Long coffee enjoyment: Coffee emits CO2, which can negatively affect its aroma. The secure canister lid not only protects your coffee from light and moisture, but the CO2 release valve also eliminates the emitted CO2 from the canister. This way, the natural flavor is preserved, and you can always enjoy the best coffee. Integrated calendar sheet: Turn the calendar wheel to record, for example, the opening date of the filled coffee beans. Multifunctional: Of course, the elegant stainless steel canisters are not only suitable for storing ground coffee or fresh beans; tea, cocoa powder, spices, and much more can also be safely stored in them. Each canister has a capacity of 1.9 liters, suitable for approximately 500 grams of beans or ground coffee.
