The burčák season in the Czech Republic begins in early August, marked by the sale of the partially fermented grape juice and various regional festivals. In South Moravia, Chateau Valtice reported strong early sales despite a prolonged drought that reduced grape size and potentially lowered juice yields by 20–40 percent. 

Regional celebrations, including parades and tastings, extend from early September into mid-October across towns such as Mutěnice and Hodonín. The beverage, which typically contains 1% to 7% alcohol, is legally required to be produced from grapes harvested and processed within the country. While traditional views suggest health benefits, medical experts note that the drink's high sugar and yeast content can cause digestive issues. The season generally continues through November, eventually transitioning into the tradition of Saint Martin's wine.
