Whether it’s a big storm coming or a public health concern, experts say that they often hear about people going to the grocery store to stock up on essentials like milk and bread.

But what can you do if you want to stock up on milk but worry about it expiring before you can safely get back to a grocery store? The answer, like so many foods, is simple. You can freeze your milk.

You can stock up on your favorite brand of milk and freeze it, by following these steps provided by America’s Dairy Farmers:

1. Consider the space you have in your freezer. If you don’t have room for a number of large milk gallons, think about stocking up on half gallons and quarts of fresh milk.
2. Drink some first. When milk freezes, it expands. So, drink enough from each container to leave a little bit of room for the milk to expand safely when it freezes. Leave one to two inches of empty space in each container.
3.Thaw your frozen milk in a refrigerator, not at room temperature.
4.After your milk is thawed, give it a good shake before drinking.
