Good question, but worse answer. For example, Plzeňské has a world reputation, but I don't think it's a **** that was brewed before the year 89. At that time it matured for a few weeks, but today, a few days. Here, quantity prevails over quality. For small breweries, so that they do not disappear, they brew **** from the same raw materials, but they are slightly above the cost of production. In the case of well-known breweries, it is primarily a matter of profit, and in the case of others, the consumer enjoys (disgusting word)! And I, personally, drink **** from a brewery that is a national company and the taste is excellent and cheaper than Prazdroj!
