I do not know what she meant by best coffee maker, but I can tell you that it is not easy to find such an equipment. Why would I say that? Well, the situation is such that we all have differing taste profile. So, how the coffee maker brews one coffee might be acceptable to you, but it might not go well with me. Take for example, my use of keurig coffee maker. Many people say that it is a good coffee maker, but to me while it is a useful machine, I think I am not learning much from it, so I am still considering if I should be buying an espresso coffee maker. This is how I think, if you would to ask me for opinion.
