Cola Soda Extract Notes Use cola extract as the flavor base in a homemade soda workflow where sweetness, carbonation, and dilution are handled separately. Mix in small test amounts first so the finished soda does not become too strong or too thin. Keep soda equipment clean and pressure-capable when carbonating in bottles, kegs, or other serving gear.
