Just picked up a few Templeton Rye and JD barrels from Boulevard. These barrels are seconds and were just dumped a few days ago with a beer Boulevard has done. There are no whiskey notes left in these barrels. So this shouldn't be an issue. Barrels are in great shape and smell wonderful. I'm looking for some ideas and twists on what to age in these. Of course these are going to be Wild Beer barrels. Were thinking for a first run in two of the barrels will be a Old World Porter and a Oid Bruin. If anyone has ever had the opportunity to sample New Glarus Old World Porter, then that is where our inspiration comes from. Does anyone have any other ideas on styles? They dont have to be a specified style by any means. It can have a fun twist of ingredients too. For example our current barrel is full of a BGS that used 1388 in primary then dosed with Brett B in the barrel. Something fun and exciting, but different.Lets have fun here!
No one has brought it up yet, so I thought that I would interject that Oud Bruins are made in stainless conicals in order to keep the bugs somewhat at bay by choking out their O2 that in a barrel would be readily available. I think it would be a stretch in the traditional sense to call it an Oud Bruin, since from the barrel it would be a lot more similar to Flanders Red. Either way, I am certainly not big on style guidelines, but from a practical flavor development perspective, the barrel would make it difficult to impossible to get where you would to be for a Bruin. Still would be effing awesome beer though.
Saboteur is a tasty beer, very much a hybrid sour style. I'm also liking the idea of a BW, although we'd have to brew it higher gravity I suppose, so it can hold up in the barrel. We're not looking to fit into any style guidelines here, so a 5% BW is a definite possibility. Saison with brett, how can you go wrong there. Good ideas folks 
Again, I am not big on style, but the real beauty in BW is that it is brewed to a very low alcohol and consumed quite freshly. Not that you couldn't brew a bigger version, but the balance of the flavor profile and its cloud-like lightness would be sacrificed.I am in the early stages of planning for a gueze project, so immediately when I saw the multiple barrels, that is what I thought of. Stemming from that idea, is the beauty of the fact that no matter what you ferment in them, you have the opportunity to do all sorts of blending. Perhaps that could be your basis for recipe formulation. Three beers that could be the perfect menage a trois. If that is not what you are looking for, I really like the Petrus Aged Pale. I have been wanting to tackle something like that since the monster Flanders thread over on the GB.
