So, I'm reading conflicting info on FWH. Some say, don't count FWH as bittering hops, count them as 20 minute additions, others say they count as bittering in IBU's. So, do I FWH and do a 60 minute addition??
I FWH more often then not just because I think it gives a slight bit of added complexity to the finished brew. You get a little bit different oil extraction from the hop at a lower temp then in the boil. I usually account for about an added 5 IBU in a FWH tossing them in after my first runnings are complete and I start my sparge. Just adding 20 minutes of boil time for a calculation for FWH is going to cut you short for your actual bitter units you'll achieve.
