Pure Cane Sweetened Soda Recipe

Combine and dissolve

In a small saucepan combine 1 cup granulated pure cane sugar and 1 cup filtered water. Stir gently to moisten the sugar before applying heat so it dissolves evenly.

Heat to clarify

Place the saucepan over medium heat. Bring mixture to a gentle simmer, stirring occasionally, until the sugar is fully dissolved and the liquid is clear (about 3–5 minutes). Avoid a rolling boil — you want a steady simmer to prevent caramelization.

Add acid and flavor

Once the sugar is dissolved and clear, remove from heat. Stir in 1 tablespoon fresh lemon juice (this keeps the syrup from crystallizing and brightens the flavor). If using vanilla bean, scrape seeds into the syrup and add the pod now; if using extract, stir in 1/2 teaspoon pure vanilla extract.

Cool and strain

Allow the syrup to cool to room temperature (20–30 minutes). If you used a vanilla pod or any solids, strain the syrup through a fine mesh sieve into a clean jar. Seal and refrigerate. Syrup will keep 2–3 weeks refrigerated.

Chill components

Ensure your sparkling water and simple syrup are chilled. Cold liquids retain carbonation better and produce a crisper soda.

Measure and taste

For a balanced sweetness start with 1/4 cup (60 ml) of the simple cane syrup per 1 liter of sparkling water. Pour the syrup into a large pitcher or bottle, then slowly add 1 liter of chilled sparkling water to preserve fizz.

Adjust sweetness

Stir gently once or invert the sealed bottle gently to combine. Taste and adjust: for a sweeter soda add additional syrup by tablespoons; for a lighter soda reduce to 2–3 tablespoons per liter.

Serve

Fill glasses with ice if desired. Pour the soda over ice, garnish with a lemon wheel, lime wedge, or fresh mint to taste. Serve immediately for best carbonation.

Batch scaling note

Simple syrup is concentrated 1:1. Use the ratio of 60 ml (approx. 1/4 cup) syrup per 1 liter sparkling water as a baseline. Scale the syrup quantity proportionally for larger or smaller volumes.
