Ivory (Sheegene 21)


Ivory is a medium-sized, green seedless grape with round berries. The skin offers some slight cracking resistance on biting, and can be felt slightly while chewing, though results in only minor astringency.  The berry texture is very crisp and it has good levels of sweetness, achieving 18-20oBrix, with fairly low acids.  The flavour is relatively mild, developing noticeably in the best examples.  Ivory is often regarded as similar to Thompson Seedless, though not in shape.

The colour of the grape on sale can vary from a clear green to a straw yellow. The best examples of Ivory are firm with a cracking bite of thin skin, a crisp texture and high levels of sweetness. The yellower fruit tend to be the sweetest, but can have slightly lower crispness, depending on growing conditions and harvest management.

Ivory is an early-mid season grape.  It matures approximately four weeks earlier than Thompson Seedless. It is regarded as an alternative to Sugraone.

Good Fruit Guide Rating: ****
