As all in its group, post-mature is mealy and bland, and before maturation is too acid, but freshly picked in the right month is a refreshing mix of acid/sweet in the right amounts. Really fine apple when in season.

But is really annoying to culture. Many of the best tasting apples are prone to fungus diseases that destroy its market value. GD is a sucker for skin diseases and the newer cultivars are better performers, so is in decline.

Apples in the kitchen burn its sugars to keep the fruit 'breathing' and the metabolism of the seeds working. The more time you have it, the more insipid.
