Sos Cuetara, a Spanish bottler of olive oil, agreed to buy oil brands, including the market leaders Bertolli and Dante, from Unilever for 630 million euros ($1 billion). Sos Cuetara, based in Madrid, gains labels that have about one-third of their sales in the Americas as it tries to reduce dependence on Europe. Bertolli, founded in Tuscany in 1865, is the world’s biggest brand of olive oil, followed by Dante and Sos Cuetara’s Sasso, according to Unilever, which has headquarters in London and Rotterdam. The acquired assets generated 380 million euros in sales last year, compared with Sos Cuetara’s 1.4 billion euros of annual revenue.
