We go further to ensure your safety. Our products are made in a class 100 clean room and are cold sterile filled. What does this mean? First, our bottles are sterilized and taken into a room devoid of oxygen. Next, moments after being flash pasteurized, each luscious drop is poured into our unique, custom-designed bottles. As an extra precaution, we flush the top with nitrogen before capping, to prevent oxygen from entering. So you might hear a little psst when you open the cap. Just like you and I need oxygen, so do most microorganisms. If this weren't enough, we've specially lined our bottles and caps to protect each tantalizing drop during transport. We think we are doing a good job. Where our competitors typically have <100 ppm of bacteria in their bottle, ours are an undetectable <1, even after 60 days on the shelf.
