And I was wondering if you split the coffee beans could you make an extract much in the same way you would with vanilla?
I just sampled my first oatmeal stout. I added about 12 ounces of coffee at bottling. After three weeks there is a pronounced coffee taste (not unpleasant). But I am hoping it will smooth out in a couple of weeks. It really depends on how much coffee taste you want.
I cold-brewed: I coarsely crushed the beans in a grinder and put them in a muslin bag. I placed that in a sanitized jar, added cold bottled water and left it on the counter for 24 hours. Every so often I would shake it. At bottling I removed the bag of beans and dispensed the coffee right into the bottling bucket.
Hope this helps a bit. Good luck!
