How to Build a Wine Cellar
Thinking about building a wine cellar in your home? We've outlined the following important considerations and steps below to follow when constructing your wine cellar.
Step 1: Identify the Purpose of Your Wine Cellar
Will it be for functional long term storage or will it be a showcase for your wine? How many and what types of wine and bottles will you be storing? Knowing the answer to these questions will help you determine the wine cellar size that will meet your needs.
Step 2: Determine Your Wine Cellar Size
The size of your wine cellar will depend on how many bottles you wish to store and how much space you can devote to it. Our wine cellar construction charts are a great tool to help you understand the space you will need, the materials to use and the average construction costs.
Step 3: Determine Your Wine Cellar Location
The most important consideration when adding wine storage to your home is its location. A popular question we get is "Can I put a wine cellar anywhere in my home?" Yes, your wine cellar can be located anywhere in the home. You can convert a small room or closet or space under your stairs into a wine cellar. The most popular location is renovating your basement since it tends to be cooler.
The location you choose will determine many other factors affecting the cost of building the cellar and the cost to maintain the cellar. The ideal temperature and humidity for a wine cellar is in the 55°F and 60% relative humidity range. If you select a location that is cooler and more humid, it will require less work on the part of the cooling system and thus a smaller cooling system may be adequate. This should translate into lower energy costs. Conversely, if you chose to locate the wine cellar in a place that is warmer, the cooling system will run more frequently and a larger system may be required. Construction cost may also increase as considerations like additional insulation may be required.
Step 4: Wine Cellar Temperature
What Cooling System Works?
Your wine cellar should be placed in the coolest and most humid area in your home. The closer the wine room is to an ideal wine cellar temperature of 55° F and 60-65% Relative Humidity, the more efficient the cooling system will be. Any warmer and your wine will age faster; any cooler and your wine will age slower.
The location and size of the wine cellar will determine what cooling system is going to work best for the space. Some wine cellar cooling systems have strict requirements for installation. For example, a through the wall cooling system cannot vent directly into living space. So if your wine cellar is in the center of your living space, this system would not be a fit for you. A ducted or ductless system would be a better choice. The selection of and planning for a wine cellar cooling system should done prior to the wine cellar framing stage.Learn More About Wine Cellar Conditioning Learn More About Wine Cellar Humidity
Step 5: Do I Need a Vapor Barrier?
The application of vapor barrier is critical to the maintaining the correct environment and preventing moisture from forming inside your wine cellar walls. The method used will depend on what insulation material is being used.
- If traditional batting or rigid foam is to be installed, then you must wrap the walls and ceiling with a 6mil poly vapor barrier so the room is completely sealed.
- If the cellar is not in a basement, you will need to install the vapor barrier and insulate the floor as well. Be sure to tape all of the joints of poly with moisture resistant tape and be sure to seal all outlets and lighting fixtures that penetrate the barrier.
- Insulation isolates your wine cellar from exterior elements and helps to maintain a cool, moist environment for your wine. It will keep your passive cellar from becoming too warm and will help to conserve energy for a wine room that is actively cooled by a system.
- Non-cement floors with living or crawl spaces below must be insulated with rigid foam, spray-in insulations-preferably closed cell, or traditional fiberglass batting. Vapor barrier must also be applied on these surfaces as well.
- Walls must be insulated with a minimum value of R-19 and ceilings must be insulated with a value of R-30. R-value indicates the ability of the insulation to restrict heat flow — a higher R-value indicates better insulation.
- When applying traditional fiberglass batting, make sure to orient the paper or foil barrier toward the warm side of the wine cellar wall. Seal all joints with a foil-backed tape.
- When insulating your wine cellar, more is always better. Standard fiberglass rolls or batting provide an R-value of approximately 3 per inch.
Construction Material Thicknesses and R-Values
This chart shows the relationship of insulation values for sample wall thickness and material types. We recommend a minimum R-value of R-19 in the wine cellar walls and R-30 in the ceilings for any space dedicated to the proper cooling of wine.
|Wall Frame Thickness||Insulation Thickness||R-Value Fiberglass Batting||R-Value Rigid Foam|
Step 6: What Should I Frame and Insulate in My Wine Cellar?
Frame all cellar walls (even concrete walls) using standard 2x4 or 2x6 studs. Keep in mind the thicker the wall depth, the more insulation and higher R value can be achieved. You may even need to insulate the ceiling and floor depending on your substrate materials. Once the framing is complete, you will want to run the electrical and plumbing for lighting and your cooling system prior to insulating.
If you are using spray in closed cell foam insulation, this acts as a vapor barrier as well as an insulator so the 6 mil poly step in the vapor barrier process is not necessary.
Wine Cellar Construction Reference Chart
This chart helps you to determine the best construction guidelines for building your wine cellar.
|Construction Step||Recommended Specifications|
|Wall Framing:||2" x 6" @ 16" on center|
|Ceiling Framing:||2" x 8" @ 16" on center|
|Vapor Barrier:||6 mil polyethylene on warm side of walls and ceilings. Check your local building codes.|
|Wall Insulation:||R-19 minimum|
|Ceiling Insulation:||R-30 minimum|
|Sheathing:||DensArmor Plus® Interior Drywall is Vigilant's recommended sheathing. You can also use 1/2" moisture resistant green board with mildew resistant paint or tongue and groove wood paneling such as mahogany.|
|Flooring:||Moisture resistant material such as brick, tile, stone, or hardwoods.|
- Upon completion of the wall framing, run all electrical wiring for lighting, outlets and your wine room cooling system.
- Cooling systems normally require a dedicated circuit, so check the manufacturer's instructions and voltage requirements.
- Light switches with dimmers, if desired should be placed near the wine cellar door and should control all the lighting in the wine cellar. Switches with timers or motion detectors are a nice feature that can turn the lights off for you when your hands are full. This is the time to start thinking about what kind of lighting fixtures you would like and to have the wires run for them. Consider sconces, chandeliers, recessed lighting, can lighting and track lighting.
Step 7: Determine Your Materials
After the cellar is framed, sealed, insulated and all electrical and plumbing has been roughed in, you will chose your wall, ceiling and flooring materials.
- A moisture resistant drywall/plywood material is fine for walls and ceiling. We recommend DensArmor Plus® Interior Drywall. You can also use 1/2" moisture-resistant gypsum wall board or green board is the most common and cost effective wall material. This wall board must be painted with a moisture resistant paint.
- Rot resistant hardwoods are an attractive alternative and while more expensive to purchase and install, provide a superior appearance and require no long-term maintenance. Wood paneling works well for this also.
- For flooring, you want to choose a flooring material that will hold up in the cool humid wine cellar environment. Tile, stone and brick work well as does wine barrel flooring that is made from recycled wine barrel staves.
Step 8: Choose Your Entry Door
Your wine cellar entry door is the first chance to make a first impression. It should be both functional and beautiful. Because the wine cellar is a conditioned space, you want to make sure that the entry door is exterior grade with weather stripping for a tight seal. In the case of glass doors, make sure the wine cellar door includes high R-Value glass panels. Our Classic and Value Classic doors are the perfect solution.
It is preferable to have your wine cellar door swing into the wine cellar, but make sure that its swing path does not interfere with your wine racks. The positive pressure in a conditioned wine room will push the in-swinging door against the jamb and weather stripping, creating a superior seal. Before ordering your door you must determine its swing; in or out, and left or right. Make sure to provide this information to whomever you choose to manufacture your wine cellar door.
When choosing a door with a glass panel, make sure that the panel is dual paned, insulated glass. The higher the R-value, the better. All Vigilant glass doors include Argon filled, insulated, tempered glass panels that offer twice the R-value than standard insulated glass. If adding windows or sidelights to your wine room be sure they meet all of the same performance specifications as your wine cellar door.
Step 9: How Do I Begin The Wine Storage Design Process And Select The Proper Wine Rack Components?
First you need to determine your particular wine storage needs and preferences. Do you prefer individual bottle storage or bulk/bin storage? Do you need storage for wood wine boxes, large format bottles like magnums or split wine bottles? Are you looking to include wine display areas, tasting and decanting areas?
