My roaster on 4th told me the same thing last year and I tried it for a month. Honestly I went back to the bag. Here is why. The bag keeps the beans fresher longer, that valve on the side lets the gas out without letting air in. A jar or a hopper just lets them sit in open air and they go stale faster. Unless you are drinking a whole pound in a week, the bag wins. I get wanting to measure and scoop easier, but fresh beans beat easy scooping every time for me.
