Sparkling Wine Tasting Tour

A trio of sparklers after the Mumm Napa tour

Aya Brackett

Best basic sparkling–wine tour: Mumm Napa

An articulate guide covers every aspect of the process in memorable terms; videos give you close-ups of things you otherwise can’t see, like harvesting and the madly foaming surface of a fermenting tank of wine; and cool props show up too, like a wine bottle tacked sideways to the wall that lets you peer at the yeast settled there, flavoring the wine.

Plus, the tour is free.

Most fabulous winery feature: Schramsberg's wine caves

Festooned with lichen and dug deep into the mountain, they evoke the ancient caves of Champagne, France―but are more gothic and mysterious. Stacks of bottles gleam in the dimness as you pass, green lanterns glow overhead, and you may even get to taste by the light of giant candelabra in a moss-perfumed cavern.

This is a place where time seems to have stopped.

Most knowledgeable guide: David Munksgard of Iron Horse

Munksgard, the winemaker, sometimes leads tours himself. He’ll quote Napoleon and reveal the secret to making very tiny, long-lasting bubbles. His good-natured charm and contagious love of sparkling wine come through in everything he says.

And the tour is free.

Loveliest setting: A three-way tie

Korbel Champagne Cellars (pictured), for its soaring redwoods and view of fields and mountains.

Iron Horse, for its rustic freestanding bar fashioned from long planks, where you taste wine under an open roof right next to undulating vineyards.

Schramsberg Vineyards, for the lush beauty of its mountain foliage and the way its dark redwood buildings disappear into the forest.
