We produce a number of beers derived in vessel, most are brite-tank additions to a parent beer (e.g. flavours, hop extracts). Currently it seems the only way to convert to a “Derived in vessel” batch is by transferring and splitting a batch - typically we don’t do this, we transfer the entire batch to the brite tank, package half of it as the parent beer, then make additions to convert to the derived beer for the remainder.
Is there any way to convert to the derived beer without transferring? Currently it seems the only way is to tell breww we’re transferring back to a fermenter then back into the brite.
