Oatmeal-Milk Stout With Espresso Recipe Input

thelorax121 · 11-03-2009, 03:09 PM

Inspired by the Terrapin/Left Hand Collaboration Depth Charge, I am planning an oatmeal milk stout with some espresso added to the keg. The recipe below is supposed to be a combination of an oatmeal and milk stout, the latter of which I have never brewed, so any input is welcome. I don't know whether to use a british or american yeast, for those of you who have brewed milk stouts before, does the lactose leave enough residual sweetness with a higher attenuating yeast? My end goal is something with a creamy mouthfeel, slight sweetness to balance the bitterness of the espresso and roasted malts. Please let the critiques flow!

I am doing something similar, a chocolate milk stout, but I am using Fuggles and Willamette. I am going with Irish Ale yeast (Wyeast 1084)

I would use very little lactose, as in less than .5 lbs. Honestly when I used it , I didnt care for it.

If you want the flavor of the espresso without the bitterness or astringency, rack on top of whole espresso beans. Trust me here, the best coffee beers I've had have been brewed this way, and the brewer who taught me this trick took a silver in the coffee beer category at this year's GABF so that should speak for itself.

I was going to do a cold extraction with the espresso (since I live in Athens, I can actually buy the same beans that they used), then add it when I keg, so that I could get the exact amount of coffee flavor that I was looking for, why would racking it on whole beans be better?

I'm no coffee expert, but my guess is that doing a cold-press extraction would yield similar (if not identical) results; I think the important thing is to not actually brew the coffee. It's possible that the presence of alcohol somehow impacts extraction, but otherwise I view aging with beans in the keg to be pretty much the same process as cold pressing. And I would definitely agree that you have less control over the strength of the coffee flavor when you just age on the beans (though for me that's part of the fun!).

Cold extraction works great. I use it for my Chocolate Coffee Stout. I think you are on the right track with your receipe. Here is mine - it has been very well recieved:

Boiling away right now. Turned out to be a really nice brew night. Cold out, but nice with the heat of the kettle. Everything went as posted above except I subbed the chocolate malt for chocolate rye. Thought it might be an interesting addition to the beer, and the brewer from our local brewpub uses it in a lot of his stouts, anyone have any experience with it?

BillyBeer · 11-05-2009, 09:31 PM

I use 3 lb of Chocolate Malt in my stout and I love it. Enjoy the brew!

thelorax121 · 11-06-2009, 05:30 PM

Whoops, i got that reversed. I used chocolate rye instead of the standard chocolate, so I am curious to see what, if any ryesque flavors it will impart.
