I do not know about this
Seriously, if you asked me, I really have not heard of it. What I think is this single cup coffee maker secret must belongs to a group of really close industry watcher, otherwise how it is possible that I have not even hear about it before. I am talking to a group of coffee lovers when they mentioned that there is this thing going around that would allow you to use any coffee grounds you like on your favorite Single cup coffee maker. I do not really believe them but their proof is pretty solid and I think this thing might be real after all…
