Most Satisfying Vertical Tasting?

I have yes. We did a Black Tuesday vertical that way and an Abyss vertical. Blind tastings, in general are great imo. Sometimes when a hyped beer is brown bagged is fun, as it takes out any bias or pre-conceived notions. Some have such great palates, and know certain beers so well, they can even guess them correctly blind. I'm not one of them, but know a few that can.
