In a move part Escher, part why-didn't-we-think-of-that, comes the Dual Beer Glass. Crafted by Matthew Cummings of The Pretentious Beer Glass Company (gotta love the honesty), the cylindrical beer glass houses two separate chambers that meet at the lip. This clever design allows amateur bartenders to pour the perfect Half and Half, eliminating the need for a bar spoon to prevent the two beers from blending.
