I was just playing with this style of recipe. I have never had a commercial Oatmeal Nut Brown that I can remember but it just sounds delicious. I do like my brown ales on the real nutty side.
For the hop schedule, I borrowed it from the Surly Bender recipe from Northern Brewer.
For my next brew day I want to do a brown ale, so it is between this and a Rogue Hazelnut clone I found.
Please let me know what you think.
