Under-Stairs Wine Racks: Custom Oak Grid Systems for Wine Storage

A traditional oak diamond-pattern wine rack — where bottles are cradled in diagonal intersections of oak slats — maximises storage density and allows any bottle to be removed without disturbing others. Slat spacing for standard 750ml bottles is 90mm × 90mm internal diamond aperture. A 600mm × 600mm grid section holds approximately 12–15 bottles. For a typical under-stairs void depth of 1200mm and width of 1800mm at the front, a floor-to-soffit wine rack can accommodate 80–150 bottles depending on the available height.

The ideal wine storage temperature is 12–14°C with minimal variation. An under-stairs void in a well-insulated Berkshire home typically maintains 14–18°C — slightly warm for long-term storage of fine wines but acceptable for everyday drinking wines held for 6–18 months. Ventilation is important to prevent mustiness — a small grille at the bottom of the under-stairs door allows passive air movement. For serious collectors, a small dedicated wine cooler unit is better than relying on the under-stairs temperature alone.
