Although it may seem to be counter intuitive, your thesis is wrong. The important consideration here is the partial pressure of the individual gasses, not of the total gasses. Air is approximate 20% oxygen and air pressure at sea level is about 14.7 psi. Thus the partial pressure of oxygen in air is about 3 psi (.147 x 20). Assuming the bottled beer contains no oxygen, there will be an oxygen pressure gradient of 3 psi across the plastic bottle from the outside in. It matters not what the carbon dioxide pressure on the inside is. The oxygen will diffuse in over time. - -- Phil _____________________________________________________________ Philip Gravel pgravel at mcs.com Return to table of contents
Date: Sun, 15 Jan 1995 10:21:34 -0500 From: TomF775202 at aol.com Subject: Re: Keg setup My advice to those setting up for kegs is to use the same size line for beer and Co2. I use Johnson 3/16 id hose for both.You should also use quick disconnects with 1/4 in. flare fittings instead of just hose barbs. This way you need not to have two different sizes of fittings and hoses. I carbonate a 20-30 lbs and dispense at 10 lbs. As foar as fridge size I use an apartment sized fridge that fits two cornelius kegs as well as about two cases of beer. Return to table of contents
Date: Sun, 15 Jan 1995 12:01:29 -0500 From: HOMEBRE973 at aol.com Subject: yeasts, torrefied, mashes etc. I have been reading the net for a while but lately have not taken an active part except via e-mail. So first an answer, than a few questions. A few issues back, Chuck M asked about the differences in flavor between infusion and decoction mashes. I have recently done both using D-C malts. While the infusion is mush easier, I do seem to get a much more rounded and malty flavor doing a decoction mash. Has anyone made direct comparisons between Wyeast 1098 (British Ale) and Wyeast 1028 (London Ale) with regards to flavor profile and body or maltiness. I know what the archives says, but I am looking for people who have direct experience with these. What does Torrefied mean? -- i.e. torrefied wheat or torrefied barley? Had two interesting beers last night at a local Mexican restaurant: Yong's SPecial London Ale and Chicago Porter. The Young's Special London was fantastic with a great malty flavor and mouth feel with a touch of diacetyl I love. The Chicago Porter was quite good. it had a nice smoothness and flavor to begin with but ended either a bit too bitter or slightly astingent. I have not seen Chicago's beers here before. Can anyone give a brief description of the brewery, styles, and their opinion of the quality of their brews? A recipe I have from "Brew Your Own Real Ale at Home" (an excellent book!) uses 1 lb. Golden Syrup (invert sugar). They sell it at the gourmet store for $5/lb. too much in my humble opinion. Would the collective wisdom of the digest substitute cane sugar, dry malt extact, or just add more pale ale malt for this all-grain Fuller's London Pride clone? Last but not least, I thought the discussion on water chemistry and buffering were excellent and helped put the HBD back on course! Andy Kligerman homebre973 at aol Return to table of contents
Date: Sun, 15 Jan 1995 13:12:57 -0400 From: richard frederick hand <ac081 at cfn.cs.dal.ca> Subject: 5 litre mini-kegs Need some advice from those who have had experience with these kegs. I run a beer (& wine) supply store and over a 24 hour period 2 customers have had problems with them. The first one claims that the tap part leaks CO2 when a new cartridge is first put in. He finds he has to use a lot of muscle to keep it in place and to keep it from leaking until he replaces the cartidge holder. He suggests there is a design flaw in the cartridge mechanism and recommends that there should be a rubber washer to hold the cartridge in place, as in the Edme plastic barrels. Has anyone else experienced this problem? The second customer came in with two exploded kegs. He claims they were not overprimed, and that his other barrels that held brew from the same batch were OK. I suspect that maybe the two kegs were somehow shaken or is there a flaw in some kegs? They were primed with the kraeusening method, if that matters. Has anyone done tests on the amount of priming these kegs can stand? Rick Hand Halifax, N.S. Return to table of contents

I got it about 15 years ago from a guy who called himself Sourdough Jack and was on a mission to put a sourdough pot in every home. He produced a crude cookbook and distributed starter cultures of the wild yeast. He was given his sourdough pot in the 1940's from an old "Alaskan Sourdough" who had it in his possession for 50 years. I've occasionally entertained the idea of using it to brew but have never done it. Has anyone tried a wild "sourdough" yeast for brewing? Regards, Dave Sanderson Return to table of contents

Santos" <jesantos at WPI.EDU> Subject: Re: Misconceptions about misconceptions Thanks Jeff and Domenick, In my previous post, I put out the idea that the pressure exerted in a plastic bottle would prevent the Oxygen permeating into the brew. As an engineering student I should have known that common sense does not always rule. Thanks to some quick responses I had the opportunity to review my basic chemistry and correct the misconceptions I had. To clarify the issue, the pressure of the CO2 in the bottle has no bearing on the O2 transfer between bottle and atmosphere. Because the concentration of O2 is close to nil O2 WILLpermeate the plastic until equilibrium is attained between the concentration in the beer and the atmospheric concentration surrounding the bottle. I have learned my chemistry lesson of the day! BTW, If I understand this correctly the pressure in the plastic bottle would increase due to the excess O2 pressure. Could this be a cause for concern?

One holds pressure okay, but the other one leaks from both poppets. This isn't a problem as long as the keg is hooked up for dispensing, since the gas-in and liquid-out fittings act as an additional check to keep the keg from leaking. But the keg won't hold pressure if left "as is" for lagering or conditioning. Rather than track down new poppets (which can be a pain for Firestone kegs, since they aren't one-size-fits-all) I have kludged the following solution. I screwed 7/8" acorn nuts over the "connect to hose" ends of two THREADED quick-disconnects (one red, one white). I then hooked up the disconnects to the appropriate poppets, and the acorn nuts keep gas from leaving the keg. I had the disconnects just laying around, and the acorn nuts cost $0.28 each -- an economical and effective fix to an annoying problem. You could probably come up with a similarly cheap way of modifiying two quick-disconnects with hose barbs. I also follow Papazian's practice of adding 5 PSI of gas to the newly-kegged beer in order to seal the o-ring on the lid of the keg. I have found that this can be another source of keg pressure leakage, so beginning keggers beware. Sure beats bottling, though.

Among my purchases was 5 lbs of Aromatic Malt. Now, after reading Dr. Fix's excellent article in BT, I know the malt is dark (25.7 Lov), is on the high side for total protein, and has enough enzymes to convert itself. Other than that, I haven't the slightest. Anyone out there have any experience with this malt? What sort of recipes is it used in, and in what quantities? The article mentioned "unique flavor contribution"; any comments? BTW, D-C's Munich malt makes an excellent grain bill addition for a Northern Brown Ale (heresy???).

It seemed to work ok for about 2-3 tests, but has since been giving inaccurate readings. It has gotten so bad that I can't even calibrate it anymore. There have been several other postings concerning this instruments poor quality. I have seen this same unit advertised for gardeners interested in checking soil PH. It may be that it works ok when the temperature stays below 100F, but it should not have been advertised and sold to homebrewers if this is the case. I plan to write the manufacturer and return the unit. I will ask for a refund or credit to upgrade the unit. Does anyone have the mailing address for Hanna Instruments?

Date: Mon, 16 Jan 1995 08:09:28 -0600 From: keithfrank at dow.com (Keith Frank) Subject: Using rice ****** from Bruce DeBolt ******* Someone requested tips for using rice a couple weeks ago. I've used it as a minor part of the fermentables for a cream ale with good success. These techniques were suggested to me by Norman Farrell. Basically you boil one lb of rice in one gallon of water for about 25-30 minutes to gelatinize it. Cool to about 165F, then add one lb of pale 2-row malt. The temperature settles in the mid-150's. The fun part is seeing a gooey gelatinous mass (boiled rice) convert to a thinner, sweeter solution within minutes. I let it sit for 30-60 minutes for conversion. Dump this in with the rest of your mash, or heat up to mash out temp. and add then. Sometimes I do this the night before to make brew day easier, refrigerate, then reheat to mash out temp. the next day. The cream ale recipe: Grain - 8 lb 2-row pale, 1.0 - 1.5 lb rice; Hops - Cascade (6.1a) 0.7 oz. at 60 min., 0.5 oz. at 5 min; Yeast - Wyeast 1033 European Ale; OG 1.045-1.050, FG 1.013. Mash 2-row at 156-158 for one hour. A good beer for parties for the light lager drinkers. Dave Miller wrote a short summary about how to work with rice in Brewing Techniques last year, but I don't have the reference handy. I'd like to thank Kelly Jones for the excellent post on low alcohol beer last week. Bruce DeBolt c/o keithfrank at dow.com Return to table of contents

This may sound like an ad but I think this is the greatest thing since sliced bread for anyone who suffers through soaking and scraping labels off of there homebrew. 3M, the folks that make the anoying yellow PostIt notes stuck all over everything, are now selling that reusable adhesive in the form of a glue stick. You can print labels on regular paper, apply a little glue, and stick to to bottle. When your done, with your creation, just pull the label off without soaking or scraping. And, it leaves little or no residue on the outside of the bottle. This stuff is great for anyone who does label their beers. Andy Return to table of contents
Date: Mon, 16 Jan 1995 10:37:35 -0500 (EST) From: Eugene Sonn <eugene at sccs.swarthmore.edu> Subject: Mini-keg review Happy New Year to the HBD, Since several people have asked about the mini-kegs, I thought I would give a review of the system I got for a Christmas present. I received a mini-keg system from the Williams Brewing catalog. It comes with one mini-keg, a stopper/bung to close it up, a combination tap system which can use either 8 g CO2 cartridges or a hand pump, a 10 pack of the CO2 cartidges, a tub of Williams keg lube and excellent instructions written by Williams. The whole kit costs $60. I put an oatmeal stout into the keg and it turned out great. One CO2 charge will dispense about half of the keg. Then you can use another charge or if you are only going to have the beer around for 6 days or so, you can use the hand pump. The protective layer of CO2 provided by the first charge kept the second half of my keg good for over a week. The keg is easy to use, but a down side is that once it's tapped, you cannot un-tap it. The bung in the top of the keg has a plastic "cork" in the center which you push into the keg when you put the tap in. The tap's intake tube fits in this hole in the bung and the tap attaches to the lips on the outside rim of the keg. If you took the tap off, you would have a keg with a 1/4 inch hole in the top. The CO2 dispenser works well. The only trouble I had was when early on I wanted to take off the CO2 part, but when I did, pressure leaked out from the keg. This might be my fault since I did not lube the 1-way valve in the keg as the instructions said I should. The actual tap or dispensing valve works great, I had not leak problems. I would definitely recommend this system to anyone who is sick of bottling but does not have the money or fridge space for a soda keg system. From what I've seen, the Williams starting set is a good buy, but I have seen the actual kegs for less money at my local brew store. I would definitely recommend the combination tap because of it's flexibility and relatively low price.

To add one more data point to Bobs question about honey, I usually add two pounds of honey when I do use it. I have read (Papazian) that the addition of honey can lead to a more complete fermentation. If this is true then I would avoid using honey to prime with because it could cause gushers or gernades.

My feeling is <that this is asking for slow, stuck fermentations, particularly at the <low end of the range. It depends. I routinely ferement Amreican ale yeast at 58-60F pitching temp, 63-65F ambient, with winter ferments climbing to 64-65F. Works fine (despite lots of folks saying this yeast slows down too much at low temps). I have also recently done the same using Gales yeast (thanks Dan!), and it worked fine. What is essential is the same ol brewers 101: aeriate and pitch adequate cell counts. If you do this with an all grain beer there should be little problems, but the results will be cleaner. BTW, the Gales was not "clean" at this temp, it was typically English, minerally, agressive oak and tannin dryness. Quite something. Alvin asks about scaling up batch size: <I've been thinking about moving up from 5 gallon batches and possibly going <into production at brewpub level. I was wondering if there are formulas to <convert 5 gallon recipes up to larger batches (10 barrels and up)? If so, <is there software available that will do this? Is there a listing anywhere <of used brewpub equipment? etc. etc. It is my experience that scaling up recipes does not work well at the 10 gal - 1 BBl level, much less what might occur at bigger jumps. Much of this is due to efficiency of scale, but much is also due to the brewery itself. You have to bite the bullet, take your best educated guess and finely tune the results. This is part of the fun of brewing, if you did it in smaller batches, you should have the skills to replicate it, but it might take a few brews to get real close. BTW, this same thing happens with fluctuations in hop supplies and malt changes that occur. You always have to be on top of this to be consistent.

Date: Mon, 16 Jan 1995 11:31:22 -0600 (CST) From: winstead%brauerei at cs.tulane.edu (Teddy Winstead) Subject: Sanitary Welding/Water Help Hey there. I hope everyone had a happy holiday season! OK, prepare for a long post. First of all, I've been meaning to post this information about sanitary welding for some time. This comes from a gentleman named Jim Driscoll who is building a brewery in the Northeast (New Jersey, I think). He asks that I not give out his e-mail address, but that I collect any replies that this generates, and forward them to him. So, if you have questions, send them my way. By the way, he is using a Miller Synchrowave welder to do all this work. It's a big, heavy-duty TIG welder with an extremely hefty price tag. Here it goes (this was all extracted from an e-mail message to me) -- I have been unable to find any book on sanitary welding. If you do find something of that sort I would appreciate hearing about it. Your post didn't give much of a clue as to your knowledge of metal fabrication, so here goes an explanation that may or may not be optimally intelligible or useful: The material I use is type 304, but some prefer 304L for increased weldability. I am usually using 12ga, but for a homebrew setup 18ga is about as thin as I would go to still be easily weldable. For this gauge, the mill finish, 2B, should be sufficient for homebrewing, but you can get a #3 or better yet a #4 finish for the inside if you are feeling generous. I would recommend getting the material with removable protective coating for the inside that will protect the finish while you build the equipment. You can cut it away from joints with a home-made copper blade made by grinding a squashed piece of copper tube. Never let anything made of mild steel touch your stainless, and don't use anything that has touched mild steel on it either (e.g. a grinding wheel). The welding method of choice is TIG or GTAW. Be scrupulous about your tungsten! always grind it to a point on a grinding wheel reserved for only tungsten, and if it it touches the weld puddle immediately cut off and regrind the tip. I butt weld joints. For tanks tack weld the compennents into position with as close a fitup as possible--it is worth the trouble. I use hydraulic spreaders and cargo load straps to bring things into position/into round. I then weld the inside with filler rod, penetrating say 2/3 of the joint, then weld the outside with filler. I am moving toward backing the joint on the outside with flux or a consumable weld backing material and then making one pass on the interior. Alternatively, you could back it with inert gas, but this won't support the weld puddle. After welding I use what I think are called polifan wheels from Pferd abrasives mounted on an angle grinder to grind/finish the weld on the interior. To get a better finish I use flap wheels or non-woven nylon abrasive wheels mounted on a straight grinder afterwards. After this has been done, the weld should not be visible, there sould be no pits or high spots. About the only thing you should be able to detect is a difference in finish in the area of the weld. For a really fine finish you can send the finished assembly to an elecropolisher, but unless you are Coors, this is usally reserved only for yeast propagation plants. Now here comes the tricky part. Most people will tell you that you must passivate the heat affected zone, by which they mean that the free iron brought to the surface by the welding process is removed and the protective chromium oxide layer is restored. My experience is that if the heat affected zone is finished well with suitable asbrasive materials the joint will not corrode. For your purposes you can probably use it as finished, and if you note any corrosion, it can be removed with the green hand pads sold at your local grocery store for dishwashing. If you insist on passivating it, I can tell you how it can be done, but it requires using dangerous acids. You should be aware that "fresh" stainless steel has a taste. When commercial brewers bring a new piece of equipment on-line, they first fill it with finished beer, let it sit a bit, and then discard the beer. (End quote) - ------------ Next, I really, really need some help from you chemist types out there. I've been using Kentwood spring water for some time now in my brews. I recenyly got a water analysis sheet from them, but all of the values are in mg/L and not ppm (parts per million). In an effort to correct the values to ppm, I did the following math -- 1. Compute number of moles of H2O per liter (55.3 mol/L). 2. Compute number of moles of the given substance to the correct number of moles for that substance. 3. Compute the ratio of the two, hoping it would produce the desired result. THIS DIDN'T WORK! What did I do wrong, and what is the correct way to convert between the two measurements? Here are some of the values from my water analysis sheet -- Alkalinity as CaCO3 13 mg/L Calcium 2.2 mg/L Chloride 2.5 mg/L Iron <0.01 mg/L Magnesium 0.99 mg/L Sodium 6.2 mg/L Sulfur, Sulfate 6.2 mg/L Solids, Total Dissolved 44 mg/L Return to table of contents

Date: Mon, 16 Jan 95 12:54:51 EST From: dweller at GVSU.EDU (RONALD DWELLE) Subject: infections/licorice Two notes: Somebody said infections always get worse. Last fall I had what my local brewfriends and I finally diagnosed as a yeast problem--some sort of infection or mutation or perversion. Beer tasted like grapefruit juice after it was done. This happened in two batches, the second batch brewed from yeast recovered from the first batch. I nearly tossed both batches but didn't need the bottles immediately so let them sit. Three months later, the first batch is nearly drinkable. Thus the rule: "Don't give up the shit..." On licorice, I've not used it a lot, but I think there's quite a difference in potency of the various sticks. One stick I used (in two separate halves) had so much flavor it overwhelmed everything else in the beer. The next stick I used seemed almost flavorless, with a half giving just a hint in a five-gallon batch. I suspected the sticks might have been of radically different ages. I don't know how to prejudge the potency. Someone also said a stick didn't dissolve in the boil. Certainly never had that problem! I just throw the lump in. I've also tried a couple different kids of licorice with no luck--brewers licorice sticks seem to be the only thing that work in porters and stouts.

Date: Mon, 16 Jan 95 12:00:50 CST From: BigBrad <BPLUMMER at SYSUBMC.BMC.COM> Subject: cooler collar Hi, all. I recently asked if there was interest in the freezer 'collar' I installed on my chest freezer. I received numerous requests asking for a description. Thus the following: 1st prob: How to cool soda kegs of homebrew. 2nd prob: How to cool more kegs than what a normal 'fridge will hold. (I like to have several on tap) Answer: Get a chest freezer (no shelves or 'crispers' to hassle with) and add an external temp controller. Mine is a 15 cu ft model that will hold 7 kegs and the 5 lb Co2 bottle. The temp controller is a White-Rodgers(sp?) and it says it will hold the temp range to 4 deg. 3rd prob: Now that I am the proud owner of a 7-keg storage facility, where do I put the serving taps? Not the sides, as the cooling coils are located there. I can cut into the lid but must install a 'standard'(cylinder) to do so. These would work fine except the cost is about $70 per and I would probably need 3. The 'standards' are sold sans taps so I would also have to purchase those. I decided there had to be a better/less-expensive way. Answer: I decided to raise the level of the lid and install a spacer that could be drilled and fitted with taps. This 'collar' had to be insulated and would have to have a smooth surface on top to allow the lid to sit on it and seal well. I also did not want to attach the collar in such a way as it would become permanent. My original design called for 2 pieces of plywood with foam insulation sandwiched between to sit down over the top of the freezer box. This idea went by the wayside when a friend said that 2" of oak would provide me with a better looking end product without sacrificing the insulation factor (oak is denser than pine). The oak won out. The collar is 6" high and 1 3/4" thick. there is a 1/4" lip on the outside bottom of each side and front. Insert inadaquate ascii graphics here: ______ | | | | | | | | collar cross-section | | | | |_____|| ||<--- lip **** NOTE **** IMPORTANT FACTOID TO BE PRESENTED **** There is no lip on the back as the outside surface MUST be flush with the back of the freezer box to allow the hinges to be reinstalled. The sides of the collar can be joined as you see fit(pun) but we did ours like this: ___ |-------------------- | | | | | | | | |___ Well, you get the idea. | |___ | | | | | | | | | |___________ | | | | | | | | We used a soft, putty-type gasket material between the collar and the freezer box. This gives us a good seal that will not become permanent. We then put the lid w/hinges on top of the collar. We aligned the hinges to match up with the holes in the freezer box. Since the hinges were now 6" higher, we had to drill 2 new holes in the hinges towards the bottom were they would match up with the top hinge holes on the freezer box. This done, we attached the hinges to the freezer box with the original screws. We then drilled pilot holes in the oak where the top hinge holes were and attached using 3/4" wood screws. With the lips on the collar bottom and the attachment of the hinges to both the freezer and the collar, it's not going anywhere. I drilled a hole in the back of the collar to allow the temp controller probe to be inserted. I then plugged the hole with insulation. I attached the body of the temp controller to the collar in the back where it is out of sight but within easy reach. I will be installing a drip tray by suspending it from the collar and using double faced tape to attach it to the freezer box (remembering to leave enough room for the pitchers that will invariably be used during parties). I now have a beautiful place for the taps to be mounted and have not defaced the freezer. Sorry for the long post but there seemed to be an interest. Now, back to the actual brewing ...... - ------------------------------------------------------------------ Brad Plummer \ As I picked myself off the floor, I / BMC Software, Inc. \ realized I should have said, "Ma'am, / Houston, Texas \ that's mighty impressive FOAM you / bplummer at sysubmc.bmc.com \ created in my beer glass." / - ------------------------------------------------------------------ Return to table of contents
Date: Mon, 16 Jan 1995 14:38:30 EST From: Bob Bessette <bessette at hawk.uicc.com> Subject: Trickle Sparge update, starter, etc... Fellow Brewers, For those of you who remember my first all-grain venture and the "trickle sparge" which lasted over 2 hours this is just an update. I tasted the beer that I made on that day and it has far exceeded my expectations. I thought it would take a while before I would make a beer that was as enjoyable as my extract brews. Well, my first all-grain beer is MUCH better than any extract brew that I have ever made. The major difference is that the all-grain beer is much fuller and has more body to it. I am very happy with it and more excited than ever about doing all-grain beers. By the way, I made my 2nd all-grain beer over the weekend and the sparge was exceedingly quicker this time. I made sure that I held down the false bottom with a spoon until all of the grains had been doled in. I also used a Bru-Heat for the first time ever. A co-worker of mine lent me his and I found it to be very easy to use and very convenient in that I could do everything in my kitchen. I typically use a King Cooker outside but with the convenience of the Bru-Heat I was able to brew into the wee hours of the morning without disrupting my household during the day. I am looking forward to seeing how the beer turns out as well. One word of caution, if you set the Bru-Heat on the kitchen floor you might want to prop it up on two pieces of wood. The heat that it generated actually left a small stain on my acrylic kitchen floor. Since the floor is made up of squares I can easily replace one of the squares. Another thing I tried was doing a starter with the Wyeast. I used a 22 oz beer bottle that I disinfected with B-Bright. I boiled up about 10 oz of water with a couple of tablespoons of DME and let it cool in the bottle. I popped the Wyeast the night before and it had swelled a bit since this was about 17 hours after I popped it. I then pitched the yeast into the bottle and put on an airlock. I made sure everything was disinfected prior to pitching. About 12 hours later I pitched the contents of the bottle. I did not have any noticeable signs of fermentation other than some sediment on the bottom of the bottle. As a result of doing the starter I think I cut my lag time from about 36 hours to 24 hours. I think next time I will make the starter even sooner so that there is more visible fermentation in the starter and, as a result, less lag time in my primary. I also bought a 6 gallon glass carboy over the weekend and it is quite extraordinary to see the fermentation. It is very vigorous and it is about 28 hours after pitching. So, all in all, I am extremely pleased with the gains I have made not only in knowledge of making beer but what appears to be in the quality of the beer as well. All-grain is the way to go. I recommend it highly. I can't wait to do my next one... Bob Bessette (all-grainer and proud of it...)

Date: Mon, 16 Jan 95 14:46:46 EST From: Eamonn McKernan <eamonn at rainbow.physics.utoronto.ca> Subject: yeast / Boddington ale / Unspoken Passion / bottles There was some talk about not culturing yeast from strong beers. I bought a liquid yeast for a stout (O.G. ~1065 if memory serves) I wanted to use it again by culturing from a bottle of the stuff, but am worried about mutated yeast. Any thoughts? Tried Boddington ale this weekend from a can. Nice stuff. It has that amazing creamy head like Guinness. The can had a weird platic contraption in the bottom for pressure or something. Anyone know what it does? Further, how would one go about getting a head like that on homebrew? I might even try my hand at a Boddington imitation if there's a good all-grain recipe out there. Anyone? Anyone ever made Papazian's unspoken Passion Imperial stout? 11 lbs of raspberries in 6 gal of beer. 35 HBU's was way too much. The stuff's far too bitter. I might try diluting with the remains of my porter. Similar experiences with bitterness anyone? Finally, in case anyone's interested in a summary of the bottle deposit responses, no one had any sure answers. No one knows how much a bottle costs breweries. Some people said that the breweries might not be collecting the deposit money anyways (Upon reflection, this seems likely). It was suggested that the little bumps on the bottom of the bottle were an indication of how many times it's been re-used. After a certain number of uses, it has to get melted down because it's no longer sanitary. In conclusion: many many theories, but no certain answers. Thanks for all the responses!

I think I would try I think you are confusing Chipotle (note correct spelling) with Chiltepin. Chipotle's are indeed smoked Jalapeno peppers, and are NOT "tiny peppers". Chiltepins, also called (Chilteqpin, Tepin, Bird's Eye) ARE tiny peppers, and quite hot, too. They are "wild" peppers and are generally not cultivated.

I hope). I'm sure my description to Mark on measuring these tiny peppers by the tablespoon was confusing at best! (Chile Pequin's do have a 'naturally occuring' smokey flavor... so perhaps that fact addled my brain). I suppose my advice to Mark would be about the same. Chipolte's are bought in small cans (4 oz?). They are packed with thick, red, smokey sauce. I would think throwing in one can at the end of a boil would give plenty of smokey character to a pale ale.
