Welcome to Mansfield-Dunne

Mansfield-Dunne Wines is the culmination of a 10 year effort of John and Lynn Peterson to secure land in the Santa Lucia Highlands with the goal to grow premium pinot noir and chardonnay and produce wine from those grapes.  We are committed to producing small quantities of artisan crafted wine from meticulously farmed, Estate Grown grapes. 

Our current releases – the 2015 Mansfield-Dunne Peterson Vineyard designate pinot noir and chardonnay and 2015 Mansfield-Dunne Santa Lucia Highlands appellation pinot noir – come entirely from our family owned Peterson Vineyard. 

Starting with the 2016 vintage we are also producing pinot noir, chardonnay, and syrah from our newly planted Cortada Alta Vineyard.  The new vineyard is the highest higher elevation property in the Santa Lucia Highlands.  The initial Cortada Alta wines will be released later in 2018
