TEQUILIA
Tequila is made from distilled sap from hearts [piñas] of the blue agave or maguey [mah-gay] plant.
The blue agaves are still planted and harvested by hand. Its blue-gray sword-like leaves give the plant the appearance of a cactus however the plant is related to the lily and amaryllis. Although it shares a common habitat with many cacti, it is not one itself and has a different life cycle. It typically takes the plant 8-12 years after planting before it is ready for harvesting.
The name agave comes from the Greek word for noble and there are 136 species of agave in Mexico. Of these the blue agave - agave tequilana weber azul - is the only one allowed for use in tequila production.
The harvested agave heart is chopped to bits, fed into ovens and cooked for up to three days. After it is cooked the softened plants are shredded and juiced. This juice, called aguamiel [for its golden syrupy appearance] is then pumped into vats where it typically is mixed with sugarcane and yeast before fermenting. By law, the mixture MUST contain no less than 51% agave.
There are four varieties of tequila:
White or silver tequila is not aged and no colours or flavors are added.
The gold variety is un-aged but colour and flavor, usually caramel is added.
Tequila reposado (rested) has been aged at least two months in oak barrels and colouring and flavoring agents usually have been added.
Anejo (aged) tequila has spent at least one year in oak barrels, also with added colouring and flavoring
THE WORM [GUSANO]
There is no worm in Mexican-bottled tequila.
There is however a worm in American-bottled tequila.
We have encountered two explanations for the worm:
It is only a marketing ploy and not a Mexican tradition.
It is a test to ensure the ratio of alcohol is sufficient. If there is enough alcohol in the bottle the worm is supposed to die.
Apparently the worm gimmick was initiated in the 40's to booster Mezcal sales. The myth that came to be synonymous with the worm is that you get a psychedelic high after ingesting the dead worm. I have even spoken to individuals who swear they got high from the worm however I simply have to question their judgment since they drank the tequila to get to the worm so their experience is somewhat skewed.
There are two types of gusano in mezcal:
The larvae from both types of gusano are commonly eaten as food.
