Fountain Sodas Recipe

chill and portion

Chill the carbonated water thoroughly (best if under 40°F / 4–6°C). Measure out syrups into individual small pouring containers or ramekins so each soda can be built quickly and without cross-contamination.

prepare glasses

Fill each serving glass with about 1 cup of ice cubes. If you prefer less dilution, use crushed ice or omit ice and chill the glass instead.

Classic cola (1 serving)

In a 16- to 20-ounce glass over ice, add 2 tablespoons (about 1/8 cup) cola syrup. Pour 1 cup chilled carbonated water slowly down the side of the glass to preserve fizz. Stir gently one time with a long spoon to combine. Garnish with a lemon wedge or a maraschino cherry if desired. (If using the listed 0.25 cup cola concentrate total, this makes 2 servings; scale as needed.)

Lemon-lime soda (1 serving)

In a glass with ice, add 2 tablespoons lemon-lime syrup. Slowly add 1 cup chilled carbonated water, stirring gently once to combine. Squeeze a wedge of lime into the drink and drop the wedge in as garnish.

Orange soda (1 serving)

In a glass with ice, add 2 tablespoons orange syrup. Add 1 cup chilled carbonated water slowly, stir gently once, and drop an orange slice into the glass for aroma.

Cherry or vanilla variations

For a cherry cola: add 1 tablespoon cherry syrup to the cola before adding carbonated water. For a vanilla float-style soda: add 1 teaspoon vanilla syrup to the cola or root/cream base. Adjust to taste; add a maraschino cherry on top.

Mixing blended flavors

To create mixed fountain flavors (e.g., half cola + half lemon‑lime), add 1 tablespoon cola syrup and 1 tablespoon lemon‑lime syrup into the glass, then add 1 cup carbonated water and stir once. Taste and adjust syrup amounts in 1 teaspoon increments if needed.

Serve immediately after building to preserve carbonation. If syrups are stored, keep refrigerated and use within the manufacturer’s recommended timeframe. For a sweeter or stronger soda, increase syrup by 1 tsp at a time; for a lighter soda, reduce syrup or add more carbonated water.

If using fountain equipment: typical draw ratios range from 1:5 to 1:8 syrup to water depending on syrup concentration—calibrate your machine per syrup manufacturer. Always flush lines and chill water to avoid flat, warm soda.
