Why didn’t we think of this?! The unbelievably simple Wine Wedge makes runaway bottles a thing of the past. Use one rubber wedge to stack and store bottles against a wall, or use both wedges to create a pyramid (see picture below). You can safely stack six bottles of wine with one set of wedges – even on wire shelves. Just wedge it! The wedges are available in a multitude of colors and make a great gift for neat-freaks. Get the Wine Wedge at Amazon for $10.
