Fermentation
There are three stages to the tequila fermentation process.
Propagation (Aerobic Stage) - During this stage, the yeast population develops and increases the number of individuals and their adaptation to the acid substrate of the agave juice. This stage lasts between 24 to 48 hours.
Production (Anaerobic Stage) - This stage involves the yeast consuming the sugars contained in the agave juices to transform them into alcohol under an exothermic reactions and the production of CO2. This stage takes around 72 hours on average.
Decrease - Once the yeast consumers all the available sugar, it is dying due to the lack of food until declaring the end of the fermentation stage. This stage lasts around 12 to 24 hours.

Yield during Distillation
The yield, the percentage of alcohol in a solution of alcohol wash, is subjective during the distillation process. For each product, there is a certain profile which is obtained in the distillation process by cutting tails and heads. The average standard yield of a distillation is between 85% and 90%.
