Stevia compositions are prepared from steviol glycosides of Stevia rebaudiana Bertoni. The compositions are able to provide a superior taste profile and can be used as sweetness enhancers, flavor enhancers and sweeteners in foods, beverages, cosmetics and pharmaceuticals. The independent claims relate to specific mixtures of rebaudioside A and rebaudioside B. The production process encompasses the steps of incubating stevia sweetener in an alkaline solution at 55-75°C, acidifying and precipitating a stevia composition.
