Soda Water
Soda water is plain water carbonated under pressure, adding effervescence and dilution to a cocktail without contributing sweetness or flavour. It lightens and lengthens spirit-forward drinks. Its neutrality makes it endlessly versatile as a top-up mixer.
Common uses
- tops off built highball cocktails
- lengthens spirit-forward drinks
Buying & storage
Months once opened: Keeps for months once opened, but it does change. Nothing urgent; worth finishing within a season.
Buying: Bottle size beats brand. A small bottle opened fresh always outperforms the last third of a two-litre bottle, and carbonation is the only thing you are buying.
Storage: best used soon after opening, as carbonation fades quickly
In depth
Understanding soda water
How it is made, where it comes from, what it pairs with, and how it behaves in an alcohol-free drink.
How it's made
Water carbonated under pressure, sometimes with a small amount of mineral salts. Carbonation is not a flavour but it is not neutral either: dissolved carbon dioxide forms carbonic acid, which registers as a faint sourness and a physical prickle.
Origin
Artificially carbonated water dates to Joseph Priestley's experiments in the 1760s and became commercially widespread in the nineteenth century — the technology that made the entire highball category possible.
What it pairs with
Lengthens anything without changing its flavour, which makes it the right choice when a drink is good but too intense. Tonic is the better choice when the drink needs bitterness rather than dilution.
In alcohol-free drinks
- The most useful ingredient in alcohol-free drink-making after citrus — bubbles supply both bite and aroma delivery
- A small bottle opened fresh beats the last third of a large one every time, which matters more here than in an alcoholic drink
