Dave and Joan Kroupa are the founders of Peninsula Cellars. As lifelong cherry farmers, Dave and Joan saw the need to diversify their fruit farming operation. They began planting vineyards in select sites on the farm in 1991, and quickly realized that opening a winery was the next step to securing the future of the farm. In 1994, the first vintage of Peninsula Cellars wine was released. Joan is currently involved in the day to day book keeping and financial planning for Peninsula Cellars. Sadly, Dave passed away in January of 2021, but his legacy of hard work and determination is forever ingrained in the culture of Peninsula Cellars.
