---------------------------------------------------------------------- Date: Sun, 18 Mar 2001 13:24:47 -0500 From: "Tom Williams" <williams2353 at hotmail.com> Subject: Chiller Wars - Thermodynamics skirmish Ron LaBorde and Ken Johnson raise questions about heat transfer: >From: Ken & Bennett Johnson <fearless1 at abac.com> > >.... A lot of water, moving slowly past the inner (hot wort filled) >tube, >will perform the best. It will also use the least amount of >chill water!..... "He said the air moves through so fast, that it cannot absorb the heat = as well." OK, the answer to the velocity question depends on the objective. If you want to maximize the rate of heat transfer between the fluids, then high velocity is good. The heat transfer coefficient increases with higher velocities (Reynolds number). However, if it is efficient use of the cooling medium (i.e., optimum cooling water pumping power or air conditioner condenser fan power in your A/C example) then there is some optimum flowrate which balances increasing fluid film coefficient with cooling medium mass flow. For cooling wort, I don't believe the cost of the cooling medium flow is an issue. Pump as much through your cooler as you can, and I challenge you to detect the incremental cost of the higher flow.

Date: Sun, 18 Mar 2001 11:12:16 -0800 From: "Steve Guernsey" <flight8341 at home.com> Subject: Braided PVC tubing We at Garage Brewing finally got to the point in our brewery expansion that we were able to run water from HLT to ferment. We decided on the green light for the 50 gallon brew session next Saturday. However, we noticed an off flavour in the water of the garden hose variety. In assembling the new brewery we opted for the braided PVC tubing that can be found at the Home Depot, which is responsible for that off flavour. It was sturdy enough to hold up on the input of our pumps (doesn't "squish"). We assumed that since the tubing was intended for residential water applications that the odor/flavour would simply rinse out. This has not been the case yet. We currently have the tubing soaking in water. Has anyone else used this type of tubing? How do you get rid of that PVC flavour? If we can't, could anyone recommend a suitable alternative? It has to be semi-rigid however. We would prefer to not go to a rigid pipe set up like copper. Also, in a similar vein, is the vinyl tubing they sell at Home Depot, the same as that sold in your typical brew shop? Thank Maltose above for the HBD! Steve G.

I have been told by a refrigeration mechanic that if the fan motor in the condenser unit is replaced by a higher speed motor, that the air moves through the coils too fast and less not more cooling efficiency will occur Note the word efficiency. A race car isn't very efficient but it does run fast. It just means that you will get increased cooling but at a higher cost due to the higher powered motor... I don't think it will hurt anything.. - -- Rod Prather, PooterDuude Indianapolis, Indiana Return to table of contents

Date: Sun, 18 Mar 2001 19:18:01 -0600 From: Rob <shrav at swbell.net> Subject: cold break question Hey all. .got another question.. I was in the bookstore reading brew ware's equipment book (cool book, btw), and was reading on reasons for dropping wort below 60 to get a good cold break to drop out haze forming proteins.. for a clearer final product.. This sounds like something i'd be interested in doing because my first batch (a wheat) i made last month was quite cloudy.. My question is, if you do drop the wort temp below 60, how long should you keep it down there, and also do you let it warm back up before you pitch the yeast, or do you pitch the yeast, cover it up, and let it rise to normal fermentation temperatures? I'd imagine the latter to prevent contamination that could occur while waiting for the wort temp to raise to normal temps.. Thanks rob apls at altavista.com Return to table of contents
Date: Mon, 19 Mar 2001 02:00:00 -0500 From: "Jason Henning" <jason at thehennings.com> Subject: GFI Clarifications Hello- There sure seems to be some misunderstanding about GFIs. GFIs simply checks to make sure that the current on the neutral is no more than 10 milliamps less than the current on the hot wire. If it is, it trips. Everyone seems to under stand that part. Here's were the confusion lies. GFIs are susceptible to tripping with inductive loads. Inductive loads have windings, examples are motors, transformers, and ballast. Induction causes the current to shift out of phase, this shift is called the phase angle. The cosine of the phase angle equals the power factor. In these situations, amps x voltage does not equal wattage (as in a purely resistive load), instead, amps x voltage x power factor equals wattage. Btw, loads with phase angles cheat the power company because your meter reads wattage. When the amperage and phase angle are great enough, the GFI thinks the hot and the neutral are imbalanced and will trip. Yes, it will trip although there is no true ground fault. For this very reason the National Electric Code exempts deep freezers, refrigerators, sump pumps, ect from GFI requirements. While leakage (a small current direct short) will cause a true ground fault, the phase angle can appear to a GFI to be a ground fault. OK, so what happened with Bob Sutton's fridge then? I'm guessing it's an older fridge. It probably has developed some leakage and the leakage has continued to worsen with time. Perhaps when the power was restored, there was a spike that compounded the leakage or maybe it was just coincidence. Anyway, the leakage and the current/phase angle situation combined makes for what appears to be a 10 milliamp fault to the GFI. If the fridge is plugged into a GFI, the simple solution is to replace the outlet with a standard outlet. You could even get fancy and get a single receptacle outlet. If it's a outlet that's fed by a GFI, other action needs to be taken. A picture is worth a 1000 words, so see my diagram at http://thehennings.com/images/brc/gfi.jpg . This method allows you to change everything without needing to pull any new wire or opening up the walls. All changes are made in the junction boxes. Here are some comments that need correcting: "If the GFCI doesn't trip when a substantial load is applied (try a blow dryer), it is probably ok." - GFIs don't provide overcurrent protection, you can run 30 amps through a 15 amp GFI and it won't trip because of the current. It may fail because it's not designed for 30 amps however. "The leakage that is causing the GFCI to trip is probably not enough to trip a circuit breaker." - Circuit breakers do not provide ground fault protection. Only when the hot wire is drawing in excess of the breaker rating will it trip. "The fridge might work just fine on a non-GFI circuit but remember that the GFI is telling you that there is an inappropriate path." - Not necessarily, the fridge's current and phase angle may be the only problem. "[A] GFI outlet provides a redundant safety mechanism to a properly grounded electrical circuit." - A normal circuit has no GFI protection. A GFI provides additional protection, not redundant protection. "In the case of a direct short between the phase and the ground wire within an appliance there will be a 100% imbalance between the phase and the neutral i.e. all return current will flow through the ground wire and none through the neutral. That is exactly what the ground wire is there for so the GFI does not sense a "ground fault" because there isn't one." - False, the definition of a ground fault is current flowing to ground whether it be thru the ground wire or some other path. For example, a $15 outlet checker with a GFI test button puts a small load (15 milliamp I believe) between the hot and ground when the button is pressed causing the GFI trip. And so concludes the lesson... Cheers, Jason Henning http://thehennings.com/ Sometimes we brew in no particular way but our own. Return to table of contents

Date: Mon, 19 Mar 2001 01:00:45 -0800 From: "Hedglin, Nils A" <nils.a.hedglin at intel.com> Subject: More wide ranging questions Hello again, time for more questions: 1) I'll be bottling the Honey Porter I made this coming weekend. Somewhere I read that you can use a mixture of ammonia & water to remove the labels off beer bottles. But, now I can't find the reference. Anyone know what dillution mixture would be used? 2) I'll be brewing the Honey Porter again, but using the recipe's suggetion of Wyeast Irish Ale instead, but this will be the 1st time I'll be using wet yeast. Effectively, what's the difference between Wyeast & Whitelabs & which would you recommend? I thought the main difference was that the Whitelab was immediately pitchable, & Wyeast needed to have a starter made. But, the guy at the brewing store said that the Wyeast was immediately pitchable too. 3) I'm also planning on dry hopping, but the original recipe doesn't call for it. What amount of which hops (bittering or aroma) should be added? I only have access to pelletized hops if that makes a difference. 4) Any way to reduce the undesirable flatulent affects of beer? 5) A local Caribbean restaurant introduced me to my new favorite drink called a Raddler. It might be a play on the Snakebite, since it's made with 1/2 Newcastle & 1/2 non-alcoholic Ginger Beer. It's a very refreshing drink, the ginger beer cuts the alcohol & the alcohol cuts the ginger taste. It's kind of like a dark Zima. Any ideas on the history of this drink? Is it really from the Caribbean? 6) Is there a problem with pitching too much yeast in the wort? I would like to try splitting a batch after the boil & use 2 different types of yeast to see how they affect the beer. Should I reduce the yeast for these 2.5 gallon batches? Thanks again, Nils Return to table of contents
Date: Mon, 19 Mar 2001 07:19:59 -0500 From: Jeremy Bergsman <jeremy at bergsman.org> Subject: Is this a new style? Sean Richens proposes a malty, cascade-hopped near lager and wonders if it is new. It sounds a lot like what a lot of brewpubs turn out as a pale ale. Yours would be darker, maltier, and hoppier, but basically similar. It seems to me that many lesser brewpubs ferment their ales very cool to court the "clean and crisp" beer crowd. It also reminds me of a strange house brew available in a bar in Palo Alto, CA. In addition to their house brew they have SNPA and some slightly colored megabrew. I'll be damned if their house brew doesn't taste like a blend of the two. In any case Jeff doesn't claim to have invented the style, so if you name it and promote its brewing, you will have the same claim to fame as Jeff. Well, OK, I guess you'll still never the be the center of the homebrewing universe. - -- Jeremy Bergsman ------------------ \ | Look! | / \ | New contact info | / _\/ ------------------ \/_ jeremy at bergsman.org http://www.bergsman.org/jeremy _ _ /\ /\ / \ / \ Return to table of contents

During the yeast session, one of the >speakers had a bullet point on his overhead stating that 4 - 6 hours post >pitching is the ideal time to add oxygen. > >Has anyone else heard this? I'd be interested in the explanation they supplied, Ant. I wrote about the issues regarding O2 addition not so long ago in the digest. According to some studies, the first thing yeast do when they land in a bucket of fresh wort is 1/ ignore the wort sugars !!! 2/ start using their internal carbo reserves to make sterols from squalene reserves. I hesitate, especially on a HB scale where the yeast condition at pitching is so variable from making specific O2 addition recommendations. *IF* the yeast you pitch are fat and sassy, then if you pitch the recommended levels in a conventional (10P-15P) wort they will have enough carbos stored to develop saturation level CO2 and *begin* bubbling before using any wort sugar. They'll use only a small amount of O2 for the squalene->sterol production at that time. If the yeast are carbo depleted or (use an iodine test) they will need to use wort sugars earlier and only slowly develop the trehalose they need to produce sterols. and you *may* get a delay. In any case it's extremely likely that by the time you see 1st bubbles, whether that's 5 hours or 18 hours, your yeast will need O2 to develop any further sterols and UFAs. Also that earlier O2 *may* not do much good, especially if they yeast are in less than ideal shape. I suspect that part of the reason why later O2 addition is recommended is that commercially re-pitched yeast is not in ideal shape, they may have less than idea carbo and squalene levels. That is part of the trade-off between making great beer and making great yeast and not a condemnation of their methods. -S Return to table of contents

I've been using my 48qt rectangle Coleman coolers (mash and liquor tank) for almost 2 years now with no ill effects - and I paid about $28 for the both! John C. Stegenga, Jr., Woodstock, GA. <<< John and others, As with any brewing device (CCFs included), what's important is your own satisfaction. I plan on going all-grain this spring, and I have decided to shell out the extra money for a beverage cooler. Let me tell you why :)... I am a fairly novice brewer, still stretching my hobbying muscles. Currently, I brew 5 gallon batches of a wide variety of styles, low and high gravity. However, I anticipate moving up to 10 gallon batches of some beers in the near future. Ideally, then, I would like a mash/lauter tun that allows me to mash anything from a 5 gallon low-gravity beer to a 10 gallon mid-gravity beer. Correct me if I'm wrong, but it seems to me that the most important factors when choosing a cooler are 1) ease of conversion for beer use and 2) depth of the grain bed. Since most coolers are equivalent in regards to ease of conversion, I have focused on the depth of the grain bed. In order for me to get a reasonable grain bed (minimum 4 inches) on a low-gravity 5 gallon batch, I would have to use a 5 gallon cooler, which makes mashing grains for a 10 gallon batch pretty tricky. However, the beverage coolers have a much smaller footprint, which allows me to have a decent grain bed in a much larger cooler. The 10 gallon Gott or Igloo coolers are sized such that I can mash the grains for any 5 gallon and most 10 gallon beers while staying within a reasonable grain bed depth (4-12 inches). Yes, the beverage coolers are substantially more expensive than the rectangular coolers. However, I believe that the added versatility is worth far more than the $20 it will cost me.

I made the mistake of projecting my experience which is mostly with 3-phase GFI's to single phase. Now where I violently disagree with Forrest is as to whether discussion of such things belongs here. It unquestionably does. If it's found in a brewery or homebrewing situation it can and should be discussed here. We discuss all maner or arcane intricacies of yeast metabolism, the physical chemistry of pH measurement, the relationship of fermenter aspect ratio and so on and on. I learned something from this particular discussion and hope others did too. Those who disagree with this viewpoint have the option of using their pagedown key.

I assume using CO2 at 10 psi since that is about the pressure that I normally have available in my manifold unless I disconnect all the other kegs first. Also assumed in no solubility of oxygen in beer. 1 purge takes you to 75% of original oxygen level. 2 purges takes you to 50% of original O2. 3 takes you to 25% ...... 5 takes you to 10% ........ 6 takes you to 4% ....... 9 takes you to 1% ....... 14 takes you to 0.1% ...... If you use higher pressures of CO2, it helps to decrease the # purges - for example using 20 psi CO2 will require 3 purges to get to 10% of original concentration. I turned up this info in a recent trade publication for ChemEng if you want to see the easy equations. Chem. Eng. Prog. Feb. 2001. page 57 to 61. author is G. Kinsley. title is "Properly Purge and Inert Storage Vessels". Thought you all might be interested. My normal purge is about 4.

I've noticed a slight change in my beers in the past year that I have filtered the water instead of boiling it. Chloride: 20.8ppm Nitrate: 2ppm Nitrite: <.3ppm Sulfate: 40ppm Calcium: 38.5ppm Copper: 18.4ppm Iron: <10ppm Magnesium: 9.1ppm Potassium: 3.1ppm Sodium: 19.5ppm (but this is only based on a month of 12ppm and one of 27ppm. Surface water is avg of 30ppm) pH: 8.2 Alkalinity: 76.4ppm Chlorine: 2.6ppm Total Hardness: 135.4ppm Now, as I see it, the chloride is low, the calcium is low, the sodium could be low, but I don't have enough real info, but the pH is pretty good. I figure that for most of my beers, the grains in the mash will take care of the pH. This has been confirmed by pH measurements. It is always between 5.3 and 5.8, but does change with the season. I filter the water as it stands right now because it removes the chlorine (we just switched to chloramine). I wonder how much stuff that I am low on already is further filtered out in the process. Any comments on what to do with this water? I usually brew British styles, and it does not look very good for that at all. Thanks in advance for your help. Return to table of contents

Definitely not an award winner, but it made it drinkable. I have had better success with their dry mead strain. As far as local v. mail order, I try to mix it up. Both are important to the craft in their own way. How to lager large batches? Well, I also have a dorm fridge (currently for yeast and hops) and a regular fridge for lagering. This is great for a single batch, but when I reuse the yeast, the problem becomes how do I maintain both primary and lagering temps for the two batches now that spring is here? I think I see a fridge-powered room in my future. Speaking of fridges (all hail FridgeGuy), I got a glass display fridge from the local rec center. They were getting a little tired of having to have the old unit recharged every month, but it ran fine so I took it off their hands. Can I leak test this unit? I have access to an auto shop that repairs car air-conditioners, is the equipment and refrigerant the same? Do I need to get the make and model of the fridge to answer this question?

I will call it "Winnipeg Lager" > The blurb goes: "a moderate gravity lager, with lots of Cascade hop > character, and a combination of German and English style maltiness". > Numerically, I'm aiming at 10 SRM, 31 IBU. My target gravity > is 1038, but > the "commercial" version would be the usual 5% ABV. First off, Sean, it sounds as if your style is a slightly cleaned up version of that overhopped abomination that is Left Coast pale ale. As if Winnipeg doesn't have enough nasty things associated with it (mosquitoes, 9 months of winter), now you would tie in our city's good name with Cascade hops? Get thee hence to the pit of eternal damnation (aka River City brewpub) for such a suggestion. If there is beer in hell, it will surely be hopped with Cascades. Now, your goal is a laudible one, but for a true Winnipeg lager, why not search out the wild hops that grow in our province. I'm told there are some along the riverbank behind our place. The native Manitoba hop has a proud history of commercial usage here, and I think it behooves us to resurrect that tradition if we hope to think of this as a truly local beer. Dominion Malting malts, native hops, and water straight out of the Red, as muddy as you can get it. Now that's a Winnipeg Lager! I'll leave the smoked goldeye addition to the secondary as an option for the truly adventurous. Cheers, Brian Return to table of contents

I also make sure that some of the liquid fermented beer gets in the container with the yeast. I fill the container with about three quarters yeast and one quarter liquid. Then tighten the container so it is air tight, otherwise it will leak. A good container size usually stores about 6 teaspoons of yeast, which is enough to start another five gallon batch. I've kept six different yeast samples of ale and lager in the refrigerator at least one year with excellent results. I've made several five gallon batches of beer from the original yeast sample with the yeast stored around two to three months between pitching. As I said, the longest period between pitching the stored yeast was approximately one year. Just take a sample out of the refrigerator and pitch it in your wort. I don't worry too much about sanitation. I wash a container but do not disinfect it with anything. I figure there is enough alcohol in the sludge and beer to keep it clean for future use. It seems to have worked to date. Cheers Stearns Return to table of contents

Q: Did you do a starch test on just the Laaglander DME, without crushed grain present? I suspect you may find no starch. If this is the case, then the Laaglanders high FG is due to dextrins, not starches. Q: What was your mash temperature? I suspect you tended to the lower end of the temp range (152F? Lower?) I don't used Laaglander myself, (I used Munton&Fison in my extract days) but know of several people who do, that will benefit from your experiment. Thanks for sharing your results!

Date: Mon, 19 Mar 2001 17:32:28 -0600 From: "Paddock Wood Brewing Supplies" <orders at paddockwood.com> Subject: mail order vs. local and shipping costs Mike in New Orleans says, with regard to mail order vs. local:" You could probably beat the shipping costs on a 50 lb. bag of malt even if you had to drive 2 or 3 hours each way to get to a retail operation." I have to disagree. 2-3 hours each way in my little '87 Honda Accord is about 1.5 tankfuls of gas at about $35 per fill. (Excuse my rough calculations, I know some would prefer that I adjust for headwinds, asphalt conditions, the rubber wear on the tires increasing the revolutions required on the return trip...but I save my retentiveness for beer making.) I can ship a 25kg sack of malt from Saskatoon SK, (just above North Dakota, eh) to Halifax on the East Coast for a shipping cost of about $28. Unfortunately it's not much less if I want to ship it to Regina, which is within the 2-3 hour proposed range. But add in the 6 hour drive and the gas, and it makes more sense to ship. Even if you are only 2-3 hours away. If you ship 4 sacks of malt, then it may be worth a 6 hour drive. And of course with shipping you don't get to hang out in the brewshop and talk beer. A brewshop is perhaps the only store more fun than a hardware store! Bill asks about the differences between local and mail order shops. I can hardly claim an unbiased opinion here, but I agree with the general sentiment: support your local shops! Provided, of course, that they support you: many in the US are fortunate to have brew shops that stock all-grain supplies. Not so here in Canada. Most suppliers stock tins, a few extracts, a few have a small selection of stale specialty malt, and a few sad stale hops. So I have a caveat: ask your local shops for the supplies you need. If they cannot or will not carry them, then support a good mail-order shop. Apologies to HBDers who have heard it all before, but I must rant! <condensed rant> Paddock Wood started because there were no local shops catering to serious all-grainers. We have discovered that similar situations exist all across Canada. If it weren't so, we would be out of business. We have no desire to compete with other cities' local shops. Homebrewers saving a few bucks ordering mail-order can doom their local shop. But until such time as local shops in Canada carry more than kits, Paddock Wood will have a growing mail-order business. I get immense satisfaction at enabling someone in Vancouver or Halifax to brew great beer, and even more satisfaction at bringing the same great ingredients to far flung towns and remote villages like Iqaluit, Baffin Island, NWT, or Toronto. I wish good supplies were to be had everywhere, but until that time, pick a shop, local or mail-order and work with them to get what you need. You will gain the biggest impact in what is available by concentrating your brewing dollars. Brewers that shop widely for the best deals are not always making the best decisions for the hobby. If your local shop stocks a malt that you can get cheaper by $5 a sack by mail, BUY LOCAL. You'll spend a lot more than $5 if your local goes under and you need some brewing item. On the other hand if your local doesn't stock something that you deem essential, and will not stock it, move your brewing dollars until they do. If you simply mail-order in the one item, there is no inducement for the shop to change, and no inducement for the mail order outfit to continue a wide range of products either. Move all your business to the shop that offers the best service, local or not. (A shop does not live on Peat Smoked Malt alone...). </condensed rant> cheers, Stephen Ross -- "Vitae sine cerevisiae sugant."

Date: Mon, 19 Mar 2001 17:49:13 -0600 From: Chuck Dougherty <jdougherty at wlj.com> Subject: convoluted tubing counterflow chillers All of this talk about counterflow chillers over the past few weeks has finally inspired me to upgrade from my immersion chiller. I am interested in hearing what anyone has to stay about the convoluted tubing chillers, and wonder if anyone has any hard data comparing them to regular tubing chillers. Are there any issues other than efficiency/length I should consider with regard to this choice? Also, I am planning to recycle my immersion chiller (50 foot coil of 1/2 inch copper) as a prechiller. (The tap water down here easily hits 80 degrees in the summer.) Are there any potential problems I should be looking out for? Thanks in advance for your help.

No match for a real fridge or freezer but cheap. I built one a few months ago and just finished my first lager. I used the Wyeast 2112 California Lager yeast since is is good up to 65 F which is easy to keep in the chiller. A few more weeks of ageing and I'll know how it turned out.

Date: Mon, 19 Mar 2001 20:29:25 -0500 From: "Bob Sutton" <Bob.Sutton at fluor.com> Subject: Fridge vs. GFI (Part II) I want to thank everyone who responded to my fridge's GFI problems... and its related electrical code and safety issues interpretations. I followed several of the troubleshooting suggestions I received. First I plugged a hair dryer into the troublesome outlet, and it ran fine on the highest settings. Then I strung up a 100-ft extension cord from a second GFI circuit in the master bath - and plugged in the fridge... "click"... that circuit broke as well. For comparison, I hooked the hairdryer up to the extension cord and it ran fine on the second circuit. >From this, the problem appears to be with my fridge.. thanks to the "Fridge Guy", I have some additional troubleshooting suggestions to follow once I get my hands on a multimeter. Several folks suggested I use a conventional (non-GFI) receptacle. Maybe I'm anal, but if two independent GFI devices each trip when I plug in the fridge, I get a bit nervous circumventing what seems to be a "fault" of some sort... In the meantime, my carboy is resting comfortably in the confines of our kitchen fridge. My loving wife has been very supportive... until I mentioned that lagering could require six months...
