Carbonating
IntermediateAdding CO2 to cocktails using a soda siphon, iSi whip, or forced carbonation system.
วิธีทำ
1. Prepare your fully mixed cocktail, chilled and ready to serve. 2. For a soda siphon: pour the cocktail into the siphon chamber, seal it, and charge with one CO2 cartridge. Shake gently, then dispense directly into a glass. 3. For forced carbonation: transfer the cocktail into a soda bottle or cornelius keg, seal it, and apply 30–45 PSI of food-grade CO2 for 12–24 hours at refrigerator temperature. 4. Release pressure slowly before opening to avoid foam overflow. 5. Serve immediately in a chilled glass without stirring to preserve bubbles. Tip: Colder liquid absorbs CO2 faster and retains carbonation longer — always carbonate chilled liquids. Common mistake: carbonating warm liquid, which results in weak, short-lived carbonation.
เคล็ดลับจากผู้เชี่ยวชาญ
Chill your cocktail to below 38°F before carbonating — cold liquids absorb and retain CO2 far more effectively than warm ones. Use a forced carbonation system at 30-40 PSI for 30 seconds, then release pressure slowly to avoid explosive foaming. Remove all citrus juice and pulp particles before carbonating, as nucleation sites on pulp cause immediate aggressive foaming and CO2 loss. When using an iSi soda siphon, charge with one CO2 cartridge, shake vigorously 5 times, then rest in the refrigerator for 10 minutes before dispensing slowly into a chilled glass.
ข้อผิดพลาดทั่วไป
Carbonating warm liquid results in poor CO2 absorption, producing a barely fizzy drink that goes flat within minutes. Over-pressurizing causes dangerously excessive fizz that erupts violently when opened, spraying cocktail across the bar and wasting the batch. Opening the vessel too quickly after carbonation releases all dissolved CO2 at once in an explosive burst, leaving the drink completely flat and the bar covered in sticky liquid.
