I purchased a large bottle of Pom pomegranate juice at Costco. It was in the refrigerated case. I got home and put it in my pantry (which is in the bsmt and cooler than the rest of the house...) and a week later realized that it was to be kept refrigerated. It was unopened. Is this safe to consume or should I just go ahead and boil it down to make a lovely pomegranate syrup?
