Domaine Phusis – The Original Expression of Swiss Terroirs

A vineyard-researcher revealing the soul of Alpine landscapes

Based in La Sarraz in the canton of Vaud and driven by the singular vision of Steve Bettschen, Domaine Phusis has emerged as one of the most honest, transparent and luminous voices in contemporary Swiss wine. Part researcher, part craftsman of the living world, Bettschen has spent more than a decade crafting wines of rare aromatic clarity, the result of total commitment to biodynamics, Alpine micro-parcels and deliberately minimalist winemaking.

Phusis is not a conventional estate: it is a geological reading, an intimate exploration of Swiss terroir, a form of craftsmanship in which each wine carries the name of its soil — limestone cliff, gneiss, scree, marl — as a reminder that the earth comes before technique.

A Mosaic of Distinctive Terroirs

The strength of Phusis lies in its ability to unify the geological diversity of French-speaking Switzerland and Valais into a coherent, precise and deeply natural expression. The estate works on a broad palette of soils:

• limestone cliffs: vertical tension, penetrating salinity,
• gneiss & metamorphic rocks: mineral brilliance, Alpine straightness,
• rocky scree: dense grain, vivid energy,
• marl: fine texture, saline length,
• high plateaus: crystalline acidity, vibrant aromatics.

Every cuvée is conceived as a fragment of landscape, a mineral photograph of its place of origin.

Grape Varieties — Alpine Richness and Swiss Heritage

Steve Bettschen cultivates varieties that most faithfully express the character of each terroir:

• Petite Arvine
• Rèze
• Humagne Rouge
• Gamay
• Pinot Noir
• Furmint
• Marsanne
• Riesling
• Altesse

Often rare or confidential grapes, chosen for their ability to translate the soil’s personality and the purity of the Alpine climate without distortion.

Philosophy — Letting Nature Speak

The estate’s approach is among the most rigorous in Switzerland. Phusis expresses better than almost any producer the very concept of living wine:

• strict organic & biodynamic viticulture,
• hand harvesting with severe selection,
• no oenological additives: no enzymes, no cultured yeasts, no corrections,
• spontaneous, sometimes very long fermentations,
• extended ageing in barrels, demi-muids or amphorae,
• minimal sulphur, only when necessary,
• bottling without filtration or with ultra-light filtration,
• constant pursuit of natural balance.

The key word: energy. The wines vibrate, breathe and unfold without artifice, offering a direct reading of their terroirs.

Wine Style — Alpine Tension, Purity and Verticality

Phusis wines stand out with an immediately recognisable personality:

• razor-sharp, thirst-quenching freshness,
• straight, saline, sometimes iodised minerality,
• crystalline aromatics (citrus, Alpine herbs, wet stone, fine flowers),
• precise, elongated structure,
• remarkable digestibility,
• moderate alcohol and natural balance,
• long finishes driven by the energy of the soil.

Whether white, red or skin-contact wines, all share the same ethic: purity, finesse, truth.

Key Cuvées

• Arvine sur Falaise
  Petite Arvine with breathtaking tension, deep salinity and a vertical finish. A benchmark expression of Swiss limestone.
• Arvine Brut Nature
  A natural sparkling wine of great finesse; dry, mineral, incisive.
• Pinot Noir – Clos du Mormont
  High-altitude Vaud Pinot Noir: precise, racy, finely structured. A model of limestone elegance.
• Rèze du Haut Plateau – MetaPhusis
  A rare wine from a nearly vanished variety; Alpine acidity, crystalline profile, unique identity.
• Humagne Rouge / Gamay / Furmint – MetaPhusis
  Biodynamic micro-parcels; vibrant, deep cuvées highly sought after by avant-garde sommeliers.

A Landmark of Swiss Natural Wine

Domaine Phusis stands as one of the purest and most demanding voices of natural wine in French-speaking Switzerland. Produced and released in tiny quantities, its cuvées are now sought after by specialised cellars, Michelin-starred restaurants and lovers of authentic living wines. Phusis embodies the idea that wine is not shaped — it comes into being, filled with energy, minerality and truth. A rare estate, profoundly Swiss, elevating natural wine to the level of geological and emotional expression.
