In this wall-mountable wine rack, a geometric diamond grid design offers a unique system for storing and displaying your fine wines. Made from mahogany plywood, a full-scale pattern is used to eliminate the guesswork when lining up the grid. Biscuit joinery is used throughout, and black-walnut is used to highlight the exposed front-edges. The contrast of the mahogany and walnut serves to highlight each storage compartment. For strength and rigidity, a back panel cut from 1/2-inch mahogany plywood is installed.
