 Budweiser Budvar beer is produced only in the brewery headquarters at České Budějovice according to the Bavarian "Reinheitsgebot" beer purity law from 1516, drawing artesian water from wells beneath it and brewed with Moravian barley and Saaz hops, known as a noble hop variety, from the Žatec region.The lagers are matured for a minimum of 90 days.Nick Redmayne of "The Independent" newspaper contrasted this with 72 hours of lagering (maturation), after which mass-market beers are sold.
