FrankOne Vacuum Coffee Brewer Review

FrankOne integrates a proprietary vacuum brewing tech, VacTec, that allows it to full-bodied better coffee in as little as four minutes. Taste-wise, this device hardly disappoints. You can expect a cold brew that’s incredibly smooth and full-bodied without the bitterness often associated with traditional cold brews.

I am not going to insist on this one too much, since this is a clone of VacOne, but only sold in Canada. If you are a Canadian trying to buy this, you might want to buy it on Amazon.com. It will be much cheaper, even with the extra shipping added.

Factors to Consider When Choosing a Vacuum Cold Brew Coffee Maker

Here are four key factors to consider when choosing the best vacuum cold brewer.

Capacity and Size

You want a coffee maker with a perfect balance between your brew size requirements and space in your kitchen. A larger capacity will suffice if you entertain often or have a large family. For users living alone, a compact, single-cup model will do the job. The typical capacity of products in this roundup is 14-20 fl. oz.

Materials Used and Durability

A solidly built coffee maker will withstand regular use and last longer.

Regarding carafes, the glass options are chemically inert but are more fragile. On the other hand, BPA-free plastic carafes are lightweight and less prone to breakage. Plus, they can offer better heat retention than glass, ensuring that your cold brew remains at the desired temperature for longer.

Filtration System

Brewers work with various types of filters, including metal mesh and paper. A fine mesh filter is the most effective choice for a vacuum coffee machine. It ensures your brew will be smooth and free of sediment, not to mention it’s reusable.

Ease of Use and Cleaning

Clear instructions, intuitive controls, and easy setup can significantly impact your overall experience with a vacuum cold brew coffee maker. The parts should be removable and waterproof for hassle-free cleaning.

Tips for Getting the Best Results with a Vacuum Cold Brew Coffee Maker

So, you’re wondering how to achieve the best results with a vacuum cold-brew coffee maker. Find below the factors that matter.

Grind Size and Coffee-to-Water Ratio

The recommended grind size for vacuum cold brew coffee is coarse. It allows for better water flow and prevents over-extraction. You can experiment with a medium-coarse, or even medium grind size

A higher coffee-to-water ratio will result in a stronger, more concentrated coffee, while a lower ratio will produce a milder brew. The expert recommendation for cold brews is a 1:8 ratio (8 grams of water for every gram of coffee).

Brewing Time and Temperature

The longer the brewing time, the more flavors you extract from the coffee grounds. However, be cautious not to over-extract, as this can lead to bitterness.

While cold brew coffee can be made at room temperature or with refrigerated water, each option produces slightly different results.

Generally, room temperature speeds up extraction, producing the same sweet, less acidic coffee. Refrigerated water, on the other hand, requires a longer extraction time.

Experimentation with Coffee Beans

Don’t hesitates to try different beans and roasts to discover the perfect flavor profile for your cold brew. Beans from coffee-dominated regions in Asia and South America come highly recommended for cold brews. You can always expect a smooth flavor from light-medium roast but never try cold brewing with instant coffee.

Adjust Your Expectations

If you are used with the immersion cold brew, (Hario Mizudashi, Oxo, Filtron, or the Mason Jar), you will have to tweak your brew to match that. The taste you get with the default settings will be a little different, though it’s still amazing.

Bottom Line

Thus far, we’ve explored various options and factors to consider when looking for the best vacuum cold brew coffee maker for your needs.

Making an informed decision won’t just save you time and effort. More importantly, it will also make a tangible difference in the flavor and quality of your cold brew coffee. So, take your time.
