White Hag's Beann Gulban would be a shout, since it's fairly unique to Ireland.
Another unique one would be Kinnegar's new Olan's Tart, not that I've tried it yet (Chill are getting it in on Wednesday).
It wouldn't be fresh (unless it's still currently being made?), but Carlow's Hop Series Sorachi Ace could have been interesting to them, even for the novelty value.
Wouldn't bother with IPAs, reds and stouts would be grand.
What about bringing over a few ciders too?
