Yeah that's the one I was referencing. Ceres is also the goddess of agriculture and grains, so I figured he was asking for beer (Ceres) and wine (Bacchus).
Although your interpretation of Ceres would make this a much more interesting thing to write home to dad about.
"For you must know that without Ceres and Bacchus Apollo grows cold."
Ceres is the goddess of fertility. Bacchus the god of booze.
