Sumarroca is a family estate in the Penedes, based at Subirats between Sant Sadurni d'Anoia and Monistrol d'Anoia in the heart of D.O. Cava. The family, with roots growing vines in Pallars Jussa, built the estate from the 1980s and today farms around 220 hectares of certified-organic vineyard on poor limestone soils, cooled by breezes off the Garraf massif. For the 2021 Gran Reserva, the traditional Cava trio of Parellada, Xarel-lo and Macabeo is grown alongside Chardonnay, hand-tended for clean, ripe fruit with the firm acidity that supports long bottle ageing.

Each variety is picked and vinified separately, with a gentle settling and a cool primary fermentation around 14C. The base wines are blended and bottled for a second fermentation by the traditional method, then aged on lees for a minimum of around thirty-six months to earn Gran Reserva status, developing toast, nutty and patisserie notes. After riddling and disgorgement it is finished Brut Nature, with no dosage added, to show the wine's natural drive and precision. Blend around 42% Parellada, 29% Xarel-lo, 22% Chardonnay, 7% Macabeo; exact 2021 proportions NEEDS VERIFICATION.
