I went to a bunch of tequila distilleries a couple of weeks ago. Here are some videos of tequila production.
Harvesting an agave plant at Sauza.
Cutting up the agave at the Don Julio distillery to prepare it for baking.
At the Olmeca Altos distillery, crushing the baked agave using the stone tahona.
At the Patron distillery, crushing agave in the rollermill, the more modern way to do this. Both Patron and Olmeca Altos use a blend of tahona and rollermill- crushed agave.
Then the agave ferments,
And is distilled to make tequila.
