For 12 years, Loren Shanle worked as an independent insurance agent out of a small office on Walnut Street in Rochester, just south of Rochester Station. By spring, Shanle hopes to have the roughly 1,000-square-foot space converted into a winery that doubles as an infrared sauna retailer. He plans to make the wine on-site, using juices and concentrates from vineyards across the world, and will offer wine-tasting as well as winemaking equipment.
