My $.02.
Does seem a little smoother and has different, perhaps mellower taste than Black Label.
I mix it with Coke (as in Cola, I can hear you jack*sses now). Pretty much have to, for both JD varieties, although I haven't had the single barrel, Gentlemen Jack, or any other higher end JD. All of them is too sweet for me not to mix. To me, it's not sippin' whiskey. It's drinkin' whiskey.
But yeah. Gimme sixpack of Coke (see above), some ice, a bottle of Green label, and I can catch a decent buzz.
