Jeff Malkiewicz, President & Co-Founder

After growing up in Metro-Detroit and graduating from Michigan State University, Jeff moved to San Francisco to follow his career in banking. Corporate America quickly grew stale and he yearned to open a business to produce a product he believed in. When Jeff was touring a local distillery in Northern Michigan, he recognized the need for a local malt house to serve the area’s acclaimed breweries and spirit providers. He took the idea and ran with it. Jeff happily resides in Traverse City with his wife, Kerry, and two dogs, Levi and Finn. Always the jokester, Jeff loves New Yorker Cartoons, sampling new beers and spirits, hiking and spending time on the lake with friends and family.
