In order to purchase a 4-pack of KBS, I had to purchase any case of Founders, which in turn would lead to more Founders sold, possibility of getting more special releases in the future, etc... I went with the variety of the Porter, Dirty Bastard, Centennial, and Pale Ale. Case was packaged on 2-20-13, not the freshest, but if I was going to get KBS, I went with the cheapest avenue. Anyway, Centennial bottled on 2-14-13 and still had some good hoppiness to it. Porter bottled 2-14-13, and no date on the DB. When I went to check the bottle date on the Pale Ale, it was dated 12-31-12. Drinking it now and can't believe that Founders didn't have any other Pales Ales lying around the brewery to throw into the variety case that weren't over a month old. Do breweries just throw variety cases together by looking at inventory and seeing what needs to go? Has anyone else seen this practice or experienced this with other variety cases besides Founders?
