The secret to kegging and force carbonating soft drinks is to carbonate most of the water first; the sugar content makes it more difficult to carbonate the finished beverage. 

DAY 1: Prepare the Keg and Water 

  1. Clean and sanitize your keg. 
  2. Place 3 gallons of cold water into the keg. 
  3. Seal the keg and pressurize by setting your CO2 regulator to 25 pounds. 
  4. Shake the keg until you no longer hear gas running from the regulator. 
  5. Refrigerate the keg under pressure for 24 hours. 

DAY 2: Make the Syrup and Extract

  5. Release the pressure on the keg and open the top.
