No, orange wines aren’t made from oranges, they are white wines that are a result of very unusual production process.
White wines, compared to red ones, are fermented without contact wth skin. The grape juice is separated from skin during the squeezing of the juice and this two parts never see each other again.
In a new winemaking trend, the grape juice from the white grapes is allowed to ferment some or full time with the grape skins. Grape skins contain tannins as well as natural colour and flavour compounds, that are passed to the grape juce. When left to ferment with the skins, the wine becomes less transparent and become yellow in the colour, later turning to the orange hues.
Wines created that way are more full bodied, with more pronounced aromas and flavours. They are mostly made dry.
What differences them from classic white wines, apart from colour and aromas are the tannins. Standard white wine can have tannins that result from aging in an oak barrels, but don’t have them from the skins.
Orange wines are very complex and therefore not recommended for the begginers, but after some time spent in tastng wines, they are worth trying, becouse of expanding popularity among wine community.
