Sugar syrup is a liquid sweetener of granulated sugar dissolved in water, used to sweeten and balance mixed drinks.
Cleanly sweet and flavour-neutral, with no aroma of its own and a light to moderately syrupy body depending on the sugar-to-water ratio.
Stirred, shaken or built in, it supplies neutral sweetness and a little body to offset sour and bitter elements, dosed by the barspoon or fraction of an ounce. Recipes assume a specific concentration, so a richer 2:1 syrup delivers more sweetness per measure than a standard 1:1 and will unbalance a build if swapped without adjusting the pour.
Any clean, neutral liquid sweetener that dissolves evenly and delivers comparable sweetness; a coloured or strongly flavoured sweetener such as cane syrup will tint and flavour a drink and loses the plain syrup's transparent neutrality.
Gomme (gum) syrup
Gomme syrup is a sugar syrup with gum arabic added, giving it greater viscosity and a smoother mouthfeel; plain sugar syrup contains no gum arabic.
Bartenders dissolve granulated sugar (sucrose) in water, either heating it or stirring at ambient temperature until clear, to produce a pourable liquid; the standard formulation is a 1:1 ratio of equal parts sugar and water, while a 'rich' syrup uses 2:1 for a thicker, sweeter result. Because sugar does not dissolve readily in cold or spirituous drinks, the pre-dissolved liquid mixes evenly where granulated sugar cannot, and a neutral batch can be infused with herbs, spices, citrus or floral elements to make flavoured syrups.
Perishable once made; keep refrigerated and discard when it turns cloudy or shows mould or floating particles, typically within a few weeks.
