Wine cellar construction is a building-science project before it is a design project. Every custom wine cellar we build follows the same seven-layer process: framing and rough-in, closed-cell spray foam insulation, interior finish, a properly sized wine cellar cooling system holding 55°F and 60 percent humidity, custom wine racking, an insulated glass wine cellar door, and low-heat LED lighting. Prestige Wine Cellars designs and builds custom wine cellars across Texas — Austin, Dallas, Houston, San Antonio and the Hill Country.
