Established in 1990 by Peter and Emily Gladhart and cared for by the Gladhart family to this day, Winter’s Hill Vineyard prioritizes land stewardship through conservation. The family aims to create a sustainable ecosystem through preservation of the surrounding oak savannah, animal habitats, and prairie lands. The vineyard has been certified by LIVE and SalmonSafe since 1999.

Six long-term employees perform meticulous vineyard practices—including pruning, training, shoot thinning, crop reduction, and multiple passes of tucking—entirely by hand, without the use of herbicides. The pinot blanc vines are more than 30 years old and reside in volcanic Jory soils at approximately 700 feet of elevation.
