They seem to change Blackhouse recipe a few times, but I based this off a combination of the current grist shown on the Modern Times website and this recipe supposedly posted by MT themselves http://beersmithrecipes.com/viewrecipe/230943/black-house
Using Amber malt because Biscuit is not available and Victory is 3x as expensive.
Using a smaller percentage of regular Chocolate malt because I didn't have Pale Chocolate (would have done about 8% of the latter).
My Warrior hops said only 15.2%AA (default was 16.7) so I used a bit more
Wanted to use lower attenuation yeast to keep the FG higher (Blackhouse is 1018), happened to have WLP051 on hand. Would have used WLP001 otherwise.
BOTTLING UPDATE:
Tastes a it strongly of bitter coffee before adding coffee beans, so maybe use a smaller percentage of coffee malt next time. Bottled 3L without coffee, and racked another 8.5L or so onto 50g of whole beans (30g Sarutahiko's dark blend and 20g About Life's Ethiopia Heirloom).
