Yep like FC says those beans gotta be fresh. Example, the other day running short on beans, dropped in to the local supermarket as they had the large hoppers on the wall of their deli section full of various Coffex blends. Asked the girl behind the counter how quickly they turned over the beans and got that don't ask me I just work here look. She asked her work mate with the same result. Took a chance and grabbed a couple hundred grams just keep me going, got home and opened the bag and was about to tip into the grinder when I thought, that's funny, not much smell of coffee from the bag. Had a good smell and got nothing, not a hint of coffee aroma at all, they were dry and may as well have been dust. You can guess where they went back to. So remember FC's words and check what your buying.
