100% Terrantez, a now-rare white Portuguese wine grape variety that was once widely used to make Madeira. Fewer than 14 acres are planted in the world! The vines are over 100 years old and are grown on small volcanic black rocks (biscoitos) and surrounded by stone walls called currais. The rocks heat up in the sun, helping the grapes ripen, while the walls protect the vineyards from the elements. All free run juice. Fermented and aged in a single, large old American oak barrel. 12% alcohol. Only 1715 bottles were made. Complex and extremely concetrated, with aromas and flavors of lemony citrus, apricot, nectarine, honeysuckle, salt and smokey volcanic mineral notes. Medium bodied, with extremely high crunchy acidity and a saline finish. Age for 15+ years. Legendary wine!
