In Focus: The Alfonso Olive
The Alfonso is South America’s answer to the big Mediterranean table olive — a large, deep-purple fruit, soft and meaty, with a distinctive tart, wine-touched flavour. It comes from the Tacna region on the Pacific coast, an old olive district that now sits under Peruvian rule, and it is among the best-known eating olives of the Americas.
A New World table olive
The Alfonso belongs to the olive culture that the Spanish carried to South America centuries ago, and it is grown in the dry coastal valleys around Tacna — long associated with Chile, though the growing district has been Peruvian for generations. It is purely a table olive, prized for its size, its tender flesh and its bold colour. The deep purple-brown hue comes partly from ripeness and partly from the curing: Alfonso olives are traditionally brined with red wine and vinegar, which both colours them and gives the variety its signature tang.
Flavour and the table
The taste is forthright — meaty and soft, with a pronounced tart, slightly bitter, wine-and-vinegar character that sets it apart from milder Mediterranean olives. It is a robust, full-flavoured fruit rather than a delicate one, and it stands up well to strong company. In Peru it is woven into the local kitchen, most famously in arroz al olivar, an olive rice, and in the creamy olive sauces of the coast. Served simply, it makes a striking, generous table olive for a board, where its size and colour earn it attention.
That wine-purple colour and tang come from the cure, so check the label — a real Alfonso lists wine and vinegar in its brine. The flavour is assertive and a little sour, so it is not the olive for someone who wants mild; pair it with rich, savoury food rather than delicate dishes. Buy them firm and meaty, and serve at room temperature to bring out that distinctive tart character.
