I’ve just put some new coffee in my product and can’t create a vacuum, why?

For the first 3 to 5 days after roasting, coffee beans release a lot of CO2 gas. If this happens inside the product it can hinder the vacuum process by eliminating the negative pressure. However, Ankomn products are specially designed to keep air out even in this situation, so your coffee will be kept fresh. Once the coffee stops releasing CO2 and stabilizes then the vacuum will continue to work as normal for you.
