VacOne Cold Brewer Review




Experts have developed an imaginable way to make a cup of the cafe — French printing, cold brewing, vitamin-infused, or IoT-enabled infusions.

As long as coffee heads and coffee lovers are present around the world, people will invent new techniques to make things even more nuanced and flavored.

I always liked to research new and innovative products made by these exceedingly creative heads as they make our lives either better or more efficient. I researched a brand new product called VacOne Coffee Air Brewer which I will review for you, the coffee lover.

Cold-brew does not refer to the temperature of the final product but to the process of coffee preparation. Beans are soaked for a long time, usually 12 hours or more in room temperature water.

Iced coffee is brewed by means of hot water, which is then poured on ice to extract the flavor that results in an iced-chilled cup of coffee.

Benefits of Brewing

More sweetness

Speaking of a new and innovative coffee maker on the market, the coffee extraction of VacOne Cold-Brew is smooth, unlike any other brew. Longer braking time provides more flavor extraction in the water. It creates a less watered-down taste for a more concentrated coffee. With this method, we produce a flavorful coffee that maximizes taste and reduces bitterness.

Less acidity

During an interview, Umaña (the manufacturer of VacOne brewer) said that the ground coffee forms a naturally occurring filter that strains and removes the cream (the tan, the foamy layer of an espresso), which is quite bitter because of the degradation of carbon dioxide. A sweeter cup of coffee is the result

VacOne Coffee Air Brewer and Cold Brewer

VacOne innovative and new air brewing system uses a vacuum to create suction and pull water through the ground coffee, extracting more flavor in a shorter amount of time. VacTec® reduces the bitter taste and significantly lowers the acidity in hot coffee. The result is a smooth, intense and sweet glass of cold brew in record time.

This means that in just 30 seconds a full, distinctly sweet cup of hot coffee, or cold brew can be made in just 4 minutes. For me that’s pretty quick with good results.

Moreover, it is portable and has an easy coffee purification system with no paper-filter waste created. That’s because the internal metal filter is good for hundreds of applications.

VacOne is Unique

VacOne produces enough pressure to produce an espresso-like shot. It has a kick, is sweet, and is very intense.

VacOne is distinguished from other manual brewers. through its patented Vacuum Extraction System which uses negative pressure to force water through a bed of ground coffee. It extracts more of the flavors of coffee while reducing bitterness.

This allows for brewing with any grind size, from very fine to very coarse. Different grind sizes enable the preparation of a diverse range of brew types and cup profiles – from hot coffee to cold brew – all with the same machine making this device very versatile and efficient.

The taste of the cold brew is so unique. It gives you a chilled, caffeinated drink that tastes fuller with less acidity than traditional iced coffee. It’s an excellent way to fix your caffeine, especially in the heat of the year. Brewed coffee is quite expensive to buy in café shops, and that’s why people brew at home.

It usually takes a couple of hours to enjoy. That has changed with VacOne. You can now brew yourself almost immediately with less effort.

This process can take as little as one minute rather than taking hours as traditional cold brewers do.

VacOne is a rechargeable battery-powered device, and also comes with its own carafe. It is intended for the use of a pitcher (if you are doing multiple cups) or a drinking vessel (if you’re making a single-serve drink).

How Does VacOne Works?

The new brewing system, VacOne, using “vacuum extraction technology” comes from an inventor who is a coffee expert in Colombia and wanted to make coffee like an espresso. Place your cafe on the top and pour over it hot water, then push the button and fire up the electric system of VacOne. In the glass chamber, it creates a vacuum to draw the water through the coffee grind which acts as a natural filter while the water extracts all the flavor and aroma into the glass carafe.

The air is essentially removed from the glass carafe which forms a vacuum, forcing water from the top container to filter under pressure through the coffee bed. This is why you can make a drink quite like espresso. The vacuum is strong and forces the water through the fine-ground coffee.

VacOne Advantage to Brew Coffee

There is a great and wonderful feeling that comes along with making cold brew coffee. It tastes much better than traditional iced coffee.

Like many types of coffee, cold brew coffee can be expensive in coffee shops. It’s a good reason most people prefer to brew it from the comfort of their homes. The usual issue with making it at home is that it would take at least 12 hours before your cup is ready. This is why the VacOne device was invented.

Just in few minutes, the device can help you make your cup of cold brew coffee. This will save you the stress of brewing your coffee over long periods.

Coffee Preparation

To use the device, pour your ground coffee into it, turn hot water into it, and then cover it up with the lid. After some seconds of allowing the coffee to soak in hot water, press the button you see on top of the device and the extraction will begin.

In order to find the flavors that suit your taste, you can reduce or increase its water, the amount of coffee, the brewing duration, and the type of grind size.

The device does not only work really fast and efficiently, and its brewing process reduces the amount of bitterness that naturally comes with any coffee. Most of the bitter taste in coffee comes from the foam(crema) that rises from the top. This brewing device helps remove most of the crema.

Other Features of the VacOne Device

Apart from making your coffee taste a lot better, it brews your coffee with a lot of speed and efficiency. It comes with waterproof construction and also a rechargeable battery, an integrated metal mesh, and of course a borosilicate glass carafe that has a silicon base.

The VacOne is a perfect brewer for coffee enthusiasts who have taste for smooth and quality brewed coffee. The device uses a vactec brewing technology, which speeds up the process of extracting the coffee’s sugar, caffeine, and all of its natural oils.

All you have to do is add hot water to the coffee, and you are sure of the device turning it into a smoothly-brewed cold glass of coffee within minutes.

Steps to Properly Using the Device

  2. Hi there Michael

    Great article with great photos which is darm and mysterious like the coffee. I love the jazz music in the video and great descriptions of the coffee and how to make the coffee. I like the dual comparison on the cold and hot coffee method. I would like to have one too. Especially that it takes the crema away which causes the bitterness. Something which I did not know. You have great knowledge about coffee and written with a sophisticated feel. Great job.
