The beer flows down the fall, and then all winter long.
But these days the German peasants are too lazy to tote wooden buckets, so they just hook up plastic tubing and let the beer flow downhill to where they fill the barrels.
The happy German peasants in their native costumes tapping the trees as the beer rises through the trees in the autumn, bringing it home in buckets, then celebrating with the Oktoberfest.
