Homemade Blood Orange Soda: 76 Cents a Glass

Blood oranges show up for a short season, look dramatic, and disappear just as I remember why I love them. The bottled blood orange sodas ride the same wave at boutique prices. So this October I juiced the fruit myself, built a syrup that keeps the color and the bite, and costed the glass honestly. It comes out at 76 cents, deep red, tart first and sweet second, which is the order bottled versions always get backwards.

The syrup: juice, zest, and restraint with sugar

For one batch I use 6 blood oranges, which at my Knoxville grocery this month were 60 cents each, so 3 dollars and 60 cents of fruit. Zest two of them before juicing, then juice all six for roughly a cup and a half. Simmer the juice with the zest, three-quarters of a cup of sugar, the juice of half a lemon, and a pinch of salt for five minutes, just until the sugar dissolves. Off the heat, stir in half a teaspoon of vanilla. Do not boil it hard or long: cooked citrus goes dull and brownish, and the whole point of this soda is that electric red. Strain, chill, and keep it cold. The batch makes about 2 cups of syrup, enough for 8 glasses at 2 ounces each.

The build

Fill a tall glass with ice, add 2 ounces of blood orange syrup, and pour in 10 ounces of sparkling water. Stir once, gently. Taste before you add anything: blood oranges vary, and a tart batch needs nothing while a sweet batch wants an extra squeeze of lemon in the glass. A thin wheel of orange on the rim is not garnish for its own sake, it is how your nose reads the drink as fresh before the first sip. For an evening version, a sprig of rosemary rubbed between your palms over the glass adds a piney note that works far better than it sounds.

The honest cost math

Here is the batch at my local store-brand prices, disclosed so you can re-price it at yours. Six blood oranges at 60 cents are 3.60 dollars, and each glass uses a syrup share of one-eighth of the batch, so 45 cents of fruit per glass. The sugar, lemon, and vanilla for the whole batch come to about 1 dollar and 4 cents, or 13 cents a glass. Sparkling water at my store runs about 18 cents for the 10 ounces in each glass. Total: 45 plus 13 plus 18 is 76 cents a glass. The craft bottled blood orange soda on the same shelf was 7 dollars for a 4-pack, which is 1 dollar and 75 cents a bottle. One batch of syrup, about 6 dollars and 10 cents all in with the water, replaces 14 dollars of bottles.

Mistakes I made so you do not have to

My first batch used a full cup of sugar and tasted like candy; blood orange needs its acidity left alone, so start at three-quarters and adjust in the glass, not the pot. My second mistake was carbonating with warm syrup over no ice, which killed the fizz on contact. Cold syrup, cold water, plenty of ice. Third: regular navel oranges are not a silent substitute. They make a fine orange soda, but the berry-like edge and the color are the entire reason for this recipe, so wait for the real fruit or make a different soda that week.

FAQ

How long does blood orange syrup keep? About two weeks refrigerated in a clean sealed jar. The color fades slightly after the first week, so drink the prettiest glasses early.

Can I use bottled blood orange juice? You can, and it is still cheaper than bottled soda, but you lose the zest oils and some brightness. Add a strip of fresh orange zest to the simmer to recover part of it.

Why add lemon to a citrus syrup? Blood oranges can be low-acid compared with lemons. A little lemon sharpens the flavor and helps the color stay vivid in the glass.

What if my oranges are very sweet? Cut the sugar in the next batch to two-thirds of a cup and add the lemon first. Sweetness is easy to add in the glass and impossible to remove from the pot.

Can I make it with a home carbonator? Yes. Chill the syrup and water separately, build the drink still, then carbonate gently, or simply use the carbonator for the water as I do here.
