To make this cava, the best white wines of the Chardonnay, Parellada, Macabeo and Xarel-lo varieties are selected. After adding the sugar and selected yeasts, the second fermentation is carried out in the bottle (traditional method) in our Jaume Serra cellars, at a temperature never higher than 16º C in order to achieve a small and persistent bubble. This cava remains in our Jaume Serra cellars in strict darkness and silence for a minimum of 24 months.
