I was trying to find a coffee that would go well with stout, but wasn't sure what to get since I'm not a coffee drinker (yet I love coffee stouts for some reason). I remembered that Modern Times sells coffee and makes a coffee stout so I emailed them for their suggestion. Here's the the response I got:
'We definitely recommend using Black House blend for you coffee/beer needs; it's mellow, chocolatey, and not too acidic.
Add the coffee post fermentation at rates of 3.84oz/gal
Whole Bean, 24 hours. '
I haven't made it yet, but plan on it soon--unless it gets warm too quickly in which case I'll wait till the Fall.
