How to Test Fresh Eggs in Water

egg age

Since eggs come encased in a shell, it’s not always easy to tell if they are fresh. Whether you buy your eggs at the grocery store or from your local farmer’s market, you may wish to establish the age of your eggs before cracking them open. Floating an egg in water is an easy way to test its freshness. How or if the egg floats will determine its age; as an egg gets older an air sac develops inside the shell and increases in size. The larger the air sac, the more the egg floats.


1. Fill a small pan or bowl with room temperature water. If you are testing eggs that have been chilled in the refrigerator, use cold water that is not as cold as the chilled temperature of the eggs.

2. Gently place the eggs, one at a time, into the water. Make note of the behavior of the egg in the water. If the egg sinks to the bottom of the water and lies on its side, it is fresh. If the egg’s wide end floats a little, and its narrow end stays at the bottom of the pan, the egg can still be consumed. It is about one week old at this point. If the wide end floats up completely but the narrow end still touches the bottom, the egg is approximately two to three weeks old. An egg that floats completely, on the surface of the water, is old and should not be consumed.

3. Mark the date of your test and your results on the outside of your egg carton. Knowing the date that the eggs were fresh may save you the trouble of having to test the eggs a second time.

Hope you have a nice day!
