The age of an animal at slaughter profoundly influences the character of its meat, affecting everything from color and texture to flavor intensity. To understand why, let's explore how animal tissue changes as it matures, using some familiar examples that illustrate these differences clearly.

Consider the difference between veal and beef. Both come from cattle, but veal comes from young calves while beef comes from mature cattle. Young meat is generally lighter in color, more tender, and milder in flavor. As animals mature, their meat becomes darker, firmer, and develops a more intense flavor profile.

These changes occur for several interconnected reasons. As animals age, their muscles develop and strengthen through use. In young animals, muscle fibers are thinner and more delicate, similar to how a young sapling is more flexible than an old tree. As the animal matures, these fibers become thicker and more robust, contributing to firmer meat texture.

The color of meat also deepens with age due to increased myoglobin, the protein responsible for meat's red color. Young animals have less myoglobin in their muscles, which is why veal is notably paler than beef, and young chicken meat is lighter than that of a mature hen. This increase in myoglobin occurs because older animals have had more time to develop the cellular machinery needed to power their muscles.

Connective tissue also changes significantly with age. In young animals, connective tissue is more elastic and contains less cross-linked collagen. As animals mature, their connective tissue becomes more abundant and develops stronger cross-links, making it tougher and requiring longer cooking times to break down.

The fat content and distribution in meat also changes with age. Younger animals typically have less intramuscular fat (marbling), while mature animals develop more extensive fat deposits throughout their muscles. This contributes to the more complex and intense flavor profile of meat from older animals.

Many traditional cuisines recognize these differences and have developed specific dishes to highlight the qualities of meat from animals of different ages. In Spanish cuisine, suckling pig (cochinillo) showcases the delicate texture and mild flavor of very young meat. In contrast, many Indian and Middle Eastern dishes utilize mature goat or mutton, embracing its intense flavor through slow cooking with aromatic spices. In American barbecue, younger pork is typically used for pulled pork, while older, tougher beef is transformed through long smoking for brisket.

Understanding these age-related changes helps us select the right meat for our cooking projects. If you're looking for mild flavor and tender texture that works with quick cooking, younger meat is often the better choice. If you want robust flavor and meat that stands up to long cooking with bold seasonings, mature meat might be preferable. This knowledge also helps explain why recipes specify particular types of meat - when a recipe calls for "stewing hen" rather than "young chicken," it's accounting for these fundamental differences in meat properties.
