How humid is the wine room? Good cellars need a bit of humidity, green coffee doesn't.
I have never had any issues storing coffee, in various methods - fabric bags, tuppaware style containers that hold about 3KG each, large foil type coffee bags folded down & sealed with a clothes peg.
All of these methods, the coffee is then placed in a large steel cabinet that I use for storing it - dry, dark, cool.
They say green beans can be kept for up to 3 years, so I would suggest a few months in ziplock bags won't hurt them so long as they are dry. If they're not dry I reckon you will know as mould will likely grow. I think fabric bags are usually used so they don't get condensation, a bit of breathing not a bad thing.
On another matter - "a wine room" - full blown cellar? Photos? Wine is another passion of mine.
