Wine cellars in Sonoma
For a Sonoma cellar, assess the enclosure before selecting the cooling unit. Whether the space is inside the house or in a separate building, Wine Hardware helps you bring room dimensions, conditions and storage plans together in a practical equipment discussion.

What we build here
Tell us what surrounds the proposed cellar and how the space is used now. Work with your contractor on the enclosure, and use the selected manufacturer’s requirements to guide the equipment installation.
Consider insulation, moisture control, penetrations and the door together. Final requirements depend on the room and equipment, rather than one standard recipe.
Share ambient conditions and possible equipment locations. Compare the actual model’s operating requirements with the finished room.
If power continuity matters to the collection, raise it during planning. Have a qualified professional assess any backup supply and confirm how monitoring behaves without power or internet.
How a cellar happens
Agree on the scope, equipment and current lead times before ordering. The schedule depends on the room, products and work your contractor needs to complete.
Where the wine will live, how many bottles you own now, and how many you expect in five years. Photos and a rough sketch are enough.
Dimensions, insulation, vapour barrier, glass area, power, and where the heat can go. This is the step that prevents expensive surprises.
Rack elevations, bottle count by bottle type, cooling options and finishes — reviewed before anything is ordered.
We supply racking, cooling, doors and refrigeration, and give your contractor rough-in notes for power, framing and condensate.
Review the layout and equipment instructions with your project team. Then bring your wine and accessory questions to Mike at the showroom to plan how you will stock and use the space.
The parts
All of it is stocked or ordered through the Walnut Creek showroom, and every one of them is a decision we can make with you before you buy.

VintageView metal, Modularack pine, redwood and mahogany designer kits, and fully custom millwork when the room refuses to be rectangular.

Compare Transtherm wine cabinets and Marvel built-in refrigerators when a full cellar room is more than you need. Check the exact model’s ventilation, access and bottle-fit requirements.

Corkscrews, preservation systems, decanters, tags and the small things that make a finished cellar usable on a Tuesday night.

Photographs flatten everything. Racking depth, the weight of a glass door, the actual noise a cooling unit makes at three feet — those you have to stand next to.
