Clementine Wine

CLEMENTINE WINE

Clementines are the overachievers of the citrus world — sweeter than a tangerine, more delicate than a navel orange, and packed with fragrant oils in that thin, easy-to-peel skin. When you ferment them, you get a pale, floral wine with a bright citrus nose and a clean, slightly tart finish. A full five-pound box goes into just one gallon, so this is an all-in kind of wine. It rewards patience: give it a full year in the bottle and it transforms from sharp and raw into something genuinely worth pouring for company.

The beginner trap: Skipping the tartaric acid or swapping it for citric acid or acid blend — clementines have a naturally high pH, and without tartaric acid specifically, fermentation can stall and the wine will taste flat.

Ingredients

• 5 lbs (1 box) clementines, fresh
• Zest from 5–7 of those clementines
• Juice from 5 small Valencia oranges (or any fresh-squeezed orange juice, about 1 cup)
• 1½ lbs granulated white sugar
• 7 pts (3.5 quarts) water, divided
• ¾ tsp tartaric acid (find it at homebrew shops or online — do not substitute)
• ¼ tsp wine tannin (or 1 cup unsweetened strong-brewed black tea)
• 1 tsp yeast nutrient
• ½ tsp pectic enzyme
• 1 Campden tablet, crushed fine
• 1 packet wine yeast (Lalvin 71B or EC-1118 work well; Gervin B if available)

Method

1. Zest 5–7 clementines before peeling, then peel and segment all of them, removing every bit of white pith as you go.
2. Cut each segment in half and place the cut fruit and zest into a nylon mesh straining bag; tie it closed and set it in your primary fermenter (a food-grade bucket).
3. Bring half a gallon of water to a boil and dissolve the sugar completely in it; pour this hot syrup over the bagged fruit.
4. Add the orange juice, tartaric acid, tannin, and yeast nutrient to the fermenter, then stir in the remaining cold water.
5. Cover the fermenter and let it cool to room temperature (around 65–75°F).
6. Once cooled, sprinkle in the pectic enzyme, stir gently, re-cover, and wait 12 hours.
7. Activate your yeast according to packet directions, then add it to the must; cover the fermenter loosely to allow gas to escape.
8. Stir the must once a day until the specific gravity drops to 1.010 (usually 5–7 days).
9. Lift the bag and let it drip drain into the fermenter — do not squeeze it; discard the pulp.
10. Dissolve the crushed Campden tablet in a small amount of wine, stir it into the liquid, then transfer everything to a one-gallon glass jug (secondary fermenter).
11. Top up to the shoulder of the jug with water or reserved wine if needed, fit an airlock, and let fermentation finish to dryness.
12. When bubbling stops, rack the wine off the sediment into a clean jug, top up, and refit the airlock.
13. Rack again every 60 days for 6 months, topping up each time.
14. Taste the wine — if it is too tart, add a stabilizer (potassium sorbate plus a Campden tablet), sweeten lightly to taste, wait 3 weeks, then bottle.
15. Age in the bottle for at least one year before opening.

Why this works

Clementines sit at a higher pH than most winemaking fruits, which is a problem because yeast and the wine’s long-term stability both depend on a low-acid environment — ideally pH 3.4–3.6. Tartaric acid is the right tool here because it is the most stable of the common wine acids; it does not get metabolized away by bacteria the way malic acid can, and it doesn’t leave the sharp edge that citric acid sometimes does. The pectic enzyme is equally important: citrus is loaded with pectin, the same stuff that makes jam gel. Without it, your finished wine will be hazy no matter how long you wait. The enzyme breaks those pectin chains apart so the wine can eventually clear on its own.

Notes

Valencia orange juice adds body and rounds out the flavor — any fresh-squeezed orange juice works as a substitute, but avoid bottled juice with preservatives, which can inhibit fermentation. This wine is best kept under 12% ABV, so resist the urge to add extra sugar. Serve well chilled.
