I went to Ireland last year for a project and stopped at Teeling and Jameson in Dublin and took the tours, then I went to Midleton where most of the actual product for Jameson is made. I got to say, it was worth it. My only regret was driving past Tullamore and not stopping in.
Favorite of all time:
Midleton Very Rare 2005. Hit me with a BLAST of butterscotch on the first sip. The other years are "great" but 2005 was epic.
Go to: Standard Jameson. It's flexible enough to be served on it's own or mixed with something if someone doesn't like it straight. The 12 year old is very nice as well.
Favorite in the summertime: Green Spot. I think they age it in old sherry casks and it picks up a lot of fruit and citrus notes from that. A hot, humid day brings out those notes. Goes great with slow smoked ribs and/or brisket.
Favorite in the wintertime: Redbreast 12. Nothing is better than watching a blizzard through your window while sipping on the deep notes of Redbreast.
Recent find: Paddy. It's a blend (which some people look down on) that seems like a good all-rounder. Might be my go-to if I can find it around.
Surprise find: Teeling single grain. Made from corn if I remember right. Normally I get a hit of corn on the finish, which I don't like in a whiskey but not with this one. It's also a good summer choice.
Note: I REALLY like Irish Whiskey.
