Coffee and Caffeine FAQ

I would say probably not. There is an argument that the vacuum storage will cause the beans to out gas faster due to the pressure but I'm not sure that will override the advantage of removing oxygen. The one suggestion I would make is that you store 2-3 days worth of coffee in a container ans store your coffee in multiple containers. If you put everything in a big jar and vacuum the air out just to open it up every day you will reintroduce oxygen thus destroying much of the advantage of vacuum storage.
