SARA just recently, 6-8 months ago(?), started printing batch numbers on the labels. Almost anything before that, there's no real way to tell with the exception of a few bottles. More info: http://www.beeradvocate.com/community/threads/sara-bottles.246746/
Been picking up SARA bottles since moving up here in January. I don't have any bottling dates on the latest Bernice, Lady in Grey, Hoeybier, Meh!, or West Ashley
Does anyone have details on more recent batches (release dates + corresponding batch numbers)? Say from Batch 8 to present.
