Thanks for suggesting the topic. I was interested in these numbers from more reliable sources. Apparently, a very detailed statistics is available in the BarthHaas Report (https://www.barthhaas.com/downloads/berichte-broschueren)

Here is a approximate bier production per year for comparison:

World's total: 200.000.000.000 liter = 200 Gl

Germany: 9.000.000.000 liter = 9 Gl (5th place; try to guess the leaders. We are talking about quantity, not quality)

Radeberger Group: 1.000.000.000 liter = 1 Gl

Bavaria: 2.300.000.000 ~ 2 Gl (terribly sorry, I didn't find Frankonia separately :) But for the region's defense I should say that excellent report comes from Nürnberg.

Data for years 2019-2020. There is even Top 40 breweries in the world in there.
