Formula and rules
- Sugar : water is measured by weight: 1:1 for simple, 2:1 for rich syrup
- Water = sugar ÷ ratio; sugar = water × ratio
- Granulated sugar measures about 0.85 g per ml, so 200 g takes about 235 ml of volume
- Yield ≈ sugar volume + water volume; dissolving contracts the mixture slightly
- A typical cocktail uses 15 ml (½ oz) of syrup

FAQ
How long does simple syrup keep?
A 1:1 syrup keeps about two to three weeks in a sealed jar in the fridge. Rich 2:1 syrup has less water, so it lasts three to six months the same way.
Can I make it with cold water?
Yes, but it takes longer. Shake it in a closed jar until no crystals are left, or use hot water off the heat — boiling the syrup for minutes changes the flavour and adds water.
Why do bartenders use rich syrup?
Rich syrup brings the same sweetness with about half the water, so a cocktail keeps its strength and body instead of tasting diluted. It also keeps much longer once opened.
