What makes a whiskey and a whisky different (apart from the obvious missing vowel, wise guys, haha) is that "whisky" comes from Scotland, and is also known as a Scotch. What makes a Scotch a Scotch is, among other things, that the whisky needs to be aged in Scotland, aged for at least 3 years and bottled at no less than 40% ABV.
Jameson's very proudly, made in Ireland. So it's not a Scotch, neither it is a whisky. It's a whisKEY.
Doesn't make it worse or better. It only makes it different from a Scotch.
It is tripled distilled, which is probably why the aroma isn't as strong as say, a single malt whisky (SMW) which is distilled only twice. But it is also the reason why it goes down so smooth, it claims. Though it IS smooth.
Oh and it is sweet. You can smell the sweetness (which is unlike the strong vanilla sweetness from SMWs) and taste it too, even on the rocks. Has that slightly smoky aftertaste which is not distracting.
I like it.
Man, I need to take better pictures of the stuff I drink or throw away that BB for a better phone. :/
