Date: Fri, 09 Jan 2004 22:22:47 -0800 From: Robert Marshall <robertjm at hockeyhockeyhockey.com> Subject: adding yeast at bottling, or not? Liquid or dry? Hi all, Since this is my first post after the New Year I wish wish everyone a most joyous year to come! I noticed someone posted a msg in the last couple of days where they said they always add dry yeast at bottling time and I wondered to myself how many brewers actually do that with their homebrew? The reason I ask is that I've noticed that many of my beers seem to take an innordinate amount of time to carbonate, and usually have a somewhat "tang" of corn sugar flavor (which is what I use to bottle condition). If you do use dry yeast, do you simply pour it in the beer prior to bottling, or do you reconsitute it in some sterile wort and then add it that way? If the latter, would it be more beneficial to use a liquid yeast rathr than a dry yeast? That way, I could also use the same strain as I brewed with. Thoughts? Robert Return to table of contents

Will let you know how it goes. I've tried it both ways. Boiled and cooled, siphoned then pressure canned. Then I tried just runoff, heat to boiling and pressure can. The amount of trub is larger in the batches where I just sparge, heat to boiling and can, but not by much, and the color of the wort is much less caramelized in the batches that are only sparged as opposed to boiled and cooled. Also you can get quite a bit of starters if you make a normal batch size, since I generally run off 7 gallons for a 5 gallon batch. Since you will NEVER have a pressure canned starter without the trub, I just decant into a new container and go. Cheers, Mike www.ipass.net/mpdixon/ Return to table of contents
Date: Sat, 10 Jan 2004 09:24:31 -0500 From: "David Houseman" <david.houseman at verizon.net> Subject: RE: creating clear canned wort While I sometimes have to create a starter from DME, I usually just use the wort from my brewing sessions. After filling my kettle, there's always some extra wort in the mash tun, the second runnings (or dregs, depending on your perspective). You can even add additional sparge water to the mash tun for a batch sparge to get some second runnings. This I'll collect in a separate kettle and boil, sometimes with just a little hops, to create start wort. This is canned or refrigerated, depending on when I expect to use it. The style isn't important for the starter. There's lots of "free" starter wort available. Dave Houseman Return to table of contents
Date: Sat, 10 Jan 2004 10:50:10 -0700 From: "Dave Draper" <david at draper.name> Subject: Bottling Dear Friends, With the recent commentary on priming amounts for small numbers of bottling, and general bottle priming as well, I thought I'd mention my old article (coauthored with Mark Hibberd) on priming bottled beer that appeared in the July/August 1996 issue of Brewing Techniques. A somewhat less wordy version of it is still to be found on my beer page (URL below). Not trying to toot my horn or anything, it's just another perspective on the subject. Speaking of BT, I'm sad to say that I no longer own a copy of the issue my piece appeared in. I lent it to a brewer at my local Rock Bottom back in north Texas (he used to give me big slugs of yeast from his fermenters for me to use), and never got around to collecting it before I moved from there, and have lost touch since. Anybody out there with that issue, a scanner, and Adobe Acrobat who would take pity on my pathetic plight and scan me the article in pdf form and email it?

Date: Sat, 10 Jan 2004 13:24:32 -0600 From: "PAUL SMITH" <pksmith_morin1 at msn.com> Subject: Starter trub Personally, I've never had a problem. The tremendous pressure of the p.c. generates a very clear break, the trub settles out to the bottom of my quart ball jars, and I have brilliantly clear wort above. I sanitize the lids and rims of the jars at each starter step, and nothing but this clear wort goes into my fermentor. I crash cool my yeast at the end of the final pre-batch step, and draw off the (now, beer) anyway. Good to be back. Been away for quite some time.

Date: Sat, 10 Jan 2004 15:06:18 -0600 From: Michael Grice <grice at binc.net> Subject: Starter wort/bulk aging Raj asks for opinions about aging in bulk versus aging in bottles. For beer, the one clear advantage to aging in bulk is consistency of flavor. For beer bulk aged in a carboy or keg, aging should affect all of the beer in the container in the same way. All of the beer is under more or less the same conditions. Any variations in conditions are eliminated (or at least vastly reduced) by diffusion. Each bottled beer, on the other hand, will age independently of the other bottles depending on storage conditions. Depending on your bottling technique, each bottle may not be the same. For instance, depending on your technique you may have slight variations in the amount of yeast, trub, priming sugar and oxygen in each bottle. Differences in storage may be minor, or they may be pretty significant. For a beer which undergoes extensive aging, this may mean that your finished product will have a lot of variation. *********************************************** As for clear, canned starter worts, I kicked around a couple of ideas without thinking of anything useful. For instance, running the starter wort through a coffee filter after boiling might work (and I do stress the word "might"), but it's more work and is a pain to sanitize. I liked Jeremy's idea about adding enzymes, although it had its drawbacks. Then there's washing the starter yeast, or doing a mash with an extended protein rest solely for starter work... So I asked myself what the real problem is. Eliminating potential off flavors from trub, right? So perhaps if you concentrated on getting rid of the trub before it can introduce off flavors in the beer you'd be better off. My thinking is that you can reduce the risk of off flavors from all trub by: 1. Decanting the starter beer off of the yeast prior to pitching 2. Racking the wort into a second fermenter a few hours after pitching Let's say that 10% of a liter starter is trub. That's 100 mL. It's not at all difficult to get at least that much trub into the fermenter after the boil. I'm sure I usually have much more trub that that, although I hope most of it is cold break. So by letting the wort settle after pitching the yeast and then carefully racking it into another fermenter, you can reduce the amount of all the trub in the beer at the same time. Will this eliminate the problem? Probably not, but I think it's a nice compromise between too much trub in the wort and the amount of work required. This is an area you could easily run into the law of diminishing returns. Michael Middleton Return to table of contents

Date: Sun, 11 Jan 2004 23:02:11 +1100 From: "Phil Yates" <phil.yates at bigpond.com> Subject: Snorer's Stout Just recently, I've taken to knocking off a few bottles of stout of an evening prior to dinner. I haven't made a stout for myself for a long time and the commercial one I rather like is Sheaf Stout. Jill complains that every night I do this, I snore very badly (is this opposed to snoring very well?). She says I have a problem and has threatened to have my nose drilled out, or whatever horrid things are done in the much talked about snoring operation. I tell her I'm not the one with the problem! My snoring doesn't bother me in the least. I'm not even convinced it is me rather than the cat who sleeps religiously with me on such nights in the spare room. But what can be causing this? Does anyone else suffer this problem? I haven't yet told Jill the stout I'm drinking is around 6.8% Alc by volume. I suspect it is the alcohol content rather than having anything to do with the colour of the beer. What is it about alcohol consumption that exasperates snoring propensities in middle aged old farts like me? There must be a scientific reason. Phil p.s. thanks, but no thanks Wes. I aint putting my arm down the "S" bend after you told me the Wollondilly Water Frog has sharp teeth and an aggressive disposition.

There is a school of >thought that this is one of the factors that leads to "citrusy flavours" in >high sugar adjunct brewing. That's about the most extreme case to be made in favor of invert sugar in fermentation ... and it's very weak. Yeast normally will produce prodigious and effective amounts of invertase. Getting yeast to handle sucrose is rarely more difficult than getting them to tackle other sugar adjuncts. In winemaking chaptalizing with sucrose is common and tests reveal no differences as compared to fructose & glucose additions. There is no credible evidence beyond speculation that fermentation of sucrose causes any greater extent of "citrusy flavor" than the fermentation of the component glucose and fructose. I've attempted to produce the citrus flavor by fermenting separate sucrose, glucose and fructose solutions - with no luck in any case. Other speculation include infection and the low nutrient environment of high sugar-adjunct wort as the cause. High sugar, and therefore low amino acid, worts will cause yeast to produce more organic acids and this may be a causative factor. == > ... candi sugar ... boiling the sugar with some citric acid. > We have an oxymoron here - candi sugar is crystalline sugar, invert sugar > is exactly the opposite as outlined above. What Graham has outlined is fine > - just skip the citric acid and you will certainly be able to produce a > more interesting sucrose solution. I agree that candi is re-crystallized sucrose, and inverting the sugar will prevent the traditional recrystallization process - but I can't see that it makes any difference to flavor. The flavor and color of candi are primarily due to caramelization and to a lesser extent ... >it is made from the roots of the Sugar >Beet and Chicory plants. It is a "pure" sucrose product but for what ever >reason, does not seem to throw the same flavours as cane sugar I don't have much experience with sugar from beets, but there are commercial amounts grown in the US and esp Europe and both the US and most of Europe have some impressive barriers to free trade in sugar. Of course the vast majority of sugar in the US, and almost certainly in Wes' Oz are from native sugar cane. Sugar beets and chicory (that's a new one on me) are cold-climate sources of sugar and are grown in places like France, Belgium and Germany, as well as the central USA. What is (or should be) obvious is that "pure" sugar is a relative term. Common cane based white granulated sugar smells a *lot* like molasses. Try sniffing a closed container of white sugar upon opening - it's dead obvious. Date sugar also has a characteristic smell. Beet sugar is said to have a noticeable bitter background flavor from the beets. No experience with chicory root sugar, but of course it's not traditional - a recent new use for chicory. Brewers with a much greater interest in tradition than I have should probably examine the common sources of sugar in Belgium around the time that candi sugar came into brewing use. It's a good bet that it was from sugar cane of the West Indies. Beet sugar was first prepared in 1747 by a German chemist, but wasn't commonly used till the Brits blockaded French ports during the Napoleanic wars, 1793-1815. It wasn't till ~1880 that beet sugar took dominance over imported cane sugar. Westmalle has been making beer since the early 19th century so ...

This is something close to >5-10% of the volume of the liquid in the canning jars. That is an >unacceptably high level to me. I disagree with your reading of the lit Rob. There are argument both in favor and against allowing much break material into the main FERMENTATION. That's a bit different than for the starter. There's no doubt that pressure canning precipitates a lot more hot & cold break, and in a canning process there is no way to eliminate this until the jar is opened. The break material consists of coagulated protein and phenolic materials, a large fraction of the minor metal ions of the wort (Zn, Cu, Fe, ... ) and a lot of the malt (and hops if used) lipids. The yeast are quite happy to have the break present as it acts as a nucleation sites for CO2 removal, yeast use the metal ions as required co-enzyme factors, and use the trapped lipids for cell nutrition. There are several papers documenting the yeasts use of break. Of course late in the main fermentation you don't want excess lipids hanging around. The best course seems to be one practiced in some German breweries of removing break a day or two into the main fermentation. >2) Decant to another container. > [..] >If I must sanitize another container (which >then must ALSO be cleaned afterwards) to make a starter, [..] I think you missed the turn. Store the started in the canning jar break and all, and decant (pour off the clear top fluid) into your starter-vessel. You certainly aren't going to make a starter in a canning jar, are you ? >So I am still searching for a solution to reduce the amount of trub in my >canned starters. ==== Jeremy Bergsman adds, >If you were to spend a >great deal of time and money you could probably work out a >way to digest the protein with good enzymes Unlikely as the proteins are denatured and not very susceptible to enzymatic degradation. >2) use laboratory media.

I use YPM which is >IIRC 2% peptone, 1% yeast extract, and 2% maltose. This stuff is expensive. Jeremy - I'd like to invite you and Rob to a meeting of Anal Brewer's Anonymous at my place next Wednesday (I'm on step 9). Spending $10 a quart to get clear starter media is more than a little silly. === My sincere advice is to store the canned wort break and all. If you feel the need for emotional reasons, you can leave some of the break in the canning jar when you pour it off - decant - but it's really not required. It's a good idea in any case to transfer & decant your starter while the fermentation is active since this collects the live in-suspension cells and leaves behind dead cells and trub. If you think break from a starter is "too much" you should collect 5gal of your freshly cooled unpitched wort and chill it well for a few days at near freezing as I have done. The amount of cold break that accumulates is impressive. Most folks with in-line CFC chillers never remove this huge load of cold break unless they rack/decant. -S Return to table of contents

Date: Sun, 11 Jan 2004 20:04:20 -0500 From: "-S" <-s at adelphia.net> Subject: coffee, caffeine, home roasting ! Bob Hall, Spencer Thomas and Alexandre Enkerli all interested in home coffee roasting ! Well add another to the list - I started roasting a couple months ago. I have to say that the coffee roasting methods aren't particularly similar to malt roasting, Alexandre's comments aside. The roasting temps for coffee are higher and roasting times (<20 minutes) notably brief. Spencer's comments about the use of PIDs and advanced methods for home coffee roasting considerable overstates the case I think. Home coffee roasting technology is in serious need of the sort of innovation and ingenuity that HBD has provided to HBers. A hot air popcorn popper as coffee roaster is sufficient to make about 2 pots of coffee per run - a toy system IMO. No one even discusses the background knowledge in enough detail to make any sense. There are vague discussions of the dreaded "baked" flavors from too-long roasting, but little interest in understanding what's really happening. Well by Monday I'll have my hands on a copy of Sivetz "Coffee Technology" - (think M&BS but written by a guy as opinionated any HBDer). Is a 'Home Coffee Roasting Digest' possible ? I'd certainly enjoy it. The Sweet Maria's list is decent but has commercial restrictions(no dissing the vendor) and rejects nearly all of my email addresses as a non-customer. CoffeeGeek is a great place to read user reviews too. Coffee isn't about to replace beer in my list of beverages, but it's has some advantages. -S Return to table of contents
