Tequila can be made only from blue agave, while mezcal can be made from any type of agave. Mezcal bottles often contain a worm or other foreign object, while tequila bottles do not. What are the other differences, if any?
Sorry I've been MIA for a few days; I am posting this from Boston's South Street bus station, after spending a couple of days with family, celebrating Celeste Bea's graduation from Simmons. A happy day, and congratulations to Celeste, Keith and Vikki. I'll post late tomorrow, with an extended reading list.
