 A legend associated with the history of this beer relates to the Benedictine monk named Bernard of <unk> . Around 1603 , he arrived from the Benedictine monastery in <unk> to find the residents starving and the town 's wells depleted . The brewery was the primary source of income for the city and the hospital . Bernard prayed for the wells and a new source of water suddenly filled the Old Market well . Legends claimed that the newly refilled well had the ability to make whoever drank from it healthy again , and the beer that was produced from the water was far superior to any of the beer the brewers had been able to produce before . The well became a municipal treasure and was given credit for the commercial success of the breweries over the centuries to follow . For over 200 years after the event , the residents of Grodzisk would make an annual procession to Bernard 's monastery to bring a keg of the beer that they made from the well as a show of gratitude .
