1. A 64 oz stainless steel keg holds up to 4 pints of finished nitro cold brew, enough for several days of pours from one batch.
2. Compatible with both 2g nitrogen (N2) cartridges for a classic cascading pour and 8g nitrous oxide (N2O) cartridges for a sweeter, creamier foam, letting buyers tune texture and flavor.
3. The stout creamer faucet is built to recreate the cascading nitro pour associated with draft coffee taps, not just carbonate the drink.
4. A reusable filter and manual operation keep things simple - the keg only stores and dispenses cold brew you've already made.
5. The included kit ships with tubing, a cartridge holder, faucet wrench, tap plug, carry bag and cleaning brushes, aimed at making setup and cleanup a self-contained job.
6. Compact dimensions of 7 in D x 5 in W x 10.87 in H are sized to fit inside a refrigerator, though it can be a little hard to fit and measuring first is advised.

How we score

We score each thing that comes up most in owner feedback on the Royal Brew Nitro Cold Brew Coffee. Seven things come up most in owner feedback: five draw praise, one splits opinion and one draws mostly complaints. Its ratings average 4.3 stars (69% five stars, 14% four, 5% three and 12% one or two), so every score starts at 86, that average on a 100 point scale. Where opinion is split, we take off 6. Where it draws mostly complaints, we take off 12. Then we read eight owner reviews in full, including the critical ones, and move the score up to 5 points either way depending on how the owners who mention it rated the product. Our overall score starts from the same 4.3 star average and loses 0.1 for each thing that draws mostly complaints, with 0.1 more when at least a tenth of ratings are one star, never more than 0.3 in all. Here that takes off 0.1, which gives 4.2. Read our editorial standards

Ease of use, value against café prices, and the taste and texture of the finished pour draw consistent praise, with several buyers rating the result on par with shop-bought nitro cold brew once they've dialed in their own concentrate recipe. Cleaning is generally described as straightforward, particularly with hot water rinses. Opinion splits sharply on the printed instructions, which some call clear enough once paired with the brand's videos and others call poor, contradictory or missing steps. The most serious complaint is leakage; a nitrogen fitting or the pressure-relief valve can fail, in some cases on only the second use or after a few months.

1. Brew a strong concentrate first

   Prepare cold brew concentrate separately, using coarse grounds steeped roughly 24 hours, then strain it thoroughly - even a small amount of silt or grit will spoil the mouthfeel once nitrogen is added. Off-the-shelf cold brew can taste almost like water once nitrogenated, so a slightly diluted concentrate is recommended instead.

2. Fill the keg to the recommended line

   Fill the 64 oz keg to about 75% capacity (roughly 48 oz) rather than to the top, leaving headspace for the nitrogen cartridge to pressurize the liquid. Since there's no viewing window on the tank, measuring the concentrate in a separate container before pouring it in avoids under- or overfilling by guesswork.

3. Assemble the faucet and check gaskets

   Attach the stout creamer faucet and confirm every gasket is seated; installing an additional provided gasket can help, though the gasket mentioned in the instructions is not always included in the package. Leaks are a reported issue, so it's worth checking the gaskets before the first charge rather than after.

4. Charge with nitrogen and shake

   Insert one 2g N2 cartridge (or an 8g N2O cartridge for a sweeter result), remove it promptly, then shake the keg vigorously for about 30 seconds. Adding a second N2 cartridge after a short rest can give a café-like result; N2O needs only one cartridge but later glasses may have much less gas.

5. Refrigerate before pouring

   Let the charged keg rest in the fridge for about an hour before the first pour. Adding a pressurized cartridge can warm the coffee even when it started cold, so this rest lets it chill back down before pouring.
