Natural citrus seltzer is incredibly refreshing on a warm day. This week the thermometer has climbed above 80°F in parts of California, unusually warm for winter. I grew up drinking Coca-Cola, but as I got older I realized soda wasn’t the best choice for daily refreshment. What I missed most was the bright fizz of sparkling water. During a five-week exchange in France in high school I discovered Orangina — unlike orange Fanta or many fruit sodas, Orangina tasted like real oranges, wasn’t overly sweet, and felt truly refreshing. When I first tried frozen citrus juice cubes, that same fresh, natural flavor came back to me.
I used to buy natural, low-sugar fruit-flavored seltzers, but now I make my own soda water with a home carbonation device. It gets heavy use in warm months. During citrus season I also make frozen juice cubes to add to seltzer. Juicing fruit and freezing it is simple, and yet it’s one of those easy hacks many people haven’t tried. Often a friend will mention it and I’ll have that small epiphany: why not make your own?
Tips
When guests visit, I offer sparkling water with citrus juice ice cubes. Most people prefer that over plain soda unless they dislike citrus. If you have citrus trees, buy fruit on sale, or just want a healthy way to dress up your seltzer, try this natural citrus seltzer. It’s low-effort, flavorful, and visually appealing.
How to juice
I use an electric juicer and always strain out any pits or excess pulp for a smooth, clear juice. Pour the strained juice into ice-cube trays and freeze. If you prefer, silicone trays or smaller molds work well for bite-sized cubes. While some refrigerators include built-in ice makers, basic ice-cube trays are inexpensive and easy to find.

Storage for frozen juice cubes
After the juice is fully frozen, pop the cubes out of the trays and transfer them to freezer-safe bags or airtight containers. Label the bags with the date; frozen citrus cubes keep well for several months, though flavor is best within a few weeks.

To serve, fill a glass with chilled or carbonated water and add several citrus juice cubes instead of flavored syrups. The cubes slowly melt, adding fresh juice and brightening the drink without excess sweetness. Try combinations like orange-lime, grapefruit-lemon, or a mix of several citrus fruits for a layered flavor. Garnish with a fresh twist of peel or a sprig of mint for an extra touch.
