I’ve sold a lot of yachts over the years, and many of my clients are serious wine collectors with cellars they’ve spent decades building. The truth is, closing day is the easy part. The relationships are what take real work, and they’re what I care about most. Some of my favorite memories in this business have come well after the close conversations on board over a glass of wine or a cocktail, months and years into a relationship, when a client has become a friend. Showing up after the deal is done, with the same attention I brought to the search, is the standard I hold myself to. It’s the only way I know how to do this job.

My own education in wine came through one of those friendships. Adam, a serious collector who first pulled me into the Napa world, walked me through what made certain bottles matter, and introduced me to the people behind the labels. Everything I know traces back, in one way or another, to him. Through Adam, I came to count two producers as dear friends, John Caldwell of Caldwell Vineyard in Coombsville and Stan Boyd of Boyd Family Vineyards in Oak Knoll. Some of my favorite days have been with Adam and John aboard Adam’s Viking in Costa Rica, chasing fish offshore, then opening something extraordinary at the end of the day. Those trips reshaped how I think about what a serious bottle deserves.

Which brings me to the point of this post. A bottle that took a winemaker years to get right can be undone by four months on a poorly stored boat. For clients who take wine seriously, that’s a loss worth preventing. Here’s what I’ve picked up.

The basics

I’m no engineer for the technical setup, your captain or refit yard is the right call. But here’s the gist, from years of asking people who know.

Heat is the enemy. Wine starts to suffer above 70°F, and what matters isn’t the average, it’s the peaks. A lazarette that hits 95°F while you’re ashore is doing damage fast. Steady warmth is kinder than wild swings. Vibration is the slow killer, so keep wine well clear of the engine room. And direct sunlight through a saloon window will cook a bottle faster than you’d think.

Dennis Groth, who founded Groth Vineyards in Oakville in 1981, has put his philosophy this way: ”Our mission statement is to make the best wine we can every vintage, and if we do that, the rest will take care of itself.” That’s what good storage protects the work the winemaker put in vintage after vintage, so what’s in your glass is what they intended.

Where it goes matters more than what it costs

Location beats equipment, every time. A modest fridge in the right place, interior, lower deck, away from the engine room and exterior bulkheads, will outperform a premium one tucked into a sun-baked saloon cabinet. On larger boats, a proper wine room with dedicated cooling is the gold standard. Your captain or refit yard will know the right specialists to bring in.

What to bring aboard

Not every wine belongs on a boat. Younger reds with structure, whites meant to be drunk young, Champagne, rosé, and fortified wines (Madeira is bulletproof, it was literally invented on ships) all travel well. Leave the first-growth Bordeaux, the grand cru Burgundy, and anything over fifteen years you actually care about in your land cellar. Bring those down for a specific occasion if you want something special.

The point

Collectors don’t spend decades building their cellars to have bottles cooked by August. What they want is simple: pour something they’ve been looking forward to, in a setting they love at the marina, on a long cruise, anywhere they actually use the boat and have it taste the way the winemaker intended.

That’s the whole goal. The technical details exist to serve it. Get the basics right and those moments, the right bottle, the right people, dinner aboard as the sun goes down, keep happening, season after season.

If you’re considering your next yacht, evaluating a refit, or navigating any decision around the boat you already own, I’d welcome the conversation. The decisions made during a refit show up years later when it comes time to sell. Knowing which choices protect value and which quietly erode it is the kind of perspective most owners only wish they’d had earlier. And when a client needs resources beyond me, I only work with the best in the industry, earned and vetted over the years, because my clients deserve nothing less. That’s the work. The bottles shared and the conversations long after the close, those are the byproducts of doing the job right.
