This flavor is just like the flavor of apple now and later, jolly rancher, or any other sour apple candy. It is not sour on it's own; you would have to add malic acid to recreate the sour part. If you want the taste of fresh apples, look elsewhere.
I finally found a realistic, fresh, tasting apple. The best part is I only had to use 1% solo for a great taste. I look forward to using it with other flavorings for some great bakery type, and fruit mixes. Caramel apple ... yummy
