(Don't ask me which issues though). Your amount is WAY TOO MUCH THOUGH!!!! They sell TSP at the local wine shop, here in Berkeley. The instuctions are either 1 tsp or 1 tbs. per gallon on warm water (I honestly don't remember and I don't have any tsp at home to look at. I'll check the bottle when I get a new batch and let you know. While the labels don't just float off, you can generally pull them off by hand after 30 minutes of soaking. I have not tried soaking over night though. How much are you paying for TSP at the paint store? It might be interesting to see if it is cheaper from the paint store than from the wine shop BEFORE I spend the money.

Don't get the different types of extracts used confused. If you're using a pre-hopped extract (i.e. a beerkit) you should boil as short as possible (10 -15 min.) only to sterilize the wort, because the hop flavours will deteriorize upon boiling. Here in holland a lot of these kits require only to boil the water, cool it and then dissolve the (liquid) extract after which the yeast can be added (no mention of areation whatsoever btw.). If you use extracts and add hops separately you must boil longer to get the right hop utilization, but limiting the boiling time to 60 min. is indeed better, because of excess darkening of the wort. I've found it very difficult to get a light colored beer (as you would get from malted grains) from (dry) extracts. Light DME is already darker than pilsmalt so you need to keep the OG down for a light colored beer and long boiling times add even more to the color. Constant stirring (watch out for HSA) and tempering the burner as much as possible during the boil should reduce darkening. Otherwise if you treat dry extracts as all-grain during the boil (i.e do a full boil) the results can be suprisingly good. Bye, Wim.

I aerated both starters >well (I think), and re-aerated them when activity slowed - to >no avail. What am I doing wrong? In my experience, the source of fermentables can have a dramatic impact on starter viability. Early this year I bought a bag of DME for starters and had a dreadful time getting them to go (*extremely* slow fermentation). Over a series of attempts I tried supplemental yeast nutrient, increasingly higher levels of aeration, and several different yeast types (all the slants I tried are still viable today). Result: little/no improvement. (A procedural note: my starter OG is always about 1.030). Out of desperation I made up a starter from a little all-grain batch (but otherwise used the same starter prep procedure). Result: Massive Improvement. We're talking night and day here. Of course, I'll be happy to provide full details to all who ask. I don't want to give the impression that I know why (I don't yet). Now here's the question: For the sake of discussion, let's assume that my DME contains significant amounts of glucose and/or other "simple" sugars (this is pure speculation). Could my problem be a manifestation of the Crabtree effect? Todd Mansfield Cincinnati, OH TMansfield at mcimail.com Return to table of contents

I used Wyeast 3068 Weihenstephan. I also tasted a Raspberry Weizen, from a friend, also made with Wyeast 3068 Weihenstephan. My opinions, for what they are worth: 1) The Wyeast 3068 does a good job if you want a plain (non-fruit), authentic-tasting Weizen. (Takes the longest to ferment of any yeast I've used--about 14 days in a closed primary fermenter, with 1 package/5 gal., no starter.) 2) Although I can recommend this yeast for a non-fruit beer, I don't think its flavor makes a good combination with fruit. The fruit beers I've made and tasted are better when the fruit/malt/hops flavor and aroma are not competing with the dominating flavor and aroma of this type of yeast. Good commercial offerings tend to agree with this theory--i.e., Pyramid Apricot Ale does not taste like it uses an authentic weizen yeast, and neither does Wynkoop Backyard Ale (peachy wheat). 3) I definitely recommend using the secondary for your addition of fruit flavor. Frozen raspberries (I've used Bel-Air brand from Safeway), steeped in hot (160F) water for 30 min. before addition to secondary, work great. I used 4 - 5 lbs. in a very successful Raspberry ESB recipe. You could use less, especially for a lighter, less flavorful beer. I was less impressed with the use of fresh apricots--part of the pulp tends to float, and I had more problems during siphoning/bottling, resulting in less yield, and some apricot flowing out first from some bottles. If I make an apricot or peach wheat beer again, I will use a neutral yeast like Wyeast 1056, and might use all-natural extract flavoring, or just pour the steeping water into secondary, leaving the fruit pulp out.

Date: Sun, 10 Sep 1995 21:45:01 -0400 (EDT) From: Tim Laatsch <LAATSCH at kbs.msu.edu> Subject: Dark malt in lauter-tun Hey All, I mash on the stovetop and lauter in a zapap. I've noticed that I tend to get oxidation with dark malts, a problem that I believe has two sources: transfer of hot mash to lauter-tun and manual recirculation. Regardless of how careful I am not to induce HSA, the problem persists with varying degrees of intensity, but usually just enough to be irritating. My proposed remedy is to add any dark-roasted malts to the lauter-tun AFTER the manual recirculation phase. My questions are: Will this work? Is there any reason NOT to do this? Could crystal malt be handled the same way? Your opinions are welcome---I'll summarize any privately received info. I have to get my stouts and porters back on-line with the early arrival of brisk fall weather here in Michigan! BTW, many thanks to all of you for the advice on improving my American Pale recipe---I'm happily reaping the dividends! I've found that a small proportion of Munich malt contributes a pleasant, soft, and creamy malt texture. Having little experience with Munich malt, I'm wondering: is this the standard Munich effect?

I have been enjoying the wealth of knowledge presented by the subscribers of HBD. Recently much has been said about Gelatin, though I am lacking clarification on 1 aspect. Once the Gelatin has been dissolved and poured into the carboy, is there any need to stir, shake or otherwise try to homogenize the beer? If so, what is the best method.

Date: Mon, 11 Sep 95 09:38:42 EST From: "MSG Richard Smith" <QR1661 at trotter.USMA.EDU> Subject: Stuck Fermantation or High Finishing Gravity? I brewed 10 gallons of all-grain using 19lbs English 2 row and 3 lbs of English crystal. Everything went perfectly, and I hit my target of an OG of 60 a little high at 62. I split the batch into two 5 gallon carboys and pitched one with 10 grams(2 packages) of Doric dry yeast and the other with 12 grams (2 packages) of Munton and Fison dry yeast. The yeast was properly hydrated and both fermentations went as expected except that I thought they stopped bubbling perhaps a day too soon. I took a gravity reading on the 6th day after 3 days of absolute zero activity and got readings of SG 26 in each carboy. I thought this a little high and added some yeast energizer. 1 day later nothing. I repitched with 11.5 grams (1 package) Edme dry yeast each. 2 days later- nothing. I tried rousing the yeast too - nothing. My own conclusion is that I should have used a more attenuative yeast (liquid?) to hit my desired final gravity of 14-15. Is liquid yeast the only answer or is there a better dry type to use with OGs over 50? Any comments would be appreciated; even flames for using dry yeast in the first place. TIA- Jack Richard J.

Date: Mon, 11 Sep 95 09:39:07 EST From: gravels at TRISMTP.npt.nuwc.navy.mil Subject: Yeast sludge / sediment in bottles Hi All, Bill Cole asked in HBD #1827 about saving the sludge from a previous batch. I'm a firm believer in using the yeast sludge from my last batch, it gives me a huge starter and saves the $3.75 I pay for Wyeast packs. Here's my procedure; Before I rack the beer off of the yeast and start to bottle, I boil a mason jar in about 2 inches of water (lid on the pot) for about 15 minutes then let it cool while I bottle. I rack the beer into the bottling bucket leaving a little beer on top of the yeast. I clean and flame the neck of my carboy, this is the secondary fermenter, swirl the liquid around to get the yeast into suspension and pour off the liquid into the sterilized jar. Put the sterilized lid on and put it in the fridge. Once the yeast settles out you can decant off the beer and replace it with cooled boiled water to clean the yeast, I don't always do this part. I've collected the sludge from the primary fermenter also, but someone (sorry, don't remember who) said that the yeast from the secondary are more desirable because they are less flocculant?! Anyway, either method works. I used the yeast sludge I had stored in the fridge two months ago to make a 1/2 gal starter and this batch was underway in less than two hours! Alex Wetmore in HBD #1828 is concerned about the sediment in his bottles. The sediment is probably not the sugar, I don't bring the sugar to a boil either and have had no problems, what you are seeing is the yeast settling out. I'm not sure when you should actually be seeing the yeast sediment begin to form (I don't check the bottles that regularly), but I wouldn't worry about your beer. It sounds as if your procedures are correct and your beer is going to be just fine. Steve "Homebrew, it's not just a hobby, it's an adventure!"

In any case, as long as the 3/4 cup was for the whole 5 gal batch - not 3/4 for every pint. >our questtion is if we should try and mix this sediment back into each beer in >case it is sugar that went out of suspension too early. We would rather not end up with un-carbonated beer. As long as the sugar was liquefied prior to adding it to the batch, it should not have settled out. Papazian (and others) recommend bringing to a boil to assure that any contaminants (wild yeast, bacteria, etc) present in the unboiled water wil be killed. By "mix" if you mean shake the bottles, there will be no damage but the beer will simply have to settle again. If you mean open the bottles, dont do it because you'll risk infection and/or overcarbonating if you add more sugar. Return to table of contents

Date: Mon, 11 Sep 95 12:26:56 -0400 From: joep at informix.com (joep) Subject: ? yield has gone down :( Hi all, My turn to ask a question (and start another thread). Of course, thanks to the whole for the insightful and entertaining reading material (I am actually a contributor <g>). Since I've gone all-grain, my yield has gone down. I've done three batches (w/two pots) and I've been getting 3-3.5 gallons of finished product where I should be getting closer to 5. <heavy sigh> To correct the problem, I have just recently purchased an 8 gallon pot. This should cut down on evaporation loses due to two pots. This will also, theoretically, allow me to start my boil with 7 gallons, losing 1.5 to evaporation and .5 to hot/cold break. I realize I'll lose a little more in the fermenter, but that would be ok. Does this make sense? I don't think I've been sparging enough. If I sparge to 7 gallons with which to start the boil (60 minute boil), will I be ok? Am I better off sparging less and adding some water? (fyi, the next batch will be a doppelbock, starting with 17# of grain.)

Date: Mon, 11 Sep 95 12:56:40 PDT From: Rob Emenecker <robe at cadmus.com> Subject: ss airstones A quick question for the collective... Over the past few months I made the switch to full volume boils and chilling with a counterflow chiller. For aerating I was concerned that an aeration wand (drilled tubing) would clog with cold break from the chiller. Instead I have opted for using an aquarium pump to aerate my cooled wort. The two problems I have experienced with this method is 1) sanitizing the small aquarium airlines/tubing is a PITA (but I will tough it out) and 2) the airstones I have like to float to the surface. I am assuming that the weight of a stainless steel airstone will sink it to the bottom of my carboy. Am I right of am I wrong? I have looked around the local pet stores and cannot find SS airstones. Where do I obtain these ellusive goodies?

First, they package and sell it labelled as B. Brux. An interpid homebrewer plates the stuff and does some microbiology stuff to it and declares it to be almost purely S. Cerv'. He does this to a couple different batches, and posts his results. He and his net access provider get a threatening letters from Wyeast's lawyers. Finally, they post saying that it was 90/10, and that this information was available for the asking. I said there, and will say here, that a boycott is a bit of a PITA for me.

I've heard it from numerous sources. Last night, I was pitching a starter (for use next weekend, FWIW), and I read the Wyeast Packet. Wyeast recommends pitching a starter at high kreuzen. So, should I boycott Wyeast, boycott the HBD, or just start drinking Leiny's Ice and forget about brewing? (As far LI goes, btw, I pretty much lost any 'faith' I had in them when they release their honey weisse. Not a terrible beer, but the ad campaigns encouraging people to call it "Weece" didn't sit to well with me.

Here's some information I got from Jeff Lebesch, the man behind New Belgium Brewing. It's from a handout he had at a talk he gave to the local brew club a few years back: "Most references recommend a minimum pitching rate of 10 million yeast cells per milli-liter of wort, plus another 1 million cells/ml for every 0.004 gravity increase above 1.040. ...The 10...15 million cells/ml rate is easily achieved by adding 5 ml of thick yeast slurry per liter of wort. For ales, sometimes you can go as low as 3 ml/l, and for low temperature lager fermentations 10 ml/l is suggested. "During a healthy fermentation, the yeast cell count increases to a peak of approximately 60 million cells/ml. Then it seems to me, that given the 10M cells/ml minimum pitching rate, the maximum wort volume increase should be six-fold.... However, many references suggest that a 10-fold increase is acceptable. "...If 600 ml of starter culture is pitched into 18 l of wort (about 5 gallons), that is a 30-fold wort volume increase. In most situations, this is drastic underpitching. The only way it will work is if the yeast is at its peak activity and viability... plus wort conditions are optimal. "OK, let's culture another generation, by adding the 600ml culture to 3 liters of wort, and adding that to the 18 liters. Now each generation has had a wort volume increase of less than 6.... But, adding 15% of a cheap culture wort to your prized wort will ruin it. One solution is that the culture wort must be of the same composition as the beer.... This is common in breweries where the same beer is brewed every day.... The other solution is to let the 3 liter culture ferment to completion, then refrigerate... then pour off the top beer, and collect the yeast slurry." This doesn't address the question of when to step up or pitch your starter (in fact, the last sentence says "ferment to completion"; that's probably not what you would do normally when stepping up your starters). However, it's clear that a 1L *yeast cake* would probably be over- pitching by a bit. The maximum liquid wort increase of 10-fold would indicate a 1.8L starter for 18L (5.2 gal). - -- Jeff Benjamin benji at fc.hp.com Hewlett Packard Co. Fort Collins, Colorado "Think!

It's at mashout temp, 77 C, and splashes like mad. I would say that, yes, this is a problem. Personally, I make most of my beer in an EasyMasher(tm), so there is no transfer of mash at all. Recently, I did make a few non-EM batches in which I "glorped." "Glorping" is a term I picked up from someone (sorry) at the Chicago Beer Society and is the transfer of mash from mash tun to laeuter tun by using either a saucepan (or even better, a dedicated "glorper") one scoop at a time. By doing this, you can gently lay the mash down in the laeuter tun and minimize aeration. >Next, during recirculation I pour the first runnings back into >the top of the bin onto an inverted saucer--more splashing. I can't reach >in to the bin with my pitcher, so it pours from the 25-30 cm height >mentioned above. Again, I believe that this is a problem. I use a small measureing cup for catching the early runnings and therefore I can again gently lay down the runnings back into the top of the laeuter tun without aeration or disturbing the grain bed too much. I must admit that there is a disadvantage to the small measureing cup in that I have to stop the runnoff between cups of runnings. I have to think more about solving this problem since starting and stopping the runnings has a tendancy to un-seat the grain bed a little each time. *** Kevin writes: >There seem to be two schools of thought here: The first is that skimming >the scum is a good thing because it helps prevent those nasty boilovers as >well as providing you with something to do while waiting for the long boil >to get done and over with.

It is literally cooked protein and, according to DeClerck, *must* be removed. Yes, it will settle out with the cold break. No, removing it does not reduce head retention because it is made from the large (haze-forming) proteins and not the small (head-retaining) proteins. The fact that removing it does reduce the chances of boilover is an added benefit. Personally, I skim. Al. Return to table of contents

I brewed a Belgian Triple last week, OG 1.092, all grain, and pitched probably about 20 oz of slurry that I recovered from the end of a Belgian Single ferment, 1.049. I went away for a week and didn't even know if it was going to ferment but when I returned I was glad to see the airlock slowly bubbling and the marks on the carboy indicate that the krausen had risen and fallen. I checked the gravity and it was only 1.060! I know I didn't aerate very well, believe me I wanted to but don't have the equipment yet. Will soon though. I was wondering what I should do. I think I will grow up some more yeast and repitch. Any thoughts other than just wait and see? I am using the Westmalle yeast cultured from the bottle and have been told others have had stuck ferments with it when doing high gravity brews such as this. I have used it before on a batch of double aroudn 1.065 and it worked fine except for some sluggishness after racking. Also had a question about Belgian specialty grains. How come most of the roasted grains, chocolate, black, unmalted, have higher Lovibond ratings than English and American grains. I asked this once before but didn't get any response.
