This project was built and designed by Mike from Oregon Makers. It’s a clever wine storage solution that uses diamond-shaped compartments to organize bottles of all shapes, from Champagne to Bordeaux, while also giving your wine cellar a distinctive, professional look.
The design combines rustic style with practical efficiency, holding around 100 bottles in a full-size version or about 50 in a half-size. Whether you’re building a home wine collection or improving a cellar for clients, this is a smart way to do it.

Why Diamond Bins Work
Diamond bins provide flexible, open storage for various bottle types. Unlike traditional racks, which often only fit one shape or size, the diamond layout makes it easy to group bottles by type while keeping them accessible.
The geometric pattern also maximizes space and gives the cellar a clean, organized feel. The result is a system that’s both functional and attractive, especially in rustic or industrial-style environments.
Material Prep and Joinery Strategy
The build begins with milling down the lumber to manageable lengths. These boards are then pre-drilled at both ends to accept long screws that will later tie the angled pieces together.
Because each diamond compartment will carry the weight of multiple bottles, strong joinery is essential. Mike emphasizes the importance of securing each joint with long screws and good glue coverage to prevent flexing over time.
Forming the Diamond Shapes
Each diamond is created by joining two V-shaped halves at a 45-degree angle. To streamline this process, Mike uses a simple jig with a built-in glue relief notch. This jig allows the two parts to be clamped cleanly without excess adhesive spilling into the joint.
Once the basic diamonds are formed, three units are joined together, offsetting screw directions for added structural balance. This grouped approach improves strength and keeps the entire assembly stable under load.
Building the Outer Frame
After constructing the internal diamond grid, Mike shifts focus to the outer carcass that will house everything. The goal here is to create a crate-like shell that supports the diamond structure and gives it a finished appearance.
Pocket screws are used to join the base and side panels together, offering clean joints without visible fasteners. The style leans intentionally rustic—functional and solid, rather than refined furniture.
Gluing the Panels
The side panels are edge-glued using a plate joiner to keep them aligned. Once glue is applied, clamps are used to press the panels together until fully cured.
This technique ensures that the outer box stays square and that the joined boards remain flush. It’s an important step for both appearance and structural consistency.
Trimming and Sizing
After glue-up, Mike uses a track saw to trim the panels and ensure straight edges. He then runs each piece through the table saw to dial in the final dimensions and uniform thickness.
Proper sizing makes assembly much easier and keeps the entire project square and tight. It also improves the final presentation of the bins, especially if they’re meant to sit in a visible area of the home or cellar.
Final Assembly and Orientation
The diamond bin modules are installed at a 45-degree angle inside the case. A speed square is used during this process to verify that each section is properly aligned and that no rotation throws off the symmetry.
The top panel is intentionally sized to overhang the sides slightly. This design adds strength to the corners and braces the unit under the weight of the bottles.
Mike uses 3-inch screws to secure the top, driving them deep enough to reinforce the upper structure while keeping everything flush. This step pulls the entire unit together and locks the bin compartments into place.
Making a Half-Size Bin
To create a smaller version of the storage rack, Mike simply cuts the full-size bin in half. This creates two compact racks that are easier to move and fit into tighter spaces, while still maintaining the same storage functionality.
The half-size version can hold up to 50 bottles and is great for casual collectors or for placing in underutilized corners of a wine room. The clean geometry and efficient use of space are retained no matter the size.
Functional and Stylish Wine Storage
Diamond bins aren’t just a visual statement—they solve real problems. They make bottle retrieval easy, reduce wasted space, and accommodate a wide range of shapes without modification.
The build process is repeatable and straightforward with basic tools and thoughtful planning. Whether you’re making one or a full wall of them, the design scales up nicely for larger spaces.
