Segura Viudas is a renowned Spanish winery with a long history in the Penedès region of Catalonia, known for its Cava, a traditional sparkling wine. The brand's origins trace back centuries, with the estate's history dating to the 11th century, although the modern company was established in the mid-20th century. It is now part of the Freixenet Group, a major player in the sparkling wine industry.

The brand's identity is a blend of tradition and a commitment to modern quality standards. Segura Viudas focuses on crafting Cava using the traditional method, where the secondary fermentation that creates the bubbles occurs in the bottle, just as it does in Champagne. The wines are known for their complexity, balanced acidity, and fresh, fruity character, which comes from a blend of the traditional Cava grapes: Macabeo, Parellada, and Xarel·lo.

Segura Viudas is recognized for its flagship product, the Brut Reserva, which is a versatile and elegant sparkling wine. It also produces more exclusive expressions, such as the Reserva Heredad, which is presented in a distinctive metal-based bottle. The brand's commitment to sustainability is also a key part of its modern identity, with the company having received certifications for its environmentally responsible practices.
