ORANGE WINE: "any white wine that's on the skins for more than three days." Orange wine, also known as "skin-contact wine," is made by letting the grape juice ferment with the skins and the seeds of the grape. it picks up qualities associated with red wine, like tannins, which can lend "rich, honeyed flavors that are at times nutty, with a vibe similar to sherry," as Miller said. But it can also turn out "yeasty and sour and cloudy."
The wine word VDN stands for "Vin Doux Naturel," and it's a specific style of wine produced in certain parts of France. VDN wines are sweet fortified wines made using a process called 'mutage', or the addition of grape spirit during fermentation.
