Among the various wine storage solutions, having a custom wine cellar built in your home in California is the best choice to make. A residential custom wine cellar isn’t just a regular closet. It is specifically designed and constructed to keep wines safe, and to allow them to age properly.

Here are the things that you need to know when having a custom wine cellar constructed:


One of the very first things done when building a wine cellar is applying the insulation. All of your wine storage room’s walls and ceilings must be properly insulated, using fiberglass, polystyrene/rigid foam, or blow-in insulation. Thicker insulation is always better, because it means that the cooling unit will be more efficient in cooling the wine cellar.

The interior and exterior of the cellar should both have a minimum of R22 insulation, while the custom wine cellar’s ceiling ought to have at least R32. If your wine storage room is built at a location wherein the ceiling is directly exposed to the sun or strong winds, it recommended that a higher grade of insulation is applied to the ceiling.

Floor insulation is not always necessary. It is only needed if the flooring of the cellar might directly affect the temperature of the room. Your wine cellar builder will determine this for you. If it does affect the temperature of the cellar, 2” x 2” wooden sleepers should be installed with a rigid insulation of R7.5 in between them.

Vapor Barriers

Wine enthusiasts and wine collectors know that it’s not only temperature that should be controlled in a home wine cellar, but also humidity. Ideally, the humidity inside your wine storage room should be at around 70 percent. Part of controlling the humidity is installing vapor barriers before beginning the wine cellar construction. Having a vapor barrier applied in between the wall and the insulation also prevents moisture from developing outside the insulation. This moisture, when left without intervention, will cause mold to grow.

Generally, a 6 mm plastic with seams in between sheets is used for the vapor barrier. But the type of vapor barrier needed actually depends on the type of insulation used. For example, if the insulation applied is fiberglass batt, you need to have a 6 mm plastic vapor barrier applied. A lot of people think that the coated paper on some fiberglass batts are enough as vapor barrier, but this is not true. A 6 mm plastic vapor barrier is not needed if you use blown-in foam insulation. This spray-in foam is a type of insulation that also acts as its own vapor barrier.
