Mold will grow on anything, it depends on the way you store it. You can get mold to grow rather quicly on anything given the right conditions. Store your unused coffee in a cool dry place, or freeze it, and I doubt mold will ever grow. use the grinds before the falvor fades from the grinds, making them usefleess to any real coffee lover.

Mold requires moisture, mold spores. mold food, and the correct temperature to grow. Take any of these away and you will not be able to grow mold. So keep the coffee grinds in a cool dry place and never worry about mold.
