Three NitroBrew Hacks for Home Brewers

NitroBrew is designed to infuse nitrogen into any drink. That said, it is indeed a system originally designed for beer. It lets you take your favorite beer from a can, a bottle or a growler and pour it as a classic nitro style beer in less than a minute.

Typical consumer uses 12 oz of commercial, carbonated beer with the NitroBrew system. NitroBrew of course infuses a substantial amount of nitrogen (in fact, a LOT more than your typical nitro style beer dispensed in a tap system). Moreover, NitroBrew also reduces carbonation to that perfect 1.25 – 1.4 volumes to give you the classic nitro pour and the smooth, creamy goodness.

With NitroBrew system, infuse nitrogen, carbonate or whatever!

Many NitroBrew customers are also passionate home brewers. For these creative souls, here are a few ideas to get out even more from the NitroBrew system.

Home brewed beer, may come carbonated perfectly like a commercial beer, or may be not. May be the beer is taken straight out of fermentation and never carbonated to begin with. Either way, you can pour a nitro style beer from whatever you have.

With many possible beer styles and carbonation levels you can work with, NitroBrew system gives you a range of options. Let us start with the simplest hacks first and then drill this down:

1. Make a nitro version of your homebrew in a minute, right after fermentation and/aging. No need to carbonate the beer first. Fill your kettle with about 12 oz of your chilled homebrew. If the beer is still warm, let sit on ice for a minute while you arrange the charging system. Connect beer gas (~70% nitrogen, ~30% CO2- you can also use somewhat different gas composition as well with adjustments on total pressure) to the charger. Adjust gas supply pressure to about 35-45 psi pressure. Now charge the kettle like you normally would, shake and pour through the dispense valve for that classic nitro beer.

You can use more beer than 12 oz, if you can make adjustments on supply pressure. Experiment to figure out what suits your taste.

2. Don’t have beer gas mixture? No problem. After you poured your homebrew and chilled it in the kettle, add a shot of 100% CO2 first (use a gas supply pressure of about 12-25 psi) and shake the kettle. Then NitroBrew with 100% , nitrogen (or even compressed air) at a pressure setting of 45 psi. usual pressures). Serve like you normally dispense from the NitroBrew system.

3. NitroBrew as a simple, on-demand carbonation system. You made that nice beer, and you can’t wait another week or more to fully carbonate by “bottle conditioning” with yeast and added sugar. NitroBrew can double as a simple carbonation system, and get your your beer to drink in just a few minutes. You can take your beer right out of fermentation (and aging, as well, you purists out there!). Depending on the fermentation temperature, it is likely that your beer is carbonated at about 1 volume.

Pour 12 oz of beer- into your kettle and close the lid. Since NitroBrew system is all stainless-steel, you can quickly chill your beer by placing the kettle on ice. Connect the charger to a CO2 supply. Set the CO2 regulator to between 25-35 psi and NitroBrew like you normally would. Shake the kettle and let sit for a few minutes upright on ice. By the way, NitroBrew recommends shaking the kettle by holding the kettle itself, not by the kettle-handle. With the kettle still being upright, slowly vent the kettle pressure by gently pushing on the valve push button. When the pressure is safely vented, the pressure safety lock will disengage and you will be able to open the lid. Just pour out your beer into a serving glass directly from the open kettle. As an aside, you can fill more than 12 oz of beer- even 16 oz, but you may need to use higher pressure for charging. Experiment and see what works. Note however that we recommend that you do not exceed about 45 psi gas pressure.

While we are on the subject of beer carbonation, did we mention that you can use the same process to carbonate numerous other drinks, like sodas, juices, etc ?

10 Minutes with NitroBrew Inventor Dr. Murthy Tata

10 Minutes with NitroBrew Inventor Dr. Murthy Tata


Inventor and engineer Murthy Tata talks about the invention that made him an unlikely coffee leader, the NitroBrew.

You probably don’t see a lot of coverage of engineers here, but at Barista Magazine we want to expand the coffee community and share stories from a wide variety of its members. We’ve covered the NitroBrew, the device that allows you infuse nitrogen into any drink one cup at a time, on this blog before. Now, we sit down with the inventor, Dr. Murthy Tata, to talk about the intersection of coffee, science, and the how his passion for food and drink led him to invent the NitroBrew. 

Ashley Rodriguez: What was your first experience with coffee?

Murthy Tata: I was probably 8 or 9 years old when my grandma filled milk in a glass that had a little coffee in it and gave it to me. I remember initially complaining about having to drink ‘contaminated’ milk. But to my surprise, it tasted better than usual milk. Over the years coffee replaced more and more of the milk.

AR: Have you always had a knack for inventing things?

MT: I am always tinkering. Thankfully, I was able to follow through on some of my projects, including NitroBrew and put them out in the marketplace as mature products. I usually take an unconventional approach to familiar problems. We are known for our innovative and novel solutions at QuantiPerm (a company I started in 2003 with products in food and beverage, biotechnology and brewing industries).


Murthy is the founder of QuantiPerm, and has since opened a separate branch to respond to the popularity of NitroBrew.

AR: What inspired you to invent the NitroBrew?

MT: Inspiration for the NitroBrew idea comes from my career in the brewing industry. Nitro-style beers, in my opinion offer an amazing drinking experience with a silky-smooth texture, and a very different way of presenting flavors.

I developed a process to infuse nitrogen for Leinenkugel Brewing during the early 1990s. It turned out to be an amazing beer called Creamy Draft. People just loved it. But after the initial excitement, we learned that the customer experience didn’t work out the way we had imagined. We learned quickly that no matter how great your nitro style beer is, maintaining a consistent quality throughout the distribution system and at the bars was going to be a very difficult proposition. With these beers, unlike the normally carbonated beer styles, any changes in temperature, beer gas composition or pressure changes at retail adversely affect the quality. How many times have you had a nitro beer at a bar that had no head of foam? That was disappointing.

Infusing coffee with nitrogen is a more recent phenomenon. Initially, I was skeptical. I reached out to some specialty coffee folks around here to learn about how to do nitro coffee and experimented with a few of their coffees. It was a learning experience. We learnt that the coffee variety and the roasting style may either go very well or not so well with the typical beer gas infusion. The carbon dioxide levels in the gas can impart really astringent taste for certain styles, although the effect can be mostly overcome for certain styles when you use sweeteners, flavorings, or cream.

AR: What type of coffees do you enjoy on the NitroBrew?

MT: I like all varieties. That said, low-acid, medium roast varieties are my favorites. While almost all of these styles work amazingly well with NitroBrew, many of them don’t even need to be cold-brewed. Often at home, I just collect my drip coffee onto ice and NitroBrew it right away.

AR: What other jobs have you had? How did you get to this point?

MT: I am a chemical engineer. I had a brief stint in the petroleum industry. After graduate studies in biochemical engineering, I went to work in the brewing industry R&D for several years. I worked in all areas: fermentation, brewery processes, and also a little in chemistry of beer. Later I also worked in beer packaging and had the technical responsibility for putting beer in plastic bottles for the first time in North America. I accepted an invitation to work in Motorola’s Biochip development business in Arizona where we were developing chips to study gene expression profiles in biological samples.

I founded QuantiPerm in 2003 producing R&D instruments on a technology I patented (for rapid, nondestructive testing of packaging materials). QuantiPerm diversified its product offerings over the years to include carbonation systems, dissolved gas analyzers, bioprocess monitors, water treatment systems, etc. NitroBrew happens to be one of the recent QuantiPerm products, and since it caters to a different market, it was spun off as a separate company in 2014.

AR: Are you working on any other projects? Any other ways to improve coffee?

MT: We are eager to finish up some projects relating to fermentation monitoring and control systems for both commercial breweries as well as the home brewer market. In general, we don’t like to launch into a product line unless we feel like we can make a strong contribution.

In the coffee realm, we had been asked about kegerator-style in-line nitrogenation systems and we are looking into the possibilities and are working with larger commercial partners.

AR: What do you want people to know about you?

MT: As a consumer, I am very demanding of what I buy. So as an entrepreneur, I strive to offer the finest products that our customers are thrilled about. This is something the entire crew here strives to provide to our customers. Today, more than ever, it is our customers that come up with amazing and creative drinks. It is an entirely new level of satisfaction whenever our customers share their creations that include NitroBrew.

I draw inspiration from my family, friends, colleagues, and also our customers. I feel awed by the fact that all these amazing people share a part, however small, of their lives with me. While money can be important, I derive most pleasure from doing the little things everyday that make a difference.
