Pine nuts are the edible seeds of several species of pine tree (genus Pinus), harvested from the cones of specific varieties. The most commercially important species include the stone pine (Pinus pinea) from the Mediterranean, Korean pine (Pinus koraiensis) from East Asia, and several piñon pine species from the Americas.
Pine nuts have a soft, creamy texture and a mild, slightly sweet and resinous flavour. They are best known as a key ingredient in Italian pesto and are also used in salads, baked goods, and Middle Eastern and East Asian cuisines. They’re typically sold shelled and are often lightly toasted before use to bring out their flavour.
Pine nuts are among the most expensive nuts on the market, reflecting the difficulty and slow pace of harvesting them. A small number of consumers experience “pine mouth” — a temporary metallic or bitter taste that can last days after eating certain pine nut species, the cause of which is not fully understood.
How it's produced
Pine nut production is a slow and labour-intensive process. Pine trees take years to mature and produce cones — stone pines may take 15 to 25 years before producing meaningful yields. The cones themselves take two to three years to develop on the tree before the seeds are ready for harvest.
Cones are collected from trees (often by hand or with the aid of mechanical shakers), then dried until they open to release the seeds. Each seed is encased in a hard shell that must be cracked to access the small edible kernel inside. Much of the global supply comes from wild or semi-wild trees in China, Russia, and Mediterranean countries, with limited plantation-scale cultivation. This reliance on wild harvest, combined with the slow growth and small yield per cone, keeps prices high.
