So I'm planning on brewing a MiaBock this weekend. I was looking at this recipe.
10 Gal 70% efficiency
27 lbs Vienna
1 lb of Carmel Pils
2 oz Hallertauer Tradition 50mins
2 oz Hallertauer Hersbrucker 10 mins
2 oz Hallertauer Hersbrucker 5 mins
2 oz Something maybe MT Hood Dry Hop
Bohemian Lager
Problem is despite needing Vienna I got Munich instead. So will Munich work or should I go back and get the Vienna?
