Question:
If someone eats grapes and an apple, or Grapes and pistachios, does one make an BOREH NEFORSHES for the apples or pistachios as well as al HAETZ for the grapes, or does the AL HAETZ COVER THE APPLE /pistachios?
Answer:
When a person makes Al Haetz it includes the bracha achrona for all fruits, as all of them are from an eitz-tree. Therefore there is no need to make a Borei Nefashos on the apple or pistachios. This will not apply for vegetables that were eaten, and also will not work if he drank wine, since for that he will be saying Al Hagefen.
Best wishes
