William's Soda Extracts are the finest available, for a rich, old-fashioned flavor. One 4 ounce bottle (and 3 pounds of corn sugar or equivalent) will make 3 gallons of rich non alcoholic soda using the traditional mix and carbonate method. Or even better, keg and inject C02 for a more even and predictable carbonation level.
Safety Warning: If you bottle condition with champagne yeast, use plastic PET bottles, as glass bottles could explode, causing personal injury. Carbonating with yeast can be unreliable, and some batches may turn out flat, while others can be overcarbonated.
