Instead of pasteurization, draft beer is produced under an advanced low-temperature membrane filtration system to maintain a certain biological stability.
Through a pore size of only 0.45 microns, the filtration system keeps out most of the bacteria while preserving the healthy active enzymes and other nutrients intact, providing a nutrient-rich product that is fresh, dynamic, crisp, and cool.
