(Cherry Chocolate) Oatmeal Robust Porter

I recieved a PM requesting the recipe, and since there was a delay in getting this brewed, I thought I would solicit for comments on it, that I had posted I was going to brew I think last weekend.  What do you think?

Recipe should use EKG rather than US Goldings, but I'm subbing with hops I have onhand.

With a nod to Jamil's Black Widow Porter, which is what I based a lot of this recipe on.

I like the creamy head of an oatmeal stout and have a bunch of flaked oats on hand so incorporated them into the recipe.  I will be toasting them at 300F in a pan in the oven with occasional stirring until lightly browned and nutty smelling.

5 gal =  straight recipe

5 gal = will get chocolate and cherries in secondary, after at least two weeks in primary ramped up to steady 65-66F. 
For 5 gal beer, use 1/2 lb low fat, unsweetened chocolate powder that is stirred in with cherries
when pasteurizing them for 20 min at 160F.  Leave on cherries/cocoa for 10 days. 
Use minimum of 2 lbs cherries per gallon of beer, and I will also be adding ~10 oz. "Tart is Smart"
natural tart cherry juice concentrate since I have it onhand.  I haven't decided if I will bother
pitting the cherries - probably not.  I will use frozen Bing cherries I picked and froze last summer.

Two to three weeks maturing in the keg in the 35F kegerator should serve as a diacetyl rest.

Thanks for posting this.  I'm anxious to try it.


I formulated based on what I have on hand.  It wouldn't need the wheat malt, but I added it because I have tons, and it is foam positive for the head.  No real need for two types of base malt but I think it will work well.  And you could use 2 lbs of caramel 40 rather than 1 lb each of 60 and 20, etc.  Of course you know that the ingredient amounts will vary depending on your brewhouse efficiency.  I improved my efficiency considerably once Martin's newer versions of Bru'n Water came out.  And, I am mashing a bit warm because I want some body.  I'll be coming close to his Black Malty water profile.

I edited my recipe above to follow Jamil's Black Widow Porter hopping schedule, which I trust more than what I had previously using cascade for aroma and no fuggles.  It's just safer.  I had originally thought it would be interesting to try something other than fuggles, since I have read some posts of people who detest that hop in porters.  Still, I don't think it's a hop that offends my tastebuds.

Just on first glance there a lot of different thing going on in the grain bill. Not necessarily a bad thing, but I wonder how much you need the wheat and aromatic with the other flavors going on.  Also, why are you bittering with a lower alpha Golding hop? Do you have something higher in alpha to bitter with? Finally I like the flavor/aroma hops, but not for the chocolate/fruity half of the beer. I am not a big fan of fruit beer with a strong hop flavor. Not sure how you can remedy this since if you take the hops out, the non-fruit beer will suffer.
