This is a climate on the edge of what is possible: at 1,100 metres above sea level, the grapes experience a large diurnal range that encourages even ripening and helps to retain natural acidity. Rosalia’s vineyards are certified organic, she uses only natural fertilisers, promoting biodiversity by welcoming chickens, sheep and pigs from local farms to roam the vineyards freely. Grapes are hand harvested and vinified as naturally as possible with native yeasts and little other intervention. The wines are then aged in clay amphora and some in French oak to give texture and complexity.
