The Mojito is one of the most requested summer cocktails — and batching it properly on CO₂ keeps the mint bright, the lime fresh, and the carbonation consistent through extended service.

The challenge with batch mojitos is keeping the mint flavor bright without it oxidizing. This batch solves that by using mint concentrate rather than muddled fresh mint, delivering consistent flavor at volume.
Batch Method
- Add all spirits and concentrates to a clean 5-gallon Cornelius keg.
- Add remaining ingredients and top with cold filtered water to 5-gallon volume.
- Seal the keg and shake vigorously side to side for 2 full minutes.
- Carbonate using CO₂ charging stone method. See panel below.
- Refrigerate minimum 12 hours before first service.
- Serve ~6 oz over ice in appropriate glassware. Garnish as desired.
- Reshake twice daily to re-integrate settled ingredients.
Pro move: Do not add fresh mint to the keg — it oxidizes and turns the batch bitter within hours. Use mint in the concentrate or as a garnish only.
🍺 CO₂ Carbonation — Carbonated Draft Cocktail
- Chill all ingredients to 36–38°F before batching (cold liquid carbonates better).
- Add all ingredients to a clean 5-gallon Cornelius keg. Seal tightly.
- Connect CO₂ "gas in" connector. Set regulator to 20–25 psi.
- Lay keg on its side and roll back and forth for 2 minutes to carbonate.
- Pull pressure release ring 30 times to purge and re-charge with CO₂.
- Refrigerate 24 hours before first service for best carbonation.
