I have not long started BIABing, and have cubed both brews done so far. Advice I had was much the same, but to knock 20 mins off all additions - bittering hops at 40 min, 20 min hops at flame-out, later additions to cube. So that is what I have done. Unfortunately, I can't accurately tell you what the outcome has been - first proper taste of brew #1 is slated for tonight - but both brews ave tasted fabbo out of the fermenter. (And I can't wait
)
There are other guys who will tell you just to hop normally, and keep the boil down to more of a simmer to keep the volatile hop oils from boiling off.
The long and short - as it seems with most homebrewing questions - no definitive answer....
