One thing that I find works well for extract brewing is: Boil the water first (see my other posts for why this is important in my environment) and let it cool. Then freeze it in the deep freezer. Boil the extract with not more than 60% of the final volume. Put the ice in the fermenter, pour the wort on top. One kg (or whatever unit of weight) of ice at -20<degrees>C (-4<degrees>F) will cool down 1.5 kg (or whatever) of boiling wort to 20<degrees>C (68<degrees>F). The only problem with this method is that the weights are pretty critical. Make the ratio 1:1 and the resultant wort is at 0<degrees>C (32<degrees>F). Make it 1:2 and the resultant wort is at 33<degrees>C (92<degrees>F). Greg - -- Finger grog at lemis.com for PGP public key. See complete headers for address and phone numbers.

I've only brewed a vanilla porter once before, a small 1 gallon tester batch. I used 1 vanilla bean. It was so sickly vanilla I had to throw it out. When I brew my 5 gallon batch, I plan on 2 beans. Thats 40% the amount of vanilla I used the last time, so it should be good. Maybe try 3 if you're daring, but 1 bean in 1 gallon made the beer undrinkable, at least to my tastebuds.

I have to rinse very well, and it has ruined some bottles of beer decanted from a keg for travel. I have rinse my fermenters, everything. I have used it to also sanitize some drinking bottles, and have found a very strong medicine taste upon drinking anything from the bottles without first rinsing it. It may be the Austin water, tho. I didn't find this problem in Dallas when I was living there and brewing. Just here. Dave (also in Austin) "You can't be a real country unless you have a beer and an airline.

Looks like the solution will be to first chill with water to remove most of the heat and then use cold water or glycol to chill further. The cold water or glycol can then also be used to control fermentation temperature. Regards Braam Return to table of contents

Date: Tue, 20 Jan 2004 07:44:46 -0500 From: "-S" <-s at adelphia.net> Subject: re: Brewing with Sugar, citrus vs cidery John Palmer says, >My first question is to Steve, you say there is an "obvious" difference >between table sugars made from beets vs. cane? Cane sugar (to my senses) has a clear molasses note. I don't detect this at all in say corn sugar or maltodextrin. I don't have enough experience with clearly identified beet sugar to give an opinion, but I've read in non-brewing sources that beet sugar has a bitter edge which makes it less desirable than cane in some applications. Beet molasses is too bitter for human consumption - which matches the story. My hunch is that despite some rather elaborate methods of refinement, the 5lb sack of granulated sugar from the grocer contains a little source flavor. Not much mind you - but it's detectable. I didn't say it mattered in beer, but the flavor/aroma is present. >When I was researching my Brewing With Sugars article recently, the >sugar industry web resources stated that table sugar is so highly >refined that there was no difference in taste between cane or beet >sources and I accepted that. Be interesting to verify that for myself. It would be interesting and educational. I'm pretty certain there is a detectable difference, but there may not be enough to matter compared to beer flavors. >Secondly, define citrusy flavors from high sucrose worts versus cidery >flavors. These are definitely different. I've never seen a definitive test, but I think it's pretty easy to understand where the cidery and wine-y flavors could come from in nutritionally deficient wort. Lack of FAN increases levels of organic acids, and fusels and the corresponding esters. This isn't the same as citrusy which implies sharply tart (yet not lactic or acetic). That's why I think Wes had misidentified the issue. Citrusy has always been uncommon and mysterious, but cidery is pretty well understood (at least by plausible yeast metabolism) and not uncommon at all if you use sugar adjunct. AlK in his book "Homebrewing Vol I", pp 285 talks about cidery flavor and de scribes his experiment. Al separately fermented three solutions of /table sugar(sucrose), /corn sugar(glucose) and /invert sugar. He notes that all three tasted cidery, the invert sugar most and the glucose sol'n least - but all three had the cider-y flavor. Al suggest that acetaldehyde may be involved in the cidery flavor and I don't discount this possibility. Anyway Al's test result flies in the face of Wes' comment that invert sugar can somehow prevent the cidery flavor. Al's experiment suggests the opposite, tho' I don't honestly believe that invert is any better or worse than sucrose. >I recently did a side by side brew where I had 3 Coopers Draught Ale >extract kits,[...] .... >The >Old kit made with 1 kg of extract had a pronounced apple >fruitiness to it, but not exactly cidery. Cooper's are LME as I recall. DME is pretty stable, but LME - not so much. That could certainly be a factor in strange flavors to old LME. Also I wouldn't necessarily expect all the necessary yeast nutrients to be stable in LME, maybe not DME either - who knows. -Steve Return to table of contents
Date: Tue, 20 Jan 2004 08:58:55 -0500 From: Randy Ricchi <rricchi at houghton.k12.mi.us> Subject: fusels I brewed a barley wine on Sunday; 5 gallons, split between two carboys, two different yeasts. I pitched a decent amount of slurry in each batch and oxygenated well. The room I'm fermenting them in gets fairly cool overnight (low 60's) so I put the two carboys together and wrapped them with a blanket. By Monday morning the airlocks were perking along at a pretty good clip. I pulled the blanket away for a peek Monday evening and there was a huge kraeusen in each carboy. I put the blanket back around them. This morning (Tuesday), I pulled the blanket back for another look and there was absolutely no kraeusen on one of the beers, and minimal kraeusen on the other. Since both airlocks were still perking away like mad, I thought "uh, oh.... excess fusels killed the head". I peeled the blanket off and left it off. I didn't have a thermometer tucked in there, but in feeling the sides of the carboys there was no "cool" feeling like you would normally have when touching glass in a 64-65 degree room. They must have been pretty warm. My assumption that it could be fusels that killed the head come from strong belgian ales I have brewed in the past that initially wouldn't hold a head, but after long ageing held a head beautifully. They were feremented warm, mid to upper 70's, and were high gravity beers. This has led me to a few questions that I know this group can help me with: Why is it that higher fermentation temps promote higher levels of fusel alcohols? Fusel alcohols are larger molecules than ethanol, right? Are fusel alcohols the same as fusel oils? I remember reading about esterification of higher alcohols over time, and have always wondered if that meant that the higher alcohols are broken down into smaller chained alcohols (ethanol, maybe?) and esters. Is this so? Are the esters created this way pleasant ones? Could that be why my belgians that initially didn't hold a head later held a beautiful, dense head after extended ageing? Ahhhh,,, nothing like fresh material to worry about :^) Thanks for any insights you can provide. Return to table of contents
Date: Tue, 20 Jan 2004 05:18:22 -0900 From: "Martin Brungard" <mabrungard at hotmail.com> Subject: Re: Vanilla Porter Question Don, You won't have too much vanilla with only two beans. I used two beans in a porter last year. I sliced and split the beans, then scraped out everything. All of that stuff, (skins, seeds, everything) was put into one of those White Labs yeast vials and then a good bourbon was added. I sealed up the vial and left that to infuse for a couple of weeks. I then dumped the entire contents into the secondary. The flavors were wonderful. The beer was a big hit with my clubmates. The only problem is that the vanilla and bourbon flavors are short-lived (2 to 3 months). I just had a bottle of that beer that was about 9 months old. It was still flavorful, but not as nice as when young. I might consider more vanilla beans next time, but they sure are expensive now. I'm hoping that others respond with their experience with vanilla extract additions. I used a Robust Porter as the base for my beer, just because I enjoy them more. But in retrospect, a Brown Porter base is probably more appropriate. My recipe used 10% chocolate malt and 1% roast barley. I might delete the roast entirely next time, or at least cut it to 1/2%. I would aim for the upper end of the bitterness range at 30 IBU's as you intend. The bourbon and vanilla lend a sweetness that needs the bittering to counter. Of course, hop aroma and flavor are not an objective for this beer. Martin Brungard Tallahassee, FL Return to table of contents

This must be a policy change that Jack made at some point in the not-too-distant past. I recall many posts and discussions in which he personally said that motorizing the mill voids his warranty. and such. I'm glad for this change, because my mill is motorized! And yes, it is well built and works well, and I don't think motorizing it is going to hurt it any. I was just re-stating what I've seen Jack post in the past. I wanted people to be aware of that. However, it now appears to be a non-issue. Great! Bill Return to table of contents

When I've been able to get fresh, well stored beans, I use 2 of them. I split them lengthwise, scrape out all the "gunk" in the middle, cut the pods into 1-2" pieces, and put the pods and gunk into the secondary for about a week. Lately, I've been reading about a worldwide shortage of vanilla and have only been able to find dried up, crunchy beans. My last try I used 4 of them (same prep method) for 3 weeks and was underwhelmed by the vanilla character in the beer. ------------>Denny - ------------------------------ Date: Mon, 19 Jan 2004 08:18:12 -0500 From: "Don Scholl" <dws at engineeringdimensions.com> Subject: Vanilla Porter Question Good morning, I just brewed a Brown Porter yesterday (Sunday) with approx. 30 IBU's and 5.5% ABV. I would like to add 2 vanilla beans cut into 1" long pieces and add to the secondary and rack the porter onto them for 2 weeks. My question is: Will this cause too strong a vanilla flavor or will I need to add more beans? Thanks in advance for your comments.

We seem to go to a lot of trouble to avoid hot side aeration, including the wort in the mash tun, but then sprinkle water in droplets into the tun: Could this process cause the sparge water to pick up additional oxygen and create more HAS than gently running the spurge water into the top of the mash ton without splashing or sprinkling?
