---------------------------------------------------------------------- Date: Wed, 3 Jan 1996 19:51:25 -0500 From: ajdel at interramp.com (A. J. deLange) Subject: Aeration/Crabtree/Lime/Freezing Point In #1926 Jim Hust asked if his wort might have been under aerated after a minute of sloshing: In a recent experiment I found the following levels of dissolved oxygen (relative to saturation) in 2.5 gal of water in a 5 gallon carboy (1) shaken VERY vigorously; (2) aerated with compressed air bubbled through an airstone with gentle swirling and (3) pure oxygen bubbled through an airstone with gentle swirling: Time Shaking Compressed Air Oxygen 1 minute 55% 40% 85% 2 70 62 145 3 75 75 - 4 80 82 5 82 90 6 84 92 8 87 98 D.O. level at time 0 was about 7% in all cases. Thus shaking the carboy for a short period of time is not terribly effective and the agitation must be quite violent. This is the reason the carboy was only filled half full. It would be impossible to agitate it violently enough if full. The key to getting oxygen to dissolve is tiny bubbles dispersed throughout. That is why the air stone is so effective. Note that the amount of O2 which will dissolve is a pretty strong function of temperature with saturation (100%) being about 8 mg/l at room temperature and close to 15 mg/l near freezing. Also note that it is quite possible to acheive and maintain >100% when using a carboy. If, in the course of oxygenation, the headspace becomes filled with oxygen and is then sealed off with a fermentation lock the amount of dissolved O2 will stay close to its value at the time the O2 was shut off. In the experiment which lead to the numbers above the DO level peaked at 14.2 mg/l (154% at 18.3C) and was found to be at 14.1 mg/l (158% at 20.2C) 22 hours later. If this is a concern, after aeration with pure oxygen, blow a stream of clean compressed air into the carboy after clear the O2. The DO level will then equilibrate with the O2 in the air and you will arrive at 100% fairly quickly. Note also that O2 is somewhat less soluble in concentrated worts than in water. For example, 20P wort equilibarates with the atmosphere at about 85% of the water saturation level. ********************************************* Steve Alexander and Tracy Aquilla have been discussing Crabtree effect as discussed in the literature. Here's my favorite unexplained sentence (from H, B, S &Y, Vol II p 592) : "In yeast, therefore, growth on glucose is the presence of oxygen is diauxic, i.e. fermentation procedes in the presence of glucose then the ethanol produced is respired." Can anyone explain that one? ********************************************** In #1926 Steve Alexander comments that lime can be added to water to precipitate carbonate with a resulting increase in pH. It is important to understand that while the pH may go up a bit the alkalinity, i.e. the resistance of the water to pH reduction due to malt acids, goes down. This is why it is desireable to remove carbonates. *********************************************** Also in #1926 Kirk Flemming asks if his altitude will effect the temperature of an ice bath appreciably. The answer is "no" (depending on how you define "appreciably"). At sea level (760 torr) pure water freezes at 0.0024C. At 4.6 torr ice water (and water vapor) are all in equilibrium at 0.01C (the so-called "triple point" of water). At 6000 feet the pressure is roughly (at 1" Hg/1000 feet if I remember correctly from my aviating days) 610 torr (mmHg) so the temperature should be very close to the sea level value; certainly not higher than 0.01C.

Some time ago some one asked about ways to hook up natural gas to their brew burners. I just found the flier of a company that manufactures a quick disconect for Fuel Gases. This product is specifically designed for this purpose. I saw a new house that was set up with this product for all natural gas connections including one for an OUTDOOR barbecue. The disconnect has been TESTED and CERTIFIED by both the American and Canadian Gas Associations. The flier also claims that no tools are required for a leak tight connection. For details contact: M.

Date: Wed, 3 Jan 96 22:24 EST From: cdp at chattanooga.net (C.D. Pritchard) Subject: re: Speed Boiler and RIMS heater enclosure SSLOFL at ccmail.monsanto.com (Shane) posted in #1926: >As for CO detectors, all will work but not all are practical for this use. >First alert and some others are excellent detectors, but they are not >recommended in this case because everytime they are set off, they require a >new $20.00 cartridge. This could get expensive at startup of a new idea. I >recommend the types that are resettable, so they can be used over and over >without additional costs other than batteries. There are basically 2 types of residential CO detectors. The battery powered type Shane speaks of use a CO sensitive material which changes color more or less permanetly when exposed to CO. It false trips when exposed to chronic low levels of CO. In addition, the sensor needs to be replaced every 2 years. The other type requires 120VAC power, is resettable and frequently displays the CO conectration in PPMs. UL belately revised their testing standard for these detectors on 10/95. It's *said* that newer detectors built to the revised standard won't false trip as readily. IMHO, I'd get a 120VAC type and ensure it's built to the newer standard. Standard disclaimers apply... Drop me a line if you want more details. Re: the brass sink drain tailpiece used as a RIMS heating element enclosure- I received a couple of nice responses (thanks DonBrew at aol.com and Dion Hollenbeck) cautioning about the possibility of metals from the tailpiece leaching into the brew. Don noted the that the frequency of corroded sink drains may be due to leechable metals in the brass alloy and said he used a CPVC tailpiece for an enclosure (ensure the heating element doesn't touch the plastic, do not run it dry and make sure it's CPVC and not plain PVC). Dion opts for stainless steel ($100) or the old standby, copper and wouldn't recommend either brass or CPVC. Methinks corroded drains are due to the use of drano. The tailpiece I used had no plating on its interior and was definitely brass. OTHO, brass can contain up to 3% lead (to increase machinability) and can also contain aluminum and nickel in lesser amounts. Previous posts regarding lead in brass fittings are in Digest nos. 1417, 1419, 1539 and 1544- the later two have directions on how to remove lead from the surface of brass. C.D.

Date: Thu, 4 Jan 1996 00:21:51 -0500 From: JDPils at aol.com Subject: 1056 Wyeast and 1st addition hops 1) 1056 Wyeast I want to add to the comments of M. Perkins and G. Olson. I also have found over the last three or four years mixed results with 1056 and have developed a love hate relationship with using it. It is one of the best yeasts if the goal is a dry clean tasting ale. I have had several batches which take three weeks or more to ferment and some that are completely finished and clearing in three days. I have had more stuck fermentations with this yeast than any other. The bottom line is its a great yeast that requires some TLC and control. While I cannot blame all my troubles with these batches on 1056 Wyeast, I can provide what seems to work for me. ( By the way in the end I was happy with all trubled batches). I recommend the following: 1) A one quart starter from the foil pouch for 6 gallons 2) Buy as fresh a date code as possible and do not store more than one month before starting (theoretically this should not matter but I am superstitous) 3) Aerate, aerate, aerate!! 4) Ferment at a minimum of 68 F, preferably in the low 70's. 2) 1st addition hops - This is a most intriguing to me and raises some questions. Are these hops removed before boiling or counted into the IBU's of the batch? Does the findings of the German study define how long hops must be boiled to elimintate the compounds found to be detrimental? Cheers! Jim Dunlap Return to table of contents
Date: Thu, 4 Jan 1996 18:18:57 +1100 From: merino at cynergy.com.au (Charlie Scandrett) Subject: Gorrilla proofing Maltmills There has been a bit of a thread on possibly busting Maltmills (TM) by motorising them. I posted some calculations on possible metal fatigue suggested by Jack Schmidling from hanging a motor off one by gravity. CS>When a shaft has a bending moment applied it curves in a "Radius of CS>Curvature". If a 20 lb motor was hung on a pully 1 inch out from the CS>bearing, on a 3/4" shaft its ROC would be about 450 yards, i.e. a CS>deflection of only 0.00003 inches! Steel can take this easliy. This was only partially relevant because as Jack Smidling rightly points out, JS>You also didn't bother to look at a MM and note that the shaft diameter is JS>3/8" and not 3/4". I live in Brisbane, Australia, Maltmills haven't migrated here yet. I was basing it on what I thought would be adequate. JS>Furthermore, I simply presented a possibility and not a dire warning as JS>in the case of the gear motors. The serious problem comes when one JS>puts a small pulley on the motor and the same size on the mill and JS>keeps tightening the belt till the mill doesn't slip under load. JS>It takes far more that 20lbs of tension to get this to work. I have a suggestion which would stop all such breakages. If the shaft is 3/8" and not 3/4", then it has a much lower resistance to bending. How low? It is proportional to the diameter *cubed*! (Yes, it surprised me) That is, 3/4" bends 1/16th as much as 3/8" under the same load. Also, although many variants affect metal fatigue, it has often been stated that the failure is directly proportional to the square of the flection. Thus a 3/4" shaft would have 1/256th of the metal fatigue of the existing 3/8". This window of engineering vulnerability would be closed, the machine would be "idiot proof" and even gorrilla proof!

Date: Thu, 4 Jan 1996 19:25:40 +1100 From: merino at cynergy.com.au (Charlie Scandrett) Subject: 1st Wort hopping questions George Fix in HBD #1926 posted about a new investigation of an old discarded practice of adding your prized aroma hops *before* boiling. (I checked, April 1 is a long way off!) GF>Top marks were given the the brew using 1st wort hopping, and in fact the brewery which participated in this study has now switched from whirlpool hopping to 1st wort hopping. All of this comes as a complete surprise to me, and I still have more questions about the procedure than insights. Me too, but I want to squeeze a little more info out if I can. GF>(i) While a lot of hop oil constituents are lost during wort boiling a nontrivial fraction,(which one?) at concentrations far higher than anticipated, become bound up with other wort constituents. They then underwent a series of complex and subtle reactions (mechanisms that would make those occurring in fermentation look like child's play!). This suggest that the main influence of the time of hop additions may be more on the character of the flavor induced than on its intensity. Are you saying the "1st wort" aroma was as intense as "dry hopping", but of a far more pleasing character? How about its longevity? I assume you are saying that the volatile essential oils don't survive the boil intact,( as has been popularly thought) but at the lower temperatures before boiling is reached, react with other wort constitents to form thermostable aroma compounds which are as intense, stable and more pleasing than say "dry hopping". The aroma hops will contribute their few alphas and thus IBU's, reducing some bittering hop. They will I assume also be affected by the higher hot break of infusion mashing. Questions of efficiency loom here. What sort of temperature regime extracts maximum effect? What is the consumption ratio of aroma hops by this method compared to dry hopping for the same intensity. (I assume the character to be different) Charlie (Brisbane, Australia) Return to table of contents

So I thought that I would post a message here for some advice. My kit came with a "Cream Ale" ingredient kit. The kit also came with a little booklet on how to brew your first batch but I think that first hand experiences are a more valuable tool. Does anyone have any advice or comments that they could throw my way before I start brewing. Any comments or advice would be appreciated. I just want to make sure that I don't miss or mess anything up in the process. Larry Douville Return to table of contents
Date: Thu, 04 Jan 1996 11:30:54 EST From: "Ed Lustenader" <usfmcf9t at ibmmail.com> Subject: Italian grain mill review I recently purchased a Marga Mulino made by an Italian company called Marcato. My local homebrew store only carried these and the Phil Mill, and for the value, the Marcato looked to be the better deal. This mill is kind of unique compared to the other types of mills I've seen and used. It has three rollers to grind the grain. The two primary rollers are horizontal from each other just like most standard mills. The third roller sits below and between the first two. One of the primary rollers is on a cam that can be rotated to several preset positions, adjusting the spacing to the other two rollers. In one position you can rough grind through the first set of rollers and then finish grind in the bottom set. In another position the second set of rollers are opened wider than the first so you only get a grind on the first set and the grain falls through the second. On the suggestion of one of the guys at the homebrew shop, I made a slight modification to be able to crush grain for brewing instead of grinding it into flour. By popping the cap off the knob that adjusts the roller and removing the nut and spring, I rotated the knob by 180 deg. and reassembled. This changes all the preset position and allows for a real nice crush. The cost of this mill was only $45.99, which I didn't think was too bad considering most of the other mills are closer to the $100 range. After grinding 10lbs of grain through by hand, I decided to motorize it. So over the Christmas holiday, I rigged it up to an old fan motor and gearbox. It seems to work pretty well although I haven't ground more than a couple of pounds of grain with the motor attached. The homebrew shop that I picked this mill up at is called the Merchant of Vino and is located in Ann Arbor off Plymouth Rd. There phone number is 313/769-0900. They could give you more information about the distributor. I am in no way connected with either of these companies, just a satisfied customer. Hope this review is helpful to anyone contemplating the purchase of a new mill. Regards, Ed Lustenader Return to table of contents
Date: Thu, 4 Jan 1996 09:51:24 -0800 (PST) From: louisp at gladstone.uoregon.edu (ummmmm.......Fred) Subject: Wort coolers I am _almost_ ready to brew my first batch of beer. I can hardly wait! I try to read a bit on a subject before jumping right in. I have heard that wort coolers are important. I saw one at a local brew supply house, and said to myself, "heck I could build one of those." I went to a local home improvement store and bought a twenty foot length of copper tubing, and a few fittings. To get to the point, how can one bend the tubing without kinking it? I never thought of that till I was reading "The Complete JOY of Home Brewing." I read that it could be a pain, and that I should leave it up to my local plumber. I am, however, a stubborn person who likes to do things like this myself, if possible. Any suggestions??? I really would like to keep from ruining any of the tubing. Also, I was wondering, doesn't the wort pick up any metallic taste? And, is the tubing sterilized upon immersion into the boiling wort (makes sense it should, but...) Thanks :] Return to table of contents
Date: Thu, 4 Jan 1996 13:57:19 -0500 From: KennyEddy at aol.com Subject: Random Thoughts about Distilled Yeast Interesting article by A. J. deLange about storing yeast in sterile distilled water at room temp. Being a slant-impaired individual, I began thinking about how one would do this with a smack-pack instead of a slant, and had some random thoughts. Tossed out for cannon-fodder: 1) Is there anything inherent in the slurry in a smack-pack that would render it unusable in this way? (I assume they are packaged in a sterile manner or thereabouts, so my guess is "no"). 2) If answer to (1) *is* "no", then I presume one could either divvy up the slurry directly from one smack-pack (requiring perhaps multiple starter stages later ofr the small amount of slurry), or make a starter and divvy that up (greater volume but perhaps more risk of infection?). 3) Could we just package up unsmacked smack-pack slurry (divided into small portions) or slurry from swirled spent starter (sterily, sterily, sterily, sterily), and store at room temp or at least refrigerated, and expect this long-term (year or more) storage capability? I know one can store a starter in the fridge for several weeks; perhaps the cited study gives us confidence to split a starter in this manner and store it even longer, perhaps even at room temp (more spouse-friendly). Would the alcohol, pH, and minimal residual sugar left in the the starter be enough to inhibit bacterial growth? Comments from the yeast gurus?

Date: Thu, 4 Jan 1996 13:27:18 -0600 From: SSLOFL at ccmail.monsanto.com Subject: More on WYeast 1028 (London) Here is my recent experience with WYeast 1028: I brewed a brown ale using malt extract in order to introduce a beginning brew-partner to our (the HBD Collective's) hobby. I prepared my starter several days before at room temperature (70-72 F), and everything appeared fine. I fermented the batch in my basement which was 63-65 F - on the cool side for an ale since I wanted it to be smooth tasting. I thought this would be warm enough to ferment to completion, the generic temperature range for ale yeasts is 60-75 F. A few days after the fermentation ceased, I was disappointed to find that the s.g. read 6 to 8 points higher that the recipe told me that it should have been. I racked to the secondary in order to aerate the yeast (and hopefully kick-start the little suckers!), and moved the secondary to a 65-68 F location. No change occured in the s.g. after a week or so in the secondary. I primed with 3/4 cup of corn sugar and bottled. After sitting for two weeks at 65-68 F and two more weeks at 70 F (I moved the bottles upstairs), there is little sediment and they are somewhat undercarbonated - even for a brown ale. Here are Greg Kings theories on the yeasty taste in his beer after using WYeast #1028: (HBD #1927) > 1) Fermentation temperature (70-75 F) was too high? > 2) The yeast flavor could be less noticeable in a bigger beer? > (This batch OG = 1.047, FG = 1.007) > 3) Bad combination of fermentables? > (5.5# malt extract, 1# honey, 1/4 cup molassis) > 4) WYeast 1028 always produces yeasty tasting ales? Here are my responses to Greg's Thoeries: 1) Possibly. My fermentation temp. was 63-65 F in the primary, which must have been low. According to our results (Greg's and mine), I would guess that we should have tried temperatures of 68-72 F. Has anyone else had good results in this range with 1028? 2) I'll leave this one to the collective. 3) Your fermentables sound good to me. I used 6.6# malt extract with no adjuncts - I wish I had added honey! 4) My brown ale tastes good, smooth - as I wanted it to be, but not yeasty. Of course, I had problems with too little viable yeast. Instead of being able to answer all of your questions, Greg, I added to them! Oh knowledgeable collective of HBD readers, please help Greg and I. Shane Lofland (sslofl at ccmail.monsanto.com) P.S. Sorry I didn't include many specifics such as gravities and brands of malt used. I am at work, but I can get the info. from home if anyone needs to know what they are in order to respond. Thanks in advance, everyone! Return to table of contents

After two unsatisfactory attempts at producing a fruit wheat beer I decided to at last ask for help. My problem has been that the bottled beer will not clear. The fruit (raspberries or boysenberries) are steeped prior to the boil in water before the malt extract is added. After hearing about pectin causing cloudy beer I have been careful to remove the berries before boiling. Berry juice is also added to the secondary at after racking. Gelatin added to the secondary improves the clarity but nowhere near as good as a wheat beer with no fruit. Can anybody suggest a cause / solution to this. ? Is pectin extracted from the fruit well below the boiling point of water ? Am I expecting too much from a fruit wheat in terms of clarity ?

Date: Thu, 4 Jan 1996 17:07:20 -0500 From: Simonzip at aol.com Subject: Starters / HSA As I understand it, when making yeast starters its a good idea for the stater to be roughly the same gravity as that the beer will be. That being the case, are there any formulas to accuratly determin the gravity of a starter without dropping a hydrometer into it? I currently put 5-6 tablespoons of dry malt extract into an Erlenmeyer flask with 400-500ml water, boil, cool, pitch, shake. Hot side aeration, I'm quite foggy about this. I do extract & specialty grain beers. I boil in a 3 gal. pot and end up with closer to 2 gal. at the end. I put 3 or 4 gal. of cold water in my 6 gal. fermenter and pour the wort through a strainer in my funnel, into the fermenter. I've been sitting my pot quietly in the sink with ice water to cool. I have NOT been tracking the temp of the wort at the time I pour into the fermenter. Anyway, my question is: if my wort is still very hot (say 130 deg.) when I pour it into the fermenter, will I get HSA? With my techinque, what should I do to avoid HSA? One other thing, should i be concerned about indirect low wattage incandecent light in my "winter-fermenting-closet" (3'x3'x6' closet with 40W light bulb with steel shade facing the floor) ? I remember reading some discussion about this.... Thanks in adavance Darrin Return to table of contents

My SO and I are just about to do a minor kitchen remodel and the question arose as to what type of faucet I would like to help make the old brewing and subsequent cleanup (Ick!) easier. A quick trip to the local hardware/plumbing store only served to confuse the issue even more and so now I find I must bow down and ask the collective for their suggestions and wisdom. Since I suspect that most of you, like me, have been stuck using whatever faucet was at hand maybe I won't get much wisdom...however, it never hurts to ask! Private e-mail is fine and I will post a consensus. Thanks much! Kevin Return to table of contents

They said it's the same thing, so it's totally interchangeable. I hope they're right. Robert Bush Ps.

Date: Thu, 4 Jan 1996 18:09:39 -0500 From: KennyEddy at aol.com Subject: Rev 2 of the Floating Keg Pickup Thingy Refer to my earlier "floating cork" suggestion which was in response to a request for a floating pickup to prevent settled gunk form being sucked up. I have since thought of a slightly simpler approach which would probably work better. The idea of the tubing exiting from the bottom of the cork in the previous design was to help stabilize the cork in the "upright" orientation. This can be accomplished with the tubing exiting the TOP of the float by using a "wider cork". Cut a disk of Styrofoam the diameter of the inside of the keg, then trim two sides of the disk to the width of the hatch (so you can cram it into the keg and remove it easily). Poke a hole the size of the ultra-flexible surgical tubing through the center of the disk and feed the tubing through it just enough to hold it in place (undersize the hole so the tubing force-fits). Use enough tubing to reach from the shortened dip tube to the bottom of the keg with ample slack. The idea is that the tubing will loosely coil on top of the float when the keg is full, and uncoil as beer is dispensed. The flexibility of the tubing and the slack of the coils should prevent the tubing from kinking. Poking the hole at an angle might ease any tendency for the tubing to kink at the float. The tubing enters the float from the TOP so that beer enters from the BOTTOM. I'm guessing but a 1" thick piece ought to float without needing a weight to keep it from tipping, even with excess hose coil sitting on one edge of it (as would be the case when the keg was full). Question: would Styrofoam taint the flavor of the beer? Perhaps a different float material would be best. Maybe cork or a plastic box?

Generally I have been able to stretch one cartridge to last until the mini-keg is nearly empty. For me that means about a week :-) Now I am losing considerable CO2 from seal at the face of the CO2 cartridge and the cartridge empties over the course of a few hours. The "gasket" (HDPE?) seems to have taken on a permanent deformation from the cartridge. I've tried to insert an o-ring between the cartridge and the dispenser seal, but this hasn't worked well as: 1. the o-ring prevents the penetration of the needle into the cartridge. 2. I can't effectively align the o-ring to the cartridge, so a good seal is difficult to achieve. Is anyone aware a a simple fix here. The sealing surface on the dispenser does not seem to be replaceable. I've considered injecting some silicone sealant into the assembly just prior to installing a new cartridge, but that seems so brutish. Is my dispenser ruined.

I have been using a chest freezer for several years now to serve and lager been with. It works great, but I miss the ability that I had with a refrigerator to mount taps on the door. Since the sidewalls of the chest freezer is where the cooling cools are, I don't dare drill through it. I don't like cutting holes in the top of the freezer unless there is no other way.

One thing about that yeast, it is _highly floculent_. I mean, I drank a beer and went to the bathroom and when I came back I had to roust the yeast!!! It finishes with a mild sweet flavor, so if you have a lot of unfermentables to begin with it does have a tendancy to be on the 'sweet side.' You didn't mention what volume you boiled so areation may be a concern, but yeast volume is always nice. Always make a starter! Write this down... Always make a starter......

It's just as well - many of us >found it problem-prone, although some are happy with it. This must be a reference to my recent post. I didn't buy an Airstat, it's a Set'n Save I. I'm curious whether it has the same electronics or not but in case it fails, I've got a pretty good idea what to check. Anyway, the Honeywell sounds like a nice option for someone setting up a beer refrigerator. It was a lot of fun building the electrical gadgetry for the Hunter, though, and I learned something in the process. If anyone wants details, send me an e-mail. By the way, check out the current Radio Shack catalog. There is a "new" panel-mount LCD clock/thermometer module that supposedly can be used as a thermostat with additional circuitry. Standard disclaimer. On another subject, not to long ago, someone was experimenting with a concrete grain mill. How's it working? I've been considering making one myself. I've also been keeping my eye out for a source of inexpensive grinding wheels with the idea of laminating them together with epoxy to form the grinding rollers. Has anyone tried anything similar?
