Traditional method or “champenoise” method. Once the cuvée has been obtained from a white perfumed variety such as Macabeo with the combination of a full bodied Chardonnay, it is aged in the bottle for a mini-mum of 12 months. During this time the bottles are kept horizontal, called ‘ageing in stacks’, at a constant temperature of 15ºC, in order to carry out a second fermentation gathering the lees along the length of the bottle.
