This grapefruit simple syrup is gently aromatic with a soft bitterness, balanced by light sweetness. Made with fresh zest and juice, it’s created to add deep flavors to coffee, tea, and sparkling drinks.

Equipment

  • Small saucepan
  • Fine-mesh strainer
  • Citrus zester
  • Juicer or blender
  • Glass bottle or jar

Ingredients

  • 1 cup granulated sugar white
  • 1 cup water filtered or still
  • Zest of 1 grapefruit
  • 1 strip of grapefruit peel
  • 1 cup fresh grapefruit juice (2 medium grapefruits)

Instructions

  • Zest the grapefruit, then remove a strip of peel. Juice the grapefruit using a juicer, or use the blend-and-sift method if needed. Set aside.
  • In a small saucepan over medium heat, combine the granulated sugar and water. Stir gently until the sugar has fully dissolved. Do not increase the heat or allow the syrup to boil.
  • Add the grapefruit zest and peel, then remove the saucepan from the heat immediately. Cover and let the mixture steep for 15–20 minutes.
  • Strain out the zest and peel, then stir in the fresh grapefruit juice.
  • Allow the syrup to cool completely before bottling. This is important, as condensation can affect the syrup’s shelf life.

Notes

This gentle infusion method helps preserve grapefruit’s aromatic oils while keeping the bitterness soft and balanced. If you prefer a lighter bitterness, reduce the amount of zest slightly.
Store in a sterilized glass bottle or jar in the refrigerator. Best used within 2 weeks.
