I have been using ACV for years and go thru a quart per month. Last year I returned 4 bottles of ACV to the store that I bought it because it was sour. There is a distinct difference in taste between a sour apple and a fermented apple. After the second time, I called the company and they did not seem alarmed or really that interested.......just told me to carry it back where I purchased it. Well I got tired of having to carry it back after the fourth time and have been using other brands and have not ran across this problem again. My experience was with one of the oldest and most widely used brands out there.
