Water pouring puzzles (also called water jug problems, decanting problems, measuring puzzles, or Die Hard with a Vengeance puzzles) are a class of puzzle involving a finite collection of water jugs of known integer capacities (in terms of a liquid measure such as liters or gallons).Initially each jug contains a known integer volume of liquid, not necessarily equal to its capacity. Puzzles of this type ask how many steps of pouring water from one jug to another (until either one jug becomes empty or the other becomes full) are needed to reach a goal state, specified in terms of the volume of liquid that must be present in some jug or jugs. By Bézout's identity, such puzzles have solution if and only if the desired volume is a multiple of the greatest common divisor of all the integer volume capacities of jugs. (Wikipedia).
Here we suppose the volumes simply add up when you mix wine and water. Enjoy this one! Next puzzle: http://www.youtube.com/watch?v=4rrt2mYW42k Solution: http://www.youtube.com/watch?v=OF5DzACObZk Previous puzzle: http://www.youtube.com/watch?v=hujqtbrLke8

Can You Solve The Diluted Wine Puzzle?
A servant has a method to steal wine. He removes 3 cups from a barrel of wine and replaces it with 3 cups of water. The next day he wants more wine, so he does the same thing: he removes 3 cups from the same barrel (now with diluted wine) and replaces it with 3 cups of water. The following
