"If I were you I'd drop the Indian/Peruvian coffee idea. Indian coffee is mostly cheap robusta AFAIK, and even if you find Malabar, it's probably going to be stale. I'd suggest you go to the best hipster coffee roaster/bar in town, taste their best and freshest coffee, and pick what you think might go well in a beer. I personally wouldn't pick the darker espresso roasts, but rather the lighter filter roast."
Thanks for the feedback.
The brewers notes say:
Can be anything you like. Just stay away from earthy and astringent varieties/roasts.
• Peruvian - 50% of total
• Indian - 50% of total
For those that have made a coffee porter/stout, what did you use?
I definitely don't want astringency therefore I will 'dry bean' cold in the keg.
