 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 hatters'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.
