Ever wondered why nitro cold brew looks like a stout, tastes naturally sweet, and kicks harder than your average iced coffee?

This cold coffee trend didn’t just survive—it exploded. From hip cafés to Starbucks to your local grocery aisle, nitro cold brew is everywhere.

I’ve brewed it, tested it, and even built my own DIY nitro setup to see what really makes this drink different—from taste and caffeine to how it’s made!

Quick Answer: What is nitro cold brew coffee?

Nitro cold brew is cold-brewed coffee infused with nitrogen gas to create a smooth, creamy texture and foamy head. The nitrogen reduces acidity, enhances sweetness, and mimics the mouthfeel of stout beers.

It contains more caffeine than standard coffee and is available in cafés, cans, or homemade.

Nitro cold brew: Key points

  • Made from: Cold brew + nitrogen infusion
  • Tastes like: Creamy, sweet, low-acid coffee
  • Caffeine level: Often higher than iced or hot coffee
  • Looks like: A Guinness-style beer with a foamy top
  • Best for: Anyone wanting smooth, bold coffee without bitterness

What Is Nitro Cold Brew? Taste, Benefits & How to Make It

What is nitro cold brew?

Nitro cold brew is cold brew coffee infused with nitrogen gas, giving it a creamy texture and smooth flavor with extra caffeine.

This process preserves the flavor and freshness of the beans. As a result, the drink has more caffeine but less acidity than other coffees and a creamier and sweeter taste.

Nitrogen-infused coffee offers a smoother texture than sodas and other carbonated beverages because nitrogen bubbles are smaller than carbon dioxide bubbles. Coffee houses sometimes serve nitro coffee on tap.

Additionally, canned nitro cold brew can be found at grocery stores, and you may brew your nitro coffee at home.

People often compare the appearance of nitro coffee to a Guinness beer because of the similarities in their appearance.

In truth, nitro cold brew was most inspired by bartenders’ practice of infusing dark beers such as stouts, ales, and lagers with nitrogen gas rather than carbon dioxide.

There is a dispute over who initially created nitro coffee. It might have been Mike McKim in Austin, Texas, or Nate Armbrust in Portland, Oregon.

But, if you dig a little deeper, a third person, Lorenzo Perkins, also in Austin, Texas, claims to be the first person to serve it publicly.

Why pure nitrogen is used in nitro coffee

Pure nitrogen is essential as it makes the coffee sweeter. The early developers of nitro coffee realized that carbonated cold coffee needed pure nitrogen.

They tried using the 75/25 nitrogen and carbon dioxide mix used to make tap micro beers and Guinness, but this mixture resulted in bitter coffee.

The problem with using carbon dioxide is that it leaves a bitter taste as it dissolves. Flat sparkling water tastes acidic because of this.

So, after much experimentation, developers realized that pure nitrogen would dissolve slowly and give the perception of a creamier drink.

Therefore, if you try to make nitro at home with carbon dioxide chargers, the results will be bitter.

What is the difference between iced coffee, cold brew, and nitro coffee?

What makes nitro cold brew different from other iced coffee drinks?

Here’s a quick overview to see the difference between these three coffees:

Coffee TypeBrew MethodServed With Ice?Nitrogen Infused?Flavor ProfileAcidityCaffeine Content
Iced CoffeeBrewed hot, then cooledYesNoBrighter, sometimes more bitter flavor compared to cold brewHigherModerate
Cold BrewSteeped in cold water for 12–24 hoursYesNoSmoother, mellower flavor with chocolatey notesLowerHigh
Nitro Cold BrewCold brew infused with nitrogenNoYesCreamy, naturally sweet flavor with a velvety textureLowerHigh

Let’s go more in-depth now!

To start: Iced coffee and cold brew.

Iced coffee is hot coffee cooled down, usually with ice cubes, while cold brew coffee is never heated.

Nitro coffee is nitrogen-infused cold-brewed coffee. Iced coffee and cold brew coffee might need sweeteners, but nitro cold brew is naturally sweeter.

Iced coffee is fast and easy to make. First, you brew coffee and pour ice over it.

If you plan to make a large batch to refrigerate, add more coffee grounds when you brew it.

So why not use iced coffee and infuse it with nitrogen to make nitro coffee?

The answer is chemistry. Researchers analyzed hot and cold-brewed coffee for both antioxidant and acidity levels.

They found that the levels of caffeine were similar and that hot coffee extracted more antioxidants while brewing. (Source)

Although antioxidants are healthy, they also don’t impart much flavor. However, acidity does, and the cold brew has less acidity.

Cold or iced coffee tends to be acidic, which any coffee drinker knows when heating up day-old coffee.

So, if you make nitro at home with iced coffee, expect it to be bitter.

Summary: While all three beverages are served cold, their flavor profiles differ significantly due to their brewing methods and any additional processes, such as nitrogen infusion.

Iced coffee offers a brighter and more acidic taste, cold brew provides a smoother and less acidic experience with chocolatey notes, and nitro cold brew delivers a creamy, naturally sweet flavor with a velvety texture.

Nitro cold brew caffeine content compared to regular coffee

Nitro cold brew contains more caffeine than hot coffee. Several factors, such as the temperature used when brewing the coffee, the length of brewing time, and the type of beans used to make the drink, can all play a role in determining the caffeine content.

It is difficult to make a direct comparison between the two because the quantity of coffee and how it is made affect the caffeine content.

Based on information from Medical News Today, these are typical caffeine levels in coffee beverages:

Coffee typePortion sizeAmount of caffeine
Hot brewed8-oz (226 ml)95 mg (0.003 oz)
Decaf (Yes, it has some caffeine)8-oz (226 ml)2 mg
Cold brew12-oz (340 ml)153 mg to 238 mg (0.005 to 0.008 oz)
Instant8-oz (226 ml)63 mg (0.002 oz)
Espresso1-oz (28 ml)63 mg (0.002 oz)

It’s difficult to compare nitro coffee directly because caffeine content depends on brew method, portion size, and bean type.

A direct comparison between the coffees in the following chart is based on Starbucks’ standard 12-oz cups.

These are caffeine levels for 12 oz (340 ml) of several Starbucks coffees:

DrinkCaffeine Level
Cold brew150 mg (0.005 oz)
Reserve nitro280 mg (0.009 oz)
Regular nitro215 mg (0.007 oz)
Brewed pike place blend235 mg (0.008 oz)
Brewed blonde roast270 mg (0.009 oz)

Even within one brand, caffeine levels vary greatly, depending on how the drink is produced and the roast level of the coffee.

So, nitro brew generally has more caffeine, but it’s possible to find hot brewed coffee with similar caffeine levels to its nitro counterparts.

Again, it’s all about the roast and brewing process!

How is nitro cold brew made?

Nitro cold brew is made using a two-step process:

  1. Create a cold brew
  2. Add nitrogen gas

The good news is that making nitro coffee at home is not as complicated as it seems. If you can make cold brew, you can make nitro after purchasing a few pieces of equipment.

Coffee shops make their nitro by first preparing a cold brew and then pouring it into a metal keg.

The nitrogen gets infused with a specialized infuser that infuses the nitrogen into the cold brew.

The keg is then connected to a tap system, and the nitro coffee, with its signature texture and foam, can be poured into a glass.

It sounds simple, but the faucet, gas tanks, keg connectors, tubes, and hoses must be installed and maintained.

In addition, the baristas need to be trained to use the equipment. Adding nitro coffee to a menu can easily cost a coffee shop $1,500 to $2,000, which is why they have to charge a premium for the drink.

Many fans have begun making nitro cold coffee at home to save money.

How to make cold nitro cold brew at home (Step-by-step guide)

Wondering how to make nitro cold brew at home without a keg?

The easiest way to start is using a whipped cream dispenser and nitrous oxide cartridge—no expensive tap system is needed!

Here’s a six-step process that will get you drinking homemade nitro in no time:

  1. Grind the coffee beans to a medium-coarse consistency. If you purchase your coffee from a coffee shop, tell the barista the beans are for making a cold brew.
  2. Combine ⅓ cups (78.86 ml) of ground coffee with 1½ cups (354.88 ml) of cold or room-temperature water in an airtight container. If the container is not airtight, the coffee will oxidize and create an unpleasant flavor.
  3. Allow the mixture to steep. The water and coffee should sit at room temperature for 12 hours or be refrigerated for up to 24 hours.
  4. Strain the coffee using a fine-mesh strainer lined with cheesecloth, a nut milk bag, or a paper coffee filter. You can mix your cold-brew coffee concentrate with water (a 1:1 ratio is typical, but feel free to experiment). You may keep your cold brew in the jar for up to ten days.
  5. Mix 1 cup (236.59 ml) cold water with 1 cup (236.59 ml) concentrated cold brew into a whipped cream dispenser and seal it.
  6. Charge the cold brew with a nitrous oxide cartridge. Shake the drink roughly 10 times and let it sit until the container feels cold to the touch.
  7. Pour into a glass slowly, and enjoy! If you go too quickly, the nitro cold brew might look like the photo below for a bit. Wait for a bit and pour in more cold brew to fill the glass:

What are the best coffee beans for making nitro coffee?

The best coffee beans for nitro coffee are a lighter roast.

Cold-brewing coffee will affect the flavor profile, and you may discover that the flavor you love will get lost in the cold brewing process.

Although medium and dark roasts are usually recommended, how you grind the beans is essential. Incorrectly grinding the beans can ruin your favorite coffee.

In general, nitro and cold brew coffee reduce the coffee’s acidity level, so some people use a lighter roast to reduce the acidity, as lighter roasts are more acidic than dark roasts.

Dark roast coffee has rich flavor notes, such as chocolate, earthy, nutty, or even a little syrupy.

These notes will overpower the light floral notes of lighter roasts or single-origin varieties.

One other reason why people prefer dark roasts for nitro coffee is that the roasts are less expensive.

Single-origin varieties are more expensive, further adding to the extra expense of nitro coffee.

Just keep in mind that if you decide on a lighter roast, you’ll need to plan on a longer extraction time to obtain the flavor you’re after. Still, the best place to start experimenting is your favorite coffee.

If you start with a coffee that you know, you can better identify the changes in flavor.

What is the best grind size for nitro cold brew?

So, how fine should you grind your coffee beans for cold brew?

The best grind is a coarse grind for several reasons. For one thing, the coarse grind will start pouring the quickest.

However, a fine grind will be excessively dense, causing the water to flow too slowly.

As a result, water tends to collect above the bed of fine coffee grinds, leading to patches of unbrewed coffee.

Furthermore, fine grinds can sometimes have a harsh, bitter flavor due to over-extraction.

The water can easily flow through the beans and extract more of the flavors with a coarse grind:

Does nitro cold brew contain alcohol?

Although numerous factors contribute to this misperception, nitro cold brew does not have alcohol. Some people believe it includes alcohol because it is processed with nitrogen, the same component used in producing certain beers such as Guinness.

Nitro coffee has a similar mouthfeel to stouts like Guinness, and some beers have coffee tones in their flavor profile.

Another thing beer and nitrogen-infused coffee have in common is that both can be poured straight from a tap. But there is no alcohol in the nitro coffee.

Can you heat nitro cold brew coffee?

You can heat nitro coffee. The process starts with making a cold brew, then adding the nitrogen and storing it. When the coffee is heated, the nitrogen will reduce faster than cold nitro.

Hot nitro is a hard-to-find boutique coffee, and only a handful of coffee shops serve it.

Besides people’s reaction that it sounds like hot soda pop, the biggest hurdle is that hot nitro requires even more specialized machines that heat the coffee while maintaining the nitrogen level.

At least one company, NitroBrew, sells a kit for making hot or cold nitro drinks at home.

The kit includes a kettle, nitrogen charger, and air compressor. However, prepare yourself for sticker shock, as these kits are specialized and don’t benefit from mass production price reductions.

Why nitro cold brew is less acidic

Nitro enthusiasts claim there is less acid in nitro, but what could cause the acidity to be lower?

Is there a simple explanation, or do you need a chemistry background to understand terms like “deprotonated acid,” “radical scavenging capacity,” and “CQA isomer concentrations?” Not really.

Nitro has less acid because hot brew methods extract more acids from the beans. These acids could be responsible for the increased levels of antioxidants in hot coffee.

However, these deprotonated acids also remove more acid from the beans, which becomes part of the coffee you drink.

Since cold brew leaves more acid in the beans, it is less acidic.

Is nitro cold brew coffee healthy or harmful?

So, is nitro cold brew healthy for you?

Nitro coffee is only bad if you drink more caffeine than your body can handle.

And since nitro coffee brew generally has more caffeine, you want to regulate how much you drink.

Although there are some health benefits to antioxidant-rich coffees, the drink also comes with some risks.

  • Increased anxiety levels. Caffeine can affect your hormones, neurotransmitters, and mood. If you always use coffee because you are exhausted, you might need to find time to relax to recharge your batteries.
  • Caffeine overdose. Caffeine overdose is real. According to Healthline, symptoms may include irregular heartbeat, muscle twitching, and hallucinations. Especially if you consume more than 500 mg of caffeine in a short period.

Research published in ScienceDirect suggests that consuming over 500 mg of caffeine may lead to adverse health effects in some individuals.

According to the Dietary Guidelines for Americans (2015–2020), moderate coffee consumption—up to 400 mg of caffeine per day—can be part of a healthy diet.

FAQs about nitro cold brew coffees

Before I close off this article, let’s quickly go over a few key questions people have when making a nitro cold brew at home.

Who knows, maybe this will answer one of the questions you had as well!

Why does nitro cold brew taste sweeter?

The nitrogen gas creates a smooth mouthfeel and naturally enhances sweetness, without needing sugar or syrups.

Is nitro cold brew stronger than espresso?

Not necessarily. Nitro has more caffeine per ounce than regular coffee but less than a concentrated espresso shot. It’s smoother and easier to drink in larger quantities.

Is nitro cold brew less acidic?

Yes, because it’s brewed cold and not heated, nitro retains fewer acids, making it smoother on the stomach and naturally low in bitterness.

Final thoughts

Nitro cold brew isn’t just a trendy coffee—it’s a smooth, high-caffeine option that’s easy to make at home and enjoyable year-round.

From its naturally creamy texture to its energy boost, it’s a favorite among coffee drinkers who want a bold cup without bitterness.

I’ve tested nitro brews side-by-side with cold brew and iced coffee using different beans, roast levels, and steep times—this drink truly delivers when brewed right.

Now that you know what it is, how it tastes, and how to make it—will you try making your own?

Let me know in the comments if you’ve tasted the difference!
