Trena is made with Tardana grape. Its name comes from the place known in the region as “El Tresnal”, where it was usual to pile harvest bundles in the shape of a triangular prism after reaping to lose moisture before being taken to the threshing floor. Calcareous clay soil with a sandy clay texture. The soil is poor, shallow with the peculiarity of having horizontal layers of limestone, red clayey loam and fine sandstone formed in the Tertiary Period. Tardana variety is a native grapevine with thick skin and a long cycle, very well acclimatised to the ecosystem of the interior of the province of Valencia, more than 700 metres above sea level. The plot’s land is seated on a calcareous clay base. The 2021 harvest was carried out on the 6th October, by hand and in 15-kilo boxes. Alcoholic fermentation was driven spontaneously by wild yeasts in concrete tanks and high-capacity oak foudres, where it rested on fine lees until bottling. A gentle filtration was done.
