I think the differences between the two are as follows:

1. Raw materials: In addition to using malt, industrial beer also contains other raw materials, while craft beer does not.

2. Brewing process: Industrial beer uses lager technology, and craft beer uses ale technology.

3. Taste: The taste of industrial beer is lighter, while the taste of craft beer is more mellow.

4. Fermentation time: The fermentation time of industrial beer is generally about 7 days, and the fermentation time of craft beer is as long as 2 months.
