Is Sam Adams changing the rules this time?
On the site they say they will choose 2 grand prize winners and possibly brew those beers. This years had three winners.
They say that any employee of the Boston Brewing Co. is ineligible. The brewer of the wheat in this years contest is an employee.
Lastly, they say to keep the OGs of the ales below 1.068, the old ale with 10.6% ABV must have been higher than that.
