I’ve thought about coffee, but it’s one of those things that no one agrees on. I like mine strong and black. Ninety % of the coffee I buy out is weak and I practically have to spit it out. Then you have to have all that crap people put in it. I wouldn’t feel right if I had to use anything less than half and half to lighten it with. That would be a pain on the cart (HD wise).
Hot Chocolate seems to be the better choice. Easier to make gourmet.
