This is so sweet! I think it is simple but it says all it needs to say. My one suggestion is that you might want to take out the periods after each stanza. They break the poem up and make it feel like there is an ending and a pause between each stanza. That could be a good thing if that's what you were going for, though.
well I personally love the divine brew that you mortals so erroneously refer to as "coffee". I like this poem... it really is simple sweet and lovely... and your description reminds me of a series of dreams that had been having which culminated with some unknown and unseen woman kissing me on the side of my jaw... really was sweet in the dream but when I awoke It only made me ache with loneliness.
