Belgian Yeti was always my favorite one. River North Avarice and Shadow Master from Mountain Sun are pretty similar, luckily. For that matter, Black Albert isn't too tough to get and it's the granddaddy of that type of stout. Chocolate Yeti is one of those that has changed a little here and there. It has cayenne each year, but the heat level varies. The years where it has some additional kick have been my favorite years. Did they have an anniversary part last year? That's usually a go-to for me, but I don't recall hearing anything about one last summer.
