Mutsu is an unusually versatile apple. Its large size and juicy acidity make it an excellent apple for the kitchen. Slices keep their shape when baked, but it can also be cooked for apple sauce, and slices can be dried too.

Mutsu's Golden Delicious parentage also lends it an excellent sweet flavor for eating fresh, particularly if you like sharper apples. In a good year from a good tree, Mutsu's crisp sharp-sweet flavor can be very good indeed.

All in all this is an apple with many talents, and one of that select band of apple varieties that is equally good for eating fresh or in the kitchen.

How to grow

Mutsu is a triploid variety, so not a good pollinator for other apple varieties.

Disease resistance is not the greatest, but like all triploid varieties it is a strong-growing tree that can tolerate a few problems without much effect. In practice is much easier to grow than you might guess from its characteristics.

Mutsu likes a warm climate but with cool fall nights.

Historical details

Mutsu was developed in Japan in the 1930s, and is a cross between Golden Delicious and Indo. It has become steadily popular in both North America (where it is often known as Mutsu) and parts of Europe (where it is known as either Crispin or Mutsu).
