Hilchot Berachot 4:9-10 (Making a beracha on food that’s not in front of you)
10:14 pm
If a new variety of wine is brought in the middle of the meal, does the original beracha of HaGafen suffice, or must you make a new beracha? What is the halacha if you do not have food in front of you when you make a beracha? What if you do, but it falls and is destroyed before you eat it?
