In 2014, Matt and Kelly Austin left their careers as an attorney and fashion designer in California for a new life in the Pacific Northwest. After Matt returned to school to study enology and spent time working with several Washington wineries, he stumbled upon the auction of a small vineyard on the Southside of the Walla Walla Valley. Planted with uncommon varieties, these first 5 acres became Grosgrain Vineyards, a winery dedicated to organic farming and wines of freshness and elegance. The development of a subsequently acquired 80-acre property has allowed them to expand a range of grape varieties. Located on a small hilltop just above the Walla Walla Valley floor at an elevation of 785 feet, Old Milton Vineyard is the site of the winery, tasting room and vacation rental, Casa Grosgrain. The property is planted to Nebbiolo and Aglianico, which were existing plantings, as well as Grenache and Carignan planted in 2018. The soils consist of deep and well-drained Walla Walla silt loam.
