Family Offices & Private Estates
A principal with a villa in Cap Ferrat, a chalet in Courchevel, an apartment in Monaco and a yacht in Port Vauban does not want four wine suppliers. Nor does the estate manager reconciling four sets of invoices. We supply households — one relationship, one standard, every property.
Onshore Cellars was founded by a Chief Stewardess and a Second Officer — the people who ordered wine for principals, chased late deliveries at 7pm, and carried the blame when a supplier substituted the wrong Champagne. That is why household staff find us easy: we answer on WhatsApp fast, confirm exact bottles in writing, flag problems before they become surprises, and never leave a PA or butler exposed in front of the principal.
Family office accounts run as one relationship with per-property delivery and invoicing: the villa on the Côte d'Azur, the chalet in the Alps, the town apartment, and the yacht — same list, same pricing, same contact. Same-day delivery on the Riviera, next-day across France, EU-wide beyond, and yacht provisioning worldwide through the service that built our name.
We plan and stock estate cellars, keep the records, track drinking windows and replenish around the entertaining calendar — Easter in the Alps, August on the coast, the December house party. Where a property lacks cellar conditions, our climate-controlled storage holds the collection at €24 per case per year, insured up to €100,000, and feeds each house as needed.
Birth-year vintages for milestone birthdays, the missing verticals, the allocation wines — Pétrus, Domaine de la Romanée-Conti, Krug Clos d'Ambonnay — our sourcing service finds them and verifies condition before they are offered. First answer within one working day, no search fee.
We run accredited WSET courses (Levels 1–3) for household teams at your property or our Antibes premises, plus practical coaching on decanting, glassware and cellar handling. The same programme trains the interior crews of 40–110m yachts; a household team that has done it serves — and buys — noticeably better.
Ten years supplying the world's finest yachts has taught us how private households work. We do not name clients, we do not gossip, and our invoicing says exactly what the family office needs it to say — no more, no less.
Yes — that is the normal shape of a family office account. One relationship, one price list, separate delivery and invoicing per property, villa, chalet or yacht. The estate manager sees everything; each house simply receives what it needs.
Perfectly happily: household staff are our home crowd. Our founders were superyacht crew — the people who order wine for principals — so we answer fast on WhatsApp and email, confirm exact bottles in writing, and never leave staff exposed by a substitution or a late delivery.
Yes. We plan and stock cellars, keep the records, flag drinking windows, and replenish automatically around your entertaining calendar. Where a property lacks proper cellar conditions, our climate-controlled storage near Antibes holds the collection at €24 per case per year, insured up to €100,000, and delivers to the house as needed.
Often we already know it — many of our family office relationships began on a yacht we supply. One list, one standard, the same bottles ashore and afloat. If we don't supply the yacht yet, send us the list and we'll mirror it.
Yes — accredited WSET courses (Levels 1–3) delivered at your property or our Antibes premises, plus practical service coaching: decanting, glassware, cellar handling. We train superyacht interior teams to the same standard.
