---------------------------------------------------------------------- Date: Fri, 12 Mar 1999 12:32:46 -0500 From: "Conan Barnes" <barneco at earthlink.net> Subject: yeast starter temps, oatmeal stout extract recipe? hey folx, I'm pretty new to homebrewing(on my 3rd batch). still sticking to extract kits til i build up some kinda proficiency. my first batch, a pilsner ale, turned out pretty good. for the second batch, i added a wort chiller and a few technique improvements gleaned from books, HBD etc.. and my IPA turned out excellent. for my third batch i decided i try to make the leap to liquid yeast. i'm planning on a Honey Brown Ale, and thought i'd try wyeast 1028. my question, is this yeast known to be slow? or have i done something wrong? i bought the pack on sunday and started it. 2 days went by with no activity. so i put it on the hot water heater(not very hot, just not cold like the rest of the house), and the pack swelled up in 24 hours. so i brewed a starter and pitched it. after about a day i could see activity and the airlock was moving(slow, but moving). i expected to see a good Krausen soon, so i'd be ready to pitch it saturday(tomorrow), but instead, the activity slackened, then stopped all together. i've noticed that the yeast has pretty much all flocced and looks pretty much like trub after a primary. my guess is that my temp was a bit too low. anyone else ever have this problem, and has anyone come up with some nifty gadget to maintain a 70-80F temp in a champagne bottle? On a quick second note, anyone have an extract recipe for an oatmeal stout, if such a thing is possible? thanks in advance, Conan Barnes Return to table of contents

I've been meaning to post my version for a few years now. I still have many bottles, so I've no idea when I'll get to make it again. It is strong stuff. Chocolate Thunder Wyeast 1098 (or any British ale yeast) 90% British Pale Ale 4% Crystal 90L 4% Crystal 40L 2% Chocolate Sparge to 1/2 gal. less than usual. 2 lb. Honey pasteurized with 2 qts. H2O. (do not add directly to boil) O.G. from the malt alone should be around 1.070, and after adding the 2 lb. of honey, you should be around 1.080. Finishing gravity is around 1.012-1.015. Somewhere around 9% ABV. Keep the mash temp. high to balance the bitterness of the chocolate. No bittering hops. Mash at 153F for 60 min. 6-8 oz. baking cocoa add the baking cocoa 60 min. before knock-out 10 IBU of E.K. Goldings added at 15 min. from knock-out. Age for one year. -SM- Return to table of contents

I have a JSP adjustable maltmill that I would like to motorize, and I have some questions. (1) What speed/power characteristics do I want on the mill's shaft? (I.e., if direct coupled, the motor characteristics. But, if I use any gear or pulley reduction, what do I actually want to provide at the mill's shaft.) (2) Is it a problem to have the motor directly coupled to the mill's shaft? What about rocks in the grain? (3) If (2) is a problem, what is the solution? Belt driven? I know that a lot of people have used drills. BUT, are there _potential_ problems with this? Anyway, I may be able to get some "scrap" motors since I work for a manufacturer of brushless dc motors and controls. Also, if I know the characteristics I need, I could even wind one by hand to give me what I want. So, what do I want? Brew on!

About 75% claimed an explosive start to fermentation but the other 25% referenced very long lag times. I have recently used this yeast twice and found both times that the lag time was huge.

Greetings to all, As a recent subscriber to HBD, I have found the information and discussion quite useful to my brewing efforts. A thank you also to the Janitors for maintaining HBD. The issue: I began brewing a few months ago from extract and all grain kits, producing some very nice, drinkable brews. A friend noticing a slight haze in my beers, suggested using chitosan to fine them before bottling. Unfortunately, he was unable to tell me what chitosan is made from and whether it would be a good fining agent. I have searched the HBD archives and came up with nothing. If anyone has any information on chitosan, please share your knowledge. Thank you in advance for your replies Harry Ewasiuk Red Deer, Alberta, Canada email:shogun at ccinet.ab.ca 'So then I says to Borg, "You know, as long as we're under siege, one of us oughta moon these Saxon dogs."' - G.

It's about time to bottle my barleywine. Thanks for the help." It's the perennial barley wine bottle question. I know that there are small beer bottles manufactured in the US, I bet someone could make a decent amount of money selling them to desperate home brewers (I'll take a few cases). I understand that a manufacturer would probably require a large purchase of bottles, but couldn't the larger mail order home-brew suppliers (or the wholesalers that supply them) deal with that?

Date: Sat, 13 Mar 1999 18:39:42 EST From: WayneM38 at aol.com Subject: Decline of Homebrewing (Homebrewing plants the grains of it's own demise..) Dan Listermann dan at listermann.com or 72723.1707 at compuserve.com >> writes: << There is another factor that I believe feeds this situation. The demogrphics of homebrewing are easily contained inside the demographics of new computer users. Computers are sucking up the money for homebrewing and, even more importantly, the time for homebrewing. I am starting to believe a turn around in homebrewing will not happen until the newness of computers has past. Considering the rapid advances computers keep making, this point could be some time off. The industry may have to satisfy itselfwith people who really enjoy the process of making great beer not just drinking it. I am not so sure that this is a bad thing. We have to find these people. I kinda like them.>> Dan: I have been working closely with another hobby group as part of my job for the last 12 weeks. I have chatted with them and the vendors of their equipment. They are passionate about their hobby, just like homebrewers. Every addition to their hobby (model railroad) is an another improvement and investment. Ever see a $1000 'G' scale locomotive or a $3000 LGB engine and rolling stock setup? I thought that a PicoBrewery was expensive.... With our hobby, as one gets better and after one moves to all grain, the investment in materials and expense actually drops!! If you follow rec.crafts.brewing, brewers are mashing in picnic coolers and fermenting in plastic pails. Some boast that they have had the same pail for over 5 years! Hard to make a living selling plastic pails to homebrewers. A lot of equipment is purchased or built without the homebrew shop as a source. That is the nature of this hobby. A few years ago, I started with extract batches which cost about $20-$25 each. I was visiting at least two shops every month for supplies. I now do 10 gal all grain batches. A 50# bag of domestic malt is about $22. That drops the base malt cost to about $4 a batch. I now brew better beer in bigger batches, less often. That is not good for shop owners. It should be the other way around. Start out with less expensive ingredients and move up to more expensive ingredients (grains to extract ?). Instead of two trips a month to the shop, now it is only one or less. This fall, I hope to start yeast cultures of my three house brews. No more $4 yeast packs. This puts the homebrew shop owner at odds with the natural progression of this hobby. At least at the high end of the hobby. In order to improve my technique, I like to brew as often as possible. In order to brew more, I try to split 10 gal. batches with a fellow homebrewer. This is the best use of my time and equipment and a way to explore the different styles I want to brew. There was an interesting post to RCB a week ago. The homebrew shop was charging a surcharge of 10% for grinding grain at the shop. At first glance, it seemed a bit excessive, but from a shop owners perspective, a good business decision. I am fortunate to have 5 homebrew shops within 30 min. driving distance. I try to frequent the top 3 as much as possible. I will do my best to keep these local guys in business and move forward in the hobby at the same time. Then there is that 100 gal limit........ Just my opinion. Wayne Big Fun Brewing Milwaukee Return to table of contents

Perhaps you do not wish to "debate" but I, on the other hand, do not wish to have you impugn our product no matter how subtle your approach. No sooner do we get kudos for presenting an honest, tempered discussion than you have to spoil it with hype, inuendo and misinformation. "One of the prime reasons that brewers get poor extractions is poor crushes. This is especially common amoung beginning all-grain brewers because of a fear of getting a stuck mash. Inconsistant crushes cannot be looked upon as an advantage. "Magical" gap settings will produce inconsistant crushes. This is clearly a code-worded trashing of the "Pre-adjusted MM and you are now going to have to prove this nonsense. But of course you must begin by defining "inconsistant" crush and then you have to prove that the extraction is inferior to what can be achieved with your mill and then you can collect the prize that I have offered for years to anyone who can prove that beer made with an adjustable mill is in any way better than that made with a pre-adjusted MM. "I crush by visual inspection never worrying about what the gap is. Me too.

Date: Sun, 14 Mar 1999 00:30:34 -0500 From: sedam at bellsouth.net Subject: backdoor dealings Dan: I work at a homebrew shop that was the victim of a "backdoor buy" and can assure you that it does effect the bottom line of the shops. Don't you think a homebrew shop would want to sell someone 2,000 lbs of grain? That's only 40 bags of grain--easily within the realm of an industrious group of brewers. For the $3/ bag you might save, you'll kill the local shops. It's not anything close to whining...it's real life business. How do you think a restaurant would do if you could bring your own ingredients and just have them cook it? Same thing. I hope you'll be a little more sensitive to the issue and, if you don't beleive what I'm saying, ask the owner of your local shop how he/she feels about the topic. That might educate you better than I ever could. Cheers! Marc Sedam Chapel Hill, NC Return to table of contents

OK, 1) so BrewingTechniques has decided to take the lead in promoting homebrewing as a hobby by making high quality commercials available to homebrew shops, (go to http://www.brewingtechniques.com/library/backissues/issue7.1/editorial.html for details) and 2) by their own admission the AHA supports the legalization of homebrewing in Idaho "in a minor way with a sample letter e-mail campaign to AHA members in Idaho." So 1) another organization has taken up the cause of the promotion of homebrewing, and 2) individuals are getting homebrewing legalized in other states. Can someone remind me what the AHA is for?

Date: Sun, 14 Mar 1999 16:53:49 GMT From: mrreid at golden.net (Ross Reid) Subject: Implosive carboys My thanks to both Dave, who responded here in the Digest and, to another via email. My career as a vacuum transferrer has come to an end. This old mug of mine might not be handsome but, it's the only one I've got. However, I do have one related question. In my original post I mentioned a vacuum setup, sold by one national winemaking/homebrewing wholesaler, mainly for BOP operators to speed up the finishing of wine by vacuum de-gassing. In operation, the glass carboy (or many carboys) of wine is/are connected to the vacuum pump which is left running for 24 or more hours. Is the inherent danger of implosion in an almost full carboy less than in an almost empty one, or is this set up also dangerous? I do have a small pump that I can use which will be fine for same level transfers but, I don't know what kind of a flow rate it'll produce with a 10 foot head bringing wine/beer up from the basement. I guess I'll find out later this afternoon, but I'll test it with water first. Again, thanks for the advice. Cheers, Ross. Return to table of contents

Date: Sun, 14 Mar 1999 09:27:05 -0800 From: kchris1 at lausd.k12.ca.us Subject: Mimimash pH Questions HBDers, I have an old question for you. It has been a few years since I have done an extract batch and I would appreciate it if you could help me clarify a few pH questions that are nagging me. This is going to be a 12 gallon batch of stout 12 lb Scotts LME minimash with the following Breiss Malts 2 lb 2-row 1 lb carapils 1 lb flaked barley 1 lb roasted barley .5 lb chocolate If I mash all the malts together at one time, I am concerned that the pH will drop too low and give me a poor conversion. Is this a valid concern? Dont know much about my water chemistry, but my all grain mashes fall into the 5.3 5.5 range. The last 2 batches were CAPs and it went right to 5.4 with no dark malts. Should I mash the 2-row with the carapils and flaked barley while adding the roasted barley and chocolate at the end of the mash? The other alternative is to do a separate mash for the chocolate and roasted barley. What do you think. Thanks Keith Brewing a beer that not even sighted folks can see through ;-) Return to table of contents
Date: Sun, 14 Mar 1999 12:47:45 -0500 From: "S. Wesley" <WESLEY at MAINE.MAINE.EDU> Subject: The Energy of Implosion - Carboys and Pressure. The Energy of Implosion - Carboys and Pressure. From: Simon A. Wesley In HBD #2975-18 Ross Reid asks about using a vacuum pump generating -15" Hgg. to lift beer from a carboy in his basement to the next floor. He also asks about using lower level vacuum or C02 pressure to do same level transfers. My advice to you Ross is to get yourself a small regular pump to accomplish this job. For a modest amount of money you can virtually eliminate all risk from this process. If you wish to continue using your vacuum pump here are a few things you should keep in mind. At first glance 15" of vacuum applied to an empty carboy may not seem like that big of a deal. In reality, if the carboy does fail this is probably just as dangerous as doing vacuum evaporation in a carboy at -28.5" Hgg. The energy released by an empty 20 litre carboy (roughly five gallons) failing under these circumstances is 311 J. To put this in perspective this is the energy that would be released if you dropped a full carboy from a height of about 1.5m (chest height) to the floor. Compare this to the energy released upon failure of a 20 litre carboy holding 16 litres of beer at 28.5", which is 324J. Of course it is probably less likely that the 15" carboy will fail, but if it does, the results might be similar if not worse. Dave Burley and Louis Bonham have clearly stated that they feel that evaporating beer from a Pyrex carboy would be extremely dangerous and have strongly advised against doing this. In HBD #2976-14 Dave Burley responded to Ross's post by suggesting the use of a wooden box as an implosion shield for Ross's receiving carboy. This is in fact the approach that is taken in many vacuum applications involving large glass containers which require heating, although the implosion shields are not usually made out of wood. If Ross chooses to continue using his pump he would do well to follow Dave's advice in this matter. As an alternative, an implosion shield could be made out of a small metal trash can or a heavy duty plastic trash can or bucket. Even if you do use an implosion shield proper eye protection should still be worn at all times. I prefer to use a full face shield. In order for an implosion shield to be effective it needs to be used. I would recommend that Ross make a habit of NEVER PUTTING HIS CARBOY UNDER VACUUM WITHOUT THE SHIELD IN PLACE. I would also suggest that a small peephole should be made in the shield so you can see what is going on inside. This will reduce the temptation to lift up the shield to peek. Consider the following unpleasant scenario. You kneel down next to the carboy, and lift the heavy wooden shield. Your body and your face are right next to the carboy. You accidentally bang the carboy with the shield and it fails. You could be badly injured or even possibly killed. With regards to lower vacuum transfers (-5" Hgg) and low pressure (2.5psig) CO2 pressure transfers it is still probably a good idea to use a shield. I find that my carboys will fit inside the plastic buckets sold as fermenters in homebrewing stores. A 2.5" hole cut in the bottom of one of these would turn it into a cheap effective shield. Don't forget the peep hole and of course the eye protection. In closing I would like to make one other comment about transferring using CO2 pressure. Ross with his bad back has a good reason for looking for an alternative to siphoning to do transfers. I understand that some people use CO2 to transfer because they think it reduces the risk of oxidization. If you choose to do this you would be wise to keep the pressure as low as possible and consider using a shield. Carboys are almost certainly much stronger under vacuum than under positive pressure. The -15" Hgg Ross was using creates a pressure difference of 7.5 psi between the inside and outside. I would say that using this much pressure to transfer is a lot more dangerous than using 15" of vacuum. Return to table of contents

In summary, concentrations are as follows: Calcium 11.8 mg/l Sodium 2.1 mg/l Magnesium 2.0 mg/l Alkal. (as CaCO3) 24.0 Hardness 37 Sulfate 16.13 Chloride 6.7 Ph 7.8 (I think these are the important ones). I have been making all-grain beer for a few years and have never treated my water. My beers have in general been very good i generally get 28 pts/lb/gallon. Most of the time i brew german lagers and wheat beers,but i do brew other styles as well. Is water treatment really something i want to get myself involved in? In other words, will it significantly improve my beers, or simply make things more complicated? Thanks. Tom Barnett.

Date: Sun, 14 Mar 1999 16:09:15 -0700 (MST) From: Adam Holmes <aaholmes at lamar.ColoState.EDU> Subject: aluminum screen in homemade EZ masher I just constructed an EZ masher-type setup on my SS boil kettle from parts at the local Ace hardware. I used aluminum window screen as my filter. Have not used it yet but looks good and was cheap. Anyone ever have problems using window screen with a setup like this? It seems people usually look for a source of stainless steel screen or buy a SS Surescreen. I don't have problems using aluminum in my brewing so that's not an issue. After adding this spigot to the side of my kettle I thought that it would make a great bottling bucket. Just boil some water in the kettle for 20 minutes with lid on to heat sanitize.

Don't you think a homebrew shop would want to sell Yes! I know you'd rather sell the grain than have it come from somewhere else, and of course it affects the bottom line. > someone 2,000 lbs of grain?

It's not anything close to whining...it's real life business. First, there are precious few groups buying tons of grain through means other than home brew shops. Second the profit on 40 bags of grain is what? If you suggest they are saving $3 a bag, let's say that's half your profit. So you would have made $240 on that one buy -- assuming *ALL* those people would have purchased through your store had they not been able to buy elsewhere. If there's a brewpub in your vicinity, I doubt that you are/were the sole HB shop. And, if $240 it is the "make or break" level for your shop for the month, you're probably in trouble already. If, due to volumes, your margin is much lower than that, you're being disingenuous when you suggest that that's all that's being saved by the brewers, or you're selling at a loss anyway. If the problem *IS* so widespread that this form of competition (that's what it is, by the way: competition) is adversely affecting the bottom line, those in "real life business" take measures to counter. When a "real life business" finds itself non-competitively priced, a "real life business" would normally narrow it's margins to recoup the traffic, and accept that they just aren't going to make that much on that particular product, or they stop carrying it altogether. Like evolution, you adjust to the environment -- or you die. But, again, I sincerely doubt (and I'm repeating myself) that such dealings could be at the volume necessary to be the cause of the decline of home brew shops in general -- don't you agree? > How do you think a restaurant would do if you could bring > your own ingredients and just have them cook it? Same thing. I hope No. It's not. The correct analogy would be choosing between shopping at your local supermarket, or going to a warehouse club for your groceries. This is also "real life business," by the way, and home brew shops that are being burdened by low-cost competitors really could learn by looking at that model of competition. You'll NEVER stop someone from trying to get the lowest price on a purchase -- well, rarely, anyway -- particularly in mainstream US. The IDEA is to make your product or venue somehow more attractive to the consumer. Sitting back on your haunches and complaining about the competition certainly doesn't accomplish anything. > you'll be a little more sensitive to the issue and, if > you don't beleive what I'm saying, ask the owner of your local shop how > he/she feels about the topic. That might > educate you better than I ever could. OF COURSE they're passionate about it. They'd be idiots NOT to be. However, if they just sit back and cry about competition -- no matter the source, they're whining. If they react to it in such a way that they remain COMPETITIVE, they're treating their shops like "real life businesses." > > Cheers! > Marc Sedam > Chapel Hill, NC It's not my intention to offend Marc or any other shop owner/employee, but if EMOTION is the basis for your business decisions, you're destined to continue the rather frightening trend in the retail home brew community.
