Orange wine is made by fermenting white grapes as if you were going to make red wine. Specifically, the winemaker crushes her (light colored) grapes and lets the juice ferment with the skins and pulps, which give some pigment as well as tannins (the chemicals in red wine and oversteeped-tea that make your tongue feel dry)
"Orange Wines" aren't necessarily orange, but that have more color than normal white wines, as well as enough texture to pair foods that normal would need red wine. Just how much color and texture varies enormously depending on the grapes, the terroir, and the winemaking.
To help you choose we have categories you can select at the left, including where the wine comes from and what it pairs with.
