Chartreuse Green Recipe

Prepare botanicals

Lightly crush cardamom pods, coriander seeds and cloves with the flat of a knife or a mortar and pestle. Roughly chop angelica root and any fresh herbs to increase surface area. Zest the lemon and orange, taking care to avoid pith.

Combine with spirit

Place all botanicals listed under 'Botanical Maceration' into a clean, large glass jar (minimum 1 L) with a tight-fitting lid. Pour 750 ml high-proof neutral spirit over the botanicals so they are fully submerged. Seal the jar.

Macerate

Store the jar in a cool, dark place. Shake gently once or twice daily for the first 3 days, then once every other day. Taste (diluted) after 3 days: bitterness and green/herbal character will develop. Continue maceration for 7–14 days total depending on desired intensity (7 days for lighter, 14 days for more herbal/bitter).

Strain

When maceration is complete, strain the spirit through a fine mesh sieve lined with cheesecloth into a clean container. Press the solids gently to extract liquor, then discard solids. Optionally filter once more through coffee filter to clarify.

Prepare simple syrup

Combine 250 ml distilled water and 300 g granulated sugar in a small saucepan. Heat gently, stirring until sugar fully dissolves. Do not boil. Remove from heat and cool to room temperature.

Dilute and sweeten

Combine the strained macerated spirit and the cooled syrup in a clean mixing vessel. Stir to integrate. At this stage the alcohol by volume will be lower and sweetness balanced. Taste and adjust: add more syrup for sweeter liqueur or small amounts of distilled water to reduce proof.

Rest and marry

Bottle the blended liqueur in a sealed bottle and rest in a cool, dark place for at least 2 weeks to let flavors marry. Shake gently every few days during the first week.

Optional green color

Traditional Chartreuse gets its green from additional maceration of green herbs. For a natural green tint, blanch 15 g fresh spinach or parsley in 250 ml boiling water for 30 seconds, then plunge into ice water. Blend the greens with a small portion (50 ml) of the cooled blanching water, strain through fine cheesecloth to collect a concentrated green liquid. Add small drops to the bottled liqueur until desired color is reached (start with 5–10 ml). Let sit 1–3 days and re-evaluate color. Note: this will slightly alter flavor and can shorten shelf stability; alternatively, use trace amounts of culinary chlorophyll or spirulina for a very small number of drops.

Final filtering

If the liqueur has any cloudiness after resting or coloring, filter through a coffee filter or fine paper filter to clarify. Transfer to final bottles and seal.

Aging

Age the bottled Chartreuse-style liqueur for an additional 1–3 months for mellower integration. Store in a cool, dark place. Shake gently before serving if any crystals or sediments form.

Serve chilled in a small cordial glass (30–45 ml) as a digestif. It can also be used in cocktails that call for green Chartreuse; replace in equal measure but taste first, as this homemade version may differ in intensity.
