Limoncello

Ingredients

• 5-7 organic lemons
• 300 ml grain alcohol (95% ABV)
• 700 ml water
• 500 ml sugar

Method

Limoncello is an infusion built on one principle: volatile lemon oils dissolve in alcohol, not water. Use grain alcohol at 95% ABV — anything weaker won't extract the aromatics efficiently. Peel the lemons with a vegetable peeler or zester, taking only the yellow zest and leaving every scrap of white pith behind. The pith is bitter limonin, and it will creep into the spirit over weeks and flatten your finish. Submerge the zest in the alcohol in a glass jar — mason jars work, but a kilner jar with a rubber seal is better because it keeps oxygen out. Seal it completely and store in a cool, dark place.

The infusion phase takes 20 days minimum. Don't shake the jar daily; this is passive aromatic-infusion, not fermentation. After three weeks, hold the jar to a light source. The liquid should have shifted from clear to pale gold and smell intensely of lemon — almost solvent-like at first, then softening into sweet citrus. This is when the essential oils have migrated fully into the alcohol. Strain the zest out through a fine sieve, pressing gently to extract the last drops of oil-laden spirit. Discard the zest.

Make a simple syrup by dissolving 500 g caster sugar in 700 ml water. Heat until the sugar dissolves completely — roughly 65°C — then let it cool to room temperature. Never mix hot syrup with spirit; the heat volatilises the aromatic compounds you've spent weeks building. Once cool, combine the two liquids and stir gently for two minutes to ensure even distribution.

The final ABV should sit around 28–30%, which you can verify with a hydrometer if you're scaling up. Bottle in glass and store in the freezer. Serve in chilled glasses as a digestif, or in a carafe at the table — the cold suppresses the burn and amplifies the citrus oils on the nose. It keeps indefinitely under freezing conditions; the alcohol content prevents spoilage.
