Kernel is an awesome brewery and I appreciate that they still bottle as opposed to can. I've hijacked their Pale Ale yeast to make a beer before by using the residue at the bottom of three bottles and making a starter. If I tried cloning one of their beers, I'd probably do something similar, but understandable if you don't try that with bottles of their stronger ones. Almost like a big homebrewer and they do things right.
I'm pretty sure they (at least used to) use US-05 in most of their beers.
