Two turns after it is started, whatever is in the barrel goes to location 34, the long lake -- the player too, who is told so and arrives there. Then the barrel itself is put back in location 32, the elvenking's cellar, closed and full, emptied with printing off so that what spills is not reported, and given back its wine: it is ready for another ride. Tried in the simulator with the player in the barrel at the forest river and the timer at 2: two WAITs later the player was on the long lake's bank, held by nothing, and the barrel was in the cellar with the wine in it.
