Arándanos El Cierrón is a family business in Fuentes, in the municipality of Villaviciosa (Asturias), that grows blueberries and other forest fruits. It is named after the El Cierrón estate, where the family planted its first blueberries in 1989, and it later added a nursery for berry plants, registered as Vivero Les Vegues. The fruit is now grown organically using precision farming techniques.

The farm produces organic blueberries and organic mini kiwis, known locally as kiwiños, while the nursery propagates blueberry, raspberry, currant, aronia, mini kiwi and other berry plants, including dwarf varieties for urban gardens and the BrazelBerry range. The nursery can be visited by appointment, and the business also gives advice on growing berries.
