Step 1 : Introduction to the question "Which spirit can replace tequila in cocktails to add a smoky flavor?"
...Tequila is a type of mezcal, but not all mezcals are tequila. To be tequila, the spirit must be made from blue agave and produced in the Mexican state of Jalisco. Mezcal can be made from any of 30 different types of agave and produced anywhere in Mexico. Another difference: Tequila piñas (the heart of the agave plant resembling a pineapple) are cooked in large brick or stainless steel ovens, while mezcal piñas are usually cooked in a pit lined with volcanic rock. This gives mezcal a smoky, earthy quality that ranges from sweet and bright to spicy and savory.
