Real limoncello is made from sfusato amalfitano lemons — football-sized, thick-skinned, intensely fragrant citrus that grow ONLY on the terraced cliffs between Amalfi and Capri. The peels are soaked in pure alcohol for 40+ days, then mixed with sugar syrup. The result is CLOUDY, thick, intensely lemony, and nothing like the neon-yellow industrial bottles sold at airport duty-free. Real vs fake: Real limoncello is opaque (pectin from the peels makes it cloudy). Fake is crystal-clear (made with lemon flavoring, not peels). Real tastes like biting into a lemon. Fake tastes like lemon candy.

Step 1: Peel the lemons — ONLY the yellow zest (no white pith — pith = bitter). Step 2: Soak peels in 96% pure alcohol (alcool per liquori) for 30-80 days in a dark, cool place. The alcohol extracts the essential oils. Step 3: Strain. Dissolve sugar in water (simple syrup). Combine with the infused alcohol. Step 4: Bottle. Rest 2+ weeks. Serve ice-cold (store in freezer — limoncello doesn't freeze due to alcohol content). Drink in a frozen glass after dinner — a digestivo tradition on the Amalfi Coast.
Customs: US: 1 liter of alcohol per person duty-free. Limoncello is ~30% ABV. EU: No limit within EU. UK: 1 liter of spirits (limoncello qualifies). Packing: Wrap in bubble wrap + place in checked luggage center (surrounded by clothes). OR: Buy at duty-free at the airport (no packing worry). BUT: Airport duty-free limoncello is usually INDUSTRIAL. The real stuff comes from the producers listed above.
