Can oranges be fermented into alcohol?

Wednesday, November 5, 2025
Yes, oranges can absolutely be fermented into alcohol. Like grapes, apples, and berries, oranges contain natural sugars that yeast can consume and convert into ethanol. The process is straightforward: juice the oranges, add a fermenting yeast strain, and allow it to work for several days to weeks in a controlled environment. 

The result can range from a light, citrusy wine to a tangy, orange-based liqueur. Because oranges have high acidity and unique aromatic compounds, their fermentation often produces bright, zesty flavors that carry over beautifully into the finished drink.

In truth, almost any fruit containing sugar can be fermented into alcohol. Apples become cider, grapes become wine, plums become slivovitz, and cherries can transform into rich liqueurs like kirsch. Even honey, technically not a fruit, forms the foundation of one of humanity’s oldest fermented beverages: mead. 

The principle is universal. 

If yeast can find sugar, it will create alcohol. 

The differences come from the sugar levels, acidity, and flavor compounds inherent to the base ingredient.

Oranges are often blended with other fruits or honey to balance their tartness during fermentation. For instance, an orange-honey mead or a mixed fruit wine can soften the sharp citrus edge while enhancing complexity. 

Breweries and home winemakers sometimes use orange zest or peel in beer or wine fermentation, adding aromatic oils that deepen flavor without introducing too much acidity. 

Even in distilling traditions, orange peels and juices find their way into spirits like Grand Marnier and Cointreau, showing how versatile the fruit is in alcohol production.

At the most basic, improvised level, fermentation happens anywhere sugar and yeast meet, even unintentionally. In prisons, for example, inmates often make “pruno,” a crude homemade alcohol created by fermenting fruit (including oranges), sugar, and bread yeast in sealed containers. 

Though far from refined, it works because the process obeys the same laws of biology that craft brewers use every day. Whether in a stainless-steel fermenter or a plastic bag, the chemistry is the same. Sugar, yeast, time, and a little curiosity, that’s all it takes to turn an orange into alcohol.
