Many people use jute bags, but their main disadvantage is that they are porous. Through the pores, coffee loses moisture and absorbs foreign odors. To solve this problem, we have developed unique GRENVIA bags. Inside our bags, there is a sealed plastic bag with a zipper. This prevents coffee from coming into contact with the environment, helps it retain moisture for longer, and protects it from fungus or mold. GRENVIA bags are the most optimal and reliable option for storing and transporting coffee beans.
