(BangorDailyNews) - When Elmer and Holly Savage started growing grapes here 10 years ago, there were only a handful of wineries in Maine. Now there are eight wineries in the midcoast area alone. The area seems to be at the center of the state’s burgeoning wine industry — despite, not because of, its profitability. The Savages — owners of Savage Oakes in Union — are one of the only businesses in Maine to grow, process and sell their own wine. “Our grapes travel 300 feet from picking to product. Maybe a bit farther,” Holly said as she stood on the sunny, south-facing hill where her grapes grow.
