From orangepippin.com: "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. We have speculated that perhaps it is the rich influence of the parent of Golden Delicious - Grimes Golden - that has somehow been carried over into Rubinette. Whatever the cause, the balance of sweet and sharp in Rubinette is probably the best of any apple variety. MUCH MORE TOLERANT OF HOT CONTINENTAL SUMMERS IN THE U.S. THAN COX."
