With cereal grasses or for that matter any superfood like gogi, noni, acai the type of product is really not the discussion point that matters. What really matters is whether or not this is a living or dead food. If it is pasteurized, canned, dried or powdered it is a dead food. You just can't process things and give them a shelf life without doing a lot of damage.
With wheatgrass juice, that means the preferred method would be fresh...except for one important problem. Most wheat grass is grown in trays, greenhouses or environments that are too hot. When the environment is overly hot, it causes two problems. The first is that when any plant is stressed, it seeks to procreate (seed) as fast as possible. Wheatgrass grown in hot environments is stressed and grows in just 10 days instead of at least 120 days in a natural outdoor environment. The second problem is that the heat also promotes the growth of mold and mold happens to have a life cycle that often peaks just as you want to harvest your wheatgrass. Mold is a challenge because it is responsible for the negative side-effects you read about on the internet. It also happens to make wheatgrass juice taste bad. If your wheatgrass juice is tough to drink, trust your instincts and avoid it.
So what we want is a living food, produced by a plant that lives a natural life cycle and is free of molds. The only way to do this is to grow outdoors and flash freeze the juice. This keeps is living and makes it available 365 days a year and does so without compromise according to our customers.
