Room temperature is the best to preserve honey and its qualities. In a well closed jar that is placed where there is no direct exposure to the sun light who can preserve the honey for years. The honey does not roten. Even if the honey will turn into a crystalized solid material you can recover it to its initial texture. ou only need to know that for recovering you need to heat it in very low temperature. Ben marie is the most efficient way to do so. High temperatures should be avoided, it can burn the honey composits and lower the initial quality in terms of nutrition but flavour, as well.
