In fact, about 10,000 tons of "wine pumice," which refers to the skins and seeds of grapes left over after squeezing during winemaking, are discarded annually. We started to commercialize this product in order to make effective use of this material. Wine pumice is rich in polyphenols and is also effective in anti-aging. This new product can be used to make a variety of ingredients, including regular vegetables, tomatoes, avocados, tofu, and cheese, delicious just by adding water.
