Nitrogen Gas Infuses Benefits to Winemaking Industry

Nitrogen Infusion for WinemakersOxidation, bacteria, and spoilage are a winemaker’s worst enemies, threatening profits and sales. Nitrogen can be used to help prevent oxidation, which occurs when wine is exposed to too much oxygen. And the use of nitrogen throughout various stages of the winemaking process helps preserve color, flavor, and aroma of any wine.

Why Nitrogen in the winemaking process?

Nitrogen is a colorless and odorless gas, which makes it possible to use without wine/wine bottle discoloration or a negative impact on the wine’s taste. Specifically, nitrogen gas can be used during transfer and bottling of any wine to help reduce waste, save the winemaker money, increase employee safety, and reduce environmental impact.

Nitrogen’s Role in Winemaking

Nitrogen gas can be used to prevent oxidation during three specific stages of the winemaking process.

  • Flushing: There is a risk of too much oxygen exposure when wine is transferred between containers through housing pumps and hoses. By flushing these pumps, hoses, and filling bowls before bottling begins, unwanted oxidation can be prevented early on.
  • Sparging: Wine naturally dissolves oxygen during the fermentation and aging process, so sparging can come in handy as a means of applying nitrogen in the form of extremely small gas bubbles. This works to remove any released oxygen and preserve the wine.
  • Blanketing: When it comes time to bottle wine, bottles can be flushed with nitrogen both before and after filling. Nitrogen can also be applied to partially filled barrels or tanks to displace oxygen.

Additional Nitrogen Benefits to Winemakers

Winemakers of all sizes can benefit from using nitrogen in the process by cutting down on waste caused by oxidation and spoilage. And costs associated with setting up on-site nitrogen generation equipment can pay for itself many times in the long-term.
On Site Gas Systems specializes in installing nitrogen generation systems. Whether you’re already using nitrogen gas in your process or are new to the idea, having an on-site nitrogen generation source can simplify your business and improve workplace safety.
And when you don’t rely on diesel delivery trucks to supply your nitrogen each month, you’ll help reduce your company’s carbon footprint. You’ll also save anywhere from 40% to 80% compared to delivered nitrogen, the price of which can fluctuate throughout the year.
The use of nitrogen in winemaking isn’t new, but we’re revolutionizing the way winemakers access nitrogen to make the process more profitable for you. To learn more about our nitrogen generation services, contact On Site Gas Systems today. We’d love to speak with you about how our services can help support — and grow — your winemaking businesses.

Enhance your Cold Brew with a Nitrogen Kick

If you’ve frequented a coffee shop over the past few years, you might know that cold brew is becoming a hot commodity.
Some might confuse cold brew with iced coffee, but the two have fundamentally different preparations, and connoisseurs will be quick to point out a vast difference in quality. Iced coffee is traditionally brewed hot coffee that’s been chilled with ice. In contrast, cold brew derives from grounds that have been soaked for an extended period of time in water at room temperature (or that’s been chilled).
So what’s the fuss about cold- versus hot-brewed coffee? In boiling water, the oils in coffee grounds tend to oxidize and the acids break down, which can result in a bitter tang and the loss of nuanced flavor notes. But in room-temperature/cool water, those processes are slowed down significantly, lending cold brew a smoother, deeper, richer, sweeter flavor.
Traditional cold brew is all well and good, but customers are beginning to notice how luxurious this coffee can be with the simple infusion of nitrogen bubbles.

Nitro Coffee

Fans of craft beer are likely familiar with taps “on nitro.” Carbon dioxide creates the traditional head on beer, but a nitro brew is infused with nitrogen (or a nitrogen-CO2 combo) to create a creamier froth exemplified by the world-famous (and exactingly poured) Guinness stout. (Guinness pioneered nitrogen infusion.)
Technological innovation has allowed a similar method to boost cold-brewed coffee. Priming cold brew with tiny nitrogen bubbles, letting it sit one or two days, then pouring it through a restrictor plate to stimulate the gas, takes the libation to a whole new level and gives it a smooth, buttery, luscious mouthfeel. Some coffee drinkers accustomed to adding cream and sugar to their mugs find these ingredients unnecessary in nitrogen-stocked cold brew.
As with beer, either pure nitrogen or a blend of nitrogen and CO2 in varying proportions can be used depending on the desired flavor profile.
As java gourmands fall in love with the velvety charm of nitro coffee, more coffee shops (and amateur cold-brew fans) are integrating nitro capabilities into their operations. On Site Gas Systems recently debuted the Nitro-Blast setup, which is perfect for cranking up your cold brew.

Other Embellishments That Add to the Nitro Cold Brew Experience

The nitro makeover may be the most talked-about enhancement to cold brew these days, but there are plenty of other ways to tweak your cup. Common finishing ingredients to cold brew include salt and chocolate.
Ready to enhance your already delicious cold-brewed coffee? Turn to On Site Gas to take advantage of our state-of-the-art nitrogen generators, and embrace the creamy goodness that nitro coffee delivers. Contact us today to learn more about our offerings.

On-site Nitrogen Generators: Ideal for Winemaking

On-site Nitrogen GeneratorsToday it’s common practice to use inert gas during winemaking, but questions remain as to the correct use of nitrogen during the process. When wine is exposed to oxygen, its quality, stability and longevity are negatively affected. For this reason, winemakers use nitrogen in the ullage of wine containers to avoid oxidation, which leads to spoilage. Due to wine’s low solubility, nitrogen is the preferred inert gas for the winemaking process.
Nitrogen’s ability to eliminate oxygen prevents it from affecting the quality of the wine. And using nitrogen gas from a nitrogen generator from On Site Gas Systems can eliminate concerns related to oxygen exposure throughout the winemaking process.

Nitrogen Gas in Winemaking

Prolonged exposure to oxygen causes wine to turn into a vinegary substance, which is created as oxygen converts ethyl alcohol in wine to acetic acid. Winemakers use nitrogen at multiple points during the winemaking process to prevent this degeneration from occurring.
Use a nitrogen generator to prevent oxygen exposure throughout the winemaking process for:

  • Flushing: Nitrogen collected by generator is used to flush filter housing pumps, hoses, and to fill bowl directly before bottling begins.
  • Blanketing: Nitrogen from generator is applied to a vessel as a means to displace oxygen in the headspace of partially filled barrels, tanks, or bottles.
  • Sparging: This process refers to the practice of applying nitrogen from generator in the form of extremely small gas bubbles. This process removes any oxygen the wine has dissolved.

Specific Uses for Nitrogen Use During WineMaking Process

Nitrogen is used during bottling, transfer, and storage. By forming a nitrogen blanket during bottling, contact between oxygen and the surface of the wine is reduced, which prevents the development of bacteria and other microorganisms.

Transferring Wine

When preparing to move wine between containers, preventing exposure to oxygen requires flushing out hoses and blanketing the vessels by pumping nitrogen through them. Wine may also need to be sparged to remove any extant oxygen.


This process replaces evaporated wine by flushing nitrogen into the barrel’s ullage. At this stage of processing, nitrogen will blanket wine to eliminate oxygen.


When bottling wine, oxidation is a concern due to turbulence when mixing wine and air during the filling process. To ensure the integrity of wine, it is essential to flush bottles with nitrogen before and after filling.
Nitrogen generators from On Site Gas Systems provide cost effective and efficient solutions for manufacturers to prevent oxidation during the winemaking process. On-site nitrogen generators eliminate the need for expensive contracts, as well as handling high pressure nitrogen cylinders.
On Site Gas Systems nitrogen generators are safe, reliable, and easy to operate. And they allow you to generate nitrogen on-site so you will never run out of nitrogen again.
Our systems are used all around the world, including remote locations with harsh climates. If you are interested in learning more about the innovative nitrogen generators we offer or our “try before you buy” program, or if you want to know more about the benefits of a custom-designed nitrogen generator, contact On Site Gas Systems today.

Nitrogen-Infused Coffee and Beer: A Revolutionary Twist on the Gourmet Beverage.

NitroBrewCoffee and beer lovers have another gourmet beverage to enjoy: Nitro Coffee and Nitro Beer. Nitro Coffee and Nitro Beer are infused with tiny Nitrogen bubbles, which give iced coffee a foamy texture, similar to the frothy collar/head on top of a typical glass of beer. Nitrogen bubbles improve the flavor, texture, and frothiness of a beer’s collar. On Site Gas provides nitrogen generators that will froth up your beer and coffee business as well. Our new Nitro-Blast will provide enough nitrogen for up to five tap lines can be wall mounted to save space.

Iced Coffee Vs Cold-Brew, The Difference

Unlike iced coffee, Cold-Brew coffee is created by steeping coffee grounds in cold water. Once Nitrogen is infused into this coffee, the Cold-Brew coffee has a silky texture with a foamy head.

Creating Nitro Cold-Brew Coffee: The Process

Nitro Cold-Brew begins as regular Cold-Brew coffee in your typical coffee shop, whether it’s a small town business or an international powerhouse. Beneath the counter sits a single keg full of their Cold-Brew coffee. Two lines are attached to the keg: one line runs directly to the original Cold-Brew tap; the other line is infused with Nitrogen bubbles from the Nitro-Blast generator as it is poured from the Nitro tap.

Nitro Cold-Brew Coffee – What Coffee Lovers Can Expect

Cold-Brew exits the spout as a deep-brown coffee. As the Nitrogen infused coffee pours from the spout, cascading into the cup, it separates the darker brew from the lighter brew and then tops it off with a thick, foamy collar. This Nitro Cold-Brew coffee resembles a Guinness beer with the cascading reverse waterfall of bubbles, both visually and texturally. It also creates a natural sweetness lessening the need to add milk and sugar.

Nitro Beer: The replacement for Carbon Dioxide.

For years, the frothy collar on beer has been created by carbon dioxide, but some brewers have started creating what is referred to as Nitro Beer. Nitro Beer differs from traditional beer in that it is infused with Nitrogen. As the beer and Nitrogen interact, the beer becomes creamier, smoother and more evenly flavored. Furthermore, the beer has a frothier collar and a less bitter taste. Another benefit of using the Nitro-Blast Nitrogen Generator is safety, as this is a safer alternative to liquid dewars for a brewery or coffee shop.

Brewing Nitro Beer: The Process

For the most part, Nitrogen is insoluble in liquid: this is what gives the beverage its foamy, thick-mouth feel. And a piece of tap equipment specifically designed to enhance the texture of the beer adds to this effect. It’s called a restrictor plate, and it pushes beer through tiny holes directly before the beer enters the glass. This process creates the rising effect that’s typically seen when a carbonated beverage is poured into a glass.

Whether you need a PSA Nitrogen generator or a membrane Nitrogen generator, On Site Gas can custom build a Nitrogen generator for your company: We build Nitrogen generators for companies all over the world.

What to Consider When Purchasing a Nitrogen Generator.

NitroGeneratorCompanies thinking about purchasing a Nitrogen generator should consider what purity of Nitrogen they need. Nitrogen purity is usually expressed in the form of a percent. For example, 99 percent Nitrogen means the gas consists of 1 percent Oxygen, with the remaining 99 percent consisting of Nitrogen and other inert gases.
However, some high purity cases express the Nitrogen’s purity as parts per million by volume (PPMv) of Oxygen that remains in the product gas. Ten PPMv is equal to 99.999 percent Nitrogen and 10,000 PPMv equals 1 percent Oxygen. Determining the minimum purity level required for the applications at your facility is essential to ensure that you benefit the most from your on-site Nitrogen production. Our Nitrogen generators usually pay for themselves in less than 18 months.

On-Site Gas’ Self-Generated Nitrogen Gas Production Options: Pressure Swing Adsorption and Membrane Nitrogen Generators.

Pressure Swing Adsorption Nitrogen Generators

Pressure Swing Adsorption, which is commonly referred to as PSA, uses two vessels. These vessels are filled with CMS (carbon molecular sieve). While compressed air flows up through one vessel, the Oxygen is adsorbed, meanwhile the other vessel de-pressurizes some of the Nitrogen, which flows downward to desorb (drive-off) the moisture and Oxygen the first vessel previously collected. This process continues with one vessel performing adsorption and the other performing desorption. A full cycle includes several steps and usually only takes about two minutes.

Membrane Nitrogen Generator System

A membrane Nitrogen generating system uses hollow fibers of various lengths, materials, efficiencies and diameters. These hollow fibers consist of man-made polymers: their variances allow for selective permeation. Selective permeation is used to separate the gases from the stream of compressed air as it moves through the membranes.
Some vessels contain millions of hollow fibers. These vessels may be referred to as membranes or membrane bundles. In order to provide the capacity needed, these membranes are frequently installed parallel to one another. Semi-permeable fibers are designed to let the faster gases permeate the fiber walls and release into the surrounding atmosphere. These gases are carbon dioxide, Oxygen, water vapor and hydrogen. The membrane separation process does not involve the use of moving parts, which is beneficial for individuals who would like to avoid maintenance and keep things simple; however, other parts of a membrane Nitrogen generator do have moving parts and electrical components. Membrane Nitrogen generators are typically quiet and take up less space that their pressure swing adsorption counterparts do.

Nitrogen Generator Energy Costs

Energy costs are determined by the percentage of Nitrogen required: An N2 system that provides 95 percent purity takes approximately 2 standard cubic feet per minute of compressed air to provide 1 standard cubic feet per minute of Nitrogen.
Nitrogen Specs for Comparison Purposes

  • Food Packaging – about 99.5 percent for the majority of applications
  • Blanketing to avert hazardous conditions – anywhere from 95 to 97 percent.
  • Heat treating metals – materials and processes determine whether purity levels can be 97 percent or as high as 99.999 percent (10 parts per million of O2).
  • Blanketing vegetable oils (edible) – approximately 99.9 percent.
  • Printed Circuit Boards – “Lead Free” selective solder in most cases requires 99.999% (10 parts per million of O2). Both wave solder and reflow can require purities between 99.9% and 99.99%.
