[3] Already before these studies, ampelographers believed the grapes to be related due to the similarities of clusters, berries and leaf characteristics.

In the Classico zone of Soave, where yields are most often kept in check, the grape can produce a delicate wine with lemon, almond and spicy notes.

In the fertile flatlands outside the Soave Classico zone, the grape can produce excessively high yields that lead to very thin and neutral flavored wines.

The acid levels in Garganega lends itself well to the production of sweet recioto wines that have the potential to improve with bottle age for a decade or more.

[4] An Italian study published in 2008 using DNA typing showed a close genetic relationship between Garganega on the one hand and several other Italian grape varieties on the other hand: Albana, Catarratto, Empibotte, Greco Bianco del Pollino, Malvasia di Candia a Sapore Semplice, Marzemina bianca, Montonico bianco and Trebbiano Toscano (also known as Ugni blanc).
