Hi All… I am working on a Negra Medelo Clone. I am using the recipe from CloneBrews and ran into a couple of questions. After inputing the recipe into BeerSmith my SRM is coming out at 11.6. The book lists the SRM at 21, which seems about right. If I were close it wouldn’t be a big deal but that seems fairly sizable. I did change it to all-grain and adjusted for my efficiency. I am worried if I just start increasing the specialty grains it will throw the flavor off.
My second question: it asks for Hallertau Hersbrucker which is a little tough for me to find. I’ve been told that I can replace with either Hallertauer or Hallertaeuer Mittelfrueh. Just a general question, what are the flavor differences between these?
Lastly, it calls for Wyeast Bohemian Lager, which last time I used it was also tough to get. I guess I could order it but could I just use Southern or Northern German Larger or maybe Bock yeast.
Here is the recipe (including my adjustments):
Est OG- 1.050
8.75 lbs German Pilsner (2 row)
2 lbs Vienna
6 oz Caramel 60L
4 oz Caravienne Malt
2 oz Chocolate Malt
