A gentile picks up an open container of wine, lifts it, but does NOT shake or tilt it. What is the law?
Halachah 2 (idx 1): If the gentile lifted the container but did not shake it or touch the wine itself, the wine is permitted even to drink. Mere lifting without movement of the wine is of no legal consequence.
Question 2
A gentile places his finger on the outside of a leaking barrel hole to stop wine from flowing out. What is the ruling for the wine BELOW the hole?
Halachah 10 (idx 9): The Rambam rules that wine below the hole is permitted to drink, since the gentile's power (stopping the leak) only affected the wine above the hole. Wine below was entirely untouched.
Question 3
A Jew leaves a gentile alone in his wine store but comes and goes throughout the day without informing the gentile of any long departure. What is the status of the wine?
Halachah 17 (idx 16): As long as the Jew departs and returns throughout the day without declaring a prolonged absence, the wine is permitted even to drink. The gentile is deterred by the constant possibility that the Jew will suddenly reappear.
Question 4
A person pours wine from an upper container into a lower container holding gentile wine. The two containers are connected by the flowing column of wine. What happens to the wine in the upper container?
Halachah 12 (idx 11): The flowing column of wine connects the upper container to the gentile wine in the lower one. As a result, all the wine remaining in the upper container becomes forbidden.
Question 5
A battalion of soldiers enters a city in peacetime. What is the status of wine stored in sealed barrels in the stores?
Halachah 24 (idx 23): While open barrels in stores are forbidden (soldiers freely help themselves), sealed barrels remain permitted. We can assume that had soldiers opened them for a libation, they would not have bothered to re-seal them.
