Date: Thu, 7 Dec 1995 21:25:37 +1000 From: merino at cynergy.com.au (Merino Lithographics) Subject: Steam Condensation Bob Cowan posted, >Steam injection: >Can one easily steam heat without injecting the steam into the mash/boil?. >Most of the heat comes from the latent heat of vaporization. Suppose you >use a sufficient length of copper to let the condensed water drain outside >the mashtun or kettle, or does that give you too much water hammer, and blow >your relief valve? For steam to condense at above 100C, it must be generated and transported under pressure. For steam to travel without condensation down lines that loose heat it must be superheated, to loose heat without becoming saturated. The superheated part can be accomplished without significant pressure( As described in HBD #1902), but condensation requires sufficient exchange area, a safe condensate trap and usually a pressurised system. This system falls under the ASME or Steam Regulations. You can't afford the engineering or the wages of the steam ticketed operator. You could get some condensation in a long coil in your tun or kettle, but you need pressure relief into the wort to avoid a high pressure system, or you waste most heat through some other pressure relief system, like open air venting. At low pressure the steam wouldn't condense until it was about 100C. Also, I wouldn't play with water hammer in a coil, it is like a gun. Messy, grumpy and possibly dangerous. Commercially pressure jackets are built around the kettle, with high pressure "dosing pumps" to recirculate the condensate as "feed water". A "calandria" or condensing device in the middle of the kettle is also used. It's a bit like an old fasion coffee perculator. You also need a controller on your fuel linked to your steam pressure. Also some means of "blowing down" concentrated water in the boiler. All this costs much more than simple steam injection. My suggestions in HBD #1902 can be upscaled to the DIY pubbrewery scale to avoid the extra capital costs of steam. Charlie (Brisbane, Australia) Return to table of contents

Date: Thu, 7 Dec 1995 09:09:00 -0500 From: jhewit at freenet.vcu.edu (Jeff Hewit) Subject: Using Dishwasher to Sanitize bottles A few issues ago, Mike Moss asked about using the dishwasher to sanitize bottles. I have been using the diswasher since I started home brewing, and have successfully bottled almost 20 batches so far. One key point is to start with clean bottles. I rinse out each bottle right after I pour a beer. It's much easier to rinse out yeast and sediment when it's wet than waiting for it to dry and harden. I then run the empty bottles through with the rest of the dishes before storing them. When I'm getting ready to bottle, I load all the bottles in the dishwasher. I run it through a full wash/rinse cycle, set with heat option, using B-Brite in the wash and bleach in the rinse. When it gets to the air dry stage, I interupt, and start over with a full wash/rinse/heat dry cycle, with no detergent or bleach to give the bottles a full rinse. After the dry cycle part is over, it takes forever for the bottles to cool. I recommend starting the process in the evening, letting the bottles cool over night, and bottling in the morning. I may be over doing it a bit, but there is almost no effort to this procedure. This is one part of the brewing process where I am happy to let the machines do the work. Hope this helps.

Date: Thu, 7 Dec 1995 08:28:03 -0600 (CST) From: Tom Leith <trl at wuerl.wustl.edu> Subject: New brewer wants advice about all grain Bob Tortajada asks some questions: > I would like to explore all grain and/or > full volume boiling and would like some advice. Well, you're in luck -- there's no shortage of advice on HBD. > 1) I see alot of talk about steam injection mashing with complicated > equipment. Is all grain really that much more complicated than extract > brewing? In a word, "no" -- its not "that much more complicated". Its only "somewhat more complicated". You can make it as complicated as you want, however. What mashers do is produce their own extract. When they're through doing that, the process is the same. > Is there an easier way to get started in all grain brewing > than building a steam injection system? Certainly. I've been mashing for several years, and I don't do steam injection, ever. The easiest thing to do is the single-temperature infusion. This method is particularly appropriate for British style beers, but I have made some very good Continential beers this way by choosing well-modified malts (I'm a big DeWolf fan). Note that many if not most microbreweries have no ability to heat their mash tuns -- they do single-temperature infusions. Here's what you do: fill up your mash tun with a measured amount of water at a known temperature, add your weighed-out grain also at a known temperature, stir for a bit, and it comes to rest at your selected mash temperature. Here is a *starting point* for you: I use 1-1/4 quarts of water per pound of grain every time I mash. My grain is about 50F because its in a cold room in my basement. The water needs to be 12 degrees above the mash temperature I want for this to work out. If I want a 153F mash, the water needs to be 153 + 12 = 165F. Note that your mash tun will absorb some heat too -- I heat my water a few degrees higher, pour it in my mash tun, and wait for it to fall back down to the target temperature. This heats the mash tun. Here is an equation I scarfed off the net awhile back (thanks to whoever posted it) -- you'll need to solve for T in order to use it. If you use the same ratio of water to grain, and your grain is about the same temperature every time you brew, you need solve this only once. Most grain will be 3-4% moisture when fresh. You may find by experience that you need to adjust a bit from the figure you calculate. It could be that your grain has absorbed moisture over time... Paraphased from _Malting and Brewing Science_ by Hough, Briggs and Stevens St + RT 1/2H Mash Temperature = --------- + ------ S + R S + R S - Specific heat of malt t - temperature of malt R - ratio of water to grist by weight T - temperature of the water (strike heat) H - slaking heat of the malt at mash temperature The formula is applicable to both centigrade and fahrenheit providing terms are expressed in the appropriate units, but the table below is for degrees F. The slaking heat is given at 150F, just use it as a close approximation no matter what your real mash temperature is going to be. FYI, water weighs 8-1/3# per gallon. Table 10.1: Specific heat and slaking heat of a malt at various moisture contents slaking heat at % moisture specific heat mashing temp of 150F 0 0.38 33.5 1 0.38 29.0 2 0.39 25.0 4 0.40 18.8 6 0.41 14.5 8 0.42 12.4 > 2) Is there a good source for malted grain? Several. Start at your local homebrew shop. If you order in quantity, they can probably give you a price competitive with mail order. Keep in mind that UPS will run about $.13/# if you ship 200# or more. The rates are higher if you ship less. If you want only 10# or so, the price is driven up by the labor involved in repackaging for you. > 3) Can I build a wort cooler out of a copper coil submerged in the wort > with cold tap water running through it? Absolutely. You'll want 50' of 1/4" ID copper tubing. You can make it yourself by coiling the tubing around a plastic bucket, or buy it already made up. It takes about 40 minutes to chill 5-1/2 gallons this way. You might want to buy the current Zymurgy Special Issue -- it covers all-grain brewing in detail. I'm also a fan of Dave Miller's books on the topic. > I realize these may be stupid questions but > I am new to this so please beer with me. ^^^^ NOPE!!

Date: Thu, 7 Dec 1995 09:55:16 -0500 From: PatrickM50 at aol.com Subject: priming qty/ FG Ken Koupal asks: >>>>> For the past 15 years I've been using Byron Burch's book's formula of 1/4 cup corn sugar per gallon (or 5/4 cup corn sugar, in 1-2 cups water.) I don't think I'm over-priming. If so, I've been doing it a long time. I know, it depends on the style and your tastes, but: 1. How much corn sugar / water would be considered over-priming? 2. How much corn sugar / water would be considered under-priming? 3. 3/4 cup, 5/4 cup, does it really matter that much (as long as it's not flat or bulging the caps or sweeter than you can stand)? <<<<<<<<< Byron's latest edition of his book "Brewing Quality Beers" suggests approx. a 3/4 cup corn sugar to 5 gal. priming ratio. If you are lagering your brew, he says you may wish to increase your priming sugar to a full cup. Ken then asks: <<<<<<< Question: Do you measure Final Gravity before or after adding the priming sugar? I guess it depends on how you define "final." Is there a standard source of Final Gravity definition? >>>>>>>>> For the record (CD?),I have always measured FG before priming.

This would cover the use of unmalted fermentables in both extract and all-grain brewing. While I'm digging out the net.wisdom from the HBD archives, I would also appreciate input from homebrewers who use adjuncts. I had never thought of using corn starch peanuts.

Date: Thu, 07 Dec 1995 09:42:45 -0600 From: MURPHYJ at ada.org Subject: Russian Beer Lovers Party. Fellow Homebrewers (and assumed beer lovers): Today's Chicago Tribune includes an article by James P. Gallagher, the Tribune's Moscow bureau chief. In the article he tells of a political party in Russia (one of 43 parties) trying to gain a foothold in the Russian parliament. This is the Beer Lovers Party and they blame vodka drinking among Russians for their current depressed economic and social situation. They claim that if more Russians were to drink beer instead of vodka, many of these problems would go away. The idea has begun to catch on throughout the country and chapters have popped up in dozens of Russian cities. Vladdimir Sanatin, head of the party's chapter in Saratov says, "Beer lovers are more stable and trustworthy. They're more sophisticated, more in touch with the modern world. Vodka makes people mean and aggressive, while beer leaves you feeling mellow." I think we should show our solidarity with these brave Russians, and do all we can to promote this enlightened viewpoint.

Date: Thu, 7 Dec 1995 09:02 EST From: CSS2 at OAS.PSU.EDU (SPEAKER.CURTIS) Subject: custom caps/belgian malt extract Hi all: A couple questions for the collective wisdom of the HBD... Does anyone know of a company that will custom print beer caps for homebrewers? I have a coworker who's brother brews and is interested in getting some caps made special for his brews. A review of back issues of ZYMURGY and BARLEYCORN failed to uncover anything like this. Plenty of folks will custom make labels, but I didn't see anyone who does caps. Any info would be appreciated... Question #2: On page 72 of the latest issue of ZYMURGY, the Home Brewery Co. is selling New! Belgian Abbey Malt Extract Syrup - $8.95 for 3.3#. Has anyone gotten an early sample of this stuff and could comment on it's quality? It is supposed to be made from 100% DeWolf-Cosyns Belgian barley. I'm very intrigued by this one. Again, any info greatly appreciated. And for any of you folks thinking about making the move to corny kegs - DO IT! It is so nice to wash, santize, rinse and fill ONE vessel; but moreover, you fill it one day, force carbonate, and can drink it the next day!!! Yes, it does improve with more time under CO2, but for most of us who have gotten used to waiting 2 weeks for proper bottle conditioning, this is a true revolation!

Date: Thu, 7 Dec 1995 09:37:45 -0500 (EST) From: Mitch Hogg <bu182 at freenet.toronto.on.ca> Subject: Beer Filters & Wine Filters: Are they the same? Now, I know how unnecessary most folks consider filtering beer to be, but I'd like to transport a few bottles over the Christmas season (share the wealth, y'know), and I'd like to avoid churning up bottle sediment in transit. So, I have a couple of questions... First, can a wine filter be used for filtering beer? I have access to one at the winemaking shop where I work, and it seems like it would be easy enough to bring down the beer and run it through. Second, if it is possible, at which stage should I filter it, and why? For example, will filtering leave enough yeast in the bottle for proper carbonation? (Wine, of course, is bottled to be "flat"). Should I filter before or after adding the priming DME/sugar? Et cetera, et cetera. I hope someone out there can help me with this. TIA for your help. Please respond here or through e-mail. Mitch.

Date: Thu, 7 Dec 95 11:40:14 EST From: tgaskell at e3sa.elab.syr.ge.com Subject: Re: EasyMasher Although this is my first post, I am a long time lurker. I want to extend my thanks to y'all for all of the sage advice that I have extracted from the HBD. My first all grain batch (a porter recipe that was published in the HBD, duh!) is in the secondary and is IMHO my best beer yet. I have tried to amass a library of reference manuals from Miller, Noonan, etc., to help me with my brewing, but I would venture to bet that posts from Al, Rob, Kinney, Phil, John, Kirk, AJ, Dion, George, Dave, Andy, etc., etc., etc., etc. have improved my beer more than all of the texts. Apologies to those folks I didn't mention, but they are numerous. Now on with my comments about modifying my EasyMasher: My all grain set up makes use of 2 EasyMashers, one in my mash/lauter tun the other in my sparge water tank, this setup makes for a very balanced flow. Like Paul in Al's post, I had air leaks around the tubing when attached to my EM. Another problem I had was that as the vinyl tubing heated and became more flexible it slipped off the EM spigot. To solve both of the shortcomings of my EM I used a small file to smooth out the casting marks on the end of the brass spigot that the tubing slips over. Then I used a triangular jewelers file to make a very shallow groove all of the way around the spigot about 1/8 inch from the end. This groove serves as a barb to hold the vinyl tubing in place. As the tubing warms and becomes flexible, it fills in the groove holding itself in place. I also speculate that the groove, along with the smoothed casting marks, make an airtight seal between the brass and vinyl. No more airleaks due to a venturi (or is it Bernoulli?). 8^) I have used my EMs for many partial mashes and one full blown all grain batch, and after the above modifications are made, my EMs are a very trouble free and useful part of my brew equipment.

Date: Thu, 7 Dec 95 14:00:09 EST From: scox at factset.com (Sean Cox) Subject: Wild yeasts Recently I made mention of using wild yeasts in my brewing, and I've been asked to make a larger post about such heresy :-) I got interested in trying "wild" mead after reading Gayre's book on mead and thinking about how simply people were able to make the stuff, versus how many "modern" folks make a big deal about it. This was compounded by cider season (you know the routine: fresh unpreserved cider, left in the back of the friDge for a couple weeks, Mmmmm ci-der) which got me thinking about really giving wild yeasts a shot. So here are the steps that got me going: 1) Acquire "raw" honey. This was accomplished by mentioning my need to my Mom, who got me a pound of unfiltered/unheated crystallized honey from a beekeeper near her house. 2) Remove bee bits from top of honey. Do not mention bee bits to wife. 3) Scrape the honey from its jar into the fermenter. 4) Add water to fermenter to get it about half full. 5) Screw cap onto fermenter (sounds dangerous, but read on!) 6) Shake a lot. Shake some more. 7) Remove cap from fermenter. Add water to about 3/4ths full. 8) Replace cap and shake a lot. *Note: Steps 4-8 are to dissolve the honey (duh) but also to oxygenate the * must (this is mead, thus must) to get things going. My apartment * is only slightly larger that the Genie's Lamp, so I work with 1 gal * batches, thus a fermenter small enough to shake this way, use your * own preferred oxygenation method, or don't, they'll grow anyway. :) 9) Remove cap and attach airlock. 10) Kick back for a couple weeks, then drink. Use the sediment from this batch (I racked it off the sediment before I began drinking it) in the next batch(es) of your target brew and see what happens! My experience so far has been really fast mead fermentations with lots of complex flavors. I haven't bothered to bottle any of this, usually I just pour from the fermenter into containers (growlers, cups, etc) and then go back and top up the fermenting mead with some honey/water and give it some time to digest its new food. The pale ale I currently have fermenting has not had as active a fermentation as I expected, but I figure I underpitched it as well, having no idea how much of the sediment is really yeast (or of that, useful yeast) I should have pitched a ton to be sure. Oh well, next time. So far, it's had a very sweet aroma from the fermenter (now in secondary, I'll report again after I bottle it this weekend). Finally, this is really a fun thing to do, but a word of caution. If you are the kind of person (you know who you are) who need to be sure of his FGs, or pales at the thought of a "random" aroma or flavor in a brew this is not for you. But if you want to "get in touch with your innner brewer" I'd definately suggest giving it a try. Especially since you'll get some "free" mead for your efforts :-) --Sean Hmm, I wonder if Wyeast or Yeast Labs will come out with a "wild" liquid yeast now... Hmm..

I bought the spigot/tube assembly, and drilled a hole in my 33 qt. enamel-on-steel kettle and installed the unit. Not a complete success; the kettle is of such thin metal that drilling a perfectly round hole is difficult, and the supplied fiber washer barely provides a waterproof connection. But it works---I have made about 10 batches of mostly Belgian abbey ales, and a couple batches of Porter. Expect somewhat less than 30 points/lb/gallon. I mash about 10-13 lbs of grain per batch, in order to get an OG around 55-65. The best things about Easymash: Only takes about 1 pint--1 quart to run clear, and it's convenient for step mashing on a propane burner. (I use the "Superb" 35,000BTU, very happy with it. I think you'd have scorching problems with one of the high-output cookers, these kettles are very thin steel). (Yeah, I use it outdoors, rain and all...) Mashing is really a no-brainer with this thing---run in 3 gallons of water, heat to 166, add 10-12 lbs of grist, turn off flame, leave it on the stove or cooker, and go read the Sunday paper or watch the Seahawks lose to Denver. At halftime, pump a little energy into the system, stir, and check temp-- usually get complete conversion in about 60-90 minutes. With this quantity of thermal mass, it loses heat very slowly, a bubble-wrap jacket is perfect insulation. I changed from mashing in a 6- gal plastic bucket with Phil's Phalse Bottom (wonder if Frederick's of Hollywood has asked to license the trademark?? ;-> ) and am happier with being able to pump heat into the mash on the stovetop than by adding hot water, etc. etc. (But if you like the simplicity of single infusion , you can make some great beer with the Phalse Bottom (TM)/plastic bucket system.) Easymash is also a nice vessel for bottling, but as noted in 1899, the seam on the spigot will introduce air into the wortstream unless you use a little hose-clamp on your tubing/spigot connection. I use the 15-inch brass Phil's Philler, and like it a lot, but it is getting a little sticky and sometimes I have to pull the tube shut between bottles. Yeah, I'm too cheap to go to a Sankey Keg system---or maybe I just like to lug a few bottles over to a friend's place :=)... I ran across an interesting product while rappelling down the North Face of my hardware store's 'winterizing' dep't---it's a sort of aluminized bubble wrap. You'll see it pictured in the ZYMURGY special issue on grains. It costs about $17 for a 24-inch wide roll, about 12 feet--enough to insulate your mash tun and sparge bucket, as well as your kettle. R-value is approximately 16-20. Better insulation than my old sleeping bag, and cleaner. Phil's siphon starter is an interesting idea and will fill a racking cane with iodophor in about 8 shakes---really great for that. But it doesn't want to fill the whole racking cane-6 ft siphon hose assembly. Maybe I'm notshaking the thing hard enough--I dunno. It leaks very slowly due to irregularities of the ball surface, but I am not having any contamination problems (yet). Geez, I'm sure sick of the Koch thread, let's move on !!! Our local Redhook is making a very interesting seasonal brew---they call it Double Stout, it's their (I think) Blackhook Porter with some locally roasted Starbuck's coffee. Wotta kick!!

I find lots of info on >British vs. American, but not Belgian. Can I use it as a base, or is the >enzyme count too low? The only American malt I use is Schreier Brewer's 2-row which I think is a good-quality, very neutral-tasting malt. DeWolf-Cosyns Belgian Pale Ale is slightly darker and also very neutral. You cannot make a very good Pale Ale from it if you use it alone. You can, however, do this with British malts which, to me, taste quite a bit more caramelly than the Belgian or American malts. Makes sense if you consider the Lovibond -- the Am. and Belg. are paler which implies they have been kilned less/cooler. You can use DWC PA as a base malt -- it has plenty of enzymes for itself and a little more. I don't have my charts here, but my guess is that it is slightly more enzymatic than English Pale Ale malts, but less than US. It's all a tradeoff -- the US growers use more fertilizers (I'm told) than the Europeans and the higher protein levels show it. Higher protein means higher enzymes (enzymes are proteins) in general. >2) I "harvested" some yeast from the bottom of a Sierra Nevada Pale Ale >bottle, just to see if it would work.

As I've posted before, size of starter makes a difference because the heat generated by the yeast warms the wort if you get a good, fast start. >3) I am using an Easymasher in a canning kettle.

If you take 7 gallons and boil it down to 5 you should get the 30+ points from the EasyMasher(tm). Also, stale grain can lose you 10% or more. How do you store the grain?

I would have thought that >siphoning on top of it in the bottling bucket would sufficiently mix it. >Apparently, I am missing the boat here somehow. I leave the DME for making starters and extract batches. I use corn sugar, but uneven carbonation can be a problem in the mixing, but it can also be a problem with your capper or if you boil your bottlecaps for sanitation. The heat can mess up the linings and completely ruin the absorbing capabilities of oxygen-absorber caps. *** Bob writes: >Is there an easier way to get started in all grain brewing than >building a steam injection system? Yes, infusion mashing. >Is there a good source for malted grain? Homebrewing supply store or mailorder -- see the back of brewing magazines for a million suppliers. >Can I build a wort cooler out of a copper coil submerged in the wort >with cold tap water running through it? Yes, that's called an immersion chiller. I think that you should get yourself a good basic text on homebrewing -- Papazian's New Complete Joy of Homebrewing or Miller's Homebrewer's Guide or Brewing the World's Great Beers should give you the information you need to move from extract to all-grain. Your question are valid but are more easily answered in books and than via the HBD. Think of HBD as a place to answer questions and discuss ideas that are not covered in books (yet ;^). Al.

Date: Thu, 7 Dec 1995 13:17:36 -0800 (PST) From: Jim Cave <CAVE at PSC.ORG> Subject: Overpitching? Andy Walsh indicated in the last Digest that he a problem with one of his ferments. He alleges overpitching as a cause. I'm not convinced this was the problem, as he indicates a high fermentation temperature. This he believes was due to the temperatures generated by the metabolism of the yeast. Off Flavours and aromas (banana esters) were indicated. First, what was the initial temperature of the wort? Was it 60F or was it 70 F.? Was the fridge operating properly? I'd have a good look at the fridge. I supect temperature being the problem rather than pitching rates. The high gravity is a possible cause, but 1.068 is not a high gravity beer and the yeast should not have trouble fermenting this gravity rapidly. Has anyone out there tried measuring fermentation temperature changes that are completely attributable to fermentation, (i.e. delta ambient-fermentation differences)? I recall Noonan (in his lager book) saying that banana ester formation was due to some factor in wort composition, but it's been some time since I read this book. I routinely pitch massive quantities of yeast (yes, I use the entire primary's yeast too) and never have had a serious ester problem as a result. The last time I did this was with an IPA of starting gravity 1.061, and an ambient temperature of 66-68 F. The yeast used was NCYC 1332. The result was successful (he said humbly). Ester levels were appropriately English. Jim Cave Return to table of contents

I know the wyeast one > makes great banana beer (I refuse to use it for that reason), but what about > YeastLabs? Well, I have used the Yeast Lab Belgian on a *few* occasions........ At a 60F air temp. the wort temp. could easily rise out of control. Which looks to me like a more accurate discription of what happened here. You measured 28C (>82F)! At 28C I'll bet you got a bunch of bananas. Your presented data: 1) high gravity 2) 28C, 3) 36 hour thermonuclear fermentation and 4) BANANA!!! all point to a high temperature fermentation with this strain, not overpitching. Of course, since you did pitch a good yeast dose, the fermentation went out of control more easily. It sounds like you need a more efficient cooling system with your present fermenter. You might try an open ferment with submerged copper cooling (modified wort chiller) coils. A small amount of cold water flowing will help to slow down the temperature rise, keep the yeast from climbing out of the fermenter and cut the bananas. DanMcC Return to table of contents

My questions are: >How many breweries out there use decoction mashing(those which do not use >adjuncts)? Have any of you ran side by side comparisons and noticed >differences? I don't know about the breweries but the reason I use decoction mashing sometimes (when brewing lagers) is that it gives a completely different character to the beer. I don't worry to much about the malt I get here in Sweden being under-modified. Another aspect is the fact that it's an easy way of raising the temperture of the mash. I used to do step-infusions before but found it to hard hitting the right temperature without having to add too much boiling water and thereby diluting the mash too much. I sometimes even had to add cold water to lower it, which was a bit of a nuisance and a waste of energy. But then again, this could of course happen when you decoction-mash...

It sounds like interesting stuff, but totally unlike the beer-like beverage that has been served to me by Russian friends. Their kwass was made from dark rye bread, not mare's milk. It was so much like beer that I think it must properly be considered a type of beer. Does anyone know anything this type of kwass?
