The Gin Fizz Tropical is a bright, carbonated batch built for 5-gallon keg service — gin, sweet pineapple, and bright lemon concentrate, finished with Angostura Bitters for aromatic complexity. Clean, effervescent, and endlessly sessionable on CO₂.
Four 32oz bottles of Lemonade Concentrate gives this batch the sour backbone to stand up against the pineapple sweetness — it's a properly balanced tropical gin fizz, not a juice bomb. The Angostura at the finish adds depth without muddying the bright, clean profile.
Batch Method
- Add 5 liters Gin to a clean 5-gallon Cornelius keg.
- Add 3 qts pineapple juice.
- Add 4 × 32 oz Top Hat Lemonade Concentrate.
- Add 2 dashes Angostura Bitters.
- Seal the keg and shake vigorously side to side for 2 full minutes.
- Carbonate with CO₂. See instructions below.
- Refrigerate minimum 12 hours before first service.
- Serve ~6 oz over ice. Garnish with fresh mint and a dried citrus wheel.
- Reshake twice daily to re-integrate ingredients.
Pro move: The lemonade concentrate is doing double duty here — sweet-tart balance AND volume. Four full bottles gives you enough acid to cut through the pineapple sweetness. Don't reduce the ratio or the batch tips sweet. The Angostura is subtle but essential — it adds herbal depth that keeps this from tasting like a punch bowl.
- Insert charging stone lid at 45° and spin to align seal. Clamp firmly closed.
- Set CO₂ regulator to 20–25 psi.
- Connect gray/silver Cornelius connector to center plug of charging stone lid.
- Pull up pressure release ring 30 times quickly. Release between each pull.
- Refrigerate 24 hours. Cold liquid absorbs carbonation better.
- Once cold: pull pressure release ring 30 more times.
- Test flow. Reduce to 15 psi if foamy. Maintain 20–25 psi without foam.
