Incense is a pretty popular product nowadays.

A question I often see asked is whether or not incense expires.

The answer is that incense does not ‘expire’ in the sense that the product cannot turn rancid or harm the person burning it.

As for the incense aging, depending on the type of incense, it may get better or worse.

Some of the more expensive agarwood incense sticks can become smoother and lose some of their acridity after aging for a couple years.

However, some of the cheaper incense sticks which rely primarily on oils or perfumes can lose some of their scent after a few years.

This is because the oils and perfumes are more prone to degradation than crushed plant material.

If stored properly, most incense can remain fresh and fragrant for years.
