You might try making a list of coffee-related processing, technical words, or other manufacturing-related terms that relate to some aspect of your concept (product, menu, space design, customer service, etc). See what works on a couple of levels, but won't confuse people about what your business is. My guess is that something good will jump out at you. Good luck!
Pick something like an element, or a color, or a building material? I find names are always more satisfying pulled from one's own mind.
