Ostatu Blanco Gran Reserva 2019

Description

Vintage exclusivity
Viura and Malvasía come together in this white wine born from the highest areas of our oldest vineyards, where altitude and limestone soils impart character and freshness. It is only crafted in exceptional vintages, when these varieties reach their fullest expression.

This is the second vintage of a wine that showcases the aging potential of white wines from Rioja Alavesa. After more than a year of aging in French oak barrels, it offers aromatic complexity and a rich, enveloping texture that make it truly unforgettable.

Winemaking

Pre-selection in the vineyard ensures that only the best grapes reach the winery.

A gentle destemming process is carried out to avoid damaging the berries, followed by light crushing. Cold pre-fermentation maceration lasts for 5 hours.

The must, along with its lees, ferments in stainless steel tanks for 23 days at a controlled temperature of 15–16°C. Stabilization is achieved through natural cold.

Filtration is applied only for tartaric stabilization. No malolactic fermentation was carried out, and the wine was aged in second-use French oak barrels for just over a year.
