Distillerie Berta is based in Mombaruzzo (Monferrato, Piemonte) one of the most respected artisan grappa producers in the region, known for single-varietal (monovitigno) expressions from the pomace of the leading Piemontese wine varieties. Berta sources pomace directly from estate vineyards immediately after pressing, distils in copper alembic stills, and releases each grape variety as a separate expression. Freshness of the pomace is the critical quality variable: fermentation continues after pressing, so immediate distillation is essential for aromatic integrity.

The Berta range at Bouchon is anchored in monovitigno expressions: Nebbiolo pomace (from Barolo and Barbaresco production), Moscato d'Asti pomace, and Chardonnay pomace. Each produces distinctly different spirit character Nebbiolo grappa reads tannin-heavy and earthy, reflecting the variety's deep structure; Moscato grappa is floral and aromatic, carrying the variety's fragrance directly into the spirit. For programmes building an Italian digestif offering or pairing grappa with cheese and dessert courses, Berta's monovitigno range makes variety-specific character accessible and demonstratable at the table.
