Rainbow Flavors of Osage Beach, Missouri, has been making old fashioned soda extracts for over 30 years now, and they use the finest natural and artificial ingredients in their extracts. Their extracts are so good that many brewpubs across the country use their extracts in making their on-tap root beer and other sodas.
One 2 ounce bottle (and 4 pounds of household cane sugar) will make 4 gallons of rich soda using the traditional mix and carbonate method. Or, you can mix them fresh to taste with our Seltzer Bottle (see link below) adding a teaspoon of extract and some sugar to a glass before adding the carbonated seltzer and ice. You can also carbonate with dry champage yeast (see link below), although this can be unreliable, and should only be done iin plastic bottles to prevent possible injury.
Soda Extracts include instructions for carbonating with dry champage yeast. 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.
