MAISON RARE WINES 

RARITY IS OUR STANDARD

Fine Wine Brokerage & Portfolio Mandates 

The Strategic Bridge 

Maison Rare Wines is the specialized fine wine and rare spirits pillar of Opulentia Suisse, based in Switzerland. 

We do not operate as a traditional merchant or stockist; we act as strategic intermediaries for high-value liquid assets that reside exclusively outside the public domain.

Our model is built on absolute discretion, provenance integrity, and global access. 

We connect private capital, family offices, and discerning collectors with rare oenological legacies—ranging from Premier Cru Classé vineyards to centennial spirits—operating under a professional Success-Based Fee structure that aligns our interests strictly with the successful execution of your mandate.

Our Core Brokerage Services 

1. Acquisition Mandates (Buy-Side)

For collectors, investors, and family offices seeking off-market fine wines and historic spirits. We leverage our global network of verified cellars and private producers to identify rare allocations and matured vintages before they reach public channels.

• Targeted Sourcing: Bespoke search for investment-grade Bordeaux, Burgundy, Prestige Champagnes, and cult labels.

• Provenance Verification: Rigorous vetting of storage history, temperature logs, authenticity certificates, and ex-château lineage.

• Negotiation Management: Acting as your discreet proxy to secure optimal terms directly from primary sources or private holdings.

2. Divestment Mandates (Sell-Side)

For private owners, estates, and legal representatives looking to liquidate prestige cellars without public exposure. We protect asset value by preventing market fatigue caused by public listing overhangs and auction friction.

• Silent Placement: Direct introduction to pre-qualified High-Net-Worth Individuals (HNWI) and global private buyers.

• Zero Digital Footprint: No public web shops, no social media marketplace listings, no public price exposure.

• NDA & KYC Protected: Detailed portfolio documentation is shared exclusively with verified principals under strict Non-Disclosure Agreements.
