 The earliest documentation of the beer being exported to other regions is from records in the nearby town of Wschowa from 1671 . Rules established by the local <unk> ' guild established that the penalty for charging less than 12 groschen for dying a hat was a barrel of Grodziskie . In 1694 , the nearby city of Poznań listed a bill for expenses that included entries for " Grodzisk beer " at the rate of 15 guilders per barrel that had been purchased as gifts for important people . At that cost , it can be seen that the product was valued as a premium beverage , since local beer produced in Poznań at the time cost only five to six guilders per barrel . Other records from Poznań in 1712 show that the two mayors of the city were receiving Grodziskie beer as a portion of their compensation for their service . By the 18th century , the beverage 's reputation had spread throughout Poland , and it became one of the most expensive beers in the country .
