WHY MAKE IT
A little comfort, a lot of flavor.
Mulberries possess a complex sweet-tart profile with deeper earthy undertones than standard blackberries or raspberries. Cooking the berries briefly into a light reduction softens their fibrous structure, intensifies their natural sweetness, and concentrates their dark color. Combined with fresh spearmint and strained lemon juice, the berry base becomes bright and aromatic. Effervescent club soda dilutes the rich syrup into an invigorating sparkling cooler suitable for hot afternoons. This recipe balances natural fruit tannins with refreshing carbonation and herbal aromatics, offering an elegant nonalcoholic drink without artificial colorings or flavorings.
Mulberry Selection and Preparation
Black or deep purple mulberries provide the richest color and most balanced sugar-to-acid ratio. Fresh mulberries typically retain a tiny green central stem; while soft enough to eat, removing prominent stems produces a cleaner reduction. If using frozen mulberries, do not thaw them beforehand; add them straight to the saucepan with the sugar and water. As they warm, the berries release juices that dissolve the sugar into a thick syrup.
Technique for Straining and Infusing
Straining the warm reduction through a fine-mesh sieve removes the soft pulp fragments and tiny seeds, creating a smooth liquid that blends seamlessly into sparkling beverages. Pressing with the back of a ladle maximizes yield without forcing gritty solids through the mesh. Chilling the syrup before shaking ensures the ice in your shaker does not melt excessively, which would dilute the berry flavor before the club soda is even introduced.
Carbonation and Herb Pairings
Club soda contains mineral salts that slightly soften the acidity of fruit beverages, providing a rounder mouthfeel than plain seltzer. Spearmint complements the dark fruit notes of the mulberry reduction by contributing menthol top notes. Tearing the leaves by hand rather than cutting them prevents bruising along cell walls, ensuring the mint releases volatile oils rather than bitter compounds into the finished drink.
Before you start
Mulberry juice stains porous cutting boards, countertops, and clothing quickly. Use glass, stainless steel, or ceramic tools when working with the fresh or cooked fruit. When bruising the mint in the shaker, do not over-muddle; shaking with ice extracts the fragrant essential oils from the mint leaves while preventing bitter chlorophyll from overpowering the nuanced, dark berry flavor of the reduction.
THE RECIPE
Sparkling Mulberry Mint Cooler
4 servings · 10 minutes preparation · 8 minutes cooking · 30 minutes cooling, chilling or resting
Ingredients
Step-by-step instructions
- In a medium stainless steel saucepan, combine 2 cups black mulberries, 1/3 cup cane sugar, 1/4 cup water, and 1/4 cup lemon juice over medium heat.
- Bring the mixture to a simmer, stirring frequently and crushing the berries against the bottom of the pan with a wooden spoon for 8 minutes until the berries soften and the liquid thickens into a syrup.
- Press the hot mulberry mixture through a fine-mesh sieve into a heat-safe bowl to remove skins and small seeds, yielding approximately 1 cup of smooth reduction.
- Cool the reduction at room temperature for 10 minutes, then refrigerate for 20 minutes until thoroughly chilled.
- Place the 16 torn spearmint leaves and the chilled mulberry reduction into a beverage shaker filled with ice; shake vigorously for 10 seconds to infuse mint aroma without completely pulverizing the leaves.
- Strain the mixture evenly into four 12-ounce glasses filled with crushed ice (about 1/4 cup reduction per glass), top each glass with 3/4 cup chilled club soda, stir gently, and garnish with fresh mint sprigs.

Storage & make-ahead
Keep the strained mulberry reduction in a sealed glass jar in the refrigerator for up to 5 days. For longer storage, freeze the reduction in ice cube trays for up to 2 months. Never combine the club soda in storage; add carbonation only upon assembly. Discard any drinks left at room temperature over 2 hours.

Frequently asked questions
Can I substitute blackberries for mulberries?
Yes, blackberries can be substituted in equal measure. Keep in mind that blackberries are generally more tart and have firmer seeds, so you may need to add an extra tablespoon of sugar and strain firmly.
Why shake the reduction with mint instead of muddling in the glass?
Shaking with ice extracts mint oils cleanly into the syrup and chills it instantly. Muddling directly in the glass often tears mint into small bits that clog drinking straws and impart bitter herbal notes.
Can I use seltzer water instead of club soda?
Yes, plain seltzer water or sparkling water works well. Club soda has added mineral salts like sodium bicarbonate that subtly soften fruit acidity, but seltzer offers a clean, crisp alternative.
