Brewing directly into wooden barrels

This past Monday 6/19/17 was the first time that we have ever brewed directly into barrels. In the past we've done primary in our stainless tanks & then transferred in wooden barrels.

The next morning I came in and the barrels were fermenting nicely. The idea of leaving barrel openings exposed made me uncomfortable so I added airlocks after filling the barrels. Both were filled with krausen & needed to be removed before being blown off.
