100% Chardonnay

Born and raised in Colombia, Martin Bernal-Hafter’s winemaking craft is deeply rooted in agriculture, conservation, and a little dash of magic.

After his first career in finance, Martin and his wife uprooted their lives and moved to Rhone to learn to make wine. Next stop was Mendoza, where Martin served as protege to Paul Hobbs. He followed Hobbs back to Sebastopol, and eventually partnered with Roger Peng to create Alta Orsa—which pairs regenerative farming practices with a strong sense of place, and a healthy dose of wonder.

Light, bright, earthly yet divine – we’re big believers in Alta Orsa’s delightfully balanced Cali-style Chardonnay.

One 250 millileter can of wine is equivalent to a third of a bottle of wine.

The can art is an ode to the wine inside and Martin's winemaking philosophy – blending golden, yellow hues with and element of nature.

Oysters, salmon salad, or creamy brie.

Using holistic farming techniques, Alta Orsa crafts wines that are good on the planet and good on the palate. This 100% Chardonnay was grown at Hafner Vineyard – no herbicides, fish-friendly, Sonoma County sustainable certified, and vegan. The Brix at harvest averaged 22.6. The wine was aged 1/2 neutral oak and 1/2 stainless steel with minimal sulfites added. The wine was kept on lees for 6 months with a little bit of lees stirring and no malolactic fermentation.

The final product is light and racy yet balanced, with citrus and mineral notes.

It’s the kind of wine to enjoy on a clear 70-degree afternoon while sitting in a garden with friends.
