US basketball champion Giannis Antetokounmpo has invested in Greek winery Boutari through his family-owned investment business, Ante.

Ante has acquired a 10% share in Hellenic Wineries, a holding company that owns Boutari Wineries.

As part of the deal, Ante CFO Kostas Tsigkourakos will be appointed to Hellenic Wineries’ board of directors.

Greece-born sporting brothers Giannis, Thanasis, Kostas and Alex Antetokounmpo launched Ante in June to “have their greatest positive impact on the world”.

Ante said the minority share in Hellenic Wineries was “driven by [the brothers’] deep interest for agriculture, their passion for exporting Greek products internationally and their desire to support the growth of the historical sector of wine”.

Hellenic Wineries bought Santorini-based Boutari Wineries last year and also owns Greek bottled-water brand Ioli.

The family-run winery produces over 40 wines and exports to 25 countries. As well as Santorini, it has wineries in Naoussa, Goumenissa, Mantinia, Attica and Crete.

Elias Georgiadis, CEO of Hellenic Wineries’ majority shareholder Sterner Stenhus, said: “By joining forces, we further enhance our strategic plan for the international recognition of Greek products, as well as the growth of wine tourism in our country.”

All four of the Antetokounmpo brothers play basketball professionally. Giannis and Thanasis play for the Milwaukee Bucks in Wisconsin while Kostas is with Greek Basket League team Panathinaikos. Alex, the youngest brother, plays for the Wisconsin Herd.

In June the brothers also invested in Canadian confectionery company Candy Funhouse to help expand the brand internationally. Ante said it has a “physical presence” in the US and Greece but has plans to expand. Each of the brothers sit on its board, while Giannis is also chairman.
