Maine has a legacy of hardworking laborers known for their humble pride. Here, lobstermen pull traps from the icy Atlantic, construction teams build houses in the snow and students in the state\u2019s northern reaches take \u201cpotato recess\u201d to help their families harvest.\r\n\r\nFor winemakers, that determination has driven them to seek out fruit that can withstand the harsh winters.\u00a0While local wineries account for just 2% of the state\u2019s wine sales, hybrid grapes like Marquette, Frontenac and Cayuga are doing their part to boost numbers.\r\n\r\nLess than 75 acres planted\r\n31 wineries participate in the Maine Wine Trail\r\nThe average annual temperature in Maine is\u00a0 45.65\u02da\r\nChesuncook, a coarse loam left by the glaciers, is Maine\u2019s official soil\r\n\r\n\u201cThe good news over the past 10\u201315 years is the progress on these hybrids have allowed the vineyards in Maine to become much more productive than years prior,\u201d says Bettina Doulton, owner of Cellardoor Winery. \u201cSeveral of us have also planted L\u2019Acadie Blanc, which does incredibly well in Maine.\u201d\r\n\r\n\r\n\r\nAlong with Cellardoor, Dragonfly Farm & Winery is using hybrid grapes extensively, as well as making wine from cold-weather-loving Concord grapes. Savage Oakes Vineyard & Winery has also found success, with 10 grape varieties and hybrids, and it\u2019s getting innovative in its use of co-ferments with other fruits.\r\n\r\nCommon Grapes \r\nMar\u00e9chal Foch, L\u00e9on Millot, Cayuga\r\nCorot Noir, Frontenac, Frontenac Gris\r\nMarquette, St. Croix, La Crosse, St. Pepin\r\n\r\nRun by a husband-and-wife team, Elmer and Holly Savage, Savage Oakes was a farm for 200 years before the pair got into winemaking. Elmer takes advantage of both the rich soil and his agricultural degree to produce 90% of their wines from estate-grown fruit, mostly grapes and blueberries.\r\n\r\n\u201cI believe that wine from estate-grown fruit does give you a bit more sense of place than fruit sourced elsewhere,\u201d says Elmer.\r\n\r\nWineries to Know\r\nBar Harbor Cellars, Cellardoor Winery, Dragonfly Farm & Winery\r\nEighteen Twenty Wines, Savage Oakes Vineyard & Winery\r\nUrban Farm Fermentory, Winterport Winery\r\n\r\nAt Eighteen Twenty Wines in Portland, Owner Amanda O\u2019Brien found that rhubarb wine has been well received, given its subtle rose-like notes. Plus, it\u2019s easy to grow.\r\n\r\nWinemakers in Maine may have individual approaches to the perfect glass, but they arrive there in the same trial-and-error fashion.\r\n\r\n\u201cEach winery is run so differently, but one thing is for sure: They are all run with grit,\u201d says O\u2019Brien.
