My head's still buzzin' after the three and a half hour master seminar/tasting with the legendary David Suro-Pinero the other day. It was a small knowledgeable group and David was able to use his Tequila 101 slides but go way beyond the basics. Way beyond. Rather than me summarize, I found this recording of a training class he did a year or so ago. Take the time, if possible have a spot of Tequila and enjoy! https://www.youtube.com/watch?v=6LG1MISYiiI
