This Japanese apple is a descendant of the Golden Delicious. It is large, spicy, crisp & juicy. Excellent all-purpose apple.
Various sources say this is the Crispin apple by another name.
Mutsu is bigger and greener than Golden Delicious, whatever its relation.
This is a large fruit, almost cylindrical, with definite ribs and a light green-yellow skin.
The color varies from green-yellow to yellow-green and has darker green spots perhaps a tenth of an inch across, some with tiny white centers and some with tiny brown ones.
The flesh is firm, creamy light-yellow-green, juicy, and crunchy. The flavor is mild and light, with a sweet-tart mix that is balanced but not very vivid. There are faint notes of ginger and spice, and perhaps vanilla. There is a some pleasing astringency after the finish.
Mutsu is a fun apple to eat because of its heft, juice, and crunch. The flavor is not simple, but some might find it a little washed out.
Where some apples taste like cider, Mutsu's refreshing lightness is more like a cool glass of water with an apple tang.
