If you love cold brew coffee then you may have heard of Nitro Cold Brew Coffee. This method takes the standard cold brew to the next level by infusing nitrogen throughout it and giving it an intense, foamy, cascading effect similar to how bars serve stout.
The benefit of nitro cold brew is that it gives a thick, creamy coffee without you needing to add creamer, sugar, or sweeteners. This result is a much more health-conscious and deliciously thick cup of joe.
This brings us to nitro cold brew coffee makers that you can use at home. These devices will save you loads of money over the years as instead of having to pop into coffee shops to enjoy the delicious brew you can simply make it at home for a fraction of the cost.
There are a few models out there and although they all do a similar job, there are some key differences that may make a particular one more suitable for your home or office.

Brand: Growler Werks
- Double Wall Vacuum Insulation

The uKeg Nitro has stolen our top spot today for several good reasons. The first reason is the double-wall insulation which keeps the cold brew coffee lovely and chilly without having to keep it in the fridge at all times. This is perfect for a summer BBQ or if you just like having coffee on tap at your work station.
The second reason I love this uKeg is that it’s designed so you can make your cold brew coffee using it rather than needing a separate device to do this. It comes with coffee bags and a funnel which makes this a really simple process.
It has a double filtration system that stops it from getting clogged up and a very well designed dispenser that uses nitrotap technology to give a cascading pour.
Brew your cold coffee overnight and then the next day you remove the coffee bags and add some fresh water to top it up. Next, add your nitro capsules to the cap and secure them in place. Shake the uKeg for 1-2 minutes (this is easy to do thanks to the handle) and serve the delicious Nitro cold brew coffee straight into a glass!
It’s super simple to use and the all-in-one design makes this one of the best nitro coffee makers to give you coffee shop quality, foamy iced coffee from the comfort of your own home.
2. Runner Up – Royal Brew Nitro Cold Brew Coffee Maker
Brand: Royal Brew
- Tap Plug Plus Carry Bag
- 64 Ounce Keg

Next up, we have this clever little model by Royal Brew. I love the classic keg design with its clean, stainless steel finish and it even comes with a handy carry bag. To help keep those countertops clean, the tap plug catches all those pesky drips which help to make this a clean kitchen companion.
You do need to brew your coffee separately, but once it’s ready you simply add it to the keg. The dispenser screws in place and then all you need to do is add two nitrogen (N2) or a single nitrous oxide (N2O) canister. Shake the keg well for 15-20 seconds and let it sit for half an hour. You can then add the second cartridge and place the keg in the fridge for an hour.
The manufacturers have included bonus o-rings which help give a perfect seal and avoids nitro gas leakage. This little extra helps make this cold brew system clean and efficient to use as well as giving you beautiful velvety, frothy iced coffee again and again.
As a nice bonus, this option comes with a lifetime warranty for peace of mind.

4. Best Multi-Use Option – Bubblingplus Nitro Cold Brew Coffee Maker
Brand: Bubbling Plus

If speed and versatility are what you’re after then consider this option by Bubbling Plus. The slow-flow tube design that utilizes food-grade silicone, allows thorough mixing of gasses and fluid without any shaking needed from you.

5. Large Capacity Option – VBENLEM Nitro Brew Coffee Maker
- 2 and 5 Litre Options Available
- Classic Keg Design
- Stainless Steel
If you live in a home or work in an office that has many nitro brewed coffee lovers, then you need a device that’s up to the task. This Vbenlem option has a 2 liter and a 5 liter option. It’s a hefty option, with thickened 304 food-grade stainless steel which is easy to clean and very durable.
One feature I really like is that you can remove the tap head attachment and screw the stopper in here to allow you to easily store your drinks to keep them fresh.
It’s an attractive, mini-keg design and has carry handles for easy transport.
This is a good option if you’re looking to make larger amounts of nitro brew but it’s worth noting, as will all nitro brew makers, never fill them up more than halfway with coffee. You need to leave space for the nitrogen to infuse so the 5-liter keg will manage 2.5 liters of coffee each time.
What To Consider When Choosing A Nitro Cold Brew Coffee Maker
The internal capacity of your nitro brew coffee machine has to suit your needs. It can take anywhere between 1 hour to 12 hours for the coffee and nitrogen to fully combine so you typically can’t quickly whip up a second batch.
It’s also important to note that the volume the keg can hold isn’t how much coffee it can take on. To allow the coffee to expand with the gas added you can usually only fill these machines to 50% capacity (some will hold as much as 75%). Make sure you half the capacity that’s been stated to ensure that is enough coffee to satisfy you.
The type of charger needed to infuse the gas into your coffee needs to be considered. You want a machine that can handle nitrogen chargers (N2) to give that cascading foam effect and not just nitrous oxide (N2O) like a whipped cream dispenser.
Chargers are usually always sold separately and come in different weights and sizes. Some kegs will require two chargers per batch of nitro brew so make sure you order plenty of the correct ones so you can use your coffee machine when it arrives.
Stainless steel is the typical material used to make nitro brew canisters. It’s durable, corrosion-resistant, and very easy to keep clean.
Some models will use silicone and plastic for the taps and pipework. Where these are used it’s best to check the materials are BPA free to ensure and safe and healthy brew.
The external dimensions of your nitro brew machine is another consideration. Most of these models require that it sit in the fridge for an hour or longer. You need to make sure you have enough room to accommodate the model you choose in your home or office fridge.
Some of these coffee makers serve a dual purpose which can be useful if you like other beverages besides coffee. Some will dispense craft beer or stout. Some will aerate wine before you serve it. Some will even take CO2 chargers to make carbonated beverages like sparkling water. If you like to get creative in the kitchen or fancy yourself as more of a bartender than a barista then consider a multi-use option like the Bubbling Plus model.
How To Make Cold Brew Coffee
You can buy cold brew coffee ready to add to your nitro coffee maker but if you enjoy the simple satisfaction of brewing coffee at home then you may like to try making your own cold brew coffee.
Cold brew coffee is a slow extraction process where ground coffee is steeped in cold water for around 12 hours to give a smooth, mellow, sweet cup of coffee that’s lower in acidity compared to regular coffee.
To make your own cold brew at home you need some coffee beans (or ground coffee ideally that’s labeled for cold brew), a grinder, a jar or pitcher, and some means to filter out the coffee grounds. This can be a specially bought cold brew coffee maker, coffee bag, french press, tea strainer, or anything similar.
You want to grind the coffee on a very coarse setting and add this to the jug or jar at a 1:7 ratio to cold water. You can adjust this ratio to suit your own taste preferences. It’s a good idea to use filtered water to get the best results.
Let the grounds steep in cold water in the fridge overnight or for around 12-14 hours. Once it’s fully brewed you can pass the whole lot through a coffee filter or remove the coffee bag if using.
This will leave you with a lovely dark, cold brew concentrate that you can drink as is or dilute to suit your tastes.
This can be added as is to your nitro brewer or you can mix some creamer or cold water with it before you add it. Have a play around with different ratios and coffee types until you get a batch that suits you perfectly.
Can I add creamer to the nitro brew coffee maker?
Adding creamer or milk to your cold brew before you add it to the nitro brew maker is a good idea to enhance the creaminess of the end product. Coffee shops will sometimes do this to get the thickest, foamiest results and this may account for differences in the taste of your homemade nitro coffee.
Why does my nitro brew coffee maker drip?
The pressure that builds up in your nitro brew coffee maker that causes that beautiful cascading effect unfortunately also causes some leakage of the faucet after you pour the coffee. A pressure relief valve or can minimize this and a tap plug can stop this issue.
It’s best to place a drip tray under the faucet after pouring or when it’s left with the tap attached to catch any mess.
Is Nitro cold brew bad for your health?
Where it comes to nutrient content and health benefits/risks nitro brew coffee is very similar to regular coffee. You’ll still benefit from the longevity and weight loss aids that hot coffee provides.
What is so special about Nitro cold brew?
Nitro cold brew coffee has been infused with nitrogen gas to give a microfoam texture. All the tiny air bubbles give the coffee a thick, foamy mouthfeel and Nitro cold brew tastes sweeter and is less acidic.
