How can I design a custom wine cellar in California?

Can I add a custom wine cellar to my restaurant in California?

Absolutely. We regularly collaborate with design professionals to create custom restaurant wine displays in California that are both functional and visually impactful. Our wine cellars and racking systems are designed to integrate seamlessly into a wide variety of commercial environments, including restaurants. 

From label-forward racks to full glass-enclosed commercial wine cellars, we help you showcase your wine list while maintaining optimal storage conditions in areas free of excessive vibrations or UV rays, both of which can harm your collection. Our solutions work for both new construction and renovations, with modular designs that accommodate your space and brand aesthetic. 

In addition to backbar storage, we offer wine storage displays for entryways, dining rooms, or wine cellar lounges—giving guests a memorable experience that reinforces your hospitality concept.

Where can I build a wine cellar in my California home?

With smart planning and the right design, a wine cellar can be integrated into nearly any part of a residential home. We’ve designed home wine cellars in California for basements, under-the-stairs alcoves, dining rooms, hallways, and converted closets—each tailored to fit the space and enhance the overall interior. Whether it’s an L.A. loft, a Sonoma estate, or a modern home in San Diego, our modular systems make it easy to create luxury wine storage that fits any lifestyle. 

We offer both modern and traditional California wine cellar design options, complete with climate planning and custom finishes. No matter the location, our designs facilitate both preservation and presentation, resulting in a high-quality cellar that feels like part of the home—not an add-on.

How big should a California commercial custom wine cellar be?

The size of a California commercial custom wine cellar depends on the wine list, service volume, and available space. For restaurants, bars, and hospitality venues, we recommend designing with both current inventory and future growth in mind. 

A wine wall behind the bar may only need space for a few hundred bottles, while a full wine cellar lounge or glass-enclosed walk-in display may hold thousands. With our years of experience in custom cellar design in California, we can advise you on the appropriate size range for a wine rack at your site.

Our team works with designers to optimize the bar layout and design by selecting modular racking that enhances the flow and guest experience. This enables us to create custom wine cellars in California that scale beautifully without compromising elegance or accessibility.

Do I need temperature control in my California wine cellar?

Yes—temperature control is essential for preserving wine quality, even in California’s relatively mild climate. Wine should be stored around 55°F with stable humidity to prevent cork shrinkage, oxidation, or spoilage. 

Our racking systems are compatible with a range of cooling units, which can be concealed within walls, ceilings, or cabinetry for a seamless finish. For long-term aging, daily service, or display, every luxury wine cellar deserves the protection of reliable, quiet, and discreet temperature regulation.
