The story of SummitVine is one of evolution – a journey that begins with the discovery of raw land and eventually leads to creating the extraordinary wines we all know as “SummitVine”!


SummitVine Ranch is the project that Michael and Susan Klopka had dreamed of, providing not only a wine country lifestyle, but also the opportunity to be involved in the wine growing industry. Initially, their goals were quite modest, but things quickly took on a life of their own, and SummitVine Ranch has since grown into a successful farming operation with two distinctive hillside vineyards: Cori’s Vineyard and Sophie’s Vineyard, both named after two very special dogs that have their paw prints deep in the soil of SVR.



In addition to attending UC Davis viticulture classes and being deeply involved and active in day-to-day farming operations, Michael consults with top professionals on best practices for producing the finest fruit possible. SummitVine Ranch fruit has been the source for highly acclaimed single vineyard wines since their first harvest in 2004 and continues today under our SummitVine label. With the 2013 harvest, our inaugural vintage focused on the flagship wine that Diamond Mountain is best known for, Cabernet Sauvignon. Since then, we have expanded our products to include a second wine sourced from the Bordeaux varietals in Sophie’s vineyard – thus creating a Bordeaux style Red Wine Blend.

Our focus will remain the same for every wine we craft: selecting the best fruit from select vineyards and drawing out the unique characteristics of those grapes. Each of our single-vineyard designated wines is very limited in production and a rare opportunity to experience what we call “SummitVine”.

The first vineyard was planted in 2001 and by 2004 the fruit was so extraordinary that a winery, with that vintage, started an eight year run making an award winning, vineyard designated, “SummitVine Ranch” Cabernet Sauvignon.  The contract changed hands and some of the fruit now finds itself in a flagship Diamond Mountain AVA wine from an award-winning winery.
