Another tip - frost-free freezers are best for long-term storage. If you want to store items for longer than 6-8 weeks, a "frosty" freezer works best.
This is because of the way frost-free freezers work. They stay frost-free because the freezer sucks all the moisture out of the inside of the freezer. That way the moisture doesn't build up and freeze on the inside. However, this can cause freezer burn, even in foods that are sealed. The freezers that get frost buildup are a pain because you have to defrost them every year or so, but they're much better for longer-term storage.
