Dear fellow Homebrewers, I beseech you, after a weeklong search for information....what is the easiest way for me to convert my ALUMINUM (I know, hopefully I won't forget how to make beer) Keg to a shiny brewpot. I have a general clue, I.E. Cut the top out (so that a lid will fit) then put hole near the bottom, attach a flow controller (ball valve) on the outside, with a copper tube inside, cut so that wort flows out but trub and hop pellets do not......Now, the big question is, how. I spent over an hour staring at my options at Home Despot, and since no one offered to help (quelle suprise)....I am lost. I found something called a 1/2 inch ball valve (brass), but how to connect this to a copper tube inside the keg.....Oh, and did I mention I don't want to solder, would like to be able to just tighten everything down to make it leak proof. So that is my dillema. Any caveats about using aluminum, brass and copper in my solution will bve considered, as long as a viable option is also included. Please Obi-HBD-Wan, you're my only hope.

I have a serving fridge for keg beers (and SWMBO's seltser) but would like to use CO2 outside this in the form of a nozzle for flooding and maybe blow cleaning, a separate gas in fitting for driving cleaning solutions through kegs and a system to panic carbonate my real ale when I was too late to rack into the cask:-( . I realise that the flow stopper would only be on the female (tank) side of the connector and that I cannot disconnect a pressurised keg, but do you see any other problems? Also, does anybody know of an inline regulator that could be used to differentiate pressure between kegs?

I think that the average page size of an informational digest or document from elsewhere on the net is quite the opposite: Over the 32K size. I have a Palm and using direct downloads and another document reader, I've routinely read 90K+ documents without issue. I think the problem is that AvantGo (or should that be AvantStop?), needs to address their size issue as this limit impacts far FAR more than just the HBD. That to me is where the real issue is. I am the author, maintainer (or idiot), that created the hbd2html filter and really do not even want to think about re-writing it to generate another form of the digest just for a few readers. Get a document reader (several to choose from on the Palm software sites), then download the zipped version via ftp from hbd.org (it will be decompressed automatically if you leave off the .gz extension). Transfer to your Palm via the hotsync. Yeah, it's may seem a bit cumbersome, but it works nicely. As I said, the best solution is for AvantGo and any other of these software folks to fix THEIR limitation as this problem is not solely caused by a large HBD in html form. This is going to be a problem with probably the majority of information pages on the internet. Besides, there are only so many spare minutes in a day and this is not one area I think is deserving of using those minute. Please don't bring this up again on the digest. Reserve this space for beer discussions. Send all further discussions on this topic to janitor@hbd.org. I'll be glad (and Pat will probably read with amusement), to answer questions or continue this via the janitor@hbd.org address. Karl F.

Gray-wacke, Schmay-wacke, that's a granite, no way around it, it is not even close to a graywacke. A graywacke is a sandstone, sedimentary, while granite is igneous (as described in your post). I could certainly see the wort "volcanoing" out of the top at 800f (even more so at 1200C). That would be a fun demonstration at the next homebrew competition.

There has been considerable discussion over the years on using plastic carboys. It seems that sanitation is the problem. There was an interesting column in the Nov/Dec Zymurgy from a long-time brewer in Calif who used medical/food grade plastic bags as a liner to ferment in the plastic carboys. It seems so brilliant it makes you wonder why all homebrewers aren't doing it. I wrote about it on HBD #3469 on Nov 3rd. The writer of the column heard about my post and corresponded privately with me. I have not yet sought out disposable, plastic liners for myself but I am still considering it. The advantages to using this method would be greater safety, less heavy lifting, no cleaning and easier yeast retrieval. If you would like more details of our conversation, please drop me a line.

Several responses refer to John Palmer's excellent online book www.howtobrew.com. Using equations published by others, I wrote a javascript calculator for this purpose. I added a thermal mass compensation capability like in Promash. I've also written several other calculators; IBU, Temp Conversion, Blood Alcohol Content, beer alcohol & calorie content, Priming, Infusion, & Decoction. They are on my club's website (URL in sig line) on the brewing tools page (this is the shameless plug). I don't claim any originality on these - mostly I was just practicing my Javascript skills and wrote these for anyone to use. Some were adapted from others I found on the web, some were originals, and some were adaptations of spreadsheets. Feel free to use them however you want. I would appreciate getting any feedback from folks who use these. It will be used to improve upon them. WARNING TO NETSCAPE USERS: I have not verified the operability of these calculators using Netscape. Even though I'm not a Microsoft fan, I figure that since IE has 85% of the market, why bother developing for multiple browsers, especially since IE is free and works better with code written to the W3C standards.

Hi Everyone, Last night I stopped by a pretty good [ probably excellent is the right word ] site related to Belgian Beer and home brewing. I guess I should not have been drinking that cup of coffee, because I did not bookmark. That will teach me to stray from my favorite beverage in the evening! After an hour of searching for that site this morning I don't have any more hair to pull out. So I am taking this last ditch measure of asking for directions...you know, it's a guy thing. Something about this site that may toggle someone's memory is that it has a pronunciation guide for various Belgian beer names, where a native speaker will pronounce the term as it is said in the US as well as it is said in Belgium. There was a lot of other interesting stuff there as well. I found this place very interesting! I want to go back! I can't find my way! HELP! In the mean time I guess I will go back to the basement and continue massaging my steam-injected RevRIMS... Thanks in advance... Bill Macher Pittsburgh, PA USA Return to table of contents

I think the secret is not heat setting but recirculation rate. I recirculate with a false bottom with the kettle valve wide open to allow a fairly high burner setting (but not roaring), and I get reasonable ramp speed. I guess between 1-2 degrees F/minute for a 7.75 gallon batch with 11-14 lbs grain. My recirculation liquor doesn't seem to get more than a few degrees hotter when measured at the output than the existing mash temperature. At this recirculation rate, the grain bed would set, so I stir it every few minutes. That means it's a cloudy recirc, but who cares? It clears at the end when I recirc slowly.

This is of interest to me not only in that the late hopping schedule is being challenged, but that it also challanges the following: What is the temperature range required for extraction? What is optimum as far as contact time vs. temperature? How is isomerization effected over these ranges? What about when you don't want isomerization to occur? How does the different levels of isomerization/non-isomerization achieved affect the flavor & aroma? I believe that most of these questions can only be answere right now in generalizations, not in concrete formulae. >Have any of the engineers out there done the math on these processes to >provide formulas? If not, now is your time to shine! (I can imagine some >simultaneous equations coming in here.) I don't think we have all of the formulas and data necessary to do a final calculation yet. Too many factors come into play and I don't think there has been a lot of research (published, at least) on hop chemistry to provide concrete answers. Humulone, cohumulone, myce*&%#$ at , frikin'-frakinak-arene, blah-blah-blah... All of them in different concentrations in different hop varieties, with different maximal values for different characteristics. Hop chemistry is a complex subject.

It isn't black malt, chocolate malt, or roasted barley since the same recipe also calls for those 3. Any ideas what this is? Who makes it?" Kevin, I am planning on trying some Kilncoffee Malt this weekend as a modification to my usual Oatmeal Stout recipe. I will be using 8oz in a 10 gallon batch. The malt has a mild coffee smell to it and is 165L to 175L in color. I don't know how this will differ from just adding coffee as I've not tried coffee flavoring before. The malt is produced by Malteries Franco - Belges. They call it Coloring 450 kilncoffee. One of our local shops, http://www.homebrewmart.com/ carries this malt, but it is not listed in their on-line catalog. If you give them a call, I bet they will sell you some.

Date: Fri, 2 Mar 2001 13:29:45 -0500 From: Jeff Renner <nerenner at umich.edu> Subject: Gelatin questions Brewers I've had several private email questions regarding bottle conditioning beer that has been fined with gelatin. These brewers were concerned that there wouldn't be enough yeast remaining to condition the beer. Even if you were very careful not to pick up any yeast with your racking cane when racking from the secondary to the bottling bucket, there would probably be enough yeast for a successful, albeit slow, bottle conditioning. Still, I always make sure to pick up a little extra by stirring up a little sedimented yeast with the tip of the cane. Even so, there is very little yeast on the bottom of the bottles this way. I like to say it's the thickness of a coat of pain. This has the advantage of allowing rather carefree pouring. Even if you don't decant the beer off the yeast when pouring, there is so little it makes little difference in all but the palest beers (like CAP).

I have had good luck several times with the Chimay. If you check the bottle cork before you purchase, you will notice it's dated. I have unsuccessfully attempted several times with a 6 month old dated bottle. The last several attempts have all been successful, it seems like a date 3.5 months old or less will work nicely. I am using a magnetic stirrer and flask with about 1/2 inch of Chimay settlement and liquid well shaken and poured into the flask. I flame the bottle top before pouring, and add about two ounces of new wort. With the stirrer, the next day I had activity. I was able to grow about 3/16 inch layer on bottom of a 500 ml flask in about 4 days with 2 refeedings. Without the stirrer, it still worked, but it took about a week before noticing any activity.

Date: Fri, 2 Mar 2001 22:45:55 -0600 From: "Richard Sieben" <sier1 at email.msn.com> Subject: CC fermentors, kilncoffee malt, and sorgum malt I have to agree with Steve Alexander on the cylidroconical fermenter debate, save your money. First off why do you want one? to harvest yeast primarily. Well the problem with the homebrew versions is that they lack proper cooling and temperature control in the cone portion, just where you are getting the yeast to sit. Being of narrower (is that a word?) width than the main part of the fermentor, it is more subject to room temperatures than the rest of the fermentor. The only version I have seen with a cooling jacket was 1) very pricey and 2) still had no cooling and seperate control for the cone portion. Just because it looks like what you see in breweries, doesn't make it so! If you want to dedicate walk in cooler space to a cylidroconical, that helps, but that is a very expensive way to chill a fermentor in my opinion. You could easily afford several small chest freezers and temperature controllers for the same price as one temperature controlled ccv on a homebrew scale. Don't mistake room temperature for fermentation temperature, you need a thermometer measuring the beer temperature to really know, at least with a glass carboy, you can use a stick on liquid crystal thermometer that is reasonably close and no chance of infection and they are cheap. About the valves on these homebrew ccv's, I don't like ball valves for anything on the cold side. I used to think they were the cat's meow until I learned that there is space between the valve housing and the ball that is a great breeding ground for beer spoiling organisms. You can mitigate this when you clean and sanitize by turning the valve on and off a lot of times while passing your cleaning and sanitizing solutions through them, but the technique is not perfect. On the other hand, I also recognize that most homebrewers don't even know when they DO have an infection, so would they really notice any difference? So what type of valve to use? there in lies the problem, ball valves are cheap and sanitary globe valves are expensive. To me the solution is to use a carboy and take a pass on the ball valve issue entirely. Kilncoffee malt is made by MFB and the closest to it on the North Country Malty Supply reference sheet is Briess 'Extra Special'malt. Finally, a question from me: does anyone know where you can get sorgum or even better, sorgum malt here in the US? I have been reading a bit about sorgum beers made in Africa and I wanted to try an experimental batch of it, just to see what it tastes like. I would even take a stab at malting my own, if I even knew where to get the grains. anyone? anyone? Bueler? Rich Sieben Island Lake, IL Return to table of contents
