---------------------------------------------------------------------- Date: 6 Mar 93 10:09:00 +1000 From: BELLAGIO_DAVID at Tandem.COM Subject: RE: Boiling Water on Electric Burner Joe Thomas wonders about boiling water on an electric stove. I have an electric stove that I use for my brewing and have learned some lessons. The first lesson is that if you are doing a full 5-6 gallon boil it takes a long time to boil ( about 40 minutes ). The second lesson is that if you do a full boil for an hour, your element will last about 3 batches before becoming extremely warped ( thus decreasing contact surface and increasing boiling time and heat directed elsewhere ). This warped element eventually leads to a melted connector ( this actually happens after batch #7 since I was alternating between both my big burners ). So, then I went to the appliance part store and had to by a connector plug, two reflector shields, a regular large burner, and an extra heavy duty canning burner. The canning burner cost $35.00 and I highly recommend it! It has extra support and is raised higher than the stove top. It also has a higher heat output. Now, I boil my wort and don't have to worry about the heat and weight warping my burner. I would think a way to decrease the boiling time would be to start boiling a gallon of water on both burners, once they are close to boiling, put one in the other and refill the empty one with a gallon and bring it to near boil. Keep doing this until you have the desired amount in your big boiling kettle and it should all be near boiling then. I have not done this since I am lazy. Have fun.

I asked HBD readers who had experience using brown sugar to write with me. The results are mixed but generally positive. In HBD1090, Russ Gelinas said: > Re. brown sugar: In my book, it's virtually *required* in an English >style ale. Yes, I actually add brown sugar to all-grain batches, usually >1 lb (10-15%).

Just a heavy molasses-ey flavor. Donald O'Connor suggests Belgian Special B. I'm going to give that a try. A good solution for the purists, too.

Date: Sat, 6 Mar 93 19:02:29 -0500 From: bradley at adx.adelphi.edu (Rob Bradley) Subject: demerara & turbinado "Turbinado" and "Demerara" are the "real" brown sugars. They are both partially refined cane sugars. I've heard it said that they are, respectively, the American and British names for the same thing. However, turbinado is _very_ pale, lighter than a brown paper bag. Demerara is about as dark as a brown beer bottle. Demerara is readily available in the UK. Can UK readers confirm whether turbinado is the same thing called "Trinidad" sugar by Dave Line? As Jeff Frane said, turbinado is available in North America in health food stores. When I lived in Toronto, I could buy demerara, imported from the UK, in homebrew shops. My respondent #2 tells me it can be bought from Great Fermentations in Santa Rosa, CA, but in the form of sugar cubes!!!!! North American supermarket brown sugars are refined cane sugar with molasses added. (HBDers must be getting sick of hearing this: I said it in HBD1089. Arf repeated it in 1090, as though it was news. In 1091 Jeff Frane said "Jack is right". Is it a fact yet?) Some questions: since molasses is a by-product of the refining process, what's the difference between a solution of turbinado and a solution of refined white sugar with the appropriate amount of molasses? Could a chemist tell the difference? Could a yeast cell? Are there nasty trace chemicals in the supermarket brown sugar because of the refining process? Did respondent #2's H2S smell arise because his brown sugar was doctored with sulfurized molasses? Cheers, Rob (bradley at adx.adelphi.edu) Return to table of contents
Date: Sat, 6 Mar 93 19:46:10 MST From: pyle at intellistor.com (Norm Pyle) Subject: Older, but not sweeter / Cloudy I seem to have two problems with my homebrews, which I will discuss separately. The first problem I've had from my very first brews. It involves sweetness, or a lack thereof. As my beers age, they seem to lose the sweetness they had when they were younger. I'm comparing the flavor profile from a 1-month old brew to a 3-month old brew (since bottling). This has happened with extract brews, partial mashes, and all-grain'ers. I _really_ like my beers when they are young, but as they age, I like them less and less. The hop bitterness starts to overpower them, as the sweetness fades. Others have reported hoppiness fading with time, but with this problem, it seems to gain prominence. Anyway, I suspect the hop-fade reports really refer to aroma, less so than bittering. So, this sounds like an infection problem, right? Bacteria/wild yeasts eating up the "unfermentables", etc. etc. Well, none of my brews have ever experienced gushing. The worst its ever gotten is some bottles having more carbonation than others, which I attributed to poor mixing of the priming sugar (this hasn't happened in quite a while). Of late, I can't discern a difference in carbonation between the "young" beer and the "old" beer. Of course, comparing a 3-month old beer to the memory of a 1-month old beer is difficult at best. Help? Comments? I'll discuss my sanitation procedures in another post if that seems to be the tack to take. Second problem: my all-grain brews (3 to date) are, without exception, cloudy. I do a simple single-stage infusion at 150-158F. I've used American and British 2-row. I try to do a mash-out, but I know the temperature isn't 165F+ like it should be (I don't think mash-out would have anything to do with this anyway). Do I need to a protein rest? At what temp? I mash in a cooler, so upward infusion is doable, but I'd only like to do it if necessary. BTW, the cloudiness doesn't make them any less tasty, but a friend says he likes all-grain because he can get his beers much clearer than with extracts (probably among other reasons as well). What gives? Thanks for your (collective) advice. It will be appreciated. Cheers, Norm Return to table of contents

Date: Sun, 7 Mar 93 23:09:12 -0600 From: hpfcla.fc.hp.com!melkor!rick (Rick Larson) Subject: Alan's RIMS Implementation, Part 1 Here is part 1 of some text I received from Alan Gerhardt about his RIMS implementation. - ---------Alan's-Text---------- Hi Rick, I built my mash tun by getting a 15.5 gal keg, using a metal cutting blade in a circular saw to cut the top off at the top seam where the handle ring is welded on. As it turns out, the groove at that weld tends to guide the blade, so it is easy to get a straight cut. Be sure and use safety glasses, however, because sparks and metal bits will be flying. Make sure you follow all the normal safety tips for working with kegs as well. I then drilled a drain hole in the bottom, and used a brass "cooler drain" fitting. The fitting has a nut and a gasket, which gives a good seal, and is threaded on the inside as well. I then attached the required pipe/fittings to connect the drain to my RIMS unit. ======= =======flange =| |=gasket ----------| |------------keg bottom ======= ======= nut || || | | | |other fittings to suit I used a water heater jacket as insulation by cutting it in approx thirds, and wrapping three layers around the keg and securing it with duct tape. For a false bottom, used a piece of 3/8" copper tubing formed in a circle to fit the bottom of the keg, and soldered a straight piece as an extra support across the center. Picture an international "NO xxx" symbol and thats what it looks like. A piece of stainless screen rests on top. I also soldered a 1/2" copper coupling to one side of the inside of the copper ring into which I stick a vertical piece of copper tube as a vent stack which sticks above the grain bed. This limits the compaction of the grain bed by the suction from the RIMS pump. If you're not using a RIMS, then you don't need the vent stack, and you have a conventional mash/lauter tun.

Date: Sun, 7 Mar 93 23:11:08 -0600 From: hpfcla.fc.hp.com!melkor!rick (Rick Larson) Subject: Alan's RIMS Implementation, Part 2 Below is the remaining text I received from Alan. - -------- Date: Thu, 23 Jan 92 14:57:32 -0600 From: agerhardt at ttsi.lonestar.org (Alan Gerhardt) Subject: RIMS Part 2 As promised, here's a description of my RIMS unit. I started with the R. Morris basic design and adapted it as needed. I think Rodney deserves a lot of credit for coming up a practical homebrewer's implementation of this idea. His methods sure gave me a headstart. I wanted the unit to be able to do at least a 10 gal batch size, which for me usually equates to 16-20 lbs of grain, so I chose a 5KW heating element from WW Grainger. It is a very low heat density element which is advertised to be able to even run dry. It is a very long element, which has in a "U" shape, and folded over to be about 19" long. It cost about $20, but has turned out to be a very good investment, in that I have seen no evidence of excessive heating (which would kill the enzymes) or scorching. With this element, I get about 1.75-2 degrees/min temperature boost with 18 lbs of grain and about 7-8 gal of water. I used a length of 1.5" (about 21") copper pipe as an element housing, with a cap for each end, and assorted fittings to connect things up. I used a length of 1.5" (about 21") copper pipe as an element housing, with a cap for each end, and assorted fittings to connect things up. outlet------------------------------------------------- .5" copper pipe ----------------------------------------------- | | | ---- | | ----__ | ------------------------------------- --- | |-_ | |==========================================| | |- | |==========================================| | _|- | ---- ------------------------------------- |__|- ^ ---- | | ---- ^ | | --- __ | element | |||||__ stopper with | head | --- thermistor | | | | ------ copper nut | |-------------- | | | inlet------------| | | ------------| | pump | | | | | |-------------- ------ The inlet and outlet pipes are .5" copper. I drilled holes in the 1.5" tube for the inlet and outlets ( a tight fit is better ), and soldered them in. The trickiest part was the mounting of the heating element. Rodney used a 1" threaded pipe to copper pipe adaptor. Since the adaptor narrows down too much to allow the element I chose to fit through, I cut off the threaded portion, in effect making a copper nut. I soldered the nut outside of the cap ( with hole drilled in it ), and the element just screws into the end of the pipe. The supplied gasket makes a water tight seal. The element is easily removed for inspection/cleaning, although cleaning is seldom required if a clean water rinse and recirculation is performed after use. I put the thermistor inside of a .125" copper tube, and sealed it in epoxy, being careful not to short it out. The tube is inserted through the stopper so that it sticks into the fluid flow. The Radio Shack thermometer Rodney used is no longer available, so I didn't put that through the stopper too. I use an external digital thermometer instead. I put the whole thing into a wood case, with the inlet and outlet tubes sticking out through drilled holes. I connect to the unit using plastic tubing and band clamps. I built a pump speed control per Rodney's design and it works fine. I have not been able to get his temperature controller to work yet, and am currently using a toggle switch instead. As he recommended, I used a GFI outlet inside my box, from which I get all power. That is in my opinion, a very wise investment. I set the whole system up on two Workmates, one for the RIMS unit, and the other for the mash tun. The whole thing disassembles and stores so I have my garage back when done. Observations: (1) At full flow, the outlet stream will sometimes generate a LOT of foam in the mash tun if not properly directed. (2) Sparging is a snap now. I just add as much water as my mash tun will hold, raise to 165-170 degrees, and recirculate for about 30 minutes. My efficiency is typically 30-31/lb/gal, for 6 row malt ( Stew's Brew malt ), just short of Miller's numbers. For larger quantities of malt ( not as much room for more water ), I plan to drain/replace the sparge water as required. (3) A proper grain grind is just as important as always. (4) The wort runs incredibly clear by the time you are sparging, and no husks or other particles make it into the boiling kettle. (5) If you are contemplating building a RIMS, don't scrimp on the pump or the heating element. (6) You have to be crazy or an obsessive tinkerer to go to this much trouble. I hope this helps somebody !

I added it in the hopes of improving body without increasing color, but I tasted the powder prior to addition, and it had very little taste. As such, you might give it a try to increase body w/o sweetness. I'm also interested in cara-pils malt. Could someone post a nano-tutorial on its use? From reading, I thought I could treat cara-pils as a very low color replacement for crystal malt, just steep it in my brew water while heating to a boil, then filter off before adding my extract. However, the guy at my local brew store told me that it needs to be mashed to allow conversion. I don't want to let enzymes chew the nice dextrins down too much, since the whole point is to get some viscosity. What's the story? Dave Whitman Return to table of contents

Date: Mon, 8 Mar 93 9:42:14 CST From: tony at spss.com (Tony Babinec) Subject: some comments on sugar HBD is in one of its cyclical sugar threads. Here are a few thoughts on sugars. Sugars such as American cane sugar (American table sugar) are highly refined sugars that, from the standpoint of brewing and your yeast, are fully fermentable. Molasses is a thick syrup produced when sugar is refined. American light brown sugar and dark brown sugar are highly refined sugar with some of the molasses added back in. From this, it does not follow that you cannot or should not use them in your brewing. As I understand it, brown sugar has some unfermentables that will impart flavor to the finished beer. Demerara sugar is a light-colored, partially refined sugar. Did you know that there is a Demerara River in Guyana? This must have been (still is?) a sugar-producing area. Turbinado sugar is a less-refined, darker, sticky sugar. You might be able to find these in health food stores. "Sugar in the Raw" is a light amber fine-crystal sugar available in commercial supermarkets (in the Chicago area, anyway) in 2-pound boxes. "Raw Hawaiian Sugar" is an amberish rock-candy sugar available in 2-pound bags. If you cannot find demerara or turbinado sugar, permit me to suggest that in recipes calling for demerara sugar, use Sugar in the Raw or Raw Hawaiian Sugar if you can find them, or use light brown sugar, and that in recipes calling for turbinado sugar use dark brown sugar. Molasses is available in at least two forms -- as mild molasses or as a stronger blackstrap molasses. I've avoided the blackstrap molasses but have used mild molasses in a few recipes. I didn't have a good idea how much to add, but I started with small additions on the order of 1/4 - 1/2 cup, as I didn't want the flavor to dominate. Finally, Rajotte's "Belgian Ales" suggests that Belgian brewers use sugar for coloring. The grain bills of Rajotte's homebrew recipes typically feature only small amounts of crystal malt or highly roasted malts, if any. Instead, he suggests that for pale beers use pilsner malt and refined sugar (or consider a light honey such as clover honey or alfalfa honey), and for color use small amounts of crystal malt or brown malt and use darker candi sugar. I think it's a great suggestion, though I don't know how to calculate the color contribution of darker sugars to the finished beer! Return to table of contents

For those interested, the day was great, and so was the ride. A bit of fog while crossing the Golden Gate, but this also was an indicator of the wind's minimal presence. Across in Marin, the fog evaporated and was not seen until we crossed the Bay via ferry that evening. The route is pretty straightforward ... down to Sausalito, along the bike path, under 101, across Blithedale in Mill Valley, right at the school, then along Lomita to 101, right, onto the bike path paralleling 101, over the hill and down into Corte Madera. Cross at the light, onto Madera, which becomes Tamal Vista. Go to the end, turn right, cross the freeway at the pedestrian bridge, then continue along, parallel to 101, back onto the bike path, along 101, down the off ramp, bearing right with the road, into the parking complex of the Larkspur Golden Gate ferry landing. It all sounds very complex but the secret is that everyone uses this path all of the time and it is well established, as well as quite intuitive. In every case but one - at the school, where the right turn is unobtrusive - choices were either obvious, IE, straight ahead, or intuitive, IE, in order to cross the freeway I needed to zig-zag a bit but the goal was obvious. We checked the schedule, then crossed the pedestrian bridge to the shopping complex Marin Brewery was within. We sat outside, on the patio, at a small table. ( There were only three of us - both, friends, neither HBD readers but both interested in brewing. ) The beer was good, but it was not noteworthy ... although my tiredness may have had something to do with this perception. The food, also, was good but not noteworthy, and the fish & chips, a touch oily. However, the clam chowder was excellent, and next time I'll have a bowl of that and skip the fish & chips. Their hamburgers may be much better, I'll have to see another time. Afterwards, we returned to the ferry building and boarded ... returning, we put two bikes in my truck and drove up to meet the third person, at the Toro- -nado ... thence, homeward. Overall, one of the best benefits of this ride is seeing just how easy it is to cover 20-plus miles in under two hours. ( We did it in 2:08 and loafed a _lot_. ) Another thirty minutes of riding and I could have been up in San Rafael, picking up brewing supplies at Great Fermentations ... and, of course, there are many other nice rides in Marin, as well as some nice picnic spots we passed en route. Although the brewery was not as rewarding as I thought it should be, the ride amply compensated for this lack ... and I _will_ return to the brewery again. One problem is the meeting place - where we met was not immediately obvious, although it _is_ the southmost end of the _bridge_, and it _is_ on the west side, and it _is_ the beginning of the bike path, as clearly denoted by the very large sign at the beginning of the crossing, which directs bike riders to go down the ramp and under the bridge, to the other side ... I hope this did not cause anyone any inconvenience. - -- richard "It is obligatory, within the limits of capability, to commend the good and forbid evil." _Kitab_Adab_al-Muridin_, by Suhrawardi richard childers pascal at netcom.com Return to table of contents
Date: Mon, 8 Mar 93 12:39:30 EST From: Ulick Stafford <ulick at bernini.helios.nd.edu> Subject: Infusion mash Stout I intend to make a stout using a single infusion mash with the major component of the grain bill being a British Pale Ale malt. But I want to know if I should worry about the fact that my roast and flaked barley have not been exposed to a prtotein rest - usually I make stout using lager malt with a prtoein rest, quite successfully. Is the likely problem a stuck sparge or simply poor conversion of the adjuncts? __________________________________________________________________________ 'Heineken!?! ...

The Vollrath pot has a SS tooled screen in the bottom. Upon applying heat, the temperature of the water/grain-dust solution below the screen increases rapidly. By the time I could thoroughly stir the mash, the temperature was at 190oF. Oops! Welcome to the ranks of us drones who have blindly built the "standard" version of the scaled down commercial mash tun only to find it poorly suited for home brewing. The following is the relevant section from my soon to be published article on Kettle Mashing..... .............. The key to the system is the screening device and the spigot for the kettle. The first one I made was to be used in conjunction with an overlaying false bottom. The false bottom was a stainless steel plate the size of the kettle bottom with a zillion holes laboriously punched into it. It created no end of problems on the very first batch. Mash got under it and scorching was just about impossible to control. So in disgust, I pulled it out, continued the mash and assumed a disaster was at hand. Much to my incredulous delight, when I opened the spigot, the wort ran clear after less than a cup of turbid runoff. I have since made about 50 batches using only the screen device and get very consistent and respectable extract yields. ..............

Probably just telling the truth and not fudging the numers :) We have been through this a zillion times and my opinion is that instrumentation error and measurement technique can easily account for +/- 5 points of uncertainty. 28 is well within the range of nominal. On my last batch I got 33 and the only thing I changed from the previous batch (30) was the malt. The most important thing is that, once you are in the ballpark, with what is expected, you should worry less about what others get and more about establishing a meaningful measurement technique that will give you consistant and meaningful results. If you change a process or ingredient, you want to know that any change in yield results from that and not from sloppy measuring. It is perfectly legitimate for example, to include the liquid in the trub you throw out in your volume determination but you must keep this in mind when you compare results with others and you must do it all the time. The same applies to reading the hydrometer. If you fudge to the top of the meniscus or the bottom, you must do it consistantly and keep in mind that it has about a 4 point effect on the bottom line when comparing with others. js Return to table of contents
Date: Mon, 8 Mar 1993 09:48:15 -0700 From: Michael Howe <howe at gwl.com> Subject: Celis Beers Hello all, All this talk of the various Celis beers arriving in cities around the nation has gotten me excited. My brother sent me an article from the Austin daily newspaper about Celis a while back. The article stated that Celis was going to be introduced in a number of test markets around the nation. COLORADO was one of the lucky states. I live and work in the Denver,CO area (Englewood to be specific) and have yet to see Celis anywhere here (believe me, I've looked). Has anyone in this area seen Celis at any of their local liquor stores? If so, could you please show me to the promised land :-). Any help would be greatly appreciated. I am getting tired of trying to EXPLAIN Celis White to people. I'd rather just give them a bottle of it... Reply via e-mail if you prefer.

Punch a hole in the cap for the fermentation lock, and I think it would make one hell of a closed fermenter. They cost about $23. Anyone use these before, and if so, how did it work?

The Hot Water heater element trick is sooooo cool (really!) and I like the responsible nature of the poster....but hey, we're adults (well most of the time) and if you whoever said Home Brewing wasn't risky business!!! On another note, during my travels in Mexico, I learned that at least one culture on the continent has a name for USAers and Canadians that relates to the land mass....most Mexicans call USAers North Americans... I throughly enjoyed the humorous posting about the Clear Beer Catagories....sorta reminds me of of Old Frothingslosh...point of order... Coors tested a product named "Zima" last summer. If Miller is using "Zima" as a product name, all of you weaselly lawyer-types might want to take time out from you "Boston"tm adventures to get on this fat cow. Oooooooh doesn't it make your nipples hard to think of yourself in the middle of a spat between these two well funded cowboys???? Well, back to work...and keep those fun science projects coming!!!!!

Date: 08 Mar 1993 14:05:42 -0500 (EST) From: Frank Tutzauer <COMFRANK at ubvmsb.cc.buffalo.edu> Subject: questions from a new snob :') Well, I finally did it. Yesterday I brewed my very first all-grain batch. Back in December I asked for some tips and got them, so a very belated thanks to Jay Hersh and Tim Norris (lauter tun designs), Rob Thomas (strike heat/mash temp formula), Jeff Benjamin and Spencer Thomas (general all-round advice), and Jack (quick delivery of a MALTMILL--for the record, mine had no debris and only a very light coating of oil which I took care of with a toothbrush and some really crummy roasted barley I had laying around). Some observations and questions: First, things went pretty well. Temperature control in my picnic cooler was harder than I expected and sparging was easier than I expected. I got about 28 points a pound. The runoff cleared *very* quickly, like within a quart or two. (I suspect Jack's mill is the reason why.) And about this business of the iodine showing conversion at the top of the cooler but not with the wort from the spigot: I didn't experience this phenomenon. At the beginning of the mash, both top and bottom turned black; at the end of the mash, neither did. So, who knows.... In terms of time, I would say that I only spent about 2 hours longer than my extract batches, and much of that was due to fumbling on my part since I don't have my technique down yet. Naturally, it took me longer to crush the malt than the pound or so of specialty grains I was used to using, but the sparge took place while the rest of the runoff was heating up on the stove, so that didn't really add much extra time (I've been doing full-volume boils). As far as I could see, only the hour or so mash represented any significant time over and above an extract batch. Now the questions. First, in yesterday's digest, Joe Stone asks how long the sparge should take. I've got the same question. Miller, people in my club, and lots of other folks talk about the sparge slowing to a trickle. Mine didn't. It did slow a little, but never to a trickle. If I'd've wanted to, I could have run it out like gangbusters. Again, my guess is that Jack's mill is why, and for me the length of the sparge seems to be strictly under my control. So, how long should I make it? The most convenient is to finish the sparge right as the wort on the stove is coming to a boil. Is this reasonable? Is longer better (more sugars?), or is shorter better (fewer tannins?)? Second, what's the deal on acidifying the mash? Miller says to get the pH to 5.0 to 5.5. I checked right after doughing in, and it was like maybe 6.3. I thought to myself, "Man, this is my first all-grain batch. I've got a lot more important stuff to worry about than acidifying the mash." Also, I remembered Miller saying something about not fighting the "natural inclinations of the malt." So I remembered not to worry, decided to let the malt naturally inclinate, and opened the day's first homebrew. What should I do in the future? Finally, should I acidify the sparge water? Charlie P.'s silent on the matter, Miller says to acidify to a pH of 5.7, and Noonan spouts of a typically let's-make-it-harder-than-it-needs-to-be Noonanism, something like acidify if the pH rises .7 during sparge but never more than .2 unless the azimuth of the moon corresponds to the declination of blah, blah, blah.... What should I do and how important is it? Thanks a bunch, folks, - --frank Return to table of contents
