One of Stan's favorite apples, the fruit is tart during the first weeks of harvest but the texture is already crisp and juicy. It gains in flavor and juice in the later harvest.
The Mutsu can be a very big apple, not always perfectly round but dense and heavy. It's a yellow-green color with a warm blush. During the last weeks of its season it is golden with a pink blush.
The Mutsu is hard to grow organically because it's very susceptible to apple scab and fire blight. But the Sebastopol climate is perfect: in warmer, dryer climates it would stay green and have less flavor.
