Aging and Hanging: Game Flavour Development

The hanging of game — allowing ungutted or gutted birds and mammals to age at cool temperatures for days or weeks before cooking — is one of the oldest culinary traditions in Northern European, British, and Scandinavian cooking. The technique produces the "high" flavour associated with properly aged game: the enzymatic breakdown of proteins that produces amino acids and glutamates (flavour), the controlled bacterial activity that develops complexity, and the moisture loss that concentrates the remaining flavour.

Game birds and mammals aged at cool temperatures (4–8°C) for specific periods before cooking. The aging transforms both the texture (enzymes break down tough connective tissue, tenderising) and the flavour (enzymatic and bacterial activity produces complex amino acids and aromatic compounds not present in fresh game).

Properly aged game tastes of its habitat — the complex, earthy, slightly funky character that distinguishes properly hung pheasant from a farmed bird cooked fresh. The aging is what makes game worth eating beyond its novelty. Without aging, most game birds taste merely of lean, slightly dark poultry.
