Thanks meck - Hope you enjoy that original SS Oatmeal Stout - its incredibly smooth and silky. If someone goes into that one expecting a harsher, acidic, roasted coffee kick in the teeth, well that's not the stout for that.
I've done a lot of reading about secondaries and will probably forego it with this lower abv beer. Used irish moss last 10 min of boil, fwiw. Congrats on the keg setup, that's ideal. I may split the priming, 2.5 gal DME and 2.5 gal corn sugar, just to experiment. I have a Mr Beer fermenter that could sub nicely as a small batch bottling bucket. Brew on!
*Edit - Oh, and congrats also on going all-grain!
