Original Wagner Steinofen Pizza Diavolo

Original Wagner Steinofen Pizza is a prominent frozen pizza brand with deep roots in German culinary history. Founded by Ernst Wagner in 1968 in Nonnweiler, Saarland, the company revolutionized the frozen food market by introducing the first stone-oven pizza produced on a large scale. The brand is celebrated for its traditional baking methods, utilizing a real stone oven to achieve its signature crispy crust.

Today, the brand is a major player in the European frozen food sector. While it was once an independent family business, it underwent a significant ownership change when Nestlé acquired a majority stake in 2005, eventually taking full ownership. However, in recent years, the business became part of a strategic partnership. As of 2026, the brand is under the ultimate ownership of Nestlé, but managed through the European Pizza Group, a joint venture between Nestlé and the private equity firm PAI Partners. Manufacturing remains primarily concentrated in its traditional home of Nonnweiler, Germany.
