BREWERS NOTES (for the original recipe)

This beer is extremely layered, when had young, the dried fruit/raisin from the Special B is prominent. Over time, the B blends very well and you are left with a nice roasty, coffee flavor that ends with dried fruit. Don’t fear the ~100 IBUs, they are needed to support this malt bill.

Aroma: (9/12) – Sweet malt, soft spicy hop aroma, chocolate with hints of roast

Appearance: (3/3) – Dense light tan head and garnet, nearly opaque

Flavor: (16/20) – Rich chocolate flavor not as bitter or as much hop flavor as I’d expect from 100 IBUs – well balanced for a big beer

Mouthfeel: (4/5) – Body is light for a beer of such strength, alcohol evident but restrained for the size of the beer

Overall Impression: (8/10) – Balance is good, flavors are well married, I would guess there is some age on this
Total: (40/50)

Stylistic Accuracy: 4 out of 5
Technical Merit: 4 out of 5
Intangibles: 4 out of 5
