It is not advised to keep coffee in the freezer because it is porous and can absorb other flavors from other foods in the freezer.
A freezer!
You should only have your freezer turned down to level 5 out of 10 levels.
Absolutely NOT. Freezing coffee breaks down the oils naturally in the beans. Coffee is very porous and will absorb moisture, and other flavors such as "freezer burn." Your coffee should never be stored in the freezer or the fridge. Keeping it away from air is the key. In a well sealed container, in a dark cabinet at room temperature, your coffee will stay it's freshest!!
Store tequila in the freezer to keep it chilled and ready for serving.

Good ways to store coffee long term is to keep the coffee in an air tight container away from heat. You can also store coffee in vacuum sealed bags in the freezer.
0 degrees is ideal.
A domestic freezer should be set to these temperatures. 0o Fahrenheit. -18o Centigrade.

The answer of this partly depends on where you live. If you live in a tropical climate, it's best to keep your beans in the freezer, but in other locales, you can keep them on the bench. Importantly, don't keep them in the fridge. Also, the most important part of storage is the container. Most coffee roasters sell their beans in foil bags which have a one-way valve. This keeps the light out (and stops damage to the roasted beans) and allows gases to escape while not letting oxygen in. If you store beans incorrectly (unsealed, in the fridge) they will quickly go stale. If you store coffee ground and in the wrong container, it can take on the flavours of the food around it. In short: store coffee unground, in a valved bag, in the freezer or on your bench. source: Coffee tips: http://www.roastandpost.com.au/pages.php?pageid=19
They must be keep at room temperature, it's a bad idea to put the into a freezer.
Anything put in the freezer should last a long time, but it probably should not be frozen or used longer than a year.
