Simple Syrup for Cocktails (1:1 vs. 2:1)

200 g (1 part by weight)

Standard syrup — white granulated sugar — Caster sugar dissolves faster but any fine white sugar works

200 ml (1 part by volume)

Standard syrup — water — Filtered water; mineral water can add a faint flavor

400 g (2 parts by weight)

Rich syrup — white granulated sugar — Requires brief heat to fully dissolve at this concentration

200 ml (1 part by volume)

Rich syrup — water — Hot water (not boiling) used to achieve complete dissolution

1 tsp per 250 ml

Optional: gum arabic — Converts standard syrup into gomme syrup; adds silky body without additional sweetness

Standard 1:1: Combine equal weights of sugar and water in a clean bottle, seal, and shake until all sugar dissolves (at room temperature, fine sugar dissolves in about 2 minutes). No heat required. Rich 2:1: Dissolve sugar in hot (not boiling, ~70°C) water on the stove, stirring constantly, then cool before bottling. Avoid boiling as it can caramelize the sugars and introduce an amber tint. Both can be made cold if you allow 10–15 minutes of shaking; cold-process 2:1 is slower but avoids any thermal flavor change. Store refrigerated in a sealed bottle.

• Rich 2:1 syrup requires half the volume of standard syrup to achieve the same sweetness — always adjust pour volume when switching between concentrations
• Standard 1:1 refrigerated shelf life is 2–3 weeks; rich 2:1 lasts 4–6 weeks because the higher sugar concentration inhibits microbial growth
• Adding a few drops of vodka (2–3% of total volume) extends shelf life of either concentration by another week without affecting flavor
• Never boil the syrup — sucrose can partially invert (splitting into fructose and glucose), which creates off-flavors and changes sweetness character
• For high-volume bar use, 2:1 is preferred because the smaller pour volume means one bottle goes further and the pumps are calibrated in smaller increments
• Color is an indicator of concentration: 1:1 is water-clear; 2:1 has a very faint viscous gleam when you tilt the bottle
• Cold-process (no heat) 1:1 is indistinguishable in flavor from cooked; cold-process 2:1 takes longer and may leave trace undissolved crystals — shake vigorously

• Demerara syrup (2:1)

  Demerara sugar instead of white; adds molasses notes and amber color; used in Ti' Punch, Old Fashioned riffs, rum cocktails

• Turbinado syrup (1:1)

  Coarser raw sugar at standard ratio; slightly more mineral and caramel flavor than white

• Honey syrup (3:1)

  Three parts honey dissolved in one part warm water to lower viscosity; used in Bee's Knees, Gold Rush

• Agave syrup (2:1 or 3:1)

  Agave nectar thinned with water; lower glycemic index; used in Margarita and Paloma riffs

• Gomme syrup

  1:1 simple syrup with 1% gum arabic added; creates extraordinary silky mouthfeel; traditional in 19th-century cocktails

• Flavored simple syrups

  Fresh herbs, spices, or zest steeped in finished 1:1 syrup off heat; lavender, rosemary, jalapeño, cinnamon, cardamom are common

• Daiquiri (2:0.75:0.75)

  Classic daiquiri calibrated for 1:1 syrup; halve the syrup pour if using rich 2:1

• Whiskey Sour (2:1:0.75)

  Uses simple syrup as the sweetener; ratio assumes 1:1 concentration

• Pisco Sour (3:1:1:0.5)

  Simple syrup at 1:1 concentration is the canonical choice; rich syrup shifts the balance noticeably
