The fermentation process takes approximately 54 – 58 hours. At the end of the fermentation process, the product is now called “beer” and contains 12 – 18% ethanol, and it is pumped into the beer well.

There are two types of fermentation processes called continuous or batch. In a Continuous fermentation process, the “mash” flows through several fermenters until fully fermented. In a batch fermentation process, the mash stays in one fermenter before it is transferred into the beer well before it goes through the distillation process.
