Once you have let oxygen into the container, it will start to turn the
oils in the nuts rancid. Keeping it in the fridge slows the process down.

If you are using it up in a month, it probably doesn't matter how you
store it. Keeping it out of direct light would be my goal.

It also lets in wild yeasts, molds and other nasties. Coffee has not
been treated with sulfates to retard molds and such. The fruit in your
trail mix probably has.

I keep a couple of pounds of coffee in my freezer. This is sent to me
from Hawaii. I don't use it every day. Usually I would only buy these
things, (food items stored at room temp.) in quantities which would last
about a week, but the shipping from Hawaii is such that I feel obligated
to purchase 5 pounds at a time. So, my Kona coffee lives in the
freezer, and I dip into it once a week, or so.
