I'm still on the same Denny train!
I've got it fermenting right now in an IPA, and then I"m going to save it and wash it and use it in my oatmeal stout.
The other yeast I'm quite taken with is Wyeast 1335. It's an English strain, but with a dry and malty taste to it. I ferment it cool, right alongside the other batch with Denny's, and comparing them head-to-head. (I'm doing 10 gallon batches, splitting them into 5 gallon fermenters and using different yeast in each).
My experience with the Denny's strain in the oatmeal stout is a richer mouthfeel than other other strain I've used.
