There are so many of us who are either watching our weight, are older or who otherwise prefer low fat milk with our coffee.
As the best expresso and latte is made with fat free milk, I would be a buyer of your SKINNY milk (only). That is, not packaged with expresso. You now do this with the cream based milk. I would think it is only a matter of packaging. I bet you would sell a significant amount. Why not do a marketing study? Thanks.
