The coastlines. The bays. The fishing towns.

Galicia and northern Portugal are the heart of it, canneries that have been at this for over a century. Morocco's Atlantic coast packs sardines at a scale nowhere else matches, Norway owns the cold-water catch, and Japan preserves fish on its own entirely separate logic. 104 regions across 39 countries, each with its own page: what the place means to the tin, and the brands and producers that come from there.
