Made this today:
5lb Pils
5lb Munich
1lb C-60
1 oz Cascade (6.6% AA, pellets) FWH
1 oz Magnum (12.8% AA, pellets), 90-min boil
2 oz Mosaic (12.3% AA, pellets): 1 oz for @10min, then 0.5 oz @ both 5 min and flameout
US-05 will handle the heavy lifting in the primary.
Beersmith2 says this one should weigh in at ~1.060 and ~80 IBUs in Beersmith 2.
That said, as smooth as Magnum and Mosaic are to my palate, I don't expect the final product to be as crushingly-bitter as the 80 IBUs might imply.
Will know in about a month.
