I didn't go, so I don't know, but my dad went to the one on the Wonder recently. He signed up on day 1 but was prepared to cancel if he found out the beers weren't that exciting. He went to Crown and Fin to find out at some point the next day, and the bar manager there (whose name escapes me) said he didn't know the line-up yet, he just decides it more last-minute. So at least on the Wonder, there is no set beer tasting menu that remains constant. He liked the manager a lot at that point and decided to go.
FWIW, even though he'd already had most of the beers on the tasting, it was my dad's favorite ship experience. He loved hanging out, talking beer with other connoisseurs and the manager in charge, and whatever they had (and the amounts) made it a good value.
Editing to add that while I do not know the particular beers, I do know that they were all from the "beer enthusiast" section of the menu, and that is always the case on the Wonder.
