Miller Ranch

Miller Ranch enjoys bay breezes and silty, cool, and deep soils that are ideal for growing Chardonnay, Sauvignon Blanc and Semillon.

A mile or so south of Yountville, a quiet lane runs East towards the Napa river, crossing Hopper Creek on its way. It skirts land of subtle contours with rich alluvial soils. It was here that David and Sarah Dunlap settled in the mid-1870s to plant plums, pears and wine grapes. Almost exactly one century later, Ron and Diane Miller made this their Napa Valley home.

The vineyard is in a climate sweet spot: cool enough in the mornings and not too warm in the evenings. The resulting Sauvignon Blanc has refreshing aromas of grapefruit, lime and tangerine. The Chardonnay from here adds nice notes of golden apple, spice and pear to our Estate Grown Chardonnay blend.

Most of the Chardonnay plantings flank the banks of the Hopper creek where we have done considerable work to ensure that the water is clean and cold as it makes its way between the town of Yountville and the Salmon spawning grounds in the Napa River. We are very proud that both the California State Assembly and the United States House of Representatives have cited our efforts for Land Stewardship here on Miller Ranch.
