    The Keurig B40 Elite Brewing System is a neat single-serve coffeemaker that uses K-cups. It is both fast and easy to use and it can make a fresh cup of gourmet coffee, tea or hot chocolate in less than a minute. Choose between two different brew-sizes, either a 7.25oz. cup or a 9.25oz. mug.

    Posted December 20, 2012 by


    he Keurig B40 Elite Brewing System is a small single-serve brewer, but still has a generous water reservoir and both regular and travel-size mugs fit. When I first opened the box I got impressed of how it looked and felt. I knew before I bought it online that it was made of plastic. I was afraid the coffeemaker would look cheapish and the plastic feel flimsy. After some research I have found out that the plastic used in this Keurig machine is completely free of any Bisphenol A (BPA).  The quality of the construction is definitely good and it feels really sturdy. The Keurig B40 hasn’t the elegant and exclusive look some single-serve brewers made of stainless steel have, but it still looks good.

    Initial setup

    The initial setup of the Keurig B40 is both quick and easy. You only need to run a brewing cycle without a K-cup in the machine. Before I could run the rinsing cycle I needed to fill the water reservoir. The water reservoir is located on the left side of the brewer and is made of clear plastic so you easily can see how much water is left. The reservoir is detachable which I think is a good idea and makes it easier and more convenient to fill.  The capacity of 48 ounces (about 1400ml) makes me on average 6 mugs (7.25oz.) before I have to refill the reservoir.

    The coffee machine will take approximately 4 minutes to heat the water before the first brewing cycle. A red “heating” light indicates that it is heating the water. It might also take up to 15 seconds between two brewing cycles to heat more water.  When the heating process is finished the red “heating” light extinguishes and the brew lights illuminates. By pressing the “small mug” button you start the rinsing cycle. That’s it, you are now ready to brew your first cup of coffee.

    Brewing my first cup


    Lift up the handle and insert a K-Cup before you press the handle down again.

    I find one of the 12 K-Cups that came with the machine and put it in. There are two sharp needles, one above and one at the bottom of the K-Cup holder, that pierce the K-Cup when you pull the grey/silver handle down. When the handle is pulled all the way down you can hear a “click” and the two brew buttons (7.25oz. and 9.25oz.) starts to flash. I go for the mug size (9.25oz.) and the machine starts filling my mug straight away.

    Most single serve coffeemakers have a pump to pressurize the water and this Keurig B40 is no exception. The pump makes some noise and the machine vibrates a bit, but this only last for about five seconds. If I compare the noise and vibrations to other similar coffee machines I have to say that the B40 is about average.

    Approximately after 30 seconds my first cup of coffee is finished brewing. The result is a very decent cup of coffee, definitely hot but maybe not as strong as I normally like it (I like my coffee very strong). I therefore decide to brew a new cup straight away, but this time I will go for the smaller cup size (7.25oz.). The second cup is prefect! The coffee is both rich and bold. When I had finished my cup of coffee I was pleased to see that there were no sediments/grinds left in the bottom of my cup.

    I have now figured out that you can buy extra bold K-Cups, which makes strong coffee even if you choose to make a big mug (9.25oz.). One of the reason I like the K-Cups machines is the wide range of different K-Cups available.

    When you are finished brewing your cup of coffee, you only need to remove the used K-Cup. You don’t have to clean any filters or remove any messy coffee grounds. The used K-Cups are almost dry when you remove them from the machine and the risk of any spills is minimal.


    Keurig B40 Elite Parts and Features

    Control panel

    The control panel is self-explanatory, but I will quickly go through them and explain some of the features.

    The “Add water”-light illuminates (blue light) when the water level in the reservoir is low or the reservoir is removed or not properly placed.

    Keurig B40 Control PanelThe next light on the control panel is the “De-scale”-light. When this light illuminates, it means that the Keurig B40 has detected that some lime scale interferes with the operation of the coffeemaker. It is also recommended to de-scale the machine every 6 months or more often if you live in an area with lots of minerals in your water.

    If you don’t regularly de-scale your coffee machine, there is a bigger risk the machine won’t last as long. The pump and nozzles can clog up and get broken. Also your coffee might get a foul taste.

    The “Heating”-light comes on when you turn on the coffeemaker and tells you that it is preheating the water, this can take up to 4 minutes. You can also see the light illuminates between two cycles, but just for a brief moment, up to 15 seconds.

    The “Auto off”-light indicates (with a green light) that the automatic shut-off function is turned on. When the automatic shut-off function is on, the brewer will turn itself off if it has been inactive for 2 hours. This function can easily be turned off by pressing the small black button right of the light, but I personally always keep it on for safety and to save electricity.

    The last and bottom light is the power on light and it is self-explanatory so I don’t think I need to explain it for you.


    The Keurig B40 Elite Brewing System is a great coffeemaker, it makes good coffee fast and easy. I would have loved if Keurig made the coffeemaker look a bit more appealing, but it is definitely not a deal breaker. The B40 is one of Keurig’s smallest models and doesn’t have all the bells and whistles as bigger and more expensive models. I personally don’t miss any functions and I think it is a great choice if you are looking for a single serve coffeemaker for your home. The K-Cups are little bit expensive, but I think the wide range available and the taste of the coffee make it worth it. Everybody shouldn’t have any problem finding a favorite!


    • Reasonable price.
    • Good building quality.
    • Makes great coffee, both hot and strong.
    • BPA-free plastic.


    • Expensive K-Cups.
