Grand Marnier Recipe

Prepare peels

If using fresh Seville oranges, wash and dry them. Use a vegetable peeler or microplane to remove the outermost orange zest only (avoid white pith as much as possible). If using dried bitter orange peel, ensure it is clean and roughly chopped to increase surface area.

Place the cognac or brandy in a large, clean glass demijohn or jar. Add the prepared orange peels to the spirit so the peels are fully submerged.

Seal the container and macerate in a cool, dark place for 10–14 days, gently swirling the jar once daily to help extract oils. Taste periodically; the spirit should take on bright orange aromatics and some bitterness from the citrus oil.

Make sugar syrup

Combine the granulated sugar and water in a saucepan. Warm over medium heat, stirring until the sugar fully dissolves. Bring to a gentle simmer for 2–3 minutes to ensure clarity, then remove from heat and cool to room temperature.

If you want a slightly richer mouthfeel like commercial Grand Marnier, use a 1:1 sugar-to-water ratio as above. For a drier finish, reduce sugar to 250 g and water to 300 ml. If using the optional orange extract or distillate, stir it into the cooled syrup to boost orange aroma.

After the maceration period, open the jar and remove the orange peels. Strain the cognac through a fine-mesh strainer lined with cheesecloth into a clean vessel to remove any particulate. Gently press the peels to extract remaining spirit but avoid squeezing out bitter pith.

Split the vanilla bean and scrape the seeds into the strained orange-infused spirit; add the pod as well. This step mimics the subtle vanilla notes in Grand Marnier. Allow to steep for 24–48 hours, then remove the pod and filter again if needed.

Combine the cooled sugar syrup with the orange-infused cognac. Start by adding about 300 ml of syrup, stir and taste. The target is a balanced liqueur with noticeable orange aroma, sweet but supported by the cognac backbone. Commercial Grand Marnier is roughly 40% ABV and about 30% sugar by weight; you can adjust syrup quantity to reach desired sweetness and viscosity. If the final spirit is too strong, add more syrup; if too sweet, add more cognac. If using optional orange distillate, a few drops can be added now for brightness.

Bottle the liqueur in sterilized bottles, seal tightly, and rest for at least 2–4 weeks to allow flavors to marry and any harsh edges to mellow. Store in a cool, dark place. Before serving, chill or serve at room temperature over ice, use in cocktails, or sip neat as a digestif.
