I was surprised at the subtle sweetness of this cranberry concentrate. I have purchased other concentrates as well as reconstituted quart bottles, and they all are much more tart and not as flavorful as the Dynamic Health brand. I kept looking at the ingredient list to see if a sweetener had been added, and there is none. For those of you who avoid pure cranberry juice because of the tartness, try this brand. iHerb packages well and delivers promptly. I bought 5 bottles for the best shipping rate, enough to share or keep me in stock for awhile.
