There are around 1,300 breweries in Germany. They exist in every region. Lot of them are private, long lasting and with a family traditions. Krombacher was ranged as a most popular beer in Germany the last year and after comes Bitburger, Warsteiner and Becks -the most exported German beer.
Berliner Kindel is one very popular beer in Berlin. You can find them in some other countries, but in Berlin, Kindel Weisse Red or Green (Rot oder Grun) you can find just in Berlin. In bottles you can buy them in supermarket and in bars it’s typically served in a bowl-shaped glass with flavored syrups, such as raspberry (Himbeersirup), or artificial woodruff flavoring (Waldmeistersirup). One story says that long time ago when French people came in Berlin, they could not drink an ordinary beer and that they had put some syrup in.
Bavaria, par example is the part of Germany where is located about 560 of breweries. This region is place where is organized every year in the end of September and beginning of October the Oktoberfest, the most famous beer event, where the last year par example 7.5l were sold, (that was about 70.125.000e) they are selling there just beer from Bavaria, in so called Mass- 1l pot, and the price is between 9 and 10e.
I hope that you also remarked that in Berlin, its allowed to drink it in U-bahn and S-bahn, and it is not permit in some others cities in Germany, and in some parts of America this is a crime and police can take you into the prison.
