It is one of many “club apples”, only licenced commercial growers can grow them.
So far, these are club apples : Ambrosia, Autumn Glory, Cosmic Crisp, Envy, EverCrisp, Jazz, Kanzi, KIKU, Lady Alice, Opal, Pacific Rose, Pinata, RubyFrost, SnapDragon, Sonya and SweetTango.
Among these, only Opal is a yellow apple. The rest have varying degrees of redness in them.
I’ve eaten 6-7 of them. To me, a couple of qualities they share are crunchiness and intense sweetness. Like it or not, buyers in general like sweet, crunchy apples. Look no further than the popularity of non-club Honey Crisp, an inspiration of these club apples.
Growers like us cannot grow these club apples.
