---------------------------------------------------------------------- Date: Tue, 20 Feb 1996 00:34:19 -0500 From: ajdel at interramp.com (A. J. deLange) Subject: Water In #1961 Ken Schwartz asked about simple water recipes using commonly available salts: For each 100 mg calcium carbonate (sometimes sold as precipitated chalk) added per litre of deionized water water you will realize 40 mg/L (ppm) calcium, 100 mg/L alkalinity as calcium carbonate and 100 mg/L total hardness as calcium carbonate. For each 43 mg gypsum added to one litre of water you will realize 10 mg/L calcium, 25 mg/L hardness and 24 mg/L sulfate. For each 16.5 mg table salt (not iodized) added to one litre of water you will realize 10 mg/L chloride and 6.5 mg/L sodium. For each 103 mg epsom salts added to 1 litre of water you will realize 10 mg/L magnesium, 41 ppm hardness and 40 mg/L sulfate. Using these amounts gives: mg/L Hardness Alkalinity Ca Na Mg SO4 Cl Chalk 100 100 100 40 Gypsum 43 25 10 24 Table Salt 16.5 6.5 10 Epsom Salt 103 41 10 40 Totals 166 100 50 6.5 10 64 10 These levels loosely approximate the waters of London, Munich and Dublin and this water should be suitable for a pretty wide variety of beers. You can adjust the proportions of the individual salts (all of which are readily available) to acheive other ion contents. For example, 50 mg/L chalk gives 50 mg/L hardness, 50 mg/L alkalinity and 20 mg/L calcium. A good way to do this is to put the table above into a spread sheet and fiddle with the left hand column as you watch the totals row. When you have numbers you like, measure out the volume of deionized water to be treated. Then add the salts. Now bubble carbon dioxide through the water via an airstone (this is emulating mother nature) and stir until all the chalk is dissolved i.e. until the water is clear. Now aerate it until the pH gets a little over 7 or just let it stand. Eventually the pH will reach 8.4 and you don't really need to check this. At this point the profile should be about what you calculated. * * * * * * * * * * * * * In the same number Ron Thomson asks about pH of mashes made with his very soft water. Very soft water has few minerals in it and so little "buffering capacity". The pH of the mash is determined by the relative strengths of the buffering systems of the malt and the water. As your water has little, the malt will predominate and in the worst case, pale pilsner malt, you should go to about pH 5.7 - 5.8. Any higher kilned malts in the grist will result in a lower number. When an acid rest is done, the calcium in the water reacts with the phytin in the malt to release hydrogen ions and reduce the pH. As your water is so soft (few calcium ions) it is unlikely that your pH will drop much during an acid rest. Also note that acid rests take a long (hours) time. Typical drops are about 0.1 pH unit i.e. to around 5.6 - 5.7. The best way to determine the amount of lactic acid required to adjust to a particular pH is to make a mini-mash i.e put a tenth of a pound of grist into a beaker with about a tenth of the amount of water you intend to use to dough in per pound. Mix well. Let the mixture sit for about 10 minutes and check the pH. Now take 1 part 88% lactic acid and 9 parts water and mix them thoroughly. Pipette a tenth of a mL of this at a time into the mini mash, stir thoroughly and check the pH. When the pH reaches the desired value, the number of mL you used to get to that pH is the number of mL of 88% lactic acid you will require PER POUND of grist in the actual mash. When adding to the actual mash, add half the amount determined in this tirtration, check the pH and then add the rest in increments, stirring and checking after addition, to make sure you do not overshoot. * * * * * * * * Again in # 1961 David Pike asks why city water at pH 8.5 comes out of his charcoal filter at pH 6.5 - 7. My usual suspicion in this case is that the filter is more than a charcoal filter i.e. a filter like a Brita filter which removes all cations and replaces them with hydrogen ions and all anions, replacing them with hydroxyl ions in which case the water will be neutral (pH 7). The other factor to consider is that de-ionized water in contact with the air will pick up carbon dioxide (as will un-deionized water but the ions mask the effect) which results in a lowering of the pH. This is simply confirmed by boiling a sample of the water and checking the pH. If it drops back to around 8.4 then CO2 was probably the cause (assuming that the filter is really an ion exchanger with a carbon cleanup filter).

Date: Mon, 19 Feb 1996 20:13:35 +0000 From: flemingkr at market1.com (Kirk Fleming) Subject: Big Open Ferment Error I brewed a 12 gal batch of a big stout (og=68) Sunday. The fermenter of choice was a 72-quart Igloo cooler, which I though would be perfect as the open fermenter. Bad call. This morning the ferment was well underway, and tonight there was serious activity. Three square feet of open fermenter really makes some noise (literally). Anyway, when I put my face down near the surface I detected warmth--wort temp read 88F--that's with a 68F room temp. I moved the unit to the garage to cool, but it's probably too late. Moral: Containers of the right shape and volume do not necessarily make good fermenters, and don't underestimate the heat produced by fermentation. Return to table of contents

Date: Tue, 20 Feb 1996 00:04:41 -0800 From: "David L. Kensiski" <dlk at campus.mci.net> Subject: Homebrew BOF at SANS '96 Attention SANS '96 attendees! I am attempting to organize (in the loosest sense of the word) a Homebrew BOF at the upcoming SANS '96 conference. If you are attending and are interested, bring a six-pack of your favorite recipe and we'll get together, taste each others' fares, and share war stories. Extract and full mash brewers alike are welcome. SANS is the System Administration, Networking and Security Conference. It takes place this year from May 12-18 in Washington, D.C. For more conference details, check out http://www.usenix.org/events/sans96.html. Check the BOF board at the conference for final details. Also, I'd like to get a rough head count, so if you are interested, please email me and let me know. And it's not too late to get that batch brewing! I just racked mine to secondary; it should be quite ready by May. - --Dave Return to table of contents
Date: Tue, 20 Feb 96 07:00:20 UT From: "Ray Cooper" <Ray_Cooper at msn.com> Subject: RE:RIMS Delivery In HBD #1963, Keith Royster asked: How do those of you with RIMS deliver the wort to the top of the grain bed gently and evenly? And do you think occasional stirring of the grain bed is necessary (maybe between temp steps) to eliminate temperature pockets, or should the grain be be shallow enough (even with a 10 gallon batch in a modified sankey keg) so as not to have these temperature pockets? I kind of followed the idea in the Zymurgy, 1992 Special Edition where the mash liquor is delivered on top of a 1/8 inch thick piece of perforated acrylic (plexiglass) which sits on top of the grain bed. I make sure that the end of the delivery hose is beneath the level of mash liquor in the tun. This tends to diffuse the flow to allow gentle distribution across the entire top of the grain bed. This works great for delivering the sparge water as well. The only problem has been that at 167F, my acrylic disk has warped. Since I mash in a 10 gallon Gott cooler, perhaps a better solution would be one of the round perforated stainless steel pizza pans that has been discussed recently on the digest. I've been meaning to check those out. This type of setup eliminates the ability to stir the mash except with possibly a concentric stirring paddle which I have considered. As long as the flow of wort liquor is sufficient to heat the grain bed thoroughly and quickly, additional stirring should not be nessesary. I've only done 5 gallon batches. I would probably incorporate a stirring paddle if I were to use a converted Sankey keg to do 10 gallon batches, especially if it was uninsulated. On the subject of RIMS systems, after hearing of the problem of carmelization of the mash liquor on the heating element of RIMS direct heat chambers and cost considerations, I decided to try something a little different. I pump the mash liquor from the bottom of the tun through 20 feet of 3/8 inch coiled copper tubing placed in 2 gallons of water in a insulated plastic bucket heated with a 1000 watt electric heating element. Kind of like an immersion chiller. I was wondering if anyone else out there had tried something like this? I know the efficiency has to be about 40 percent less (5 gal batch) than a direct heat chamber when new because 2 additional gallons are heated, but how badly is the efficiency of the direct heater affected by carmelization as it gets used?

Date: Tue, 20 Feb 1996 00:50:05 -0800 From: chemist at io.com (Brian McGovney) Subject: Yeast and sore throats Here's a question for the med students out there ... is there any reason why yeast would cause a sore throat for some people if they quaff young beer? I've made about seven batches now, all of which have been good, if not stellar, with no overt signs of contamination (no scum, no bottleneck rings after my first batch, no off flavors). In the last 3-4 batches, I've begun to notice that after primary fermentation, after I take an S.G. reading and drink the green beer from my hydrometer jug or mug, I get a scratchy throat within 12 hours. The possibility of a connection between the two has only occured to me recently, and when it did, I immediately thought of some sort of otherwise undetectable bacterial contamination as the cause. However. Yesterday I brewed a batch of Pale Ale, and whoops, I pitched the Wyeast packet before taking a hydrometer reading. Ahhh, what the hell, I'll just take a quick one now. Syphon, measure, <gulp>. It's been a day since then, and, yep, scratchy throat. But I had just pitched the yeast into wort which had been at 212F less than an hour earlier! There's no way a bacteria could take hold in the wort that fast (is there?). If it turns out that I'm allergic to yeast, I'm really going to be cheesed off. So, does anyone have an explanation? I'm sure others would like to hear the answers to this on the digest, but as I am temporarily unable to subscribe to the HBD, email replies would be appreciated as well. And thanks in advance, ya buncha hopheads. -Brian McGovney chemist at io.com Return to table of contents
Date: Tue, 20 Feb 1996 11:25:21 +0100 From: fredriks at abel.math.umu.se (Fredrik Stahl) Subject: Re: Scottish Ale Ken writes: >>Scotch ale should be pretty malty. Gabrielle writes: >>I just transfered my scottish export ale into the secondary last night >>and took the gravity reading. (OG =3D 1.050, now SG =3D 1.017) After taki= ng >>the reading, I tasted it. It tasted a bit too bitter for a scottish ale. Al Korzonas writes: >I really don't know who it was that started the fallacy that Scottish Ales >are much less bitter than English Bitters. It was probably the same person >who said that Scottish Ales don't have a hop aroma. Take a look at Roger >Protz's Real Ale Almanac (3rd Edition) and compare the BUs and aromas of >British and Scottish Ales. There is little or no correlation between hop >usage and origin.

Makes sense: it's colder up north and the yeast produce less ester= s! >You can find very malty Bitters from southern England and very bitter, >*dryhopped* Scottish Ales. This is a tricky subject since the scottish style has varied a lot historica= lly. What Al writes is certainly true for today's scottish ales (check out Caledonian 80/- for example, an extremely hoppy and refreshing ale), and what Ken and Gabrielle sais seems to apply to scottish ales of a century ago, say. Check out Greg Noonan's "Scotch and Scottish Ales" in the Classic Beer Style series for a nice historical account of the style and both present-day and 1850's recipes. The old scotch ales seems to have had much higher OG:s (up to 1.120), FG:s (around 1.030) and low hopping rates. An interesting detail is the similarity of the brewing method to lager brewing. Roasted barley seems to be an important ingredient, though it is not used in all present-day scottish ales. Greg Noonan seems to follow the AHA style definition that states OG for scottish ales between 1.030-50 and for scotch ale between 1.072-85. There is quite a big gap between the styles - comments anyone? I just transferred a wee heavy to the secondary and noted that I have failed to the high FG I wanted. The OG was lower than expected due to a disasterous sparge, around 1.059. I mashed using steps 30 mins at 40C, 20 mins at 60C and 50 mins at 70C. I expected to get an FG of around 1.020 but when racking it was 1.012 !! The wort was pitched with the dregs from a batch of Berghem Beamish fermented with WYeast #1084 Irish Ale. Even though pitching rate was very high and lag time short, I thought that the long rest at 70C would give a lot of unfermentable sugars. Not so! Next time I will try a single-step mash at around 69C. The beer was also fruitier than expected. It was fermented at 18C (measured in the beer), but apparently I should have tried to lower the temperature further. Maybe the WYeast scottish ale would be a good idea too. - ------------------------------------------------------------------- =46redrik St=E5hl Tel: int + 90 166027 Math.

Al wrote: >I've read that it is 18 inches, but this is for a commercial operation. >Then again, what's the difference between what we do and a commercial >brewery except for volume. I should have been clearer in my post. My recollection is that ideal grain bed depth is 1/2 of the smallest dimension (height or length) of the mash tun. In the case of the round gott coolers this is about six inches (the 5gal and 10gal gott have diameters of 11.5" and 13" respectively). Could someone look this up? I am sure there is a reference to this in one of the more scientific brewing resources. David; Return to table of contents

While the wort was cooling and before I pitched the yeast, a vital piece of equipment fell in the beer! Being very tired, annoyed, and panicked I shoved my unsanitized arm into the wort to retrieve the object. I know this is about the worst thing one can do. My question is: do you think my beer is definitely ruined? I have it in the primary now and it is fermenting, but will the beer have some horrid flavor? Should I dump it? Also, I use BTF (iodophor solution) to sanitize equipment. Should I allow everything to air dry without rinsing? Thanks...Kevin...liquori at acc.fau.edu Return to table of contents

It was probably the same person > who said that Scottish Ales don't have a hop aroma. All I can say is that in the time I spent touring Scotland and England last summer, I found this "fallacy" to be based in *general* fact. Sure there were exceptions but by and large the smaller "local" brews in Scotland were sweet and mild while the English beers were stronger and more bitter. One could argue that the larger "national" brands were fairly similar to each other in style; when we were able to find unique "house brands" (mostly in "real ale" pubs), I'd say it was more than a generalization. Perhaps the WATER CHEMISTRY is coming into play here...(uh oh)... Ken Return to table of contents

I've been recieving the HBD for about 1 month and have enjoyed the info. here very much. Lot'sa big brains(and heads?). I hope I'm not walking on trodden ground, but I would like the collective's opinion on two of my brewing processes. 1. I always rack to a secondary after initial activity has subsided, but I recently read in the all-grain issue of Zymurgy in an article by Dr. George Fix that many of us rack to secondary much to early (before fermentation has stoped). It separates yeast and wort at a time when yeast are in a diacetyl reduction mode. My question is this: Is a secondary really needed? Is the quality of the finished beer that much higher or just enough that only Micheal Jackson could tell the difference? 2. After boiling my wort, I put my immersion chiller in the brewpot until chilled ( about 20 min.), whirpool, then rack to primary. Question: Should I rack before I chill to remove the hot break and cold break seperately? Allmost all posting I've seen do this but not for this specific reason. Just wondering.

My SO just gave me a couple of 6 1/2 gallon glass carboys. I've been using only plastic for many years, and I was wondering about a few things... 1) Is a wine thief the only way to get samples (for SG checks, etc.) out of the carboy? Do they make one long enough for a 6 1/2 gallon carboy? 2) Has any one made weizzen with only 1 1/2 gallons of head space? Won't you need a blow-off tube? 3) Even tho I have a wort chiller, I'm asking this for a friend who also has one... Wouldn't syphoning hot wort into the carboy create HSA?

It works this way; 1) clean out a keg and fill it with an iodophor solution. Keep it until next time to keg. 2) When kegging day comes, clean out another keg and transfer the solution from the old one to the new one. 3) Rinse the old keg and fill normally. Then keep the new one filled until next time. I've sanitized 3 kegs this way with no loss of color or iodine odor from the solution. What a great way to maximize the value of your Iodophor. It also makes kegging day easy and fast.

Someone asked if there was a reason NOT to use glucose and I gave one. Other fermentable sugars work also, including glucose and sucrose, but the results might not be as good as if one had used malt extract. Growing your yeast on maltose wouldn't be much better than using another pure sugar solution lacking nutrients (particularly nitrogen). Malt EXTRACT, OTOH, contains nutrients in addition to the sugar, and generally resembles the composition of wort. Tracy Return to table of contents

I have been running my tap with a 70/30 Nitrogen/Co2 mix for quite some time (yes it is amazing) and everything works great. However, when I bottle with this mix I get a so-so carbonation with little or no head (head is good- heh heh heh). This is even after the beer has been fully carbonated and aged. I am bottling it under the same counter-pressure regime as when I bottle with just a Co2 mix and the beer is carbonated perfectly from the tap with th 70/30 mix. Has anyone on the Digest bottled with this mix? Anybody have any pointers? Private email is welcome.

I also used Wyeast's Bohemian yeast and my final gravity was 1.020. I thought I had screwed up my mashing part of the brew (my first partial mash) by having too many unfermetables due to improper mashing temperatures (boy, what an understatement), but you give me encouragement. Maybe my mashing was perfect (ROTFLWP) , and it was the yeast that caused the problem. Anyway, I went ahead and bottled. After 1 week the beer was sweet and flat. It's now been almost 4 weeks, I popped one open the other night, it's drier and lightly carbonated. It doesn't appear to be a candidate for grenades, but lager yeasts do take longer to carbonate than ales (I did a 1 week primary at 55 degrees, followed by 4 weeks lagering at ~42 degrees, fermentation had mostly finished 4 days after pitching a 500ml starter ). Well, I guess we both will just have to monitor the carbonation as the beer matures, and drink this batch right away :-)) if it starts to get too fizzy. Good luck, and let me know if any of the bottles go BOOM! Larry in L.A. Return to table of contents

Has anyone else run into >this problem with this yeast, The Wyeast Bohemian is my pet hate yeast! Here are my notes for a batch I used it in: "#2124 Bohemian Lager from Wyeast: I don't know if this strain is supposed to be this bad a fermenter. It started after bubbling in the air-lock after 12 hrs but then it took over a month (no speeding-tickets here!) to go from OG1055 to 1017 (at 12 deg C) and even that is considered a high final gravity! Day 3: Nice white head without "hills and valleys" but some randomly spread "islands" (about 1/2 cm) Day 4: As day 3 but thicker (2 cm). Day 6: A "looser" head. Bigger bubbles. Attenuation: 69% Temp.: 6-12 deg C Use: No, unless you read something else somewhere else Flocculation: OK <end of notes> I don't think I can help in any way but warn people of this strain. I used it in a Czech pils which was awful! Since I'm now not the only one that had problems with this strain I know I did nothing wrong. I'll never try it again. %%%%%%%%%%%%%%%%%%%%% WASSAIL! %%%%%%%%%%%%%%%%% % Robert Bush % % Eskilstuna,SWEDEN E-mail: bush at shbf.se % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Return to table of contents

What the = > heck is the yield you get from the mashing and sparging process. I've = > seen it expressed in points per ?=20 > Please explain. Yield is the increase in specific gravity you obtain from mashing grain. Since much of the increase is due to sugars released from the starch of the barley (or whatever), it is a measure of how well this conversion has gone and a also gauge to help you plan your next recipe. The units are the points ((SG-1)*1000) contributed by one pound of grain to one gallon of water. For example, 33 pts per pound is usually considered to be a good figure. If you mashed 10 pounds of grain in 5 gallons of water and your SG was 1.066, you got 33 pts-gallons-per pound.

How do those of you with RIMS Keith> deliver the wort to the top of the grain bed gently and evenly? I use a manifold made of copper 1/2" rigid pipe, soldered with lead-free solder. A vertical pipe goes down into a T. Each arm of the T goes out to another T and past that to yet another T. This gives 6 arms spread out from a central vertical pipe. At the end of each arm is a 45 degree elbow, soldered on so that it is lifted from the horizontal 45 degrees as well. Even feeding the single input pipe with water from the tap at 100psi, the outflow of all 6 pipes is extremely gentle. Be sure to have enough mash water in your system so that the manifold is completely submerged. For me, this is 1.1 qt./lb. grain plus a constant 2 quarts (for the heater chamber, pump and hose volumes).

One of THE major benefits of a RIMS system is that the grain bed temperature is very even due to the recirculation. First, stirring is not necessary, but more important, stirring will mess up the natural filter bed and you will lose the clarity of your wort, which is another big feature of a RIMS. Don't do it, no matter how deep your grain bed is, you should not have temperature variations. I am about to do a mash during which I will actually use a 36" BruProbe to test the grain bed evenness of heating. If there are any significant uneven temperatures noted, I will surely post a retraction of the above. dion - -- Dion Hollenbeck (619)597-7080x119 Email: hollen at vigra.com Senior Software Engineer Vigra, Inc.
