Kaiku Km.0 Baserriko esnea whole milk

Kaiku Km.0 Baserriko esnea is a premium whole milk product originating from the Basque Country in Spain. The brand, Kaiku, was established in 2004, though its roots trace back to the mid-20th century (1950s) through various dairy cooperatives in Gipuzkoa, Biscay, and Navarre. The 'Km.0' branding signifies a commitment to local production, where the milk is sourced directly from over 1,000 local family farms (baserris) and processed within hours to ensure maximum freshness.

While the brand has deep local roots and is headquartered in San Sebastián, it is part of a larger international corporate structure. Since the mid-2010s, the Swiss dairy giant Emmi Group has been the majority shareholder of Kaiku Corporación Alimentaria. Despite this international ownership, the production remains strictly local in northern Spain, supported by strategic partnerships with local cooperatives and regional governmental bodies like the Basque Government, which maintains a minority stake to ensure the preservation of local agricultural heritage.
