Not all eggs are made the same
At a first glance, eggs may all look identical. However, they can be distinguished in terms of calibre (S, M, L, XL), type of farming (on the ground, free-range, organic, traditional), and freshness (fresh or extra-fresh).
Let's find out more about these characteristics:
S - small: weight inferior to 53 g
M - medium: weight equal to or exceeding 53 g and below 63 g
L - large: weight equal to or exceeding 63 g and below 73 g
XL - extra-large: weight exceeding 73 g
These weight categories are established by the regulations regarding eggs (Reg CE 589 of 24/06/2008).
Type of farm

The bottom part of all eggs contains an air sac that determines its freshness. If the air chamber is more than 4 mm high, the eggs are extra fresh (and can be sold under this denomination until the ninth day after laying). If the air chamber is between 4 and 6 mm high, the eggs are fresh.
