Napa

Why go

The tasting that changed wine — Napa cabernet beat Bordeaux blind in Paris in 1976. Terroir in a small space — sixteen sub-appellations in a thirty-mile valley, from Carneros fog to Howell Mountain. Winery architecture — from a Rhône-style castle to Herzog & de Meuron's stone gabion walls at Dominus. A serious table — the valley's restaurants trained a generation of American cooking.

The character

The Napa Valley is thirty miles long and rarely more than five wide, sheltered between the Mayacamas and Vaca ranges, and its whole viticultural logic is fog. Cold air comes off San Pablo Bay at the southern end, holds the mornings, and burns off by ten, giving hot afternoons and cold nights — the diurnal swing that gives cabernet its structure. Move north toward Calistoga and it gets hotter; move up the hillsides and the soils turn volcanic and thin. Sixteen sub-appellations in a space you can drive in an hour.

Wine was made here from the 1860s, wiped out by phylloxera and Prohibition, and rebuilt after the war by a small group of growers who believed the valley could make wine at the level of Bordeaux. In 1976 a British merchant organised a blind tasting in Paris and Napa won both the red and white flights, a result French judges disputed for years. That afternoon converted an agricultural district into a global reference, and everything since — the château-building, the cult cabernets, the crowds on Highway 29 — follows from it. The valley's current challenge is not quality but fire: three major seasons in the last decade have made smoke taint a permanent part of the conversation.

Places of character

The Silverado Trail — the quieter eastern road; drive this rather than Highway 29. A small tasting room where the person pouring made the wine; book ahead, they are appointment-only by law. Dominus Estate — Herzog & de Meuron's basalt gabion building, visible from the road even without an appointment. Oakville Grocery — a country store since 1881, and the correct place to assemble a picnic. Calistoga — the northern end, with mud baths and geysers from the same volcanic activity that shaped the soils. Yountville — three blocks with more Michelin stars per head than anywhere in America.

The way to do it

Book everything — Napa tastings are by appointment, and drop-ins mostly do not exist. Three wineries a day is the maximum that leaves you able to taste. Hire a driver or nominate one seriously; the law is strict and the roads are not forgiving. Go north as the day warms, spit more than you swallow, and buy from the small producers who will never reach a shop where you live.

One perfect day

Coffee in Napa town, then north on the Silverado Trail before nine to a hillside cabernet producer with a morning appointment and a view down the valley through the last of the fog. Second tasting mid-morning at a small family estate — no château, a barn, a dog. Picnic from Oakville Grocery under an oak. Afternoon at one architectural winery for contrast, then an hour in Calistoga in a mud bath, which is the local answer to a day of tannin. Early dinner in Yountville — the long tasting menu if you booked three months ago, the bakery and bistro if you did not — and back before dark down the valley with the vineyards turning blue.

Grand hotels

Auberge du Soleil — on the eastern hillside above Rutherford since 1981, with the terrace that sold the world on Napa. Meadowood — a private estate in an oak canyon behind St Helena, croquet lawns and all.

When to go

Best expression: September and October, harvest, warm days and the valley smelling of fermentation. Consider: March and April, mustard flowers between the vines, half the visitors, easier bookings. Avoid if possible: high summer weekends on Highway 29, and the late-season weeks when wildfire smoke is a genuine risk.
