Do you use sulfur dioxide during the processing of your grape skin extracts?

Unlike enocianina grape skin extracts from Europe, Polyphenolics does not add sulfur dioxide during the extraction of our grape skins. Therefore, Polyphenolics’ GSKE and GSKE-40 skin extracts contain less than 100 ppm and 75 ppm of sulfur dioxide, respectively, while competitors’ extracts may contain up to 5500 ppm of sulfur dioxide.
