Thoughtfully sustainable. Deliciously made.

Since 2001, we have been curating coffee with character – from its origin to your cup.

More than coffee – an attitude

It all starts with a conviction: coffee can be better. Better in taste, better for the people behind it, better for the planet. When Michael and Claudia Gliss opened their Contor in Cologne in 2001, it wasn't a business idea – it was a promise.

Today, GLISS Caffee is one of Germany's most uncompromising coffee brands: owner-managed, organically certified, and driven by genuine passion – cup by cup.
