The Original Royal Brew Nitro Cold Brew Coffee Maker – 128 Oz

Best for large offices or events that require a high-capacity nitro system. This extra-large 128 oz keg supports batch serving for gatherings, parties, or teams that want café-style nitro coffee readily available without frequent refills. It creates a smooth cascading nitro effect, delivering an appealing texture that mimics professional setups. Cartridges for nitrogen (N₂) or nitrous oxide (N₂O) are compatible, though cartridges are sold separately. Caution: The larger keg may take more fridge or counter space; ensure adequate storage.
Royal Brew Nitro Cold Brew Coffee Maker, 64 oz Black

Best for mid-sized offices that want a reliable, compact nitro system with a stout creamer faucet. The 64 oz stainless steel keg holds around four pints and fits standard refrigeration. It accepts nitrogen (N₂) cartridges for a cascading texture or nitrous oxide (N₂O) cartridges for a creamier mouthfeel. Note that cartridges are sold separately. Choose this if you prefer a balanced footprint with café-style nitro at the ready.

This 128 oz keg mirrors the large-capacity profile for office scenarios that require extended service without frequent refills. It supports nitrogen or nitrous cartridges to achieve the classic nitro cascade or a creamier finish. Clear best-use case: offices hosting longer meetings, training sessions, or frequent tastings where multiple servings are desirable without interruptions. Caution: Ensure your office has adequate CO₂-free gas options and proper cartridge compatibility.
NITRO Cold Brew Coffee, Organic Guatemala, Keg 5 Gal

Best for offices seeking maximum volume per keg with long shelf stability. This Bona Fide craft system uses a 5-gallon keg with nitrogen gas-exclusive dispensing. It’s well-suited for breakrooms or shared kitchens that require large batches of nitro coffee or other cold brews. Important: PET kegs require pure nitrogen (N₂); CO₂ should not be used. Consider this option for high-demand environments where storage and long shelf life matter.
Nitro Cold Brew Keg, 64oz Stainless Steel Mini Keg

Best for smaller offices or breakout areas that still want café-quality nitro coffee on tap. This 64 oz stainless steel mini keg includes a dedicated gas port for fast nitrogen infusion, offering a compact, durable solution. It’s compatible with nitrogen or nitrous oxide depending on your flavor goals, though 2g cartridges are common. Limitation: Cartridges are not included; plan for ongoing cartridge purchases and ensure fridge space accommodates the device.
GrowlerWerks uKeg Nitro Cold Brew Coffee Maker, 50 oz

Best for desks and small break areas where space is at a premium. The 50 oz uKeg is compact, portable, and designed for easy home or office use. It requires 16 g nitro chargers (sold separately). Choose this if you need personal- or small-team servings without committing to larger keg systems. Limitation: Smaller capacity means more frequent refills for higher demand environments.
Buying Guide: Key Considerations For Office Cold Brew Kegs
Capacity and serving schedule: Larger kegs reduce refills but require more storage. For busy offices, plan for at least 64 oz per serving cycle and ensure your fridge or prep area can hold multiple units if needed.
Gas cartridge options: Decide between nitrogen (N₂) for cascading nitro texture or nitrous oxide (N₂O) for a creamier head. Some models support both, but cartridges are usually sold separately. Confirm cartridge compatibility before purchase.
Material and durability: Stainless steel kegs offer durability and temperature stability, while PET kegs are lighter but may require careful handling. Consider your office climate and cleaning routines when selecting material.
Space and portability: Offices with limited counter space benefit from compact, portable units that fit inside standard refrigerators or breakroom cabinets. Larger kegs require more dedicated storage.
Maintenance and cleaning: Look for kegs that are easy to disassemble for cleaning and reusing. A quick daily rinse and complete wash weekly can help maintain flavor quality and system hygiene.
Cost of ownership: Beyond the initial price, factor in cartridge costs and potential replacement parts. A higher-capacity system can lower per-cup costs in high-demand offices, while a smaller unit reduces upfront investment.
