Which of the following agave spirits is primarily produced in Oaxaca?

The correct answer is Mezcal, which is primarily produced in Oaxaca, Mexico. While both Mezcal and Tequila are agave spirits, they differ in terms of their production methods and the types of agave used. Mezcal can be made from a variety of agave species, with the most common being Espadín, and it is traditionally produced using artisanal methods, often including the roasting of agave hearts in earthen pits, which gives it a distinct smoky flavor.

Oaxaca is known for its rich mezcal production due to the region's ideal climate and the cultural heritage associated with agave distillation. In contrast, Tequila is a specific type of mezcal that is produced only in designated regions of Mexico and is made primarily from the Blue Weber agave. Rum is a spirit made from sugarcane or its byproducts, and Grappa is an Italian pomace brandy, making them unrelated to agave production. Thus, Mezcal stands out as the spirit closely tied to Oaxacan traditions and influences.
