Time Out says
This elixir is made with wheatgrass, one of the most popular ingredients in cold-pressed juice and a great cleanser of the blood, liver and bowels. You may not like the green color of the juice or the bitter taste of the wheatgrass, but this is one of Mercy Juice's bestsellers, so you’ve gotta try it. The blend of green grapes, kiwi and apple provide sweet and sour notes, leaving a tiny bit of lingering astringency at the end. This is a healthy and tasty way to replenish your body with water and vitamins. It is the perfect vegetable juice for beginners.
