Syrups and Cordials

Level: Beginner6 min readEditorial draft

Syrups are the backbone of balance: simple 1:1, rich 2:1, agave and piloncillo. Cordials add acid and flavor so one component brings both sweetness and sourness.

Simple and rich syrup

Simple syrup is 1:1 sugar to water by weight; rich syrup is 2:1. Weighing instead of measuring by volume is the easiest path to consistency.

Rich syrup adds body, dilutes less and keeps longer. If you swap one for the other in a recipe, adjust the amount: rich syrup is sweeter per milliliter.

Agave and piloncillo

Agave nectar is very thick; cutting it with water (for example 2:1 or 1:1 agave to water) makes it easier to measure and mix. It's sweeter than sugar, so start with less.

Piloncillo is grated or broken up and dissolved in hot water, 1:1 by weight to start. Add cinnamon, orange peel or anise for a café de olla-style syrup. Strain out any impurities.

Cordials

A cordial combines sugar, flavor (peels, fruit, herbs) and acid. Citric acid gives a bright, lime-like sourness; malic acid tastes more like green apple. Many bartenders blend both.

Add acid gradually and taste diluted, as it would be served in the drink. It's easy to overshoot.

Brix basics

Degrees Brix express the percentage of dissolved sugar by weight. A 1:1 syrup sits around 50 °Bx and a 2:1 around 66 °Bx.

A refractometer lets you check every batch, adjust fruit juices that vary by season and repeat recipes accurately.

Equipment

  • Scale
  • Pot or blender
  • Fine strainer
  • Clean bottles with lids and labels
  • Refractometer (optional)

Key variables

Sugar-to-water ratio
1:1 (≈50 °Bx) or 2:1 (≈66 °Bx) by weight.
Temperature
Heat speeds dissolving, but a long boil evaporates water and shifts the ratio.
Acid in cordials
Start low and build gradually; always taste diluted.

Process

  1. 1

    Weigh the sugar (or piloncillo) and water for your chosen ratio.

  2. 2

    Dissolve: cold in a blender for simple syrup, or with gentle heat (no hard boil) for rich and piloncillo syrups.

  3. 3

    For cordials, infuse the flavor and add acid at the end, little by little.

  4. 4

    Strain and let cool.

  5. 5

    Measure Brix if you have a refractometer and record it.

  6. 6

    Bottle, label with name, ratio and date, and refrigerate.

Storage

Refrigerated in clean, sealed bottles. Use a fresh bottle for each batch; never top up old syrup.

Shelf life

As a conservative guide: 1:1 simple, around two weeks; 2:1 rich somewhat longer. Syrups with fresh fruit or herbs keep less. Label and date; if it turns cloudy, smells off or shows mold, discard.
