Evaluation
The highly attractive appearance of shape and colour is a special characteristic of Ferbleue. The very late ripening, large fruits are ideal for fresh eating because of their outstanding flavour. To produce good fruit size and intense taste timely fruit-thinning is strongly recommended. Noteworthy is also the long shelf-life on the tree as well as in storage.
