Hilchos Brochos Perek Daled

5776- 4:9- When a group is drinking wine and a new, nicer bottle is brought, the brocho "hatov vehameitiv" (who is good and does good) is said. However, it is not said when one is alone. Why? because "hatov" goes on the person saying the brocho and "vehameitiv" goes on the other people at the table. If there are no other people at the table, there's no one for the "vehameitiv" to go on.
