So hop utilization is increased when you keep half of the LME out until the last 15 min of the boil.
Is there a good way to figure out how recipes using this method?
None of the hop calculators I use have LME additions built in and to make it harder I'm only boiling 3.5 gallons out of a 7 gallon batch.
Here is what I playing at: Using brewer's friend IBU calc, 3.5 gallon boil for a 7 gallon batch. Est. OG .063. When I boil all the LME for 60 min I need to use 1.5 oz of bittering. If I save half of the LME until the last 15 min and thereby cut the estimated OG to around half ( .035 is what I typed into the calc) then I only need to use 1 oz.
Does that sound about right?
