Simple Syrup
Shelf life 2–3 weeks refrigerated
What it is
Simple syrup is equal parts white sugar dissolved in equal parts water — the most fundamental sweetener in the cocktail pantry. The sugar is completely dissolved into solution, producing a liquid that integrates smoothly into cold drinks without the graininess of undissolved sugar. White caster sugar produces the cleanest result; granulated sugar works equally well with sufficient stirring or gentle heat. Simple syrup can be made cold (stir until dissolved, which takes several minutes) or hot (heat gently until clear, then cool before use).
In the cocktail
Simple syrup is used wherever neutral sweetness is required without additional flavour character — a Daiquiri, a Gimlet, a Whisky Sour. Its neutrality is the point: it balances citrus without competing with the spirit or any other flavoured ingredient. Because it integrates perfectly into cold liquid, it produces a more consistent result than adding sugar directly to a shaken drink, where granulated sugar may not fully dissolve. The 1:1 ratio is the standard; recipes specify their sweetness level assuming this concentration. If you make rich simple (2:1), halve the quantity called for.
Add a small splash of vodka (about 5% by volume) to extend shelf life to 4–6 weeks without affecting flavour. Store in a clean glass bottle with a tight seal — plastic can impart off-flavours over time. Label with the date. Discard if you see any cloudiness or sediment developing.
