    Racked the beer from primary today. 58 gallons of beer into the barrel and 22 gallons into glass carboys. As for carrying over the slurry, well that decision was made for me. The host of the barrel took it upon himself to move the primary fermenters just before we arrived without telling me first. He isn't a homebrewer so he didn't realize this would disturb the trub and move a large portion of it back into the beer. So we wound up racking very cloudy 1.010 SG (from 1.068 OG) beer into the secondaries. It means we will have a couple of gallons less beer in the end, but it will also ensure plenty of bugs innoculate the barrel and that plenty of the bug farms wild sacc. yeast will make it in their to autolyze and provide a food source for the brett / bugs. It's a shame the abv is already up to 7.7% though, as this will slow down the development of the brett significantly. I guess we will be letting this one age in the barrel longer to compensate, provided the acetobacter doesn't get too out of hand!

    Sounds pretty interesting.

    Mine is still in primary from the 19th of April. Has a pretty funky, yet subtle lactic aroma to it already. Haven't tasted it at all. Pretty cloudy still, but plenty done with the main sach work. No pellicle, and sitting in a 75* garage.

    I plan to barrel it once I end up funking up the bourbon barrel I have right. Now.. Probably another 6 months before I barrel it. And will only keep it for a couple months before I pull it and let it chill out before I decide what to do with it.


    Did your beer in primary clear up at all? Mine's still pretty dang cloudy and orange looking.

    The one that got racked to the barrel + 4 carboys today (my homebrew club group project) was plenty cloudy because the trub got disturbed as mentioned above. My 3 carboys I have at home that have been on the yeast cake in primary for 7 weeks now are clear. Well 2 have been (and still are) on the yeast cake for 7 weeks now. 1 was taken off of the yeast cake after 6 weeks. I fermented them all at 68F for the first 3 days and then raised it up 2F per day until they were at 74F. Held them at 74F for the past 5 weeks. One carboy was fermented with french saison yeast and the bug farm was pitched 2 days later. The other 2 were fermented strictly with bug farm. I've tasted one of the strictly bug farm carboys, as I decided to rack it off of the yeast cake last week. It had a subtle lactic note and a noticeable brett quality. I'm going to leave the other strictly bug farm carboy on the yeast cake for the entire fermentation. This way I can compare a 1 year old bug farm on the yeast cake the whole time beer with a 1 year old on the yeast cake for 6 weeks, then in a secondary with no other additions for 46 weeks beer. I want to compare both the development and the flavor quality of the sourness/funkiness.

    Good stuff to note. I too was contemplating leaving it on the cake the whole time untill I rack to the barrel, or putting it in another better bottle with jut a tiny bit of the trub transferred. I didn't pitch anything extra, just strictly Bugfarm as well.

    So, to update it, I still haven't bothered to take a gravity reading, but mine sitting in primary still covered up and around 70*. It's FINALLY gotten a pellicle on the top. Small one with some large bubbles, but atleast I know it's doing it's thing. Took a taste of it the other week. It's funky for sure. The brett is doing some awesome stuff on it. Has some nice citrus to it, and getting sour for sure. No acetic notes to it, barely there on the finish. It's not quite as dry as I figured it would be, but it's pretty young. Only 2 months old I think.

    Pitched ECY01 as the sole yeast in this beer. I'm really wanting to break the pellicle and take a taste of it now.

    We topped off our barrel and took some initial taste test samples two days ago. We racked just 2 gallons into the barrel, topping it off completely. A small amount of pellicle was noticeable before topping off. The barrel was professionally reconditioned prior to being filled and is sitting in a 58F environment, so it appears that the evaporation is low and brett/bug development is slow.

    The three remaining gallons in the 5 gallon top off carboy were transferred into three 1 gallon glass jugs. Gravity of both the beer in the barrel and the beer in the donor carboy was at 1.004 (6 point drop since we racked into the barrel seven months ago) putting the abv at 8.4% and apparent attenuation at 93.7% now. That higher than desired abv isn't doing the brett any favors either. Sour development has barely started so I'm thinking this beer probably would be better to bottle in the fall rather than the spring. Fortunately the host is patient and willing to let the beer decide when it's ready. The three 1 gallon jugs will be the perfect amount of top off beer over that span of time.

    No acetobacter at this time, which was a plus! The samples from the barrel had a very tasty wine character. My project shareholders will be deciding between leaving the other 15 gallons in carboys plain, oaking them, or fruiting them. My vote would be to fruit them.

    Interesting info @koopa

    I recently tasted mine about 2-3 weeks ago.. It's very sour, not warhead sour, but getting close to perfect, IMO. The funk it out of control. Its really interesting. The sulfery smell is gone now, the pellicle is pretty much gone as well. Beer is still somewhat hazy/cloudy, but not that bad once it's in the test jar. Some patchy slicks on the top, but not a complete pellicle.

    1.006 gravity at the moment down from 1.059 OG.

    The beer is laden with citrusy, lemon notes, lactic acid, and a tiny, tiny bit of acetic acid to balance the funk a bit. Smells like a wet horse blanket/saddle, some cheese, and some earthy musty damp basement. Sounds unappealing to type it out, but it's pretty dang awesome. Has this white wine note to it, subtle, but has it in the nose. I've kept this culture pure, no dregs in it as well.

    I do have another sour going with almost all dregs, and some ECY14 saison yeast. It's got UNREAL white wine notes, and some intense sour notes from Wicked Weed dregs, and some Stillwater Brux dregs in it. 1.075 OG beer I expect to get bone dry, so it's not really thought out, as the abv might be too high for my liking. Might be worth blending it back with a lesser/table strength saison, getting it to 1.000 if I can, so the bug won't have too much to work

    I'm thinking that what has been holding our barrel project back (sour and funk wise) is a combination of the high ABV (1.068 SG) and the cold conditioning temperature (58F - 60F). I'd be curious to know what temperature your beer has been conditioning at @FATC1TY ?

    Now my 30 gallons of wild I brewed at home in May and have at home in carboys haven't been sampled at all yet. No idea on taste, funk development, acid development, or even FG at this time. I am curious to see if they have more acidity than the barrel project beer. I would assume they do. The basement that they are in does endure temperature swings (60F-80F) throughout the year. They also had a much lower SG (1.052) than the 85 gallon batch I did with my homebrew club (1.068).

    These two different batches also had different fermentation temps. The barrel project was primary fermented warmer. It was pitched @ 68F and fermented the first week @ 70F - 75F before being conditioned for the past 31 weeks @ 58F - 60F. The homebrews were pitched @ 64F and allowed to free rise up to the lower 70's and then held in the lower 70's as fermentation slowed down over the course of 7 days. They were then allowed to condition at room temperature for the past 28 weeks. So they probably conditioned around 65F - 70F for May and June, 75F - 80F for July and August, 70F for September and October, and btw 65F and 60F for November and December.

    Fermented it cool, around 65-68 controlled for two weeks, and then left ambient in the garage for a couple month, during the summer heat, I moved it inside, so it sat around 70* for the most part.

    It's stored now in my laundry room, which when the door is closed, that room will get at night pretty warm, probably around 73-75 at the highest since it's in a small laundry room with one vent. So I would venture to say, again, probably around 70 consistently.

    Quick update while It's on my mind..

    The ECY01 I did, is still in primary, hasnt been moved or messed with much other than helping the temp out a little.

    It's coming up on one year, within a week or two I think as well.

    Took a sample today as I'm anxious to get it packaged or moved to whatever the plans are.

    Beer was pretty clear, has a white-ish pellicle still on the top, but pretty much broken up and rafty looking. Crystal clear blonde hay colored beer under it though.

    pH of the sample was done @20*C and was 3.36. Not quite as low as I would have expected, but pretty low.

    Beer has some nice funk in the nose still, much tamer than the update a couple months ago. Very earthy, slight citrusy, lemon smell. No real acetic notes I can pick up.

    Taste was pretty tame as well. Perhaps my allergies are kickin in, but I didn't feel the pH matched the sour taste. Beer was obviously sour, but a very smooth, balanced, almost blended sourness, instead of a warhead upfront citric sour note. Funk was again.. there, but minimal. Pretty spot on for an unblended lambic I'd guess, and one at 12 months of age. My notes from the last check, had it pretty sour, so I think it's my tastes at this point.

    Impressed, but has somewhat higher hopes for it at this point. It's still young. Gravity is at 1.002 I think it was, was the same when I check it around the middle of Feb.

    Debating what to do with it now. I want to drink it and bottle it up.. Leave it as is, and let some bottles age away.

    I have a very young sour saison that used some dregs and some commercial bugs that is at a slightly lower pH, and it's a great candidate for peaches in a couple weeks!

    Also- have a YeastBay Melange and ToD and Black Angel dregged sour stout that I just measured the pH of, it's been brewed since Oct I think, and it's at 3.02 pH @ 20*C. It's VERY sour, and you can smell it even along with some great cherry pie and roasted notes.
