If you're going to Oaxaca, check on their website to make a reservation as soon as possible! The…read morespots fill up quickly! Jim G. and I were lucky enough to find one pop up on a very convenient day for us, so off we went!
When you find the spot, there's a little buzzer you'll need to press so they buzz you in. Then head on up to the bar for your (mostly) private educational tour through mezcal. We spent a little more than an hour with Bastian, who was great! He asked both Jim G. and me many, many questions about what we do and don't like to drink and why. Doing this allowed him to tailor a tasting for each of us; and, if you read any of my reviews, you know we enjoy our libations, so of course we went with the 5 mezcal tasting (you can do 3, 4, or 5).
As we were tasting and learning, Bastian asked for feedback and even changed what we were going to taste mid-journey. In a couple cases, he gave us some options (not that we knew what they were by name, but things like 'more bold' or 'same plant, different process,' etc).
We learned a lot about mezcal, enjoyed ourselves, and walked out with three bottles--one for the room while we were in Oaxaca, and two to take home. I would go back again if in Oaxaca!
