Russian River Valley

Jackass Vineyard

The older of the two Martinelli home plots, planted before 1889 on the rolling apron below the homestead at the foot of Jackass Hill.

History

Giuseppe Martinelli planted this ground within a few years of arriving from Tuscany, making it one of the oldest continuously producing vineyards in North America. From the early 1980s until 1992 Williams Selyem held exclusive rights to its fruit, and the Williams Selyem Jackass Vineyard Zinfandel became one of the founding wines of the modern heritage-vine movement before the family reclaimed the fruit for the estate.

The Site

Four to five acres of rolling bench at the base of the hill, where shale debris washing off the slope gathers into slightly deeper loam. The vines are visible from above as individual head-trained dots rather than wire rows.

Vines and Blocks

Dry-farmed, head-trained Zinfandel on St. George rootstock, planted in the 1880s.

The Wines

Estate Jackass Vineyard Zinfandel is the structured, black-fruited counterpart to the hill above it, carrying the same century-old concentration with a shade more flesh from the deeper ground.
