This is the Amazing Balancing Wine bottle holder (it will also hold many 750mm olive oil bottles).
This one I made out of two exotic import woods. Walnut and Padauk as the center wood.
You simply put a standard size wine bottle in the hole and by adjusting how far you put the bottle neck in the hole you can have the bottle balance or have the bottle at just about any other angle. Instructions are included with the holder. It is a single bottle wine rack.
This is a great gift item. People are amazed when they see the bottle rock back and forth by itself after you give it a little push.
