Know What You Want
What Do you Think About Before You Build a Wine Cellar in Contra Costa County?

As you think about your wine cellar in Contra Costa County, whether you are in Richmond, Concord, Walnut Creek, Pittsburg, Antioch, or Danville, you can be sure many things will be buzzing through your mind. Many companies offer services to help you through the process, including plans and designs that help you both design your wine cellar and spec out the quote. You’ll have to decide at what point you want to engage these wine cellar specialists. Will they build the cellar themselves? Will you renovate an area in your house, then have someone install racking? There are so many different choices. To help you evaluate who you’ll work with, it’s a good idea to have some questions prepared. That way, even when you get sidetracked by discussions, you’ll have to same set of questions to ask each one. The questions will also help you outline exactly what you’re looking for in a wine cellar.

  • Do I want a Diamond Certified wine cellar builder in Contra Costa County that is rated best in quality and backed by the Diamond Certified Guarantee?
  • Where in my house will I put my wine cellar?
  • Do I have electrical wiring, drain lines, or water lines in the area where I want to put my wine cellar?
  • What are the heat and humidity conditions around my house year round? How hot does it get at the hottest?
  • Do I have an area adjacent to my proposed wine cellar where I can vent hot air?
  • Do I have ducting or want to install ducting?
  • How big is the space where I am planning to put my wine cellar?
  • How big is my collection of wine and how much do I plan to add to it?
  • What’s important to me- do I want to store wine without scratching the bottle or tearing the label, or do I want to focus on having the most bottles in the smallest space?
  • Do I have oversize or unusual bottle shapes? How many? Do I plan to increase the number?
  • Do I want a free standing wine cellar or a built-in wine room?
  • Do I want to keep wine over time to age or do I want to store some bottles for about a year so that they are always ready for drinking?

What To Ask In Person
Speaking With Your Contra Costa County Wine Cellar Vendor In Person

Once you’ve narrowed your choices, you’ll be taking off for Walnut Creek, Concord, Antioch, Pittsburg, Richmond, Martinez, Pleasant Hill, or wherever the best possibilities lie. Once you get there, you’ll be able to get more detailed information out of the wine cellar vendors. Again, it will help if you have a list of prepared questions so that you can approach your vetting in a uniform way. Below are some questions you might want to ask in person:

  • Who on your staff will help me design my wine cellar?
  • Can you show me some samples of the rackings you offer? What kinds of woods and finishes are available?
  • Can you show me different lighting styles you have implemented for wine cellars and wine storage racks? (Spotlights for specific wine bottles, back lighting for wine racks, overhead lighting for wine cellars, etc.)
  • How long will it take to design my wine cellar if I work with you?
  • What kind of stains and lacquers do you use on your wooden wine racks? Are they water based with few VOCs, or are they oil-based?
  • Can you show me examples of previous wine cellars you have built?
  • Can I see different design styles of wine cellars and wine cabinets you have built in Contra Costa County?

  • What To Ask References
    Sample Questions for References of Local Wine Cellar Contractors in Contra Costa County

    It’s best to choose a Diamond Certified wine cellar contractor in Contra Costa County because all certified companies have passed an in-depth ratings process that most others can’t pass. If you want quality from a wine cellar vendor in Contra Costa County, you can have confidence choosing a Diamond Certified company. Diamond Certified reports are available online for all certified companies. And you’ll never be fooled by fake reviews, because all research is performed in live telephone interviews of actual customers.

    If you can’t find a Diamond Certified wine cellar vendor within reach, you’ll have to do some research. If you do, call some references provided by wine cellar contractors in Contra Costa County. Remember, references provided to you by the wine cellars are not equal in value to the large random sample of customers surveyed during the Diamond Certified ratings process. That’s because references given to customers from companies are cherry-picked instead of randomly selected from all their customers. So the contractors will likely give you a few customers to call that they know are satisfied.

    If you do call references on your own, specifically ask for a list of the company’s 10 most recent customers. This will help avoid them giving you the names of only customers they know were satisfied.

    • Were you satisfied with your new wine cellar? If not, what didn’t you like about the process or the result?
    • What kind of wine cellar did you build? Was it for storage only or do youhave social space in it?
    • What kind of cooling system did you install? What about it do you like or dislike?
    • Are you having any difficulty maintaining the proper humidity? Do you use a fountain for humidity or does your cooling unit monitor and manage humidity along with temperature?
    • How big is your wine cellar and how long did it take to get it built?
    • Did you have any delivery problems with material not showing up on time from the Contra Costa County wine cellar vendor?
    • Did you find your wine cellar vendor offered the range of materials that you wanted or did you have to go to several places to get everything? If you went to other places, what materials did you get from other places?
    • Did your wine cellar vendor seem knowledgeable about wine in general? Did you feel comfortable taking advice from the vendor?
    • How much of the cellar design did you do and how much did the vendor do? Were you satisfied with the ratio?
    • Was your wine cellar completed on time and on budget? If not, what happened so that it got off track?

  • Review Your Options

  • How To Work With
    Before You Work With a Contra Costa County Wine Cellar Vendor

    Whether in Antioch, Richmond, Concord, Walnut Creek, or Pittsburg, you’ll find the best vendors if you do a little homework first. Look for vendors who have worked with spaces similar in size to your own. If you have an apartment, you can find vendors who have lots of experience in building wine cellars in smaller spaces.

    Similarly, if your wine cellar will be on a larger scale, you would probably want someone accustomed to designing for a large space.

    The practicalities are even more important than the aesthetics when it comes to preserving and aging wine over the long run, so look for someone who can offer sound advice about cooling systems, humidity management and the nuts and bolts of construction – insulation advice, what utilities will need lines run into the cellar and the like. Look for a firm that uses licensed technicians when needed and that complies with construction laws.

    Getting Along with Your Contra Costa County Wine Cellar Vendor
    You can take some steps to smooth the process of working with wine cellar vendors in Contra Costa County. You can identify where you want to put your wine cellar – whether it’s new construction or a renovation. Gather information about the size of the wine cellar – approximate dimensions or exact, if you are renovating. Take temperature and humidity readings so you know the state of the space before work begins. If you are thinking about venting to the outdoors, make a note of that.

    If you are thinking of exhausting to another room, check its normal temperature and check for its air movement and ventilation options. Try to gather data about how temperatures vary across the seasons in your neck of the woods.

    How big is your current collection and how do you plan to expand it? How soon? Note the bottle shapes you own. Are they Bordeaux or Pinot Noir bottles? Do you have or plan to add oversized bottles? Are you seriously concerned with keeping the bottle from scratching and the labels from tearing? Or could you live with it if a label got torn or a bottle scratched? Considerations about bottle conditions can help you decide if bin storage is ok for you or if you really want individual storage.

    Know how you want to use your space. Is it only for storage or do you plan to hold tastings in it? In short, the more you know about your space and your collection, the easier the process will be. If you have a particular design aesthetic, you can help your design consultant by describing it and particularly by bringing pictures of things that please you.

Check The Work
Check Your Contra Costa County Wine Cellar Vendor’s Work Against the Invoice

How you decide to build your wine cellar will influence the number of people you are dealing with. If you build your wine cellar yourself, you’ll be acting as the contractor, but you’ll be working with wine cooling unit vendors for equipment and with wine cellar vendors for racking, most likely. If you don’t build your own cellar, then you may work with a contractor to build the cellar and with a wine cellar vendor to place the racks, lighting and other equipment. Or you may work with a wine cellar vendor who undertakes the entire process.

Keep track of who is responsible for which tasks and pieces of work. Each should provide an estimate or quote for the work done. You’ll need to ask for a time estimate, as well. You’ll need to track progress to make sure the work is being complete as quoted on the invoice and that the proper materials are delivered. You’ll need to track any utilitywork that is done to support your new wine cellar – for instance the installation of electricity, water lines or duct work. You’ll also need to track that the wine racks, display cases, and lighting are delivered as described.

You are working on a big project, there’s no denying that – new wine cellar construction has all the elements of any construction project plus the complications of wine storage thrown in.

You need to know what your project entails – Wine storage design? Utilities? Wine racking? Lighting? Flooring? Ceiling? Make sure the utilities are run to match the lighting design – i.e. do you have lines where you have switches designed? For each piece of the project, you should note who is responsible for delivery, when the delivery is promised, and how to contact that person. You should also note any dependencies – for example, construction of the walls needs to be complete before you can install racks.

If you track the elements of the room and their dependencies on each other, or have a trusted installation team that is doing it for you, you’ll have a successful build. For any equipment installed – cooling units, racking, lighting – and for any services provided, such as electrical lines run, make sure you get the warranties and understand what each warranty covers.

When you have complaints against the provider of the wine racks or the cooling unit or other material providers, try to resolve the complaint with the provider first. If you cannot resolve the complaint there, you can go with the small claims court process.

Top 10 Requests
Top Wine Cellar Building Service Requests

The wine community is large and enthusiastic. When you want to store wine, there are a few requests that commonly rise to the top of the list.

Store Wine
To really store wine properly, the wine must be in an environment where the temperature does not significantly fluctuate and where a proper humidity is maintained. Storing wine properly allows it to maintain its true character, as the cork does not shrink and the wine is protected from improper exposure to oxygen.

Keep Wine Ready for Serving
A wine cellar does not really keep wine ready for serving. For this scenario, you probably want a wine refrigerator or wine cabinet, which stores wine for about a year.

Bring Wine to Temperature
A wine chiller is used to bring one or two bottles to the correct serving temperature. A good wine chiller respects the humidity demanded to keep the cork intact and replaces the option of popping the bottle into a standard refrigerator.

Enjoy Wine Tasting with Friends
A wine cellar can be used as a tasting space, if designed to incorporate a tasting area. This brings a social dimension to the wine cellar and makes it more than a storage room.

Display Rare or Unique Wine Bottles
Wine cellars can incorporate special display stands or cases that allow you to highlight special bottles.

Age Wine
Wine cellars are designed to allow users to age wines over time in a controlled environment. One of the pleasures of the practice is get a case of wine and see how it develops over time, perhaps having a bottle or two per year to see how the wine changes.

Frequently Asked Questions
FAQ for Clients of Wine Cellar Construction Companies

Q: Why choose a Diamond Certified wine cellar contractor?
A: Diamond Certified helps you choose a wine cellar company with confidence by offering a list of top-rated local companies who have passed the country’s most in-depth rating process. Only wine cellar vendors rated Highest in Quality earn the prestigious Diamond Certified award. Most companies can’t pass the ratings. American Ratings Corporation also monitors every Diamond Certified company with ongoing research and ratings. And your purchase is backed by the Diamond Certified Performance Guarantee. So you’ll feel confident choosing a Diamond Certified wine cellar builder.

Q: Do I need a custom designed wine cellar?
A: You can construct a wine cellar using standard materials. You can even get kits that allow you to build the units – racks, shelves, displays – that go into your new wine cellar. “Custom” means many different things in the wine cellar world. It may refer to special woods or cuts of wood that are different from standard offerings. It may refer to special stains, lacquers or paints. It can also refer to special pieces of furniture within the wine cellar, or specially cut and beveled rack edges. Custom installations may involve a higher price point. Make sure you are paying for something you want and that fits your exact specificiations.

Q: What makes a new wine cellar different from normal construction projects?
A: Wine cellars need to stay between 55-58 degrees and they need to have humidity levels of 55% to 75% relative humidity. This makes them cooler than most rooms in your home but also much more humid. The construction of your wine cellar needs to take the additional humidity into account, by having the correct insulation or vapor barriers, machines to cool the air, and ways to introduce and control humidity. The materials your Sonoma County wine cellar builder uses to construct and furnish the wine cellar must also be humidity resistant, which rules out carpet or vinyl, since the one will rot and the latter will not stick to its underlayer.

Q: Why do I need an exterior door on my wine cellar?
A: Your wine cellar is trying to maintain a steady temperature and humidity level, which are different from the rest of your house. An interior door is not sturdy enough to prevent the passage of heat and humidity. You need not only an exterior quality door, you should also surround the top and sides with weather stripping and use a threshold and sweep on the bottom of the door.

Q: What is a passive wine cellar?
A: A passive wine cellar is one in which temperature and humidity controls are not introduced. The wine cellar relies on natural conditions – such as being underground or in a cave – to provide an appropriate climate for the wine.

Q: Does my cooling unit also control humidity?
A: This is one where you have to pay attention to the unit you are installing. A few units may also monitor humidity, but most do not have the ability to add humidity to the air when needed. In these cases, you may need a fountain to add moisture to the air.

Q: There are so many terms. What is a wine cellar exactly?
A: A wine cellar is room – not necessarily in the cellar – where wine can be stored in controlled temperature and humidity conditions over the long term. This is in contrast to a wine refrigerator, which is used to store wine for about a year. Some stand-alone or free-standing wine refrigerators are called wine cellars. You should speak with the vendors about the prospect of storing wine in these machines over the long term. Wine refrigerators are also called wine vaults or wine cabinets.

Wine refrigerators come in different capacities for holding different numbers of bottles. Some are single zone, meaning they only allow you to set one temperature. Others are dual zone, allowing you to set two temperatures, for example so you can store red and white wines at different temperatures.
Wine refrigerators also come with compressor technology, which uses a condenser coil like a normal refrigerator and evaporates off water during the change from liquid to gas and back again. Compressor types are usually recommended for larger containers. Thermoelectric machines use the Peltier effect and have a hot and cold element inside, pushing the heat away from the cold. They tend to use less energy and have no vibrations. Compressor technology does have some vibration, which some claim can damage wine.

Q: What’s green board and what’s it doing in my wine cellar?
A: Green board refers to a type of drywall that is usually built into bathrooms and kitchens. It is designed to resist water. This makes it good building material for a wine cellar, where the humidity is high.

Q: Why can’t I just put my wine in a normal fridge?
A: While some wine refrigerators use the same compressor technology as normal refrigerators, the humidity is the critical factor. Standard refrigerators keep humidity very low – much lower than the 55%to 75% relative humidity that wines need. Wines need the high humidity to keep the corks in good shape. Without the humidity, corks will shrink, allowing in oxygen, which will destroy the wine, and any smells that surround the wine.

Q: How do I design a new wine cellar?
A: You can design a wine cellar on your own or look for examples of wine cellars and copy them. You can find kits to assemble different parts of a wine cellar. You can also work with wine cellar specialists in Sonoma County. Often they will provide detailed plans as part of the quoting process. These wine cellar designers often use CAD software to produce drawings and specifications of your wine cellar.

Q: Can I put a wine cellar anywhere in my house?
A: In general, yes, but there are some things you should consider. If you are going to build a passive wine cellar, then you need to build where the heat and temperature will suit long-term wine storage. In a passive wine cellar, you do not introduce machines or devices to control heat and humidity.
In a controlled wine cellar, you will be using machines to control heat and humidity, so you want to consider the existing heat and humidity in the space. Are there spaces where you can easily vent heat from the wine cellar? Do nearby rooms have the ability to move and exhaust air if the cellar is vented into them? If you are venting outside, do you have the necessary ducting or do you need to install it? For the unit you are buying, how long can the ducting be? If you plan on a split system, do you have a safe place to handle the outside unit.
