About four years ago, Jameson finished its Irish whiskey in barrels that once held a roasty, toasty stout and released “Caskmates” onto the world. The result was a bottle of hooch with coffee and chocolate notes faint enough to work instead of distract. Now Jameson is playing mad scientist again. Jameson Caskmates IPA Edition is an Irish whiskey finished in Irish Pale Ale-seasoned barrels. Couple things to unpack here. First, we’re not sure how an Irish Pale Ale differs from the IPA you’re used to, though we’d guess it’s a little more malt driven with a more pronounced bitterness. Second, we’re not sure how much of the flavor would appear in the whiskey, as those notes aren’t as aggressive as some roasted malts. According to Jameson, the whiskey packs floral notes with some grapefruit, and a citrus component comes through with every sip. Our best advice is to try it for yourself to find out, which is exactly what we plan on doing.
