Bertolli is known for its olive oil, in which it was the global market leader, but has now widened its range to include pastasauces and ready meals. In 2008, Unilever sold the olive oil business to Grupo SOS, Spain’s second-largest food group, for £500m as part of its disposal of non-core businesses. The transaction included the sale of the Italian Maya, Dante, and San Giorgio olive oil and seed oil businesses, as well as the factory at Inveruno, Province of Milan, Lombardy. Unilever retained the Bertolli brand for all other categories including margarine, pasta sauces, and frozen meals. The frozen foods business under the Bertolli brand name was sold by Unilever to ConAgra Foods in August 2012.
Some controversy emerged in 2010 when Bertolli Extra Virgin Olive Oil was identified as one of the olive oils mislabeled as extra virgin in a study by University of California, Davis.
