Q. After eating a significant amount of grapes, I was ready to recite the Bracha Acharona. (End blessing). Out of habit and negligence, I started by saying ‘Al Hamichya,’ but before the end I remembered that I ate fruits and closed the Bracha correctly by saying ‘Al Haaretz Veal Haperos.’ Did I comply with the blessing or did I need to repeat it again and say the beginning also correctly?
A. Poskim disagree if you have to say both the beginning and the end correctly or if it suffices with the end. Bach (O.H. 208) quotes the Rashbah who maintains that it is enough to recite the end while the Rosh mentions you need both.
Since there is a disagreement in Halacha, one does not recite the Bracha in doubt. (Vesen Brocho 20: D: 3: p.359, and others).
Horav Shlomo Miller’s and Horav Aharon Miller's Shlit’a opinion is similar.
