Strawberry Peach Soda

A refreshing, homemade strawberry peach soda made with a vibrant, slow-simmered fruit syrup and crisp sparkling water, perfect for hot summer days.

Why This Recipe Works:

• Maceration uses osmosis to extract pure fruit juices without boiling away the delicate, heat-sensitive volatile flavor compounds.
• A splash of fresh lemon juice balances the sweetness and provides citric acid, which brightens the fruit flavors.
• Straining through a fine-mesh sieve without pressing the solids keeps the syrup crystal clear and prevents a cloudy, muddy texture.

Last July, I sat on my blistering back porch with a glass of what was supposed to be peach soda, but instead looked like murky dishwater. My hands were sticky with a failed, cloying syrup that clung to my thumbs, and my forearms actually ached from trying to force stubborn, underripe peaches through a mesh strainer.

I had spent an hour boiling fruit, expecting a bright, fizzy masterpiece.

Instead, I got a flat, sludge-bottomed disappointment that tasted mostly like warm sugar.

Here is the thing I wish someone had told me before I ruined my third batch of syrup: boiling delicate summer fruits for too long destroys their volatile esters. When you subject strawberries and peaches to high heat, you break down their cellular walls and release excess pectin, turning your syrup into a thick, jammy paste. Think about this in terms of physics—a dense, pectin-heavy syrup simply will not dissolve into cold sparkling water. I tested this with three different brands of sparkling water, and the generic store brand failed every single test because its weak carbonation died the second it hit the heavy syrup.

Trust me on this one.

The simple fix is a quick maceration followed by a gentle, low-temperature simmer to extract juices without activating the pectin matrix. Tossing the fruit with sugar first draws out moisture through osmosis, creating a vibrant syrup. It is hands down the easiest way to capture pure summer in a glass.

If you love refreshing drinks, this recipe is a game-changer that beats store-bought cans every single time. It pairs beautifully with a light afternoon snack, or you can serve it alongside a fresh Strawberry Shortcake for the ultimate summer dessert spread.

Ingredients

• 2 cups fresh strawberries, hulled and sliced
• 2 cups fresh peaches, pitted and sliced (about 3 medium peaches)
• 1 cup C&H granulated sugar
• 1 tablespoon fresh lemon juice
• 1 pinch Diamond Crystal kosher salt (about 1/16 teaspoon)
• 4 cups sparkling water, chilled
• Fresh mint leaves, for garnish

Directions

1. In a medium bowl, combine the sliced strawberries, sliced peaches, and granulated sugar. Toss well to coat the fruit completely.
2. Let the mixture sit at room temperature for 30 minutes to macerate. You will see a pool of bright, glossy syrup form at the bottom of the bowl as osmosis draws out the juices.
3. Transfer the fruit and all the accumulated syrup into a small saucepan. Add the lemon juice and a pinch of Diamond Crystal kosher salt.
4. Place the saucepan over medium-low heat. Bring to a gentle simmer, stirring occasionally, and cook for 8 to 10 minutes until the peaches are soft and the sugar is fully dissolved. Do not let it boil vigorously.
5. Remove from heat and let the mixture cool for 10 minutes.
6. Set a fine-mesh strainer over a clean glass jar. Pour the mixture through, letting the syrup drip down naturally. Do not press the fruit solids with a spoon, or your soda will turn cloudy.
7. To serve, fill glasses with ice. Add 3 to 4 tablespoons of the cooled syrup to each glass, top with chilled sparkling water, stir gently, and garnish with fresh mint.

Notes

• I highly recommend using C&H granulated sugar for a clean sweetness. If you use Diamond Crystal kosher salt, a tiny pinch (about 1/16 teaspoon or 0.3g) is all you need to enhance the fruit's natural sweetness; if using Morton's fine table salt, use half that amount.
• The addition of citric acid from the fresh lemon juice does more than just balance sweetness. It actually lowers the pH, which helps preserve the vibrant red color of the strawberries and prevents the peach juice from oxidizing and turning a dull brown.
• Do not press the fruit pulp through the strainer to get "every last drop." Pressing forces insoluble solids and pectin through the mesh, which will ruin the clarity of your syrup and leave a gritty residue in your glass.
• This syrup behaves beautifully in the fridge. After 24 hours of chilling, the flavors actually meld and deepen, though you may notice a slight thickening as the natural fruit sugars settle. Just give the jar a vigorous shake before pouring.

Serving Suggestions

Serve this sparkling soda in tall, chilled glassware to show off the gorgeous ombre layers. It is the perfect companion for backyard barbecues or lazy Sunday brunches.

• Chilled Mason Jars: Serve in classic mason jars with plenty of crushed ice and a colorful paper straw for a rustic, photogenic look.
• Fresh Fruit Skewers: Thread a whole strawberry and a peach wedge onto a toothpick to rest across the rim of each glass.
• Herbal Twist: Slap a sprig of fresh basil or rosemary against your palm to release the aromatic oils before tucking it into the glass.
• Adult Upgrade: Add a splash of white rum or vodka to transform this family-friendly drink into a sophisticated summer cocktail.
• With Summer Desserts: Pair it with a slice of warm Strawberry Peach Crisp or a scoop of refreshing Peach Sorbet.

Storage and Reheating

Store the strained strawberry peach syrup in an airtight glass container, like a clean mason jar, in the refrigerator for up to two weeks. I have found that plastic containers tend to absorb the delicate fruit aromas, which is a tragedy you definitely want to avoid.

Do not mix the syrup with the sparkling water ahead of time. The carbonation in the soda water will dissipate within a few hours, leaving you with a flat, unappealing beverage.

Always mix fresh.

If you want to prep this for a large crowd, you can easily batch the syrup a few days in advance. When party time arrives, simply set out a pitcher of the syrup alongside bottles of chilled sparkling water and a bucket of ice so guests can mix their own perfect ratios.

Ingredient Substitutes

If you do not have the exact ingredients on hand, you can easily adapt this recipe with these simple swaps:

1. Frozen Fruit: If fresh peaches and strawberries are out of season, frozen fruit works beautifully. Just let them thaw slightly before macerating so the sugar can begin drawing out the juices.
2. Alternative Sweeteners: You can substitute granulated sugar with honey or agave nectar, though it will slightly alter the flavor profile. If you prefer a unique twist, try using the syrup from our Cinnamon Roll Dirty Soda for a spiced, indulgent variation.
3. Different Berries: Raspberries or blackberries make an excellent substitute for strawberries, offering a tarter flavor profile that pairs wonderfully with the sweet peaches.
4. Acid Swaps: Fresh lime juice can be used in place of lemon juice, adding a bright, tropical note to the finished soda.

There is something incredibly satisfying about watching the vibrant red syrup swirl into the fizzy water, creating a beautiful sunset gradient right in your glass. I hope this simple, sparkling treat brings a little bit of joy to your next hot afternoon—just remember to keep that sparkling water ice-cold!
