My recipe is as follows:
12 lb. pils
1 lb. caramunich
1 lb. vienna
.75 lb. special b
1.5 oz Goldings @60
1 oz. saaz @ 10
1.5 lb. Dark candi syrup (not hard sugar-huge difference)
Yeast is up to you. I used the WLP550 for this. Just a sample tonight while bottleing was dark fruit, vanilla, the special b came through fairly well so there's a good amount of caramel in there, and the yeast profile really rounds it all out. 3 months in a bottle and this will be one of the best things I've made.
