Cold brew concentrate already exists somewhere in your workflow, bought as bag-in-box from a roaster or brewed in-house. This guide is about serving it, not making it: how the concentrate moves from container to cup, the thing most buying guides skip. Already brewing your own? See our guide to commercial cold brew makers instead.
The picks below are compared from manufacturer spec sheets and verified live product listings, not hands-on tested, so confirm current specs before you buy.
Who this is for, and who should skip it
This guide is for a cafe that already has concentrate, bought as bag-in-box or brewed on an immersion system, and needs to hold and pour it. Still deciding how to brew from raw coffee? Start with the commercial cold brew maker guide instead. Skip the proportioner and keg-tap tiers if you’re pouring cold brew a few dozen times a day and a barista already dilutes each cup; a gravity dispenser handles that without a nitrogen tank to manage. Reach for a proportioner or pressurized tap once volume makes ratio consistency a real problem, or you want a self-serve line where nobody measures.
Which dispensing mechanism fits your cafe?
No buying guide sorts this category by how concentrate moves from container to cup, so here it is, matched to volume and budget.
| Mechanism | How it works | Ratio control | Price tier | Certification | Best fit |
|---|---|---|---|---|---|
| BIB proportioner | Metering valve blends BIB concentrate with water on demand | Fixed, machine-set | Mid to premium | NSF/ETL listed (dispensing-valve standard not specified) | High volume, self-serve, drive-thru |
| Keg / pressurized tap | Refrigerated keg, nitrogen or CO2 pushes concentrate through | Set at fill time | Entry to mid | NSF-7 cabinet; NSF-18 tap-kits sold separately | Steady pour, willing to own a nitrogen tank |
| Gravity insulated | Pre-mixed concentrate and water, spigot does the work | Set at mixing time | Lowest in category | NSF listed vessel | Low volume, catering, market stalls |
| Premix agitated | Premixed to final strength; paddle prevents separation | Set at mixing time | Comparable to keg tap | cULus and NSF | High-volume finished-drink service |
BIB proportioners: the precision-ratio picks
A proportioner mixes concentrate and water inside the machine at a fixed ratio, rather than relying on someone pouring by eye.

Precision concentrate-to-water proportioner, narrow footprint
BUNN Refrigerated Liquid Coffee Dispenser (34400.0037, LCR-2 family)
- Refrigerated holding
- 38 to 42°F cabinet temperature
- Concentrate format
- 0.5-gal and most 1-gal BIB containers
- Dispense rate
- 1.8 to 2.5 oz/sec; ratio 25:1 to 65:1
This is the only dispenser here built to hold a fixed ratio no matter who's working the counter, and it does it in a narrow footprint that fits a tight bar. One thing to check before you order: it's built around BUNN's Scholle-valve BIB convention, so make sure your roaster's connector actually matches.

BIB proportioner and nitro tap in one unit
BUNN NITRON Cold Draft (51600-series)
- Concentrate format
- 1-gal BIB, yields 5 to 13 finished gal
- Ratio range
- 4:1 to 12:1, water/nitro to concentrate
- Certification
- NSF and ETL listed
A true proportioner and a nitro tap live in one cabinet here, so adding nitro to the menu doesn't mean buying a second machine. It costs accordingly: foodservice pricing runs well into four figures, the premium end of this whole category for a small cafe. BUNN's commercial warranty reportedly excludes non-commercial use too, so get that in writing from a dealer before you sign.

Keg and pressurized taps: steady pour speed all shift
Gravity dispensers slow as the container empties. A pressurized keg tap sidesteps that: nitrogen or CO2 holds a constant pour from full to empty. That’s really the whole reason to pay more for this mechanism.
Nitrogen-pressurized keg dispenser, budget tier
Kegco Cold Brew Coffee Kegerator (Javarator, ICZ163S-1)
- Keg capacity
- Three 5-gal, one quarter/half-barrel, or two sixth-barrel kegs
- Dispensing
- Nitrogen pressure; ships with tank and regulator
- Certification
- CSA-certified NSF/ANSI-7 (cabinet, not NSF-18 dispensing)
Pressurized dispense here runs roughly a quarter to a tenth of what a BUNN NITRON costs, and the same cabinet doubles as a standard beer kegerator. It's not complaint-free: multiple owners report freezing when Deep Chill runs a full 24 hours, and a few mention cooling fading after five years. Those are real reports, but a minority against otherwise positive reviews.
Specs: Kegco.com product page, model ICZ163S-1
Dual-tap cabinet, still and nitro on one unit
Summit Appliance 24 Inch Cold Brew / Nitro Coffee Kegerator (SBC7BRSCM2)
- Keg capacity
- Two 1/6-barrel (sixtel) kegs
- Certification
- ETL-S listed to NSF-7 standards
- Included hardware
- Nitrogen tank, regulator, dual tap kit
Dual taps out of the box mean one cabinet runs still cold brew and nitro side by side, no second unit needed. The tradeoff is nitrogen tank swaps instead of a plug-in appliance you can ignore. I didn't turn up model-specific owner complaints for this one; that's just what the record shows, not a gap I'm smoothing over.

Gravity insulated dispensers: the no-electricity entry point
A gravity dispenser holds pre-mixed concentrate and water and lets a spigot do the work, no motor, no BIB fittings to match. It’s a serving vessel, not a cooling device: keep it refrigerated or on ice and follow standard cold-holding limits.
Gravity, non-refrigerated, lowest cost of entry
Cambro Insulated Beverage Dispenser (Camtainer line)
- Construction
- Double-wall polyethylene, polyurethane foam insulation
- Spigot
- Drip-proof recessed spigot
- Certification
- NSF listed
Zero electrical draw, zero moving parts, and the cheapest entry point here, portable enough to pre-batch overnight and carry to a counter. Some owners report a leaking spigot after over-tightening. Worth remembering either way: this holds temperature, it doesn't create it, so whatever goes in should already be cold.
Specs: Retailer spec aggregation corroborated across multiple listings quoting Cambro's published specs
CenPro’s 5-gallon insulated dispenser is a direct, NSF-certified budget alternative built the same way, if Cambro’s price feels high for a first unit.
Premix agitated: when the drink is already mixed
A straight gravity spigot lets settled coffee solids or dairy separate over a shift. An agitated dispenser prevents that, but only for a finished drink, not raw concentrate diluted to order.
Refrigerated premix dispenser with agitation
Crathco (Grindmaster-Cecilware) Classic Bubbler (D25-4)
- Bowls
- Two 5-gal bowls, high-impact plastic with measuring marks
- Refrigerated holding
- 35 to 41°F
- Certification
- cULus and NSF certified
A gravity spigot has no answer for a premixed cold brew and milk drink separating mid-shift; the built-in agitators here do. The catch is it only works for drinks already mixed to final strength, and the dairy-adjacent bowls need daily teardown cleaning, more labor than a straight BIB-to-tap setup.

Cleaning cadence, and how long the concentrate lasts
Coffee and dairy residue in dispensing lines is a bacterial-growth risk, not just an aesthetic issue. Commercial-dispenser practice: daily wipe-down of surfaces and valves, a daily hot-water flush, and a short sanitizer soak on nozzles; weekly disconnect-and-soak of line connectors; monthly checks on ice bins and filters. NSF/ANSI-18 certification requires written clean-in-place instructions for exactly this reason.
Shelf life belongs to the concentrate, not the dispenser; none of the units above are concentrate products themselves. House-brewed concentrate commonly holds roughly 7 to 14 days refrigerated, with quality declining before it visibly spoils. Shelf-stable commercial BIB product can carry a longer stated shelf life, but the figure varies by brand and whether the box has opened, so check the printed date code rather than a generic number. Concentrate is not shelf-stable at room temperature.
Matching the mechanism to your cafe
Cold formats (cold brew, nitro, blended drinks) rose from 12% of adults reporting past-week consumption in 2020 to 17% in 2025, per National Coffee Association data, a demand signal, not a hardware-sales figure. If you’re low volume and a barista’s already diluting each cup, stick with gravity. Rising volume or a self-serve line changes the math toward a BIB proportioner. Need a pour that won’t sag by hour six? That’s a keg tap’s whole job. And if what you’re serving is already mixed to final strength at real volume, that’s the agitated dispenser. Check the certification on the specific SKU rather than assuming NSF tells the whole story, and build cleaning cadence into your checklist from day one.
For the brewing side, see the commercial cold brew maker guide; for nitro, the nitro cold brew tap guide goes deeper. Pair this with the coffee shop equipment list, the commercial coffee brewers guide for hot drinks, and the undercounter refrigerator guide for cold storage ahead of the dispenser.
Common questions
Do I need a BIB proportioner, or can a pitcher and a gravity dispenser work?
It depends on volume and how much you care about a consistent ratio. A pitcher and a gravity insulated dispenser is genuinely fine for a cafe pouring cold brew a few dozen times a day where a barista already dilutes to taste. A BIB proportioner earns its cost once 'eyeball the ratio every pour' becomes a real consistency or labor problem, or once you want self-serve or drive-thru service with nobody diluting per cup. Neither option is objectively better; it is a volume and workflow call.
What is the difference between NSF-7 and NSF/ANSI-18 on these dispensers, and does it matter?
Yes, and it is the detail most product listings in this category blur. NSF/ANSI 7 certifies the refrigerated cabinet, the box that keeps things cold. NSF/ANSI 18 certifies the dispensing equipment itself, the valve or spout that touches your drink. A cabinet-only NSF-7 rating does not mean the tap mechanism carries a separate dispensing certification. If health-inspector documentation matters to you, check which standard is printed on the specific SKU rather than assuming any 'NSF' label covers the whole machine.
How long does cold brew concentrate last once it is loaded into the dispenser?
That is a property of the concentrate's own packaging and manufacturer, not the dispenser holding it. Shelf-stable commercial bag-in-box concentrate is typically formulated for a longer refrigerated shelf life than concentrate brewed in-house yesterday, but the exact number varies by brand and by whether the box has been opened. Check the printed date code on your specific box rather than relying on a generic figure. What does not vary: concentrate is not shelf-stable at room temperature, opened or not.
Can cold brew concentrate run through a soda-fountain BIB pump already used for syrups?
No source confirms or rules this out across the board, so treat it as a question for your equipment supplier rather than an assumption. Coffee concentrate has different viscosity and particulate content than syrup, and BIB connector types are not universal across brands. Check your concentrate's specific BIB connector type against the pump's fitting with your supplier before assuming compatibility.
