I don't have inside information. They made 10,540 bbls last year. Is that enough to cover the East Coast?
That's 326,740 gallons of beer ( 31 gallons per barrel). 40,842 pints. You never know, though. Beer distribution is weird.
Almost assured it will be further distributed than it is currently. OB didn't purchase them to keep them small fish. Their location is massive and I'm sure they'll be able to significantly increase production if that is their desire.
Right now Perrin is primarily distributed only as kegs and only in Michigan. I imagine they'll get to more packaged distribution now, but east coast is probably several years off.
