I'm a recent member, but I've already bought probably a dozen bottles of Scotch and Mezcal from Flaviar that I just couldn't get locally (even at our really big, really well-stocked liquor store, T.W.).
Easy examples are a nice Johnnie Walker Blue Ghost and Rare, and Highland Park Dark 17-year-old. These were really cool finds that I just couldn't get elsewhere. I got an Inchmurrin 18-year-old that also was a pretty interesting find.
Then within Mezcals what I loved was the variety that I could get. Just a few clicks and I had a Tobala, a Tepeztate, and an Arroqueno mezcal on the way to my house. Espadin is all over the place, of course, but getting different agaves can be challenging, and the selection I found at Flaviar was fantastic.
Looking forward to continuing to expand my bar with you!
Bottom Line: Yes, I would recommend this to a friend
