The OXO On Barista Brain 46894A uses the latest technology to bring you the best-tasting coffee so far. It uses paper filters and it has to be descaled with a descaling solution. It comes with a heat resistant stainless-steel carafe that will hold your coffee hot for longer. It’s perfect for people who want a simple, yet elegant coffee machine on their counter top.



OXO On Barista Brain 46894A is a simple, easy to use coffee maker. And while it might have a few less options than some of our other top picks, OXO On is elegant with just one button to master in order to fully operate it. It comes with a  double walled stainless-steel carafe able to hold up to nine cups of coffee. Nevertheless, this multifunctional coffee maker can make a single cups worth of coffee as well.

With its sleek, elegant exterior and its “high-tech” interior, the OXO On Barista Brain 46894A is one of the best coffee makers on the market. It’s manufactured from the best quality material, going through rigorous testing in order to ensure that each machine satisfies a certain level of standard. The metallic carafe is made from double-walled stainless steel in order to provide a vessel that will hold your coffee hot for longer.

OXO On prides itself with a built-in high-end microprocessor that controls the quality of each individual batch. This internal component makes sure that the coffee is brewed under perfect conditions each time you press the start button. This model is almost unique on the market thanks to its one-dial interface that only has one rotatable button you can control every function with. This means that by pressing and turning you get to select your preferred option. Once you do, your preference will show on the small backlit screen.

The OXO On Barista Brain 46894A has a 24-hour programable start which means you can set it up so you get to wake up to the smell of freshly brewed coffee. Other features include a single cup option which brews just one cups worth of your favorite beverage. Another useful feature is the freshness timer. This specialty timer turns on the moment you take the carafe out, once the coffee is brewed. Since your coffee is freshest, and it retains most of its best qualities during the first hour, the timer will conveniently count up to 60 minutes so you can keep track of the time you made that specific batch.

To make your coffee as perfect as possible, the OXO On Barista Brain 46894A heats up the water to temperatures between 197.6 and 204.8F which was established as the best optimal temperature for brewing. Once the process starts, unlike with some other coffee makers, the 46894A releases the hot water in waves, creating an interesting effect you can observe in the reservoir. These water intervals then go through a rainmaker showerhead that is a bit wider than standard, in order to cover the coffee beans evenly. Once your coffee reaches its final destination in the carafe, the OXO On Barista Brain 46894A has another surprise for you. In order to ensure every sip you take tastes exactly the same as the first one, the carafe has a removable mixing tube that slowly mixes the coffee as you pour it into your cup.

All these features made sure that the coffee produced by OXO On Barista Brain 46894A ends up in the company of the best of the best with the Specialty Coffee Association of America. Being recommended by this institution means that this coffee maker had to meet very high standards for quality, brewing time, water temperature and more. There aren’t many coffee makers in our review that have this esteemed certification.

Ease of use

As we mentioned before, the OXO On Barista Brain 46894A is very easy to operate. All commands are accessible through the one-dial interface by pressing and turning the rotatable button. This coffee maker comes without a gold-tone filter, which means you’ll have to buy disposable filters additionally. Aside from the extra cost, having a coffee machine that uses paper filters means that you won’t have to clean it nearly as often.

Cleaning/descaling your coffee maker is as important as knowing how to properly use it. Like many other coffee machines, the OXO On Barista Brain 46894A will display a warning sign on its display alerting you to clean it after every 90 cycles. However, if the water in your house is harder than normal, you might have to descale your appliance more often. The recommended descaling solution can be bought on their official website.

OXO On Barista Brain 46894A is a 9-cup coffee maker that produces delicious, high quality coffee with very little hassle. It’s equipped with the latest components in order to ensure every batch you make tastes exactly the same. It uses disposable paper filters and the stainless steel carafe isn’t dishwasher safe.


This coffee machine can be bought directly from the OXO On website for $199.99. This price includes the coffee maker, one coffee scoop and ten disposable filters. Additional filters can also be bought on the official site for $12.99 for 100 paper filters. The recommended descaling solution will cost you another $14.99. This product comes with a two-year warranty valid from the date of purchase of your new coffee maker.
