The owner gives you 40,000 euros, a six-week Med itinerary, a guest list that includes two serious collectors and a teetotal charterer, and one instruction: "Do not embarrass me." That is a brief, not a shopping list. Structured thinking is what turns it into a cellar.
Reading the brief before you spend
Write down, in this order: how many guest days, what the chef is cooking, who is drinking and what they already like, what will be poured at volume, and what must be there for the one big night. Then build in tiers.
| Tier | Share of budget | Purpose |
|---|---|---|
| House pouring | Largest volume, modest unit price | Deck, lunch, crew-facing standards; rosé, Sauvignon, Prosecco |
| Dinner wines | The working middle | Regional, food-driven, interesting: Douro, Chianti Classico, Chablis, Rioja Reserva |
| Trophy bottles | Small volume, large spend | Two or three names the collector will recognise |
| Contingency | Never zero | Replacements, breakages, the request you did not foresee |
Buy depth, not breadth: six bottles of a wine you can pour confidently beat one bottle each of six you cannot.
Provenance, and why it is the whole game at the top
Above a few hundred euros a bottle, you are no longer only buying wine, you are buying its history. Two identical labels can be worth wildly different amounts because of provenance: where the bottle has been, and how warm it got.
- Buy from the producer, a négociant, a reputable merchant, or an auction house that documents the chain of custody.
- Ask for storage history, and look at the bottle: fill level (ullage), capsule condition, staining, label wear, sediment that has been shaken up.
- Be sceptical of a bargain on a famous name. Counterfeiting is concentrated exactly where the prices are highest: DRC, Pétrus, Lafite, old Bordeaux and Burgundy. Rare old bottles with suspiciously perfect labels are a warning, not a bonus.
- Keep the paperwork. If the bottle is ever resold or claimed on insurance, the invoice and the storage record are the asset.
Storage on a moving vessel
The enemies are heat, temperature swing, light, vibration and dryness.
- 10 to 15 degrees C, stable, is the target. A steady 18 is better than a 12 that becomes 24 in port.
- Humidity around 70%, so natural corks do not dry and shrink.
- Dark, and away from engine-room heat and vibration.
- Bottles under cork stored on their side; screwcap and most fortified wines can stand upright.
- Log everything: bottle, vintage, purchase date, source, price, location on board. An unlogged cellar is an unmanaged asset.
Onboard Notes
Heat damage is the commonest fault in a yacht cellar and it is invisible until you pour. A pushed-up cork, sticky seepage under the capsule, or a wine that tastes cooked and flat when it should be fresh is almost always a storage failure, not a bad bottle. That is the cellar log defending you, so keep it.
