No preservatives, no pausterizing, no HPP.  All of our juices are cold-pressed and have a tamper proof seal that will have a "created on" date as well as an "enjoy by" date.  They must be refrigerated and are best enjoyed 3-5 days after creation. We do not aim to extend shelf life by adding artificial preservatives or by using pasteurization methods such as high pressure processing (HPP). We believe a raw juice should remain raw.
