Dinner at the Kümins
Tradition, wine & indulgence in the wine cellar at Freienbach on Lake Zurich
The Treberwurst is a truly unique Swiss sausage specialty with roots in the Lake Biel region (Canton of Bern). Its name comes from Treber (also called Trester) — the leftover pulp from pressed wine grapes. Yes, it's a sausage steamed over boozy grape waste. Only in Switzerland.
Back in the 1950s, winemakers around Lake Biel started cooking their pork sausages in the rising alcohol vapors produced while distilling Marc (grape pomace brandy). What began as a simple winemaker's lunch turned into a beloved tradition for visitors in the early 1980s — and has been drawing crowds from all over Switzerland every winter since.
Treberwurst is essentially a raw Saucisson-style sausage (similar to Vaudois Saucisson, but finer and leaner) that gets cooked in the steam of fermenting grape remnants. The sausage itself contains no alcohol — it just picks up its distinctive aroma from the vapors. Think of it as a booze sauna for sausages.
In autumn, the grapes are pressed. The pomace (skins, seeds, stems) ferments for about 3 months.
The fermented pomace is distilled in a copper still — producing Marc, a clear grape pomace brandy at ~40% ABV.
The raw sausages are placed over the steaming hot pomace in the still and gently cooked for about 50–60 minutes at ~78°C.
The finished sausage is sliced thick, doused with hot Marc, and flambéed at the table — intensifying the spicy, smoky wine aroma. Because why not set your food on fire?
Although Treberwurst originally hails from Lake Biel, the Kümin Brothers Winery in Freienbach on Lake Zurich has adopted this tradition with spectacular success. Every year in January, the Kümin wine cellar transforms into a cozy, rustic feast hall.
Long wooden tables and benches fill the production rooms. The atmosphere is cheerfully rustic — think Swiss wine cellar meets village feast. On the menu: Treberwürste straight from the still, accompanied by Papet vaudois (a hearty potato-leek gratin from the Vaud tradition) and plenty of house wine.
If you're not a fan of boozy flavors, you might want to stick to the sides — the Treberwurst smells and tastes distinctly of brandy steam! You've been warned.
Marc (also known as Tresterbrand in German) is a brandy distilled from fermented grape pomace — similar to Italian grappa. After pressing the grapes, the solid residue (skins, seeds, pulp) is left behind. This gets fermented and then distilled.
The result is a clear spirit at about ~40% ABV, with a fruity aroma of grapes and yeast. In Swiss German dialect, it's also called «Träsch» or «Drusen». For example: the Leutschner Marc by the Kümin Brothers — carefully distilled, aged in oak barrels, 42% ABV, about CHF 41 for 75cl.
