A cold brew keg can make an office coffee setup easier to share, but the right choice depends on how much your team drinks and whether you want a compact countertop dispenser or a keg that connects to a draft system. These picks range from small nitro coffee makers to a five-gallon ball-lock keg. For most offices looking for a straightforward setup, a 64-ounce model is a practical place to start; larger teams may prefer more capacity.

Our Picks: Best Cold Brew Keg For Office reviews
Royal Brew 64 oz Nitro Cold Brew Maker: Best All-Around Office Size
The Royal Brew 64-ounce keg is a compact nitro coffee maker designed for serving cold brew through a stout faucet. Its stainless steel body holds up to four pints, giving a small team a shared supply without stepping up to a full-size draft keg.
To use it, fill the keg with prepared cold brew, add a compatible cartridge, shake, and refrigerate. It supports food-grade 2-gram nitrogen cartridges for a cascading nitro texture or an 8-gram nitrous oxide cartridge for creamier foam. The cartridges are sold separately, so factor in the extra supplies and make sure the office is comfortable handling them.
This model stands out as a balanced option when fridge space and simple serving matter more than a large batch. It includes tubing, a cartridge holder, a wrench, and a cleaning brush. Its main limitation is capacity: a busy team may empty it quickly, and it still needs room in the refrigerator while filled.
Pros:
- Compact 64-ounce capacity fits smaller office routines.
- Stainless steel keg with a stout faucet for draft-style pouring.
- Supports both nitrogen and nitrous oxide cartridges.
- Includes several setup and cleaning accessories.
Cons:
- Cartridges must be purchased separately.
- Smaller capacity may mean frequent refills in a busy office.
Verdict: Choose this Royal Brew if you want a relatively compact nitro keg with a clear, simple brew-to-pour process and your office can manage a four-pint supply.
VEVOR 68 oz Nitro Cold Brew Maker: Best for Portable Serving
With a 68-ounce capacity, the VEVOR offers a little more volume than the two 64-ounce countertop choices. It is a portable, no-power dispenser made with a 304 stainless steel tank, and its self-closing faucet is designed to reduce drips during serving.
The listed process is straightforward: add the beverage, insert a nitrogen charger, shake, and dispense. The system is described for cold brew as well as beer, tea, milk, and other drinks. Its vacuum-sealed construction and pressure-relief valve are intended to help preserve pressure; the product description says refrigerated contents can stay fresh for up to two weeks. Treat that as a product claim and follow safe food-storage practices for your prepared brew.
This keg could suit an office that wants one dispenser for more than coffee or needs to move it between a refrigerator and serving area. The listing does not specify cartridge size or the exact cartridge setup, so check compatibility before ordering supplies. As with the other smaller kegs, a 68-ounce capacity may not be enough for a large group between refills.
Pros:
- 68-ounce capacity is slightly larger than a 64-ounce keg.
- Does not need power to dispense.
- Self-closing faucet is designed to reduce drips.
- Listed for use with several chilled beverages, not just coffee.
Cons:
- Cartridge size and compatibility should be confirmed before purchase.
- Still requires refrigerator space and regular refilling for larger teams.
Verdict: Consider the VEVOR if portability and multi-drink use are priorities, but verify the cartridge requirements to avoid a supply mismatch.
MRbrew 5-Gallon Ball Lock Keg: Best for a Draft-System Office
The MRbrew is a very different kind of option from the countertop nitro makers. This five-gallon Cornelius-style keg is built for a compatible ball-lock draft setup. It is made from food-grade 304 stainless steel and has separate gas and liquid posts for connecting standard ball-lock fittings.
The listed kit includes two quick-disconnect fittings and an eight-piece gasket set. Those parts can help with connecting and maintaining the keg, but the product description does not list a complete kegerator or gas supply. Plan on using a compatible draft system and confirm that your existing equipment fits the keg’s connections.
Its larger capacity makes it more suitable for a busy workplace, coffee bar, or shared serving area than a small office kitchenette. That volume also brings practical trade-offs: the filled keg is much less portable than a 64-ounce dispenser and requires a suitable place to store and serve it. Measure the intended space and check your draft setup before buying.
Pros:
- Five-gallon capacity can serve a larger group with fewer refills.
- 304 stainless steel construction and replaceable gasket set.
- Includes gas and liquid ball-lock fittings.
- Designed for cold brew and other beverages in compatible draft systems.
Cons:
- Requires a compatible draft setup; it is not a self-contained countertop nitro maker.
- Its size and filled weight make storage and moving more demanding.
Verdict: Pick the MRbrew if your office already has suitable ball-lock draft equipment and needs a high-capacity keg; skip it if you want an all-in-one dispenser.
Zulay Nitro Cold Brew Maker: Best for a Tidier Countertop Pour
The Zulay is a 64-ounce stainless steel nitro keg with a creamer faucet. It is designed to serve prepared cold brew, and the listing also describes using it with chilled drinks such as tea and lemonade. The keg has a pressure-relief valve and a black powder-coated finish.
Its listed accessories are useful for a shared counter: a faucet cap, silicone mat, and collapsible funnel are intended to help contain drips during storage and filling. The maker supports one 8-gram non-thread nitrous oxide cartridge or two non-thread 2-gram nitrogen cartridges, which are not included. The instructions call for filling the keg to 75% of its capacity to leave room for gas.
The capacity is in line with the Royal Brew 64-ounce model, but the Zulay puts extra emphasis on spill control and its included funnel and mat. The listing describes refrigerated freshness for up to two weeks; as with any prepared beverage, follow appropriate storage practices. Availability can vary, so check the listing before choosing it for an office purchase.
Pros:
- 64-ounce stainless steel keg with a creamer faucet.
- Includes a funnel, silicone mat, and faucet cap to help manage spills.
- Lists both nitrogen and nitrous oxide cartridge options.
- Can be used for several chilled drinks in addition to cold brew.
Cons:
- Cartridges are not included and must match the specified non-thread type.
- Capacity may be limited for a high-traffic office.
Verdict: Choose the Zulay if its included spill-control accessories fit your shared coffee area and you are comfortable sourcing the correct cartridges separately.
Royal Brew 128 oz Nitro Keg: Best for Fewer Refills
This extra-large Royal Brew keg holds 128 ounces, twice the listed capacity of the 64-ounce Royal Brew model. That added volume can reduce how often someone needs to refill it, making it a better fit for a team that shares cold brew throughout the day.
The product description says to fill the keg no more than 75% with coffee to leave room for gas, then charge and shake it. It lists two 8-gram nitrous oxide cartridges for a sweeter, creamier foam or four 2-gram nitrogen cartridges for a cascading texture; cartridges are sold separately. The keg is described as fitting in a fridge, but its stated dimensions—17.5 inches tall and 7.5 inches across the faucet and keg—make measuring your refrigerator especially important.
The 128-ounce size offers more capacity than the small countertop choices, but it also takes up more space and holds more prepared coffee than some offices will use quickly. Choose it based on your team’s expected consumption and fridge layout, not capacity alone. The listed dimensions and cartridge needs are worth checking before committing.
Pros:
- 128-ounce capacity means fewer refills than a 64-ounce keg.
- Offers both nitrogen and nitrous oxide cartridge options.
- Designed to be stored in a refrigerator for serving chilled coffee.
- Useful for a larger shared coffee setup.
Cons:
- Larger footprint may be difficult to fit in a crowded office refrigerator.
- Requires multiple cartridges per charge, which are sold separately.
Verdict: Choose the 128-ounce Royal Brew if your office goes through cold brew quickly and has measured enough refrigerator space for the taller, wider keg.
How to Choose a Cold Brew Keg for Your Office
Match capacity to your team’s daily use
A 64- or 68-ounce keg is a manageable starting size for a small team or a shared coffee station with moderate use. Larger offices may prefer the 128-ounce Royal Brew to reduce refills. The MRbrew holds five gallons, but that size makes the most sense when you have a compatible draft setup and a clear plan for storing and serving a much larger batch.
Decide between a countertop keg and a draft keg
Countertop nitro makers are designed to hold prepared cold brew, take a cartridge, and pour from an attached faucet. A ball-lock keg, such as the MRbrew, connects to compatible draft equipment instead. If your office does not already have that equipment, include the space and setup needs in your decision rather than assuming the keg alone is ready to serve.
Check cartridge type and ongoing supplies
Cartridge compatibility is not the same across these products. The Royal Brew 64-ounce model lists 2-gram nitrogen and 8-gram nitrous oxide options; the Zulay specifies non-thread cartridges; and the 128-ounce Royal Brew lists multiple cartridges per charge. The VEVOR listing calls for nitrogen but does not specify the cartridge size in the provided details. Confirm the correct type before ordering, and remember that cartridges are sold separately where stated.
Measure the refrigerator and serving area
Cold brew kegs need a suitable place to stay chilled, and the larger models can take up more room than their capacity alone suggests. Measure refrigerator height, shelf depth, and the space needed to operate the faucet. For the 128-ounce Royal Brew, the stated height is 17.5 inches, with a 7.5-inch span across the faucet and keg. Also consider where people will pour and whether the area is easy to clean.
Consider cleanup and drip control
A shared office dispenser should be simple to clean and unlikely to leave sticky coffee around the counter. The Royal Brew 64-ounce model includes a cleaning brush, while the Zulay includes a funnel, mat, and faucet cap. The VEVOR describes stainless steel parts and a self-closing faucet designed to reduce drips. Check which accessories matter most for your setup and plan a regular cleaning routine.
Think about serving style and drink options
Nitrogen and nitrous oxide can produce different textures, and some models list both options. Decide whether the office wants a more cascading nitro pour or a creamier foam, then confirm that the chosen keg supports the cartridge you want. If coworkers may use the dispenser for tea or other chilled beverages, verify that use in the product description and clean the keg between different drinks.
Frequently Asked Questions
What size cold brew keg works well for an office?
A 64- or 68-ounce keg can suit a small team or a coffee station with moderate use. For a larger group, a 128-ounce model can mean fewer refills. A five-gallon keg offers much more capacity but needs a compatible draft setup and suitable storage space.
Do these cold brew kegs include cartridges?
The Royal Brew 64-ounce and 128-ounce descriptions say cartridges are sold separately, and the Zulay says its cartridges are not included. Check the VEVOR listing for its cartridge requirements and included supplies before ordering.
What is the difference between nitrogen and nitrous oxide in these makers?
The product descriptions associate nitrogen with a smooth, cascading nitro texture and nitrous oxide with creamier or sweeter foam. Cartridge type and size vary by keg, so follow the specific maker’s compatibility instructions.
Can I use a five-gallon ball-lock keg without a kegerator?
The MRbrew is designed to connect to a compatible ball-lock draft setup. Its listed contents include fittings and gaskets, but not a complete kegerator or gas supply. Confirm that your equipment is compatible before buying.
Do office cold brew kegs need electricity?
The VEVOR description says its dispenser does not need power. The countertop cartridge models are also described with a manual fill, charge, shake, and pour process. A separate draft setup for a ball-lock keg may involve additional equipment, so check the requirements for the system you plan to use.
How much should I fill a nitro keg?
Follow the instructions for the specific model. The Zulay and 128-ounce Royal Brew descriptions say to leave room for gas by filling no more than 75% of the keg. Do not assume every keg uses the same fill level.
Which pick is the best starting point for most offices?
The Royal Brew 64-ounce model is a practical starting point for a small or moderate-use office because it combines a compact capacity with a stout faucet and listed cartridge options. Choose a larger keg if your team’s consumption or existing draft setup calls for more volume.
Final Recommendation
For most offices that want a compact, cartridge-powered nitro coffee keg, the Royal Brew 64-ounce model offers a useful balance of capacity and included setup tools. The VEVOR is worth considering if portability and multi-drink use matter, while the Royal Brew 128-ounce keg suits teams that need more coffee between refills. Choose the MRbrew only if you have compatible draft equipment, and measure your refrigerator before selecting any of the larger options.
