I suggest you do the same simple experiment I did: Dissolve 10g of brown candi in 100 ml water and compare the resulting colour to a known beer (you'll probably have to dilute the sugar solution). The different makes of candi I've tested give colours 2 to 6 times darker than de Koninck: that means in the 40-120 EBC range (something like 60-200L). > I believe that the dark sugar > *does* provide a specific flavor contribution, although it may be > slight, but haven't had the opportunity to do a control. There is a flavour effect but that's not the only reason to add Candi. The amounts found in some Belgian beers have a strong effect on final gravity, body and mouthfeel: I expect an all-malt version of say Rochefort 10, coloured with only caramel malts, would serve better as pancake syrup. > I think that > sensitive, judicious use of Belgian caramel malts (and especially > Special B) is far more critical.

As many people have noted, there are now two brands of Belgian malts on the U.S. market. Interbrew's DeWolf-Cosyns varieties are possibly the best known, though the second brand, known cryptically as HDM, has (in my experience) also proved to be a nice performer. Thanks to a kind correspondant in Belgium, I've confirmed that this malt comes from the Descamp maltings. Here's a slice of his message: >I have a rather good knowledge of HDM (Huis Descamp Malting). The house is >in Gembloux (between Namur and Ottignies). A part of the production is made >in Bruges.

In fact, it seems possible >that a Danish [firm will] purchase HDM (a strategic bankruptcy, perhaps). I can personally attest that they have a very modern facility (recently rebuilt, as stated above), though the facade of the building is protected under a historic easement, and looks about the way a maltery would look in, say 1930s Belgium. Gembloux is also home to an agriculture school, roughly the Belgian equivalent of Texas A&M. ------------------------------ Date: Wed, 02 Mar 94 10:07:35 -0400 From: "Phillip Seitz" Subject: Re: Lambic Digest #290 (March 02, 1994) David Berg notes: >Last night I cracked open a bottle of Liefman's Goudenband.

During a tour of the brewery we were told that all the Liefmans products are filtered, sweetened, and force carbonated. I tend to believe this, as the samples we had from the fermenters were MUCH more sour than the finished product. That wouldn't bode well for your yeast culture. On the other hand, nobody should trust the information on these tours 100%, so..... ------------------------------ Date: Wed, 2 Mar 94 10:14 CST From: korz at iepubj.att.com Subject: Westmalle Yeast + McFarland Norman writes: >flavor black malt) and got a rousing fermentation going this morning >from the Westmalle yeast I used. This brew was actually the second Have you had success with this yeast in the past? I've read that they use a bottling yeast which is very unattenuative. Did you get the yeast from a bottle or did you get it from the brewery? On a releated note, my cousin and I tasted some hand-carried Westmalle Dubbel (from the Netherlands) yesterday, and it had a perfumy nose that I did not notice in Imported bottles. It was brought over perhaps 9 months ago, but was "best by" dated: 220295 and kept at 54F all nine months. The flavor was the same, but the nose was definately fresher than what we get here. Finally, has anyone ever tasted McFarland Golden Fire or McFarland Red Beer? The Red was okay, but the Golden Fire, I would say, was roughly in the Belgian Abbey Ale style. A bit weaker in both nose and palate, but resembling St. Sebastians (sp?) Abbey (Crock) Ale. Both beers tasted very Belgian. Now here are the kickers: 1. Jackson says they are bottom fermented. 2. they are brewed in Italy! 3. they are brewed by Birra Dreher! Yes, that's the brewery founded by Anton Dreher, originator of the Vienna style of beer. I'll bet that Anton Dreher is spinning in his grave from the levels of higher alcohols and wacky esters in these beers. Ironic.

Yes indeed, go to a place that has horses. Preferably in warm weather. Watch the horses run. Wait for a sweaty horse to come by. Breath. Go to the stables. Watch them brush off the sweat with a big window-cleaner type thingy. Breath again. That is horsey. Watch out for the green-head (ie. horse) flies! And watch your step.

According to Guinard, % the enterics (and, btw, E. coli is not one of the enterics listed by % Guinard) take over first, and are subdued by the yeasts. In a batch I % brewed last spring the enterics took over, but were not only not inhibited % by the yeast, they actually kept growing to the extent that there was a % SECOND KRAEUSEN from bacterial activity weeks after the yeast had gone % dormant. Guinard does not mention E. coli but the dissertation and papers from Leuven do. It is indeed possible tha enterics can take over but if one follows the course of things one could concievably add an extra dose of pedio and brett to really kill off the critters. But I think you make a very important point about the natural course of things. If guinard had his way he would have never written anything about recipes but the AHA expects such things from the book series. % I was making an example. To elaborate, botulism is a toxin % produced by bacteria. The bacteria need not be present for the food to % kill you. That's why you can get botulism from cooked food. The moral % being that faith in the "Nothing pathogenic can live in beer" does not % guarrantee that something yucky can easily spoil your p-Lambic. A good % Hafnia infestation, if allowed to survive too long will take your DMS % levels through the roof. This is correct but if I recall correctly the other organisms reduce the DMS over time to insognificant levels. But this is on the order of two years. % Aha. The microflora in your kitchen/backyard are immensely % different from those in the attic of a lambic brewery. Your kitchen is % full of not only enteric and other vbacteria, but Penicilium spores and % scores of other moulds and weird things. The attics of Lambic breweries % have been selectively breeding certain bacteria (and bats) for generations. % You are right. Here in arizona we have various pigmented forms and staph floating around according to a air quality guy I spoke to. As well as yeasts and molds. So yes my brewery is not like a blegians. But Boon is in a relatively new place and the air and the all important cask provide the microflora. % It is worth trying. It has been tried before, and will be again. % I feel though that it IS something to worry about, and if one is truly % serious about making a decent p-Lambic, they should read up and understand % what they are doing. You have obviously done your homework, except I still % stick to my original comment which was that E. coli in your wort should not % be taken with a cavalier attitude. This is not because it may show up in % the finnished product after two years in the bottle. It may not only % produce off-flavours, but may survive long enough in the fermenting wort to % cause serious illness if a sample is taken at say, 2-3 months. There are a % gazillion strains of E. coli, and some are very unpleasant indeed. An excellent point. I would plan to micorscopically test the wort first prior to tasting I think. Has anyone out there ever cooled the wort overnight and then tasted it at 2-3 months and gotten sick? Enquring minds want to know? And aren't E. coli relatively intolerant to low pH and alcohol over 2%?

I'm extremely happy with the Wyeast Belgian White strain, but I just ordered the "Belgian Wheat" strain from Brewer's Resource (disclaimer...). Has anyone else out there experimented with this strain? Is this just recultured Hoegaarten sediment? Also, I recently got and read the "Belgian Ales". Good reading, but has anyone else out there noticed the striking similarities between Lambic/Geuze and Wit Bier? I find it remarkable. It seems that they could have even been the same thing some time ago, then diverged in the recent future. (I'm refering to the brewing process and the common element of spontaneous fermentation). Finally, where can I get a copy of "Les Memoires du Jef Lambic"? My francais is pretty good, and I'd like to get the original French.
