Fresh & Faster: The Rise of Vacuum Cold Brew Coffee

Vacuum Cold Brew Coffee – A Faster and Fresher Way of Brewing Coffee

Coffee, for many, is the magical potion that gives them the energy to start their day. A good cup of coffee can make all the difference to one’s mood.

For some, a strong, rich cup of coffee is essential while for others, a smooth, mellow and well-balanced coffee is the go-to. With the rise of specialty coffee, many different brewing methods have been introduced.

Some prefer to stick the classic ways like drip coffee or French press, while others experiment with Aeropress, pour-over, and even Turkish coffee. One of the relatively newer methods to have emerged in the last few years is Vacuum Cold Brew.

The brewing method is gaining popularity in the coffee community due to its ability to brew a delicious cup of coffee in just a few minutes, while also maintaining the freshness and quality of the coffee.

What is Vacuum Cold Brew?

Vacuum Cold Brew is a unique process of coffee extraction that utilizes vacuum pressure to create a smooth and rich coffee concentrate. It uses a vacuum-sealed chamber to extract coffee from the beans, which is then filtered and concentrated.

The vacuum extracts the coffee while also reducing the boiling point of water, making it a quicker process. The process happens very quickly; one batch of cold brew can be completed in two to three minutes.

The low boiling point also prevents the extraction of bitter compounds, which is a common problem faced in other brewing methods. The end result is a smooth and strong cup of coffee that’s perfect for coffee enthusiasts who are looking for something different from their regular cup of coffee.

The 4 Advantages of Vacuum Cold Brew:

Coffee Brews Much Faster in a Vacuum:

One standout advantage of vacuum cold brew is its fast brewing time. Coffee brewed using other methods takes hours to achieve the same taste and strength as a vacuum cold brew.

The vacuum brewing process reduces the brewing time drastically, without compromising the quality of the coffee. This is because the vacuum lowers the boiling point of water, which means that it takes less time for the water to extract all the coffee goodness from the beans.

Additionally, the vacuum extraction process ensures that the coffee flavor is stable and consistent throughout the brew.

Vacuum Coffee Shelf Life:

Another advantage of vacuum cold brew is the shelf life of the coffee.

Because the extraction happens in a vacuum-sealed container, there is little to no oxidation of the coffee. This results in a longer shelf life for the brewed coffee.

When compared to other cold brew methods, which usually last around a week, vacuum cold brew lasts much longer. Coffee brewed this way can be kept in the refrigerator for about a month, without any loss of quality.

Reduced Risk of Contamination:

The vacuum brewing process eliminates the need for a paper filter or metal mesh, which means there’s no chance of contamination by these filters. With other brewing methods, contamination by the paper filters or metal filters can occur.

Metal filters can even leave behind a metallic taste, ruining the taste of the coffee. Vacuum cold Brew, therefore, presents purity and hygiene, which is great for coffee enthusiasts who are particular about the quality of their coffee.

No need for refrigeration:

Refrigeration is not required for vacuum cold brew. Unlike other brewing methods that need to be refrigerated to maintain their freshness, vacuum cold brew can be stored at room temperature, which makes it a cost-effective option.

The brewing process can also be done without the need for electricity, which makes it an excellent option for coffee lovers who are on the go.

The Process of Vacuum Coffee Brewing

Two Important Things That Happen During Vacuum Coffee Brewing:

During vacuum coffee brewing, there are two important things that happen; grounds saturation and lower boiling point of water. The grounds saturation is evident because the coffee is brewed in a vacuum-sealed chamber, allowing the coffee to saturate fully, resulting in a delicious and flavorful cup of coffee.

Additionally, the low boiling point of water used during the brewing process prevents the extraction of bitter compounds, resulting in a smoother and less acidic cup of coffee.

Lower Boiling Point:

Vacuum cold brew reduces the boiling point of water, which means that the boiling point temperature is reduced.

This, in turn, helps to extract soluble solids from coffee beans at a lower temperature than other brewing techniques. Kintetic energy, which is responsible for breakdown and release of compounds from the coffee grounds, gets a boost because of the low boiling point, providing for an efficient extraction of flavor components.

As mentioned earlier, this method results in a smoother and mellow flavor, compared to other brewing methods that generally have a bitter taste.

Why Vacuum Brewing is Exciting:


Vacuum cold brew has the advantage of being a cheaper option compared to other cold brewing methods.

The process is straightforward, and the equipment required is affordable. The brewing process also uses less water compared to other methods, which is great for coffee lovers who are conscious of their water usage.


Since vacuum cold brew requires a shorter brewing time, the coffee brewed is significantly fresher than other methods. The vacuum-sealed chamber creates an environment that minimizes oxidation and keeps the coffee fresh for a long time.

As the time between brewing and consumption is significantly reduced, you can enjoy a fresher and tastier coffee.

Reduced risk of contamination:

Another advantage of vacuum cold brew is the reduced risk of contamination.

The vacuum-sealed nature of the brewing process ensures that there’s minimal contact with air, which can quickly oxidize coffee. Also, as the vacuum brewing process excludes the use of filters, there is little room for contamination.

In conclusion, Vacuum cold brew is becoming a popular brewing method, especially for those who are passionate about coffee. The process is gaining momentum because of its ability to produce a flavorful and delicious cup of coffee, in a matter of minutes.

The fast brewing process, longer shelf life, reduced risk of contamination, and cheaper equipment are just a few of the many advantages vacuum cold brew has over other brewing processes. If you’re a coffee enthusiast looking for a new and exciting way to brew coffee, vacuum cold brew is definitely worth a try.

In conclusion, the rise of vacuum cold brew coffee has revolutionized the way coffee enthusiasts brew their favorite beverage. The vacuum brewing process presents a range of benefits, including faster brewing time, longer shelf life, reduced risk of contamination, and affordability.

Vacuum cold brew coffee makers, such as the RAIN Tech from Bkon, Dash Fast Cold Brew Coffee Maker, and Vac One Coffee Air Brewer, are available in the market to cater to different needs. The future of vacuum technology goes beyond coffee, and there are exciting possibilities for it to be applied in infused waters, spirits, tea, and other shelf-stable products.

Along with offering a practical solution to coffee brewing, it also has the potential to impact general health by utilizing natural preservatives. As the coffee industry continues to evolve, the future of vacuum tech looks promising with more advanced and innovative brewing methods that can improve our coffee drinking experiences.
