Rubinette is a modern apple variety developed in Switzerland between 1964 and 1982, and also known and trademarked as Rafzubin. Switzerland is perhaps not the first country that comes to mind when considering the development of new apple varieties, but don't let the lack of track record put you off, Rubinette is an exceptional apple and anyone who appreciates apple flavours should certainly try to get hold of some Rubinette apples - you won't be disappointed.
Rubinette is moderately good-looking, with characteristic orange and dull red streaks over a light green/yellow background. The apples are generally small to medium-sized. There is also a red sport known as Red Rubinette or Rubinette Rosso. The redder colouring is not necessarily an improvement although subjectively the apples seem slightly larger. Overall the appearance is attractive but in a rather subdued sort of way.
The parentage is thought to be Golden Delicious and Cox's Orange Pippin - a very popular combination with other growers over the years. The obvious comparison is with Freyberg, which has the same parents - Freyberg has a very different flavour and colour though, far closer to Golden Delicious, but the shape is similar to Rubinette.
Rubinette is unfortunately not easy to grow. Like Cox it is quite prone to the apple disease scab. Mild attacks do not affect the flavour but make the apples rather unsightly and this limits its commercial appeal. Apples from young trees also tend to be very small, although the size improves as the tree gets older - and as noted below, ruthless thinning in late spring will increase the size of the remaining fruits. These horticultural difficulties mean that Rubinette is not widely grown - it is grown commercially on a small scale in Europe and a few North American growers have also taken it up. As a result, it is difficult (but not impossible) to find Rubinette apples on sale. Growing your own tree may be the best option, albeit a frustrating experience in some years. Although developed (like most modern varieties) to work with the popular commercial dwarf M9 rootstock, for garden use, we recommend you try the more vigorous MM106 rootstock. This rootstock suits the weak growth habit better, and also gives you more training opportunities - including espalier forms, which can be easier to monitor in a garden environment for the inevitable scab, mildew, and aphid attacks, as well as giving potentially better fruit quality. We have also heard some unsubstantiated reports that fruit size is better on MM106 for this variety (normally M9 gives better fruit size than MM106).
We have received some horticultural information from Promo-Fruit, the originators of Rubinette (see www.promo-fruit.ch). They recommend that it is important to ensure that the fruit is heavily thinned. Allow no more than 1 fruit per set of blossoms, and make sure you remove the central fruit (which tends to be the biggest, known as the 'king' fruit). From our own experience we think this is good advice - be ruthless with the thinning, and you will be rewarded with at least a few apples of good medium size.
So, a moderately attractive small apple that is difficult to grow ... why do we think it is so good ? Well, very simply, this apple has a superb flavour. Regardless of the contribution from Golden Delicious, there is no doubt that Rubinette is a Cox-style apple through and through. It is intense and honeyed, with echoes of pear-drops, simultaneously sweet and sharp. Of all the Cox offspring, Rubinette surely gets closest to having that elusive greatness. Interestingly, although the addition of the sweetness of Golden Delicious might be expected to make Rubinette sweeter than Cox, somehow this has not happened, and if anything Rubinette is slightly sharper than Cox - but the sweetness from the Golden Delicious gives a richness to the sharpness. In fact the balance of sweetness and sharpness is probably the best of any apple variety.
