I am doubling a recipe for a Munich Helles–the original makes 5.5 gallons. When I used the “scale” feature in BeerSmith the quantities of everything doubled (as expected) EXCEPT the hops. The original recipe used 31 grams at 4.0% AA. The scaled-up version uses 88 grams at 4.0%.
Is this normal? Is there a decrease in hops utilization that accounts for the need for additional quantities?
The recipe for the 5.5 gallon batch is pretty straight forward (150 mash):
10 lbs Pilsener (continental)
0.75 lbs Munich
0.25 lbs Melanoidin
31 g Hallertau at 4.0% for 18.1 IBU’s
I was expecting to just double everything–and I want to make sure I didn’t mess something up or forget to change something in BeerSmith.
