About

Delftse Donderslag is a lager-style bock from Delftse Stadsbrouwerij De Koperen Kat, the craft brewery established in Delft in 2011. At 7% ABV, this beer delivers a flavour impact worthy of its name—a thunderbolt in Dutch. Built on caramel malts, the beer develops a gently sweet, full-bodied character with caramel notes and subtle fruity esters. The colour ranges between gold and amber, while the nose offers grainy notes with hints of rum sweetness and fruit. An approachable bock that balances accessibility with genuine flavour intensity, matching the dramatic promise of its name.
