Vodka Soda

A vodka soda is simply vodka and carbonated water (club soda or plain seltzer) served over ice, usually finished with a squeeze of citrus. It has almost no calories from sugar, no real flavor of its own beyond the vodka, and depends entirely on using cold, well-carbonated soda water and a decent vodka to taste good. It's the base cocktail bartenders build most other simple drinks from once you add bitters, juice, or flavored syrup.
Varieties
A vodka soda and a vodka tonic are often confused but are not the same drink: soda water (club soda or seltzer) is unflavored and calorie-free, while tonic water contains added sugar and quinine, giving it a bitter-sweet taste and noticeably more calories. A 'vodka soda with a splash of cranberry' is a different, sweeter drink sometimes called a Cape Codder.
Buying tips
Vodka differences matter less here than in a drink with no other ingredients to hide flaws, so a mid-range vodka is usually indistinguishable from a premium one once mixed with soda and citrus. For the soda water, check the carbonation level and buy fresh; soda water that's been sitting open or near-flat noticeably flattens the whole drink.
Substitutes
Gin and soda — 1:1
Same build and proportions, but gin brings botanical flavor (juniper, citrus) instead of vodka's near-neutral taste.
White rum and soda — 1:1
Adds a light sweetness from the rum; works especially well with a lime wedge instead of lemon.
Tequila blanco and soda — 1:1
Turns it into a simple tequila soda (close to a Ranch Water without lime salt); use blanco, not aged tequila, to keep it clean.
Soda water swapped for tonic water — 1:1
Not a substitute for the vodka, but the most common variation: tonic adds sweetness and quinine bitterness, turning it into a vodka tonic.
Non-alcoholic spirit and soda — 1:1
Non-alcoholic gin or vodka alternatives mimic the botanical or neutral base; carbonation and dilution stay the same.
Storage
Vodka itself doesn't need refrigeration and keeps indefinitely unopened; once opened it stays fine at room temperature for years since it has no sugar or perishable ingredients. Soda water is the perishable part of this drink: once opened it goes flat within a day or two even refrigerated, so buy small bottles or cans rather than opening a large one for a single drink.
How to use
The standard ratio is about 2 ounces of vodka to 4 to 5 ounces of soda water over ice, built directly in the glass rather than shaken (shaking or stirring hard knocks out carbonation). Pour the vodka in first, fill with ice, then top with soda water and give it one gentle stir. Add a lime or lemon wedge at the end, not earlier, so the citrus oil stays fresh instead of going bitter sitting in the drink.
What it pairs with
Lime is the standard garnish; lemon works too and is slightly less tart. A few dashes of bitters (orange or aromatic) turn a plain vodka soda into something closer to a mocktail-adjacent highball with real depth. Cucumber slices or fresh mint work well if the vodka soda is being served alongside lighter food like ceviche or a green salad.
Nutrition
A standard vodka soda runs about 95 to 100 calories per serving, almost entirely from the alcohol itself, since plain soda water has zero calories, sugar, or carbs. That makes it one of the lowest-calorie mixed drinks, well below a vodka tonic (which adds roughly 90 extra calories from the tonic's sugar) or a vodka cranberry.
FAQ
What's the difference between club soda and seltzer for a vodka soda?
Club soda has added minerals (like sodium bicarbonate) giving it a very slightly salty edge, while seltzer is just carbonated water with no added minerals; either works fine, though club soda's minerals can round out the drink slightly.
Why does my vodka soda taste flat?
Usually the soda water has lost carbonation from sitting open too long, or the drink was stirred too vigorously; build it gently over ice and use freshly opened soda water.
Is a vodka soda actually low calorie?
Yes, at roughly 95 to 100 calories per standard 2-ounce pour, it's lower than nearly any other mixed drink since the soda water itself contributes zero calories.
Can I make vodka sodas ahead of time for a party?
Not fully mixed, since the soda water will go flat within an hour or two even chilled; instead, pre-portion the vodka into a pitcher or bottle and add fresh soda water to each glass at serving time.
