Ingredients

  • 2 large grapefruits (for zest only, avoid the white pith)
  • 1 tablespoon gentian root (the bitter base)
  • 1 teaspoon cardamom pods (crushed)
  • 1 teaspoon coriander seeds
  • 1 cinnamon stick
  • 5 cloves
  • 1 small piece of dried orange peel
  • 1 cup high-proof vodka (at least 80 proof, for extraction)
  • 1/4 cup water
  • 1 tablespoon sugar (optional, to balance bitterness)

Equipment

  • Sharp vegetable peeler or zester
  • Glass jar with a tight-fitting lid (at least 16 oz capacity)
  • Fine mesh strainer or cheesecloth
  • Small funnel (for bottling)
  • Amber dropper bottles (for storage)
  • Measuring spoons and cups
  • Mixing spoon

Instructions

  1. Prepare the grapefruit zest. Using a vegetable peeler or zester, carefully remove the outermost layer of the grapefruit peel. Avoid the white pith underneath, as it can add unwanted bitterness. Set aside the fresh zest.
  2. Toast the spices. In a dry skillet over medium heat, lightly toast the cardamom pods, coriander seeds, cinnamon stick, and cloves for 2-3 minutes until fragrant. This step helps to release their essential oils and deepen the flavor.
  3. Combine ingredients in the jar. Place the grapefruit zest, toasted spices, gentian root, and dried orange peel into your glass jar. Pour the vodka over the ingredients, ensuring everything is submerged.
  4. Seal and shake. Close the jar tightly and give it a good shake to mix the contents. Store the jar in a cool, dark place for 10-14 days, shaking it once daily to promote infusion.
  5. Strain the mixture. After the infusion period, strain the liquid through a fine mesh strainer or cheesecloth into a clean container, pressing gently to extract as much liquid as possible.
  6. Make the simple syrup. In a small saucepan, combine the water and sugar. Heat gently until the sugar dissolves completely, then allow to cool.
  7. Combine bitters and syrup. Add the simple syrup to the strained bitters liquid, stirring well. This step is optional but recommended to soften the intense bitterness and round out the flavor.
  8. Bottle and store. Using a funnel, transfer your grapefruit bitters into amber dropper bottles. Store in a cool, dark place. Your bitters will keep for several months, even up to a year.

Tips & Variations

“Patience is key when making bitters—allowing the full infusion time brings out the best flavors.”

  • Adjust bitterness: If the bitters are too strong, add more simple syrup or dilute with additional vodka.
  • Experiment with spices: Try adding star anise, black peppercorns, or dried hibiscus petals to customize your bitters.
  • Use other citrus: Substitute grapefruit with blood orange or lemon peel for different flavor profiles.
  • Longer infusion: For a more intense flavor, infuse for up to 3 weeks, tasting every few days.
  • Sweetener alternatives: Use honey or maple syrup instead of sugar for a unique twist.
