The concept that has been developed through this semester gives brewer guilds and private hand brewers the opportunity to become co-brewer/prosumer in producing their own promising recipe in larger scale and sell the beer produced with Viborg Bryghus as broker. The prosumer beer will be stored in a beer bank and on the webpage of Viborg Bryghus the prosumer can check the balance of the account, how the sale is going and his own consumption. The prosumer can withdraw his beer in Café Munken and it is also in the café that other customers can buy the prosumer beer.
