Bosma Estate Winery was born from our love of good wine and interest in growing quality wine grapes. We entered the wine industry in 2005 with the purchase of Bosma Estate Vineyards. More recently we planted Diamondback Ridge Vineyards. Growing quality wine grapes by managing light and water is our focus. Careful attention to details produces top quality grapes which are key to top quality wines.
