Inia One


Maylen® or Iniagrape-One is a black seedless table grape. The skin colour is actually a uniform dark blue and the medium to large berries are ellipsoid in shape, reaching a diameter of 20-22 mm. The skin has slight resistance on biting, though has no bitterness, while the flesh is soft and bursts with juice. The sweetness levels are high and acid balance is good (19-21 brix and 0.9-1% acidity at harvest). The flavour is attractive, said to be Muscat-like and fresh.

The berries normally contain 2 to 3 rudimentary soft seed traces and very occasionally contain a fully developed seed.

Iniagrape-One is described as a mid-season, blue-black seedless grape.

Growers are attracted to Iniagrape-One as a mid-late season alternative to Autumn Royal, and due to its good keeping and shipping qualities; easy of growing, and ease of colouring. There is also no problem with of shatter during harvest or post-harvest.
