There is a widely-held view, that only the old heritage apples have real flavour, and that new mass-market varieties aimed at filling supermarket shelves are tasteless. There is perhaps some truth in this, but as consumers increasingly look for flavour in their shopping baskets, growers have begun to respond by developing varieties where flavour is more prominent than it used to be in the previous generation of supermarket apples.
Jazz provides the best evidence yet that modern apple development is pulling ahead of the traditional heirloom varieties. Jazz is a crisp hard apple with an excellent strong sweet-sharp flavor, and a pronounced fruity pear-drop note. The flavor undoubtedly puts it in the first rank of apples, and it is hard to think of a traditional variety that can compete with it.
The butter-yellow flesh is juicy, crisp and dense. Indeed perhaps the one drawback of Jazz is that it is a very solid apple, and may be a bit difficult to bite into if you do not have strong teeth - the solution is to cut it into slices first.
We have been advised by Steve T of New Zealand that the red colour is key to the unique Jazz flavour - poorly-coloured apples will taste like Braeburns. From our own tests we would tend to agree with this.
Jazz is actually a trademark, and the true cultivar name is Scifresh.
It is worth comparing Jazz with its sibling - Kanzi - see our review of Kanzi apple, including comparative photo.
Jazz tends to become available towards the end of the season - so in northern Europe and North America locally grown fruit comes into shops in November/December whilst southern hemisphere apples will be available in May. A more deeply-colored sport called Southfield has been found, which ripens a bit earlier.
The appearance and keeping qualities are very good, and in our opinion it has by far the best flavour of all the mainstream apple varieties - indeed it is the only supermarket apple variety which makes it into our Top 10 Apple Varieties.
