They limit you to five tastings (although they aren't heavy on that) and they are ALWAYS busy - they open at 10, seems like the best time to get there is not long after they open on a week day if you have that ability. Grab a number on the right when you go in - LOL! I've been there a few times and always gotten someone friendly and willing to answer my un-ending questions
Definitely gotta go by if they let you taste liquids. I've found several I like but not enough to keep from getting bored with them. Need more variety. It keeps me away from those other nasty things.
