FIFO - First IN, First OUT is a rule of inventory management, at home and in the warehouse.I think freezers are a great way to buy meat on sale and save some money. But how long does meat last in a freezer before it gets freezer burn? I heard somewhere that you should rotate your freezer meat so that it is used up within 6 months. Does it depend on the type of freezer you have - that is, frost free versus regular freezer? Don't really know. But we have taken out some meat that had freezer burn and that was not good.
BTW, I think it's a good idea to put a label on freezer products along with the date. So far, I have been able to convince myself but Dear Wife is taking a little longer to get on board with that idea.
Freezer Burn is (mostly) Oxygen. Use a vaccuum sealer, and freezer burn is (largely) a thing of the past.
Chest freezers let less cold air escape when you open them, and draw in less moisture. They tend to produce less freezer burn. They are also hella inconvenient to get stuff off the bottom, where it goes to be forgotten.
Uprights are convenient, but much less efficient. Open the door, all the cold heavy air flows out the bottom, while drawing warm, usually much more moist air from above the freezer. More burn, and slower freezing times, leading to greater textural differences post defrost. There are, of course "tricks" to minimize this.
Life is a series of trade offs.
