BARREL AGED! Yup, the longer, the better! As BCBA has Aged 10 Years, we thought it was appropriate to challenge brewers to age their beer as well! 2019 is the #yearofthebarrelaged. To register for the Brewers Challenge, please fill in our form and submit it no later than September 1st. NOTE: Only breweries that have been approved for a booth can submit a beer. Invitations sent May 17th.
