Farmers at the Parc Agrari del Delta del Llobregat are reporting a landmark season this February 2026, with crops in Viladecans showing exceptional size and a unique saline flavor profile.

Traditionally associated with the Alt Camp region, the cultivation of calçots (sweet spring onions) has flourished in the Baix Llobregat. The delta's soil provides a delicate salty undertone that contrasts with the onion's natural sweetness, a characteristic also found in the famous Prat Artichoke.
This local produce is the star at Mamut Beach Club, a venue owned by Grupo Lancaster located near la Murtra lagoon. The restaurant offers a farm-to-table experience where the onions are grilled just meters from where they were grown, served in a seaside setting in Viladecans.

"This year's harvest could be anthological because the onions are sprouting as thick as they are tender."
