---------------------------------------------------------------------- Date: Tue, 30 Nov 1999 13:06:05 +0000 From: AJ <ajdel at mindspring.com> Subject: Dilution Nathan Kanous suggests dilution as a means of iron remediation. Dilution is fine sometimes (I use it to get a good water profile for Pils for example) but sometimes it's not the best choice. As an example, one of the members of my club (BURP) asked me to look at his water. It was quite turbid coming out of the tap. Sure enough he had 1.2 mg/L Fe(III) and no measureable Fe(II). To get the level of iron down to the recommended 0.1 mg/L (less would be better as iron is pretty "tasty") he'd have to dilute 12:1 thus lowering his Ca and Mg by the same ratio.We might as well advise him to brew with distilled water and build up a mineral profile by salt addition. Too bad because the water was pretty nice otherwize (alkalinity 29, total hardness 26, RA 22, sulfate 0 - a candiate for even Boh Pils if the iron could be disposed of). In this partucular case pulling a test sample of the water through a 0.45u filter removed the iron to the point where the treated sample read 0.01 mg/L (close to the EDL for my gear). Thus his water is fixed by simple filtration with no chemicals or aeration. He's lucky and, of course, not everyone will be so. Others will require more dramatic treatment. So yes, dilution has its uses but science has its place in brewing too! - -- A. J. deLange Numquam in dubio, saepe in errore. Return to table of contents

It seems to work quite nicely for stainless steel and/or porcelain and pyrex. I believe it may have been originally marketed by Corning. There is also a product called "ZUD" which will remove rust stains from whatever. Tom Clark Return to table of contents
Date: Tue, 30 Nov 1999 07:38:54 -0600 From: Louis Bonham <lkbonham at hbd.org> Subject: More RIMS ideas . . . Hi folks: Bill Macher muses about using a counterflow chiller setup as the RIMS element . . . I've been working with a similar design for an improvement to my RIMS (I have the original BrewMagic prototype Conrad Keyes build years ago). My idea also borrows a few ideas from Micah Milspaw's RIMS system (Micah uses a quasi-HERMS system, with the coil in a sealed container of oil, and the electric heating element is used to heat the oil and keep it at a constant temp (about 175F if I recall correctly).) My concept uses the Heart's Superchiller (wonderfully efficient CF chiller) as the "heart" of the system, and a 2 gallon sealed reservior of oil as the heat-supplying fluid. The existing RIMS pump is used to run the wort through the exchanger, and a small hydraulic or similar pump handles the hot oil. Heat to the oil reservoir could be through an electric heating element (for maintaining target temps of the oil) and possibly also a gas flame (if needed). I envision that the oil would be kept at about 175F (fixed thermostat, with safety cutouts if the temp exceeds 220F, etc.). Temp control would be handled by controlling the oil pump (when heat is needed, the pump is on; when not, it's off; ideally, PID control to for pinpoint control without overshoots). On paper, this system would allow for very quick boosts without scorching. Comments? Louis K. Bonham Return to table of contents

Sometimes historical progress seems overrated, but in this case (and I guess I'd lump haggas (sp?), the entire phenomenon of boiled pudding, head cheese, et al. into the same category), I get warm fuzzy feelings about all of those biogenetic engineers plugging away in labs so that I can have strawberries in January. But then, there's no accounting for taste. One man's meat is another man's poison, and in the case of Cock Ale, it might just be both. Mike Return to table of contents

As a data point, Navy galleys (kitchens) are prohibited from using metal cleaning pads. The metal pads eventually break down and provide metal slivers that can get into food or be rinsed down drains that on ships have valves further downstream that can get scored or clogged. Home use is at the individual's risk. 3M's Scotch Brite pads with the appropriate cleaner work just as well (std. disclaimers) and don't wear out the pots.

The following is an all-grain recipe that comes pretty close to Tupper's. It is a little more fruity/estery due to the yeast and a little bit more hoppy (bitter, flavor, and aroma). hops-in-your-face IPA #5 Grains: 10 lb Crisp Maris Otter Pale Malt 2.75 lb Weyermann Munich Dark (11L) 4 oz Crisp Crystal Malt (60L) 8 oz Crisp Wheat Malt 4 oz DWC Aromatic Malt (26L) 6 oz M&F Carapils Malt (8L) total: 14 lb 2oz Mashed all the grains together in 20 quarts of water at 150F for 65 minutes. Raised temp to 168F for a 15 minute mashout rest. Sparged with 18 quarts of 170F water. Hops (all are whole flower hops): 0.25 oz Columbus 15.7%AA first wort hops 1 oz Columbus 15.7%AA 60 minute boil 0.5 oz Columbus 15.7%AA 40 minute boil 2 oz EKG 4.5%AA 10 minute boil 2 oz Cascades 6.0%AA 0 minute boil (steeped) 2 oz Cascades 6.0%AA dry hop 0.25 oz Columbus 15.7%AA dry hop total: 8 oz (approx 70 IBUs per Tinseth using 6.25 gal post-boil volume) Yeast: Wyeast #1968 (Special London Ale, supposedly the Fuller's ESB yeast) I pitched the entire yeast cake from the primary of a previous batch that was racked to the secondary on the day this IPA was brewed. Wort temp at pitching: 62F 3 hour lag time. Misc ingredients: 1 tsp gypsum (calcium sulfate) in the mash 1.5 tsp irish moss (rehydrated) added 15 minutes before the end of the boil Specs: brewed on 4/11/99 racked to secondary and added dry hops on 4/18/99 kegged on 5/10/99 primary ferment at 63 to 66F secondary ferment at 58F OG = 1.065 FG = 1.013 I've entered this brew in 2 competitions this year (NNERHC in ME and the Dixie Cup in TX) were it has consistantly scored right around 40 points. As you can see from the name, this is my 5th iteration on this recipe. This, and previous batches, were strongly influenced by the American IPA article that appeared in the Sep/Oct 1996 issue of BT. If you like big, hoppy IPA'a give this recipe a try and let me know what you think of it. Hoppy brewing, Jeff ========================================================================== Geoffrey A.

Date: Tue, 30 Nov 1999 09:54:57 -0600 From: Greg Remake <gremake at gsbalum.uchicago.edu> Subject: German Pilsener advice Hello all, There is a distinctive flavor in certain German pilseners that I'd like to achieve in my next recipe. I wish I was able to adequately describe the taste, which is not found in all German pilseners. It's a slightly spicey flavor, more prominent as an after-taste, although evident in the aroma. It is obviously there in commercial examples like Henninger and Herforder, but is missing in more popular brands like Haacker Pschor and Becks. Sorry for the lame description, but I'm hoping someone in The Collective will know what I'm talking about. I've never found this elusive flavor using a variety of noble hops, so I'm pretty sure it's not the hops. Perhaps it's the specific malts used, in which case I'd need to get a hold of the same variety, which may or may not be easy. I'm hoping it's the yeast. Pilsener Urquell is a favorite of mine, but that taste and style is not what I'm after, so I don't think the Czech/Bohemian yeasts will get me there. I'm familiar with Wyeast 2206 Bavarian, and that doesn't provide the flavor I'm seeking. I'm wondering if White Labs WLP830 German Lager might work, or perhaps another Wyeast offering. Any thoughts or suggestions? I'll also need some tips on mashing regimens. All help will be much appreciated. Cheers! Return to table of contents

Degermed is potentially better for the reason you mention, although George DePiro and Jack Schmidling both have reported no problem with whole corn meal. I'd certainly smell it for rancidity. Around here we have a bulk "old fashioned" corn meal that is coarser than the grocery store stuff. Coarser is better. Have you asked the merchant for information such as oil content? Maybe if you get the producer's name you can find out from them. Have fun brewing this great style.

I would pump the >water from the HLT as the heat source if I did this.... My present HERMS system uses the HLT as the heat source with a copper coil thrown in for the circulating wort. It works well, with room for a few improvements, one being the ability to quickly change the HLT temperature. This is not so easy because of the large volume needed for sparging. I am considering building a separate small volume chamber, say one gallon or so, into which the HERMS coil will reside. My 4500 watt electric heating element will be used to heat this water, which should respond rather briskly to the power applied. I will have a simple vent hole to allow the steam to escape, if any steam is generated. The whole project would be fairly easy to construct, another $10.00 heating element, a simple container, another copper coil, and a few electrical connections to the heating element. I will not be pumping the heated water, I trust that the agitation from the heating element and the low volume (one gallon or so) will supply all the needed thermal exchange. >It is difficult to control temperature of the re-circulating wort >just by varying the gas under the pressure cooker due to >delays in the system.

Hey all, Although I mostly lurk these days and post rather infrequently I do enjoy reading the HBD. It is that time of year again to get down on our hands an knees and kiss Pat Babcock and Karl Lutzen for doing such a fine job with this service. It has been hmmmmm 3 years... or is it 4 years that some nameless wanker talked Pat into taking on this digest and saving it from its certain death at the hands of the AHA. Pat was promised help by many and received it from few. Yet he and Karl continue to bust their bottoms to get this thing to us everyday. Probably much to the angered looks from their spouses. Pat has spent more time than he is willing to tell us working on servers along with Karl. Both have spent cash out of pocket to make the HBD work also.

It started rusting like crazy and when we went over the possibilities and discussed this with others, it seems that wire brushing and steel wool were the culprits.

[snip] >On paper, this system would allow for very quick boosts >without scorching. My concern would be getting enough heat into the wort when using a chiller designed for cooling while limiting the hot-side liquid temperature to 175 F. When cooling there is a pretty big temperature differential, worst case something like 212-90 = 122 degrees F., between the two liquids involved. Using a chiller that is designed to work with this kind of delta T, as a heater, in an oil bath that is at 175 F, where the delta T is probably 75 degrees max [and would approach 7 degrees at mash out] flags major concerns in my mind. My experience tells me that it would take longer and longer to get desired temperature boosts as wort temperature approached the hot-side liquid temperature of the heat exchanger. This is because in a RIMS we are limited to a maximum practical recirculation rate. The way I see it is the amount of heat that is pushed from the hot-side liquid into the liquid being heated is a function of the thermal resistance of the path between the two liquids and the temperature difference. In the case of a chiller, the thermal resistance is fixed by the design. The chiller is designed for a relatively large delta T between the two liquids that pass through it so the surface area can be relatively small. The variables of concern become the flow rate of the wort and the temperature difference between the wort and the oil, since the chiller proposed is one already manufactured and changing the surface area is not an option. At a given operating condition of the RIMS you will have a set temperature difference between the two liquids and a given flow rate. Say for example, the oil bath is at 175 F. and the Wort is at 120 F. As the wort is heated BTUs of heat will move from the oil bath through the copper wall of the heat exchanger into the wort. This transfer of BTUs will result in a temperature rise in the wort as it passes through the heat exchanger. Let's say this steady-state condition occurs at a flow rate of 2 gpm and that the wort is raised 10 degrees F. These may be attainable values across a heat exchanger designed for cooling. I doubt if you would get more and perhaps you would get less. If this were the case, temperature boost of 2 degree F. per minute for the mash would be achievable. I base this on the assumption that for a 10-gallon system there would be about 5 to 7 gallons of liquid being re-circulated, some heat losses in the system and also heat required to heat the grain bed. It would take 3 to 4 minutes to run all the liquid through the heat exchanger once. So the temp boost would be between 2 and 2.5 deg. F. per minute. [10 degree rise taken over 4 minutes.] Since the grains hold some water, perhaps only five gallons would actually be recirculated, but the other water held by the grain still needs heated so the effect is about the same I think. If you cannot get a high recirculation rate, things slow down quite a bit. But what happens when the wort temperature is 145 F.? Flow rate remains maxed out at 2 gpm to prevent filter bed compaction. The heat exchanger is a fixed element that offers essentially fixed thermal constraints. Delt T is now half what it was at 120 F. Only half the original BTUs will flow into the wort. We now can only get 1.25 deg. F. per minute rise in wort temperature. Splitting the difference again, at 157 F. we get a max temp rise of about 0.6 deg F per min. And so on.. This is a simplified look at the process and the intention is not to be terribly accurate in the calculation, but rather to convey a point. The point I am making is that it will take a very long time to get to mash out temperature of 168 F. if you keep the oil bath at 175 F. An alternative might perhaps be to heat the oil to a higher temperature and to maintain a constant delta T between the oil and wort temperatures. What matters is not what the temperature of the heating liquid is, but rather what the temperature of the heated wort is as it exits the heat exchanger. Having the ability to drain the hot side liquid out of the heat exchanger could also be advantageous. Turn off the hot-side pump, let the hot side liquid drain back to the source, and keep the wort recirculating at the temperature it is at. Of course, this would only work if the heat exchanger were physically located above the source of the hot side liquid. Or perhaps just turning off the hot-side pump and letting the wort pull whatever excess BTUs happen to be in the oil would be satisfactory. The volume of oil in the heat exchanger would not be that great. In the case of steam injection it is possible to cut the heat input almost immediately. I simply open a dump valve, which dumps the steam into my HLT, and close the valve that is in the line feeding the steam injection chamber. Bottom line is, I think, to be wary of using a counter flow chiller designed for cooling in a heating application where the delta T can be very small. This is especially true if one plans to keep the temperature of the hot-side liquid close to mash-out temperature. Isn't the gadget side of homebrewing fun!

I have compared prices from a number of different vendors for large brewpots. Most are the Polar Ware-type 10 gallon pots with a ball valve, and will run between $170-$200. I checked out the web page of Brewers Resource and found that they have 1.2 mm thick, 18-8 stainless steel brewpots that hold 13.25 gallons for an incredible low price of $166.90. They don't charge for shipping, so this seems like a great deal. I have never dealt with them before, so I'd like to know if anyone has ever had any bad experiences with them. If anyone has this brewpot, I'd love to hear if you'd stay with what you have or would you get the Polarware pot instead. Many thanks!

Date: Tue, 30 Nov 1999 19:17:25 -0800 From: Jack Straw <jstraw79 at pacbell.net> Subject: Legality of trading I have a question concerning the legality of trading homebrew via snail mail. You know, sometimes you can get chatty with other brewers on another coast, and I have been tempted to send them some of the latest batch, however, I dont know if that is legal. Also, what if that same conversation turns into a request for some beer that is not available on that coast (ie: east coasters asking for some SN Celebration). Does anyone know anything about this, or is it just something better kept underwraps? Thanks for your time gentlemen.

Date: Tue, 30 Nov 1999 22:40:45 -0500 From: "gdepiro" <gdepiro at mindspring.com> Subject: Oxidation of beer due to starters Hi all, Alan Meeker raises the question of the danger of beer oxidation when adding oxygenated wort to a fermented starter that is 10% of the total volume of the batch. This used to concern me, too. In my experience I have found that the beer made in such a way does not taste oxidized (even though the starter will often have noticeable diacetyl). A lot of this experience has come to me here at the brewpub, where the beers seldom last more than 3 weeks (because they are sold) and I have complete control over the beer storage environment. I don't know if the practice of adding oxygenated wort to a fermented starter would have an deleterious effect on the shelf life of the beer. My guess would be that it would. In further defense of this practice, it has been shown in journals and by some HBDers (AJ deLange, I think) that oxygen is very quickly consumed by healthy yeast. Given that the yeast in a recently fermented starter is about as vibrant as they get, they should consume the O2 in short order. I pitch my ale worts at a cool 58-60F (~15C), which might also help in reducing the oxidation of the starter. Since many homebrewers have good control over the environment that their beer is stored in (cold and dark), I would wager that no oxidation problems would be noticed when brewing with yeast propagated in the manner I described earlier. As a homebrewer (and pro) I am more concerned with O2 pick up in the finished beer. Homebrew transfers present a plethora of opportunities to unwittingly oxidize your beer (racking into carboys being a big one). It is probably more worth while to put effort into keeping O2 out of the finished beer than to worry about the starter becoming oxidized. Letting the yeast settle out, as Alan suggests (and I used to do at home) has several disadvantages: 1. It takes a long time, during which yeast viability may decrease. 2. You are throwing away the least flocculent yeast when you decant off the fermented starter. If you do this at each step up you may end up with a yeast culture that floccs too early (I can't remember the reference for this; I think it's mentioned in an old HBD or my BT article on yeast). 3. You are throwing away yeast by decanting off the liquid from the starter (this seems cruel to the yeast and is wasteful). Alan's suggestion of using a centrifuge to separate the yeast from the beer is a good one, if you have a centrifuge! One thing that you should be aware of: the starter should not be too different in hop character from the main batch. If the hop rate is substantially different, be sure to compensate for that fact when you brew the main batch (adjusting the hops up or down accordingly). Have fun!

Date: Tue, 30 Nov 1999 21:57:32 -0600 From: "Sean Richens" <srichens at sprint.ca> Subject: stainless and non-stainless scrubbies David Sweeny has heard correctly - stainless steel can be fairly seriously compromised by contamination with regular steel from Brillo pads, or by sharing grinding wheels or wire wheels with non-stainless steel items. But really, unless you're grinding & polishing welds, you just don't really want to use anything more abrasive than a WHITE Scotchbrite pad (green is harsher) or standard nylon pot scrubber. They all leave scratches which just makes cleaning less effective the next time. If it's badly soiled, try alternating alkali and acid soaks, or try laundry detergent, or electric dishwasher detergent. They all have different modes of action - use any of them at 60*C (145*F or so) for maximum effect. Return to table of contents
Date: Tue, 30 Nov 1999 22:56:01 -0500 From: "Karp's Homebrew Shop" <alant at homebrewshop.com> Subject: homebrew event, Jack Schmidling, etc Just had to post a summary of an interesting brewery/homebrewing event. I think that brewing clubs around the country might want to try a similar event. The Black Forest Brew House, in concert with the Brewers East End Revival (B.E.E.R.), held a brewfest on the brewpub's grounds. The members of B.E.E.R. were invited to bring their homebrewing equipment, propane cookers and all, to the brewpub. The homebrewers setup on the patio, and made a batch of beer using their own equipment, right at the brewery. The pro brewer, Michael Hoeck, was present most of the day to help with grinding grain and dispensing advice. The brewpub served up a special complimentary brunch, and served pints of lagers for a special price. For brunch time entertainment, the club showed a video of the Emeril show featuring (the outstanding) brewer Garrett Oliver. It was fun to see how little Emeril knows about beer. Lots of great smelling wort was made, some all grain and some extract. It especially fun to mash in with heated, filtered water- directly from the brewer's hose, and hit protein rest temperature right on the head! As a veteran of many homebrewing events and contests, I must say that this was as much fun as any brewing event I've ever attended. I highly recommend other brew clubs seek out friendly brewpubs to hold similar events. On another subject entirely, let's talk about wine kits and Jack Schmidling's idea that wine kits are pretty bad overall. (It seems the only way to convince Jack that the newer juice kits make pretty good wine is to send a bottle of good stuff to him.) The discussion left out an important new development in the home wine market. You can now get non-concentrated wine juice to make wine from. Since Jack is such a giving guy himself, I plan on sending him a bottle of the Merlot I just bottled. Maybe he'll like it and change his mind. And maybe not. Either way, it's a brilliant plan on Jack's part to get winemakers from all over to send him a bottle of good wine. I applaud him and wish I had thought of that challenge first!
