We've been round this before, perhaps that's why nobody has mentioned it
this time. 304 is OK for fermentation. Wineries use it all the time (as
do many cideries in the US at least). Pitting can occur where the surface
of the cider contacts the inside of the tank, if the cider is in contact
for a -long- time. If you intend aging in SS, then it's worth considering
316.
A much greater risk of metallic contamination for cider, if using brewing
equipment, is the presence of brass, copper, or plated fittings, valves,
etc. These are definitely not for use with cider as they can taint it in
short order.
