I had a few copitas of Fortaleza/Los Abuelos tequila with Guillermo Sauza during his last trip to PHX. Lots of farmer love goes into his product.
When you look at 8-15 years growing time, varietal differences of espadin, tobala, tepeztate, arroqueño, or one of the other 40+ plants used to make mezcal, variations in water source, distillation methods, different woods to roast the piñas, etc then agave-based spirits become quite fascinating. Then there is pechuga mezcal (distilled along with a chicken breast)....
