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. 

We have been producing Pinot Noir and Chardonnay from our family owned Peterson Vineyard since the 2010 vintage.  Starting with the 2016 vintage we have also been producing Pinot Noir, Chardonnay, and Syrah from our newly planted Cortada Alta Vineyard.  The new vineyard is the highest elevation property in the Santa Lucia Highlands appellation.

Our current releases include five vineyard designate wines (2017 Cortada Alta Vineyard Pinot,  2017 Cortada Alta Vineyard Chardonnay, 2017 Peterson Vineyard Pinot, 2017 Peterson Vineyard Chardonnay, and 2016 Cortada Alta Vineyard Syrah), as well as our 2017 Santa Lucia Highlands appellation Pinot.
