Tequila is made from agaves.

The tequila agaves are grown on plantations. They are large plants. The major plant is Agave tequiliana, a light blue plant. Much effort is required to harvest the plant. The leaves are cut off (dangerous) and eventually the crown is exposed, which goes on to fermentation.
