Description
A Vinho Verde selection with very high β-glucosidase activity, so it lifts lime and grapefruit aromas and converts thiols out of an otherwise plain base. Fructophilic, undemanding on nitrogen and content in a heavily clarified juice — which is why it survives the thin nutrient of a cider or a sugar wash.
