||Around the 13th century slaves were defined as those vines which, unlike the "maiores" or "maroche" raised high, were cultivated on low stumps along the rows and tied together. With this name, very different vines were indicated. This particular vine, "gentle slave of Tyrol", appears in Molon's work (1906) and according to Rigotti (1932) it is native to South Tyrol.
||Leaf: more than average, rounded, trilobata or almost whole, petiole breast often closed and with overlapping edges; Lower side nieces absent or just mentioned; Corner at the top of the obtuse medullary lobe; Corrugated lobes, little marked, a bit sharp; Wavy flap; Upper page dark green, dull, bollosa; Bottom light green page, with hairs along ribs; Protruding, greenish ribs. Thick teeth, a bit irregular, sharp.
Bunch: medium size (about 15 cm long), pyramidal, with a wing, spatula; Visible, thin, herbaceous peduncle; Medium, thin, green pedicels; Noticeable, reddish, verrucous green; Medium brush, red. Since the leaf of this vine is very similar to that of the "Big Schiava" (and "Tschaggele"), it is the cluster that is best placed to distinguish the three vines.
Acino: medium, subtropical, slightly irregular; Blue-violet peel, pruinal, tender, medium-thick; Persistent navel, infused; Juicy flesh, simple flavor, sweet.
