To be honest, I don't have definite information. Some shows claim to be based on true stories but take creative liberties. Maybe 'La Senora Acero' is one of those cases.
Tequila originated in the area around the city of Tequila in Jalisco, Mexico. It's made from the blue agave plant. The native people in the region had been using the agave for centuries before the Spanish arrived. The Spanish influenced the production methods and later, commercial production began.
There was a story of a group of friends who decided to do a tequila tasting tour in Jalisco. They visited different haciendas and tried various types of tequila. Along the way, they met an old tequila master who told them about the different flavors and how to properly taste tequila. This experience led them to discover new favorites and created memories that they would always cherish.
I'm not sure if the novel you mentioned really exists because I don't have enough context to confirm if it really exists. At the same time, I can't be sure if the name " Tequila " appears in the novel. If you can provide more information, I will try my best to answer your questions.
