Michael asked for some explanation on batch sparging technique, so I am copying this excerpt from my book here. Accordingly, I need to note that this excerpt is from How To Brew, 2nd Edition, Defenestrative Publishing Co, 2001 and that I am maintaining my copyright. Since I don't have the rest of the text from Chapter 18 here, I want to note that the equations shown below for batch (and no-sparge) brewing were developed by Ken Schwartz and that he has a writeup and a spreadsheet available at his site: http://home.elp.rr.com/brewbeer/files/nbsparge.html (from pages 220-222 of How To Brew) For example, here is a comparison of the standard 5 gallon recipe (continuous sparging) and the batch sparge and no-sparge recipes for the Tittabawassee Brown Ale you brewed for your first all-grain batch: Grainbill Standard Batch No-sparge pale ale malt 7 lbs. 7.6 lbs. 8.5 lbs. crystal 60 malt 1 lbs. 1.1 lbs. 1.25 lbs. chocolate malt .25 lbs. .3 lbs. .5 lbs. Total weight 8.25 lbs 9.0 lbs. 10.25 lbs. Total mash volume 3.75 gal 4.9 gal. 8 gal. Each method produces the same 6 gallons of 1.041 wort. The obvious difference is the size of the mash: 4.9 for batch sparge and 8 gallons for no-sparge, versus 3.75 gallons for the continuous sparge. You will probably need a bigger mash tun for these methods. Batch Sparge Recipe Calculations: Batch sparging works best when two sparge volumes of the same size are combined to create the wort. To keep the process simple, we want the first sparge volume to be what we get when we simply drain the mash. To do this, we need to calculate the optimum mash ratio that will give us that volume, including the water that will be absorbed by the grain. Then the batch sparge brewing process becomes as easy as conducting the mash, draining the first runnings to the boiling kettle, adding an equal volume of sparge water back to the mash, draining again, and boiling! First, let's define the terms in the equations: Inputs: OG: Standard recipe original gravity (just the points part i.e. 1.049). Gr: Standard recipe grainbill (total pounds). Vr: Standard recipe batch size (e.g., 5 gallons). Vb: Standard recipe boil volume (e.g., 6 gallons). Calculation Coefficients: k: Water-retention coefficient (0.5 quart per pound) Outputs: W: Batch sparge water volume (quarts). Rb: Batch sparge mash ratio (quarts/lb.). S: Scale-up factor for grainbill. Gb: Batch sparge grainbill (total pounds). Vm: Volume of water for the mash (quarts). BG: Boil gravity (points). BG1: Gravity of the first runnings (points). BG2: Gravity of the second runnings (points). Vt: Total volume of the mash (quarts). 1. Decide how many gallons of wort you will boil to achieve your recipe volume and thus your sparge volume (e.g. Vb = 6 gallons). W = Vb/2 (3 gallons i.e., 12 quarts) 2. Calculate the optimum batch sparge mash ratio. Rb = (Vb + (Vb^2 + 2k*Vb*Gr)^.5)/Gr (1.85 qts/lb.) = (6 + (36 + 1*6*8.25)^.5)/8.25 = 1.848 3. Calculate the scale-up factor. S = 1/(1 - k^2/Rb^2) (1.08) 4. Calculate the batch sparge grainbill. Gb = S*Gr (8.9 or ~9.0 lbs.) 5. Calculate the volume of water for the mash. Vm = Rb*Gb = W + k*Gb (16.6 quarts) 6. Calculate the gravity of the first runnings. BG1 = 4*S*Vr*OG/Vm (1.064) 7. Calculate the gravity of the second runnings. BG2 = 4*Vr*OG*(k/Rb)*(1 - (k/Rb))/(Gr*(Rb - k)) (1.017) 8. Verify the combined boil gravity and recipe gravity. BG = (BG1 + BG2)/2 and OG = BG*Vb/Vr (1.040 and 1.049) 9. Calculate the total batch sparge mash volume (quarts). The volume of 1 pound of dry grain, when mashed at 1 quart per pound, has a volume of 42 fluid ounces (1.3125 quarts or .328 gallons). Higher ratios only add the additional water volume. Vt = Gb(1.3125 + (Rb - 1)) (19.5 qts. i.e., 4.9 gallons) John Palmer john at howtobrew.com www.realbeer.com/jjpalmer www.howtobrew.com - the free online book of homebrewing Return to table of contents
Date: Fri, 14 Mar 2003 08:43:03 -0500 From: "John Misrahi" <lmoukhin at sprint.ca> Subject: re. White Labs Pitchable Yeast Claims I have seen all of the bickering over 'pitchable' yeast lately. People have complained that White Labs supposedly states their yeast is pitchable for any 5 gallon batch, without a starter, and that they are misleading people. However, I have a pamphlet caled "White Labs Beginning Yeast Basics" which states, "If more than a pint starter is desired for pitching (for beers over 1.070 Original Gravity, COLD FERMENTED LAGERS, or homebrewers wanting a faster fermentation), a 1-2 liter starter can be made in just one day". So they don't claim you can cold pitch a tube into 5 gallons of fermentation temp lager..... I just thought someone should point this out. I'm a happy White Labs and Wyeast customer. I use dry yeast too when it strikes my fancy ;-p John Misrahi Montreal, Canada [892, 63] Apparent Rennerian (km) "Actually John it uses a very complex algorithm to determine your average time between "Generate" clicks, and from that can it figures out how drunk you are, and what styles of beer you prefer.

I must respectfully report the opposite. I tried it once. That was enough. My attempt resulted in a green, grassy-tasting (and somewhat bitter) water. My tap water has a fairly high pH (8 - 9). Without some acidification, all sorts of nasty tannins and other flavors are extracted from the hops along with the desired bitterness. A bit of malt extract brings the pH down to a more reasonable number and prevents this problem. =Spencer in Ann Arbor, MI Return to table of contents
Date: Fri, 14 Mar 2003 11:17:12 -0600 From: "Franklin, Victor E" <Victor.E.Franklin at bankofamerica.com> Subject: Thoughts on peppers Although this is a little tardy I feel compelled to chime in on this. A couple of years ago I made a pepper beer my friends still talk about on occasion. They absolutely loved it. The beer was a very simple amber recipe that I added the jalapenos to. I have had pepper beers before that had an overpowering pepper flavor or nose to them. The beers seemed to be more pepper than beer. I wanted to avoid this. My objective was to avoid damaging the good beer flavor, like over-hopping a beer would. So in my thoughts I likened hopping addition times and the effects on the flavor, the nose impact this has, and jalapeno additions. Why wouldn't jalapeno additions be the same? I am sure the process is different but I couldn't find anything in the HBD about it at the time. I think the process worked. (Although I can't be sure as I didn't put any jalapenos in another batch in the fermentor) The beer seemed to have a low pepper-nose to it with a warm back-end. If I drank 3 of them it would start getting warm. Here is what I did: I used 6 small jalapenos cut in half and cleaned. I then browned them on a skilled (I like to eat 'em like this raw sometimes) and dropped them in the boil... for 50 minutes. Has anyone had experience with adding jalapenos to the begging of a boil on one batch and to the fermentor on another? If so, was there any difference between the two? If this were true it would be a great way to balance the heat vs. nose effect. In the end I would always suggest being conservative on jalapeno additions. I figure it is easier to add more later than to try and take some of the heat/ smell out. Victor Franklin Phoenix, AZ Already in the 80's :-) Return to table of contents
Date: Fri, 14 Mar 2003 09:35:54 -0800 From: Mark Beck <beckmk at whitman.edu> Subject: single-step vs. multi-step mash? I'm a relative newbie to all-grain brewing, and so far I've made some IPA's using single-step infusion mashes (a couple of which have turned out pretty darn good!) However, soon I hope to brew a Belgian Triple, and I'm contemplating using a multi-step mash. I plan to use a pilsner malt. In the Classic Beer Styles on Belgian Ales, it says that the recipes are calculated for a single-step infusion mash "for simplicity", or something like that. However, in the chapter where brewing details are given, a multi-step mash is described. So: Do I need to do a multi-step mash? What are some possible differences in flavor, attenuation, etc.? Any hints on brewing a Triple would be appreciated. Mark Beck Walla Walla, WA Return to table of contents
Date: Fri, 14 Mar 2003 09:47:07 -0800 From: "Mike Sharp" <rdcpro at hotmail.com> Subject: RE: Is Dry Ice Filthy? "FLJohnson at portbridge.com" wonders if Dry Ice Is Filthy? The dry ice I've bought was made on the spot, in a wooden box that just they just set on the floor. No sanitation whatsoever, nor any cleaning that I could see, aside from shooting a bunch of liquid CO2 into it. If you pay extra, they put it in an unsanitary press and compress it. So, yes, it's filthy, IMHO. But at bottling time in a bucket, I don't think you have to worry--you're priming with sugar and getting the yeast going again...I force carbonate, and purge the keg with CO2 prior to transferring into secondary and then when transferring to the bright beer keg.

Date: Fri, 14 Mar 2003 11:04:51 -0800 (PST) From: Michael Hartsock <xd_haze at yahoo.com> Subject: Iodine based sanitizers I just came across this product that seems like a much better option for brewers, in terms of cost. For $13.90 a gallon, with a no-rinse dillution ratio of 1 oz to four gallons, Hillyard's product is FDA approved and used in restraunts and dairy tanks. >From their site (Hillyard.com): H-101 (HIL0012706) Concentrated sanitizer/deodorizer formulated especially for food contact surfaces. Ideal for sanitizing food utensils, countertops, drinking glasses, dishes, silverware and refrigerated storage and display equipment. 1:512 dilution rate. EPA registered and approved by NSF Category D2 for all surfaces in federally inspected meat and poultry establishments. I don't work for Hillyard, or anything - but this seems like a cost effective alternative. Hillyard has distributers in most major cities, and sells directly to the public "anyone with money", so said the sales representative I spoke with. Mike ===== "May those who love us, love us.

Date: Fri, 14 Mar 2003 15:08:38 -0500 From: ensmingr at twcny.rr.com Subject: out of style There have been some recent posts in the HBD about competitions and 'out of style' beers. If you're worried that your beer is out of style but you still want to enter a competition, you can enter it under category #24, "Specialty / Experimental / Historical". This category includes just about anything and judges look for "a harmonious marriage ingredients, processes and beer". See: <http://www.bjcp.org/styleguide24.html>. I have the most fun judging this category, because you get some really interesting efforts, sometimes very good and sometimes very bad. Cheerio! Peter A.

Date: Fri, 14 Mar 2003 16:21:24 -0500 From: Donald Hellen <donhellen at horizonview.net> Subject: refractometer recommendations for beermaking??? Some of you use a refractometer, so this is for those of you who have experience with them. Are the imported Chinese-made ones worth the $60 they cost? If not, which would you recommend? I don't want to spend more money than necessary, but I don't want to waste money, either. I would use this for homebrewing beer and sometimes possibly winemaking also. I may not be able to check back and read your replies until Monday (maybe, maybe not), but I assure you that I will read them. If you have links to places where I can buy one that you recommend, I am interested in that (or addresses/phone numbers). Thanks in advance. Don Hellen Return to table of contents
Date: Fri, 14 Mar 2003 16:22:32 -0500 From: "Martin Brungard" <Martin.Brungard at trow.com> Subject: Water Analyses A number of interesting problems have been posed regarding water analyses lately. A bad looking Chandler, AZ water and a question regarding bicarbonate levels in Burton water. Mike Walker had questions about the Chandler water. I copied the analysis below. Calcium = 73 mg/L Magnesium = 27 mg/L Bicarbonate = 200 mg/L Sulfate = 130 mg/L Sodium = 200 mg/L Chloride = 291 mg/L Hardness (as CaCO3) = 290 mg/L Alkalinity (as CaCO3) = 200 mg/L pH = 7.59 He recognizes that the water is largely unsuitable for brewing and treatment. Diluting the water is the easiest treatment option to reduce the high ion contents. A 1:1 dilution with distilled or RO water will still leave the water with an excessive chloride concentration, especially if the sulfates are going to be increased for a hoppy beer. It appears that a 2:1 dilution would bring the water into a pretty good range, suitable for amending into many water styles. Using the dilution should be preferable for most beer styles excepting pilsners. Having those ions in the water saves some time and money over using 100% distilled or RO water. By the way, distilled and RO water is not a good thing for water supply piping nor is it especially good for human consumption. My background includes substantial water supply engineering and design. Distilled and RO water are very corrosive for the piping. Water companies like the water to be a little hard and alkaline so that the corrosivity is minimized. For human consumption, we need a supply of these ions to maintain our body chemistry. Gatorade didn't make millions for nothing! Besides that, the ions give the water some taste. Most water system users prefer a little taste to their water. David Humes found an anomaly on the makeup of Burton water. Some resources list the bicarb as high as 320 and others list it as 0. I did a quick check of the anion and cation milliequivalents to see if they balanced using some Burton water analyses I had. I can say with confidence that the report of 0 ppm for bicarbonate in Burton water is not correct. I see that Ray Daniels recently pointed out the oversight. The anion/cation check and my review of other sources says that the bicarbonate concentration is likely in the range of 140 to 200 ppm. While I was at it, I reviewed the Burton ion concentrations shown in the Promash program database. It appears that at least one of the ion concentrations in the Burton profile is incorrect. I suggest that the reported calcium concentration of 268 ppm is the culprit. It appears that the calcium should be on the order of 200 ppm. That would bring the calculated hardness for the Burton profile into line with the data I have. It appears that Promash users should amend their Burton water profile. Hopefully Jeff Donovan will review and incorporate that change into the program database too. Martin Brungard Tallahassee, FL Return to table of contents
Date: Fri, 14 Mar 2003 17:14:23 -0800 From: "Ryan and Shelly Furstenau" <furstenau1 at cox.net> Subject: Actual Guinness Ingredients I have seen many formulas/recipes out there for Guinness clones. Some of these perplex me. To my knowledge, Guinness uses a British Malt, Roasted Barley, and Flaked Barley. The hops type I am not certain of. Anyway, many of these recipes have rolled barley or black patent malt, or even corn sugar. This past year I took at trip to Ireland and my tour of the Guinness brewery confirmed the 3 main ingredients that I listed above. Can anyone else confirm that Guinness only uses these 3 main ingredients in their beer? If I am correct, why would any Guinness "clone" include ingredients that aren't in the actual recipe. If I am wrong, please correct me. Ryan Omaha, Nebraska Return to table of contents
Date: Fri, 14 Mar 2003 16:06:51 -0800 From: "John Palmer" <jjpalmer at altrionet.com> Subject: Re. Burton Water Profile The recent discussion of Burton water chemistry reminded me of an analysis I had obtained back in 1998. I was researching my water chapter and, given the electrical mutual exclusion of the ion concentrations given in Malting and Brewing Science, Practical Brewer, et al., I thought to myself, "Hey, I will just call them! I mean, people still live there right?!" What I finally did was got on the UK Digest, and requested that someone call the water dept and get an analysis. And they did, and here are the results. Note that this analysis is for one particular source and one particular sample. Given Ray's comments on the variability of the water with depth, this data makes sense in view of the published profiles. Source: Blithfield Reservoir Date: 28/05/98 Time: 11:35 pH 8.26 Alkalinity as HCO3 152 ppm (ie. bicarbonate ppm) Total Hardness as Ca 83 ppm (not sure how to use) Perm. Hardness as Ca 33 ppm (not sure how to use) Calcium 57 ppm (but since I have this I don't need those above) Magnesium 15.8 ppm Sodium (not reported) Potassium 5.7 ppm Iron .061 ppm Manganese .012 ppm Chloride 26 ppm Sulfate (not reported) And that is why I did not use the info in my book, because the sodium and sulfate were not reported. However, this information does give you the residual alkalinity of the water which is 70 ppm as CaCO3. This equates to a base-malt-only mash pH of 5.8, which suggests that the water is best suited for an amber colored beer. Which it is, historically.
