Meet The Team

Dave & Joan Kroupa

Founders

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.

Mike Altesleben

Winemaker

Mike joined the team at Peninsula Cellars in January 2020.  Originally from the Detroit area, he moved to Traverse City in 2010, in pursuit of his passion for wine.  Mike paid his dues in the vineyard to understand the unique terroir of Old Mission Peninsula. Eventually, he worked his way into the cellar and up the ranks to take on head wine making responsibilities.  Mike studied Viticulture at Michigan State University and Oenology at Washington State University. When he’s not in the cellar, he enjoys spending time with his family and friends, BBQing, and enjoying the outdoors.
