That Mizunara and the DB Generational that were onsite at the cellar only are some of the best stouts they've ever done.
That original Double Bourbon Barrel Generational that was on site only (that I was lucky enough to be in St. Louis for) is my favorite beer they've produced. And you're right - the green wax Mizunara wasn't far behind.
Got to visit the cellar over the weekend and had draft pours of D16, Phase Rule, and Persona "Grand Crew". That Persona blend was awesome and made my night. Unfortunately only have CK to bring home.
Definitely feel like if For LC wasn’t put in the book this year would have ended and it would be renewal time.
Going off memory (which is poor-ish)the other “optional” bottles were D12; DBD Stagg Jr; Continuance 2; Symmetry; Cellar 10th Anniversary BW
