Since the concept of craft beer was initiated by Americans, we quote the requirements of BA, the American Brewers Association, for craft beer merchants:
1, small
The annual output is less than 6 million barrels (953,880 tons), and the beer produced is used for commercial transactions.
2. Autonomy
Non-handmade brewers or companies, whose shares cannot exceed 25%.
3. Tradition
Most of the flavor of beer brewed by brewers should be obtained from traditional raw materials and fermentation technology.
