47% Viura, 35% Chardonnay y 18% Tempranillo blanco.
All the grapes are supplied by an exclusive group of growers from different towns in Rioja Alta with whom the winery has long-term agreements. The Alta subregion benefits from a climate with a marked Atlantic influence, ideal for the production of high-quality sparkling wines, as the fruit displays low pH and is perfect for aging. The vines are, on average 10-25 years old. The winery jointly manages them to ensure the utmost fruit quality, with continuous monitoring during the growing cycle.
Vintage of excellent growing and sanitary conditions in vineyard. White wines were very expressive and well structured. All the grapes are harvested separately by hand in the first and the second week in September.
All the grapes are assessed on a sorting table. The extraction of the must is gentle and delicate, with low yields. The must from each variety undergo the initial alcoholic fermentation separately, in small stainless-steel tanks at controlled temperatures. After fermentation, the single-varietal base wines are combined and the resulting blend is transferred to a similar tank, until January, when the tirage takes place and, with it, the second fermentation in the bottle.
The wine is kept sur latte in the winery´s underground cellars for at least 19 months aiming to merge the brightness and freshness of this terroir on top of adding complexity and elegance. Afterward, disgorging was carried out in september to continue ageing for at least another 4 months, until its release to the market.
These ageing periods would allow it to be labelled as Brut Reserve in other wine regions.
