Viezfest Trier

Trierer Viez is a lightly fermented apple wine, traditionally pressed from Mosel and Eifel apple varieties, unfiltered and with a moderate alcohol content of about 5 to 7 percent. It is traditionally drunk from the Viezporz — a characteristic, broad-bellied stoneware jug. The tradition dates back to the Middle Ages and is now an integral part of Trier's culinary culture. In 2017, Trier's Viez culture was added to the national inventory of intangible UNESCO World Heritage.

The Viezfest takes place every two years and is the central public celebration of this tradition. The organiser is the Trierer Viezbruderschaft, an association of Viez producers, restaurateurs, and enthusiasts. Several producers set up their stalls on the Domfreihof and serve their products — from dry to semi-sweet varieties, as well as Viezbowl and Viezsekt (sparkling Viez). A limited artist mug is designed annually by a Trier artist and sold in a limited edition. For 2026, Roland Dahm has designed a motif of the Porta Nigra.
