Cold Pressing: Also called (HPP) High Pressure Processing, or Pascalization. Mechanical (hydraulic) pressing of seeds, nuts, plant tissue or animal tissue to express oil without heat, resulting in a pure, highly nutritious juice. This process eliminates any potentially harmful bacteria and maintains the integrity of essential vitamins, minerals, and enzymes. Using this method of High Pressure Processing as opposed to heat, preserves the fresh juice extending its shelf life so it dosent require preservatives.

Why it costs so much:
Cold pressed juices can cost anywhere from 4-10$ for 12oz. The process of cold pressing requires new technology that can be more expensive than traditional methods. As more products are made by these methods, consumer costs will continue to decrease. Another reason it costs so much, it takes many more fruits or seeds or vegetables to make a cold pressed juice than it does to make other types of juice. For example, 2 beets and 5 carrots are in each 12 oz beet apple carrot juice from blueprint.
Starbucks has their own line of cold pressed juices; Blueprint.
Cold pressed juices can be a good way for people who don't like vegetables to still get the nutritional benefits they provide. They can be helpful in treating a variety of minor issues like a hangover or the start of a cold by providing a boost of certain nutrients. Cold pressing preserves the flavors and aromas of fresh squeezed juice. Many people use them for juice cleanses.
While cold pressed juices are high in many vitamins and minerals we need, they are low in fiber and can be really high in sugar if fruit based. Consuming whole fruits and vegetables is definitely healthier because you need the fiber to feel full. While heated pressing may damage or destroy some essential vitamins, minerals and enzymes, it's a more thorough method, extracting a higher portion of the oil than cold pressing.
