Now, nobody likes a good alcohol-related theme more than I do... well, except perhaps Horace.
Nobody likes a good alcohol-related theme more than Horace or I do. And this one is fun: a circle of different names of alcoholic drinks, shaded in just so you can see that it indeed is a circle. All six exemplars are well chosen. And I like that GIN and STOUT, the two that aren't diagonally displaced, are clued without reference to the drinks.
And yet. And yet. THEROUNDSONME... it almost hits the nail on the head. Only, how does the "on me" fit in? Maybe I'm just being nitpicky. It just bothers me a little.
There is a ton of theme here, and all of those diagonal answers require triple-checked letters, which makes for some challenging fill. Thus, MASTIC. That was my error: I hadn't heard of that before, and I chose an L to start it with, crossing it with 9A: Leaky parts of an old tent, often: SEAlS, right? Well, SEAMS works better, I can see now.
That being said, I like MARIPOSA, HOTMEALS, and JAUNT is very nice also. EAGEREST is fine, although I'd probably say "most eager" in actual conversation.
1A: Common name for a cowboy (DUSTY) is cute, and I'll give it a B. My first answer was 1D: Opposite of births (DEATHS).
Horace and Frances will know that MACHU makes me think of another spirit: Pisco. A pisco sour is a very fine mixed drink.
