The Heineman Winery is the oldest family-run winery in Ohio (founded in 1888 by Gustav Heineman). Located on the island of Put In Bay, Ohio, Heineman Winery is a very popular tourist destination. Not only are they a winery, they also are home to Crystal Cave, the world's largest geode! Crystal Cave was discovered by workers in 1897 while digging a well for the winery 40 feet above. Heineman Winery offers tours of both the cave and the winery. The Heineman family really needed a new website that was fully responsive to mobile devices as well as giving them the ability to sell their wines online. Truevine crafted for them a true gem of a website with full eCommerce capability!
