Topaz is a modern apple variety bred by the Institute of Experimental Botany in the Czech Republic from a cross between Rubin and Vanda. It is one of a series of varieties bred by the Institute for resistance to scab.
Topaz is a small to medium sized, slightly ribbed flat round apple. It has an attractive appearance with bright red stripes and flush over a yellow background. The flesh is yellow, crisp and juicy with a tangy sharp flavour. It ripens late and keeps very well. The tree has a compact habit and spurs freely. It is a heavy cropper. It has very good scab resistance and some resistance to powdery mildew.
Topaz is one of the best garden variety particularly for those who prefer sharper flavoured apples. Its compact habit makes it particularly good for small gardens.
