Is there any reason to boil longer than your first hop addition?
I made an extract wheat kit with 1oz of flavoring hops at 15 min, and 1 oz of bitter orange at 5 min for bittering. My propane tank was about done, so I knew I would never get a full hour of gas (I can't buy by the pound, so a refill is a flat $18). I shortened my boil to 20 min so that I would have some time to get things under control before the hop addition. Is there anything wrong with this?
