Bitters and soda is one of the easiest ways to make sparkling water more interesting. Add 4 to 6 dashes of bitters to a tall glass filled with ice, squeeze in a little lemon or lime, and top with about 8 ounces of chilled soda water. Taste before adding any sweetener; a small amount of simple syrup can soften the drink if the bitters and citrus are too sharp.
The result should be lightly bitter, citrusy, and refreshing—not medicinal. Start conservatively, because bitters vary in strength and flavor, and you can always add another dash.
Bitters and Soda Recipe
Yield: 1 drink
Glass: Highball or other tall glass
Equipment: Jigger or measuring spoon, bar spoon, citrus press if using
Ingredients
- Ice
- 4 to 6 dashes aromatic or citrus bitters
- 1 teaspoon fresh lemon or lime juice, optional
- 1/4 ounce simple syrup, optional
- 8 ounces chilled soda water
- Citrus wedge or peel, for garnish
Method
- Fill a tall glass with ice.
- Add the bitters and, if using, the citrus juice and simple syrup.
- Pour in the soda water.
- Stir once or twice, gently, to combine without flattening the carbonation.
- Taste and adjust. Add another dash of bitters for more spice, a little more citrus for brightness, or a small amount of syrup if the finish is too dry.
- Garnish with a lemon or lime wedge, or express a strip of citrus peel over the surface.
How Many Dashes Should You Use?
For a standard tall glass, 4 dashes is a good starting point. Use 5 or 6 when you want the bitters to be the main flavor. If you are using a particularly assertive bitters blend, begin with 2 or 3 dashes and build from there.
A dash is not a perfectly standardized measurement across every bottle and dasher top, so the most reliable method is gradual adjustment. It is easier to add flavor than to correct an over-seasoned glass of soda.
If you are adding citrus juice or sweetener, begin with less bitters than you would use in plain soda water. The additional ingredients change how bitter, tart, and dry the drink tastes.
Choosing the Right Bitters
Aromatic bitters
Aromatic bitters, including the style commonly associated with Angostura bitters and soda, bring baking spice, herbs, and a dry, complex finish. They work well with lemon, lime, ginger, cola, and iced tea. Use these when you want a drink that feels closer to a classic bar mixer than flavored sparkling water.
Citrus bitters
Citrus bitters are a natural choice when you want a cleaner, brighter drink. They pair especially well with lemon or lime and usually need less additional citrus. Try them with plain soda water for a crisp, simple version.
Other styles
Grapefruit, orange, herbal, and spice-forward bitters can all work, but the balance changes from bottle to bottle. Start with a few dashes, then adjust after the drink is carbonated. If the bitters are very sweet, intensely spiced, or strongly herbal, keep the citrus and sweetener restrained until you taste the finished drink.
Four Easy Variations
Lemon bitters and soda
Use 4 dashes of citrus or lemon bitters, 1 teaspoon lemon juice, and soda water. Add a small amount of simple syrup only if the drink tastes too austere. This is a clean option for anyone who wants more brightness than spice.
Lime bitters and soda
Use aromatic bitters with fresh lime juice, or use lime-forward bitters if you have them. Lime can be more pointed than lemon, so start with 1/2 teaspoon and add more as needed. A thin lime wheel makes an uncomplicated garnish.
Bitters, soda, and iced tea
Replace one-third to one-half of the soda water with chilled unsweetened iced tea. Aromatic bitters work well with black tea, while citrus bitters suit lighter teas. Add sweetener only after tasting, since both the tea and bitters may bring their own bitterness.
Bitters and cola or diet soda
Add 2 to 4 dashes of aromatic bitters to a glass of cola or diet soda over ice. The cola already supplies sweetness and acidity, so skip the syrup and use citrus sparingly. Lemon peel is usually enough; a squeeze of juice can make the drink sharper.
How to Keep It From Tasting Medicinal
The medicinal quality usually comes from too much bitters, not enough dilution, or a combination of intense flavors with no balancing element. These adjustments help:
- Start with fewer dashes than you think you need.
- Use plenty of ice and cold soda water.
- Add a little fresh citrus to give the bitterness direction.
- Use only a small amount of sweetener; too much can make the drink heavy rather than balanced.
- Choose one dominant flavor. If the bitters are strongly spiced, keep the garnish simple.
- Stir gently after adding the soda so the drink stays lively.
Fresh soda water matters because carbonation provides much of the drink’s lift. Pour it slowly over the ice, and avoid excessive stirring.
Is Bitters and Soda Nonalcoholic?
Not necessarily. Many cocktail bitters are made with alcohol, even though only a small amount is used in a typical drink. A bitters-and-soda recipe may therefore be low in alcohol rather than alcohol-free. Bitters can also vary by brand and formula.
If you need to avoid alcohol, check the product label and the manufacturer’s current information instead of assuming that a few dashes make the drink nonalcoholic. Follow the guidance that applies to your dietary, medical, religious, or personal requirements. You can also use a clearly labeled alcohol-free bitters product, but its flavor and dash strength may differ from standard cocktail bitters.
The Simple Formula
For an easy starting point, remember:
bitters + optional citrus + optional sweetness + plenty of ice + soda water
Use 4 dashes of bitters, 1 teaspoon of citrus, and 8 ounces of soda water for the first glass. Then adjust one element at a time. More bitters adds depth, citrus adds brightness, and sweetener rounds the finish. The best version is the one that keeps all three in balance without letting any one ingredient dominate.
