Made this a couple of days ago: (a riff on Great Lakes' Dortmunder Gold, a staple in my beer fridge)
5lb pils
5lb munich
0.5lb C-60
0.5lb wheat
Cascade (9% AA, whole), to 26 IBU's (bittering)
Mt Hood (6.5% AA, whole), for 6 IBU's (10-min addition)
Mt Hood (6.5% AA, whole) for 3 IBU's (1-min addition)
34/70 will handle the heavy lifting in the primary.
Beersmith 2 told me this would weigh in at ~1.060 for 5.5 gallons in the primary, 35 IBU's, and ~9 SRM.
Will know in about 6 weeks how close i got to GLBC.
