The skin is very thick and waxy, it is almost like one needs to scrub the grease off of it. Wait, let me go get one and describe it in real time.
Greasy thick skin that has the slightest raw chlorophyll-like taste, the skin needs extra chewing. Yellow flesh with medium juice content, medium sweetness, but with no bite the sweet
apple flavor lingers a long time. Taking a huge bite, the flesh is imbued with a bubbly popping much like a carbonated drink.
I am happy I took a chance on this Zone 6 tree. And the apples do have some black skin as advertised!
