Kölln Kernige Haferflocken

Köllnflocken is an iconic German brand of oat flakes, specifically the 'Kernige' (large/textured) variety. The brand dates back to 1820 when Peter Kölln founded a horse-powered mill in Elmshorn, Germany. Over two centuries, it has grown into Germany's most recognized oat brand, maintaining its headquarters and primary production facilities in the same town.

The product is produced using 100% whole grain oats, often sourced from domestic and Nordic farmers. As of 2026, the brand remains under the ultimate ownership of Peter Kölln GmbH & Co. KGaA, which continues to be a family-led enterprise. The company has expanded its portfolio beyond simple flakes to include mueslis and oat drinks, while keeping its core manufacturing deeply rooted in Northern Germany.
