I came across these two new apples in my local grocery store. Opal and Ambrosia.
Opal has the appearance of light brown-green color skin. It's far from the "red" and "green" like variety. It was found in 1990's around British Columbia Canada . It was stumbled upon in a family farm. It's believed naturally cross-breed between Starking Delicious and 'Golden Delicious.
Ambrosia has the appearance of red with light green hue skin. It looks like any recent varieties of bio-engineered apple. It was only recently Developed by the Institute of Experimental Botany in Prague and FruitSelect in 1999. It's growing in Washington.
