A white Bordeaux blend from Chile, grown on vines that have never needed grafting. The De Martino brothers' Ungrafted project is built entirely on own-rooted vines — scarce, a privilege to farm, and, as the family sees it, the purest possible transmitter of both grape and soil. This one is a Semillón–Sauvignon Blanc off the family's Isla de Maipo vineyard, an old riverbed at the center of the Maipo Valley where the river once split into branches and rejoined (hence "Maipo Island"), leaving alluvial gravels behind. That's a lot of care for a wine at this end of the range, and it shows up as texture rather than oak. The family has been on this land since 1934 and still lives on it — the fourth generation, Marco and Sebastián, farm sustainably and vinify traditionally, on the theory that the place shouldn't be wearing makeup.

"The 2025 Sémillon-Sauvignon Blanc Ungrafted is a 50/50 blend of Sémillon and Sauvignon Blanc from Isla de Maipo that was aged for four months in large oak casks (50 hL). The nose opens with white fruit, herbal notes, ripe citrus and a soft touch of chamomile. Dry and fresh, the palate shows vibrant acidity, energy and a smooth texture. Tasty and persistent, it offers a different take on white wines from the Central Valley." —Joaquín Hidalgo

More about Ungrafted

Ungrafted is named for something only a few wine countries can claim: vines growing on their own roots. Chile has never had phylloxera, so its vines don't need rootstock, and this range from the De Martino family is built entirely from own-rooted vines.

De Martino goes back to 1934, when Italian immigrant Pietro De Martino founded the winery at Isla de Maipo. Fourth-generation brothers Marco Antonio and Sebastián De Martino run it today. It was the first winery to export Chilean Carmenère, in 1996. Around 2011 it dropped new oak and switched to native-yeast fermentation across the range, a big turn toward freshness.

The Maipo wines, Cabernet Sauvignon and Carmenère, come from the family's Santa Inés vineyard on Isla de Maipo, an island where the Maipo River splits, planted on deep gravel left by the old riverbed. The Old Vines Cinsault comes from granite slopes at Guarilihue in Itata, one of Chile's oldest wine regions, where ungrafted vines over 40 years old are worked by hand and horse. Fermentation is with wild yeast, and aging is in older barrels and concrete. The wines are fresh, honest and food-friendly, and great value.

50% Semillon, 50% Sauvignon Blanc

Vineyard

Santa Ines vineyard on Isla de Maipo with some younger vines planted on some prime alluvial soils.

Soil

Gravels and sand with a bit of clay content.

Vinification

Sauv Blanc is fermented in steel and the semillon is fermented in used French oak barrels. The semillon does a partial malo.

Aging

The sauv blanc ages in steel and the semillon in a foudre of 2500 L for 3 months.

Tasting Notes & Food Pairings

Perfect Pairings

Grilled sea bass with lemon and olive oil, ceviche, machas a la parmesana, crab cakes, goat cheese salad with herbs, roast chicken with fennel, or a plate of oysters.

Tasting Profile

Dry and medium-bodied. Aromas run to citrus, fresh-cut grass and a wet-stone note, with a soft, generous texture in the mouth and firm acidity keeping it lifted and clean.
