Tequila 100% Agave:
At times (but not always) you may see ‘Tequila 100% agave’ written on certain Tequila bottles/labels. This basically means that all the fermented sugars come from blue agave, & can’t come from any other source. Generally, these tequilas are more expensive than others.
Whereas if only ‘tequila’ is mentioned on the label, a minimum of 51% of fermentable sugars must come from blue agave, rest can come from a non agave source.
