Probably the one you have is "Pastillier" (Known) and Jason is talking about the "Unknown Pastillier" that is causing the drooling. It has not been verified yet if the "Unknown Pastillier" is a "Pastillier". There is chance that the two may be different varieties or different strains. I believe you may be rooting the "Unknown Pastillier" this year. Keep both and compare.
I got good green fruiting load last year on Unknown Pastillier but the frost came before the ripening. This winter I had decided to five this plant a place of honour on the south side of the wall to see if it will ripen in time. One thing I had found that it is more prone (sensitive) to frost damage than most others.
I was also tempted by the colour of the interior and bought cuttings in the winter of 2008. I always used go for a variety by the colour in pictures but now I have learned that the colour may not be the same in every climate and soil conditions so I have to be satisfied with faded colours as long as it ripens (& hopefully tastes good too).
Edit: BTW, mine did not drop the fruit at all. They were hard to pluck at the end of the season even after frost. Could be the climate?
