Farming & winemaking at union vineyard
FARMING—
Organic | no-till | dry farmed
Six acres of pinot noir comprise the entirety of Union Vineyard. The vines are organically farmed and, owing to the thin layer of topsoil at the ridgeline on which the vineyard is planted, a native cover crop is maintained to reduce erosion. The roots of the mature vines penetrate the sandstone of the Santa Cruz Mountains and absorb moisture deep underground rather than depending on a constant diet of surface irrigation water. This dry-farming approach develops flavor in the grapes while restricting yields, and in turn conserves the aquifer. The viticulture here has sustained 160 years of winemaking and these practices promote the expression of this singular piece of ground.
WINEMAKING—
Whole-cluster | concrete teacups
Spontaneous fermentation may begin within a week, slowly building from the carbonic maceration of the first few days. No yeast, acid, water, or enzymes are added; the only ingredient is pinot noir. Fermentations are carried out in the ambient temperature of the cellar without glycol cooling or heating. Following fermentation the young wine is drained by gravity to barrels where it remains for a year and a half until bottling barrel-by-barrel. No pumps are used and the wine is not filtered. These winemaking choices minimize the influence of technology, allowing for clear expression of the vineyard and the growing season.
Our imperative is to bottle a wine that could only come from this place. Very little winemaking happens. The wine is allowed to be itself, to tell the story of this place with its own unique flavor.
Wild yeast and the fruit, left alone in the teacups for a month or so—that’s the winemaking. Gravity moves the wine from teacup to barrel. A year and a half later we put the wine in bottle. That’s it. It’s an honest proposition and inevitably the wine is vivid and singular, each year differing with the season.
