Norway

Aass in Drammen, brewing since 1834, is Norway’s oldest working brewery, and Ringnes in Oslo its largest. On farms in western Norway brewers kept their own yeasts, called kveik, for generations. The state retailer Vinmonopolet sells all beer over 4.75%, so brewers make weaker versions for supermarkets; the craft brewer Lervig has complained that slow listing there hurts fresh IPA.
