Named in honor of a massive 400-year-old chestnut tree that once dominated the winery's courtyard, the estate was founded in 2014 by Luciano Ronzero with just two hectares of vines which straddle the villages of Donnas and Pont St Martin. Taking advantage of the sandy soils and unique high elevation microclimate at 1,600 feet above sea level, the estate is dedicated to the employment of natural farming methods. No herbicides or irrigation are used, and all work must be done by hand given the steep terrain.
