Bar Refrigeration

Commercial Bar Refrigeration

Commercial bar refrigeration covers the family of NSF-certified cooling equipment purpose-built for the space behind the bar: back bar refrigerators (also called back bar coolers), bottle coolers, draft beer keg coolers, and shallow-depth back bar units for narrow service wells. These units are engineered for the bar duty cycle, which is very different from a kitchen: doors open and close hundreds of times a shift, product needs to stay cold and photogenic, and the entire cabinet has to fit under a 42-inch bar top without blocking the bartender's workspace.

At The Restaurant Warehouse we stock 35 pieces of bar refrigeration from Atosa, spanning 23-inch to 90-inch back bar coolers in solid and glass door, bottle coolers from 24 inches to 80 inches, and keg coolers from single-keg 23-inch units up to 90-inch four-keg cabinets. Every model runs on 115V, ships free to the contiguous 48 in 1 to 3 business days, and includes the standard Atosa 2-year parts and labor warranty plus 5 years on the compressor.

Back Bar Refrigerators, Explained

A back bar refrigerator (sometimes called a back bar cooler) is a low-profile refrigerated cabinet 34 to 37 inches tall built to slide into the back service well of a bar. The cabinet holds bottled beer, wine, mixers, and prepped garnishes at food-safe temperatures and is topped with a stainless work surface so the bartender can build cocktails, plate garnish trays, and stage service items without leaving the well. Widths run from 23-inch single-door units up to 90-inch four-door cabinets. Doors come in solid stainless for bulk storage or glass for merchandising.

Solid door back bars are the workhorse: better insulation, lower energy draw, no cabinet heat gain from bar lighting. The Atosa MBB series (MBB23GR through MBB90GR) covers the full width range. Glass door back bars put bottled product on display and drive impulse sales at eye level, at the cost of slightly higher operating expense and more careful lighting. The Atosa MBB48GGR, MBB59GGR, MBB69GGR, and MBB90GGR are our most-shipped glass door units. For narrow service wells where a standard 27-inch cabinet cannot fit, the shallow-depth Atosa SBB series is roughly 22 inches deep and available in solid, glass, and black finishes.

Bottle Coolers vs Back Bar Refrigerators

A bottle cooler is a horizontal top-load or top-hinged refrigerator built to hold beer bottles or cans directly on their side or upright with the pour spout accessible through a sliding top lid. Bartenders reach down for the bottle instead of pulling a door open. The format is faster in a high-volume beer bar and keeps beer visibly stocked. Sizes run 24-inch, 36-inch, 50-inch, 65-inch, and 80-inch (Atosa MBC24GR through MBC80GR).

A back bar refrigerator, by contrast, uses conventional swing doors and stores product upright on shelves. Back bars work better for wine, mixers, prepped juice bottles, and mixed inventory. High-volume beer-focused operations often run bottle coolers on the guest-facing side and back bar refrigerators on the bartender-facing side for prep and specialty product.

Draft Beer Keg Coolers

A keg cooler (also called a direct draw keg refrigerator) is a refrigerated cabinet sized around a half-barrel or sixth-barrel keg, with a tap tower mounted through the top for direct pour. The Atosa MKC lineup covers single-keg (MKC23GR $1,464), double-keg (MKC58GR $2,537), triple-keg (MKC68GR $2,854), and four-keg (MKC90GR $3,283) configurations. All units include a stainless top, standard three-inch tap tower cutouts, casters, and NSF certification.

For remote draft systems (long beer lines from a walk-in beer cave to a distant bar), a walk-in cooler with glycol lines is the right architecture; a direct-draw keg cooler is for bars where the tap tower sits directly above the keg. If the tap tower will be more than about 6 feet from the keg, plan on remote refrigeration to keep the beer cold to the faucet.

Shallow Depth Back Bar Refrigeration

Older bar builds and remodels often have service wells too narrow for a standard 27 to 30-inch deep back bar cabinet. The Atosa SBB shallow-depth series solves that with a 22-inch cabinet depth and the same 34-inch bar-fit height. Available widths are 48, 59, and 69 inches with solid, glass, or shallow-glass-slider door options in both stainless (AUS1) and matte black (AUS2) finishes. If your existing bar has a 24-inch service well or less, measure before ordering: even shallow-depth units need a couple inches of front and back clearance for compressor airflow.

Sizing Bar Refrigeration to Your Volume

1. Count Bottle Positions, Not Cubic Feet

Bar refrigeration is spec'd by how many longnecks, wine bottles, or kegs it holds, not just cubic feet. A 48-inch back bar cooler typically holds 150 to 190 bottles of beer standing up; a 50-inch bottle cooler holds around 300 bottles laid down. Match holding capacity to your peak-hour beer count with 25 percent buffer for weekend surge.

2. Measure the Service Well

Standard back bars are 27 to 30 inches deep; shallow-depth units are 22 inches. Measure your service well depth, height under the bar top (usually 34 to 37 inches), and available width in linear feet. Verify that door swing does not block the bartender's landing zone.

3. Ventilation Matters More Behind a Bar

Bar service wells are often boxed in by cabinetry, ice bins, and speed rails. Rear-breathing compressors will overheat in a boxed well; front-breathing units are the safer spec. Every Atosa MBB, MBC, MKC, and SBB unit is front-breathing, which is why they dominate the bar retrofit market.

4. Confirm the Electrical

Every unit in the collection runs on 115V/60Hz with a NEMA 5-15P plug. Put each cabinet on its own dedicated 15-amp circuit; sharing with dishwashers, blenders, or POS terminals will drop the compressor mid-service.

Beer Style Guide for Bar Operators

The style of beer you serve should inform how you refrigerate and pour it. Different styles have different ideal serving temperatures, carbonation levels, and storage needs — and matching the equipment to the style is the difference between a beer program customers rave about and one they tolerate. Below is a quick guide to popular craft beer styles, their character, and how to hold them in your back bar cooler, bottle cooler, or draft system.

American Pale Ale (APA) & Extra Special Bitter (ESB)

English-style pale ale and Extra Special Bitter (ESB) are medium- to medium-high-bodied beers with balanced maltiness, residual sweetness, and moderate-to-high hop bitterness. They feature earthy, herbal English hop character and fruity yeast-derived esters. American Pale Ale amplifies the hop side with citrus and pine notes. Serve at 45 to 50°F in a shaker pint or nonic pint glass. Hold in a back bar cooler or bottle cooler at standard beer service temperatures (36 to 40°F cabinet, warming slightly on pour).

American Brown Ale

American Brown Ale has medium-intensity roasted malt, caramel, and chocolate notes with low-to-medium hop flavor and floral or citrus hop character. Bitterness ranges from medium to high — more hop-forward than British brown ales while retaining balanced malt. Serve at 45 to 50°F in a shaker pint or English pint glass. A standard back bar cooler at 36 to 40°F is the right cabinet.

Double / Imperial India Pale Ale (Double IPA)

Double IPAs have intensified hop bitterness, flavor, and aroma from heavy hopping, plus a richer, more complex malt profile with toasted or caramelized notes. Medium-high to full-bodied with higher ABV than a regular IPA (typically 7.5 to 10.5% ABV). Fresh hops matter — Double IPAs degrade quickly, so plan for rapid rotation (2 to 6 weeks max at cold storage). Serve at 45 to 50°F in a tulip, snifter, or IPA glass to concentrate hop aroma. Store cold at 36 to 40°F in a back bar cooler and rotate stock aggressively.

American Stout

American stouts feature coffee- and chocolate-forward flavors, citrus-derived American hop aroma, and a distinctive dry-roasted bitterness in the finish. Oatmeal versions add body, smooth creamy texture, and head retention. Dark-roasted barley distinguishes them from porters. Serve slightly warmer, at 50 to 55°F to open up the roasted malt aromas. Nonic pint or tulip glass. Standard back bar cooler storage is fine — stouts are more forgiving on hold time than hop-forward styles.

Robust Porter

Robust Porter is bold and roasty, balancing roasted-malt bitterness, black-malt sharpness, caramel sweetness, malty sweetness, hop bitterness, and cocoa-like notes. Falls between a brown porter and a stout, without prominent roast-barley flavor. Serve at 50 to 55°F in a nonic pint or tulip. Standard cold storage in a back bar cooler or draft system.

Belgian-Style Saison

Belgian-style saisons are highly carbonated, bottle-conditioned beers with subtle yeast character and a broad flavor range: citrus, tropical fruit, earthy or funky notes, horse blanket, and leather. Specialty spices like coriander, black pepper, sage, and thyme are common. Because saisons are bottle-conditioned, upright bottle storage matters — keep them upright in a bottle cooler or on shelves inside a back bar refrigerator so the yeast settles at the bottom. Serve at 45 to 50°F in a tulip or Belgian goblet.

American Brett Beer

Brett beer, or Brettanomyces beer, is distinct from sour beer and may range from non-acidic to acidic. It commonly features funky, earthy, horsey, goaty, leathery, phenolic, and fruity aromas. Because Brett continues to evolve in the bottle, keep cold (36 to 40°F) to slow secondary fermentation and hold in an upright position if bottle-conditioned. Serve at 45 to 55°F in a tulip or Teku glass to concentrate the funk aromas.

Beer Storage Summary by Format

Matching Bar Refrigeration to Your Beer Program

Choosing the right cabinet depends on your beer format mix:

• Mostly bottles and cans: a back bar cooler is the standard behind-the-bar workhorse — glass-door for merchandising, solid-door for storage.
• High-volume bottled beer service at the well: a horizontal bottle cooler puts product at the bartender's fingertips with top-load access.
• Draft beer program: a draft beer cooler or kegerator holds one to four kegs at proper temperature with a direct draw tower.
• Mixed program with bottles, cans, and kegs: pair a back bar cooler with a draft beer cooler at opposite ends of the bar so bartenders have short-path access to every format.

Every unit above ships free to the contiguous 48 in 1 to 3 business days with the standard Atosa 2-year parts and labor warranty plus 5 years on the compressor.

Frequently Asked Questions About Bar Refrigeration

What is a back bar refrigerator?

A back bar refrigerator (also called a back bar cooler) is a low-profile refrigerated cabinet 34 to 37 inches tall built to slide into the back service well of a bar. It holds bottled beer, wine, mixers, and garnishes at food-safe temperatures and is topped with a stainless work surface for cocktail building. Widths run from 23 inches up to 90 inches with solid or glass doors.

What is the difference between a bottle cooler and a back bar refrigerator?

A bottle cooler is a horizontal top-load unit that holds beer bottles laid down with the pour spout accessible through a sliding lid; the bartender reaches down for the bottle. A back bar refrigerator uses swing doors and stores product upright on shelves, which works better for wine, mixers, and mixed inventory. High-volume beer bars often run both.

What is a keg cooler?

A keg cooler (or direct-draw keg refrigerator) is a refrigerated cabinet sized around a half-barrel or sixth-barrel keg with a tap tower mounted through the top for direct pour. Atosa MKC units come in single (MKC23GR), double (MKC58GR), triple (MKC68GR), and four-keg (MKC90GR) configurations.

What is a shallow depth back bar cooler?

A shallow depth back bar cooler is roughly 22 inches deep instead of the standard 27 to 30 inches. It fits narrow bar service wells found in remodels and older builds. Atosa SBB models are available in 48, 59, and 69-inch widths with solid, glass, or shallow-glass-slider doors and stainless or matte black finishes.

How much bar refrigeration do I need?

Spec by bottle count, not just cubic feet. A 48-inch back bar cooler holds roughly 150 to 190 upright bottles; a 50-inch bottle cooler holds around 300 laid down. Match to your peak-hour bottle turn with 25 percent buffer for weekend surge, and add a keg cooler if you run draft.

Do bar refrigerators need special electrical?

Every unit in the collection runs on standard 115V/60Hz with a NEMA 5-15P plug. Put each cabinet on its own dedicated 15-amp circuit; sharing with dishwashers, blenders, or POS terminals will kill the compressor mid-service.

Are Atosa back bar refrigerators NSF-certified?

Yes. Every MBB, MBC, MKC, and SBB unit is NSF/ANSI 7 certified for commercial food-safe cold storage and ETL/ETL-Sanitation listed. All units are front-breathing so they can install flush in a boxed service well.

What warranty comes with Atosa bar refrigeration?

Atosa bar refrigeration ships with a 2-year parts and labor warranty plus 5 years on the compressor. Register with Atosa within 30 days of install to keep extended coverage valid.
