Our Story

Wine brings people from different walks of life together. We hope that when you leave our tasting room you not only find a new wine that you love, but also leave with new friends and memories.

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 Vineyard. 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.
Over years of growing wine grapes and developing our new vineyard, we became interested in the clonal variations within the varieties. As a result there are 6 different clones of Cabernet Sauvignon and 2 different clones of Malbec planted at Diamondback Ridge Vineyard.
We make very small batch wines, keeping the clones separate from harvest through bottling so that the wine consumer can experience these same differences. Though the nuances are small, they are very discernable. By sourcing the grapes from our estate vineyards where we can control the growing conditions and terroir, we can then control for all winemaking variables such as yeast, type of barrel, age of the barrel, toast of the barrel and length of time in the barrel, thereby highlighting just the clonal differences between the grapes.
Our first releases – 2017 Viognier, 2017 Roussanne, and 2016 Syrah – have since sold out, and we have added over a dozen wines to our cellar since we opened our doors.
