I don't think we can have a god of coffee. A subcommittee for beverages (Baccus - a god of inebriation is a standard - being chairohdearitsfallenoverI'lljustsitonthefloorthenperson) and including representatives from the chocolates and associated sweetmeats subcommittee. You could co-opt a few nymphs and similar second rank immortals (except when you concrete over their springs)
Subcommittees were rife in the greek system, with responsibilities carefully defined by their superiors; muses, graces, furies, for aesthetics and other non-critical functions (how come only females leap to mind?)
Many of these might have been goddesses in their own limited regions, but, with the takeovers involved with spreading civilisations, accepted subordinate posts in the new deocracy - and even if the furies are a bit underemployed now, the muses are still recruiting for a wider spread of arts. (who's the girl who got "pornographic videos"? She's doing all right for herself, even if her immortality might not be assured, and the muse of epig fantasy? I pour a libation)
