I went back up to O'so yesterday to check on the barrels and install the sample port. It has already been 50 days since we brewed the lambic! Wow, time flies. However, when you consider the beer will have to age close to 2 years, that isn't much time at all. At this point in the game, it is more of a sensory check for off flavors. I am expecting it to taste/smell essentially like a berliner weisse. I was also curious if there would be any differences between the barrels. There are 14 barrels, so hopefully they will develop differently and we will have some diversity to blend with.
Drill a 7/64" hole and catch a sample
As expected, they all taste/smell like a berliner weisse, which is a good sign. We are on the right track. There wasn't a whole lot of variety (obviously it is still very young), but there was some. Some barrels were more lemongrass, some were more minerally, some were more brett/funky. Aside from tasting and smelling the beer, it is a good chance to take a gravity reading. All the barrels we tested were hovering around 5 brix (1.009 SG).
