Opus 18: My Bonnie’s Scottish Heavy

Posted: May 31, 2013 in Recipes

Today was one for the wife. She is a big fan of Scottish-style ales, so I created this recipe more for her than me. Brewing hint: Keep the wife happy! I’m hoping to enter this one in a competition or two, and I’ll probably sample a few, but most of them will go to her.

This recipe is a direct ripoff of Jamil’s NHC winning recipe, and is technically a Scottish Export 80 or Scottish Heavy. No jokes there, please.

The name comes from one of the most popular Scottish folk songs, and is my first “song specific” name. I took the “love song” interpretation, where Bonnie is his love (not the exiled prince).
