about the coconut oil affecting head retention. My response to most people's concerns was the fact that Hops too include oil, and dry hopping doesnt seem to affect head retention (or at least not significantly). So my question here is, how would coconut oil affect my head retention? Is there some special property to Hop oil that makes it not affect your head? Is "hop oil" really oil? I know that its not the same TYPE of oil, so lets not point out the obvious. If I used a "Dried" form of coconut in the boil (like a hop) would I extract too much oil? Or would it be better used in the secondary (like a hop) to extract less oil, but more flavor? Im sure ill have a hard time finding somone who has used coconut in thier beer, but maybe somone who has used another oil rich indgreedient, could lend me thier wisdom.

Date: Sat, 20 May 1995 12:20:25 +0200 From: "terence tegner" <tegbrew at iaccess.za> Subject: Copper breweries Hello from Africa again the recent discussion on copper breweries calls for comment from my side. This is purely for information and not advertising.( not that I would expect to sell from this side of the big pond.) My company makes small breweries and supplies a complete turnkey operation including brewer training so I think that we can comment with a certain amount of experience. We have installed 7 breweries around the country varying in size from 200 litres to 400 litres in brew length. All these breweries have been made entirely from copper including the wort cooler and fermentation vessels. The beer is either an ale or a lager and has a taste that brings joy to real beer drinkers. We recently had a master brewer from Berlin try our beer. His comments were to the effact that we had produce a nectar fit for the gods. there are certain things that one has to watch, however. always rinse with citric acid after cleaning with a scourer. In fact, we recomend that the cleaning is done with a high pressure water jet and then sterilise with an Iodophor. A bit of history reserch shows that in the UK there is still a brewery that uses copper fermenters as has been the case for the last 200 years over there. The MBAA has an article on fermenter construction in their book PRACTICAL BREWING which states that fermenters used to be made from all sorts of materials, including wood, and were commonly lined with copper. My advice to them who are thinking of constucting homebreweries on these line is, GO FOR IT. If its good enough for the master brewers, its got to be good enough for me.
