How the Keurig B31 Mini Plus Personal Brewer Performed
Compared to the larger Keurig brewers, the Mini Plus is extremely compact, needs to be filled with water for every cup and the brewing operation takes just a bit longer because water must drain down and then be heated. The coffee flavor is just as good since you brew the same K-cups. If you're new to Keurig K-cup coffee or tea, you'll find it pretty comparable to coffee shop varieties, but much cheaper when you can enjoy that cup at home. Since operation varies slightly from the larger brewers, it's important to get the steps in the right order when using this personal Keurig, or you can add more time to get that hot cup of coffee or tea in your hand.
Turn it on, pour water in - that should match your cup size; add your cup or glass for iced/coffee or tea and lift handle to insert your K-cup. When the handle is raised, the water drains down where it is heated, then press Brew. That can take a few seconds, but it's really not that noticeable since you are adding your K-cup during that process. The Brew function changes from flashing to a constant red to show that the water is ready and brewing. You only need to press Brew once, it does the rest.
There's three choices for cup sizes but even with the drip tray removed, the unit does not accommodate a standard travel mug. The maximum cup or glass size is 5" tall (tray removed) - I wish it was just a shade taller. You could brew a second round and transfer that into a travel mug. If you love bold coffee, you'll like being able to make smaller cups. I prefer a medium flavor, so I used a short but stout mug for a 10 oz brew.
If you try and overfill the reservoir to 12 oz or so, the excess water will just end up in the drip tray, so that's not a good idea. I found it easy to either use the mug to measure and pour water or a measuring cup. The auto shut-off after 90 seconds can seem like a pain but with today's electricity rates, it's a big plus for saving energy. I really like this feature, just have everything ready to roll before you turn it on.
As with some other home Keurig brewers, the K-cup holder pops out easily so you can use the reusable Keurig My K-Cup filter assembly with your favorite coffee or tea blends. It works well, savings are tremendous and the flavor is much improved over using the same coffee with a regular coffee maker. Using that filter also allows you to cut down on coffee grounds if you prefer a lighter brew.
You can also use the Brew Over Ice K-Cup line with the Mini Plus to make iced coffee or tea. I used a 5" tall glass filled with ice (drip tray removed) and about 5 oz of water to brew. You might be able to use 6 oz of water if you lessen the ice; it depends on the shape of your glass and overall size. Nice to be able to make some iced beverages with this personal-size Keurig.
And if you want to save money on K-cups, you have to try the Keurig's My K-Cup Filter Assembly - a minute to fill the filter for a fraction of the coffee cost. Having the reusable filter choice is a big plus for Keurig brewers; no other brewer brand offers that (that I know of). We tend to brew the occasional 'treat' K-cup and use a My K-Cup Filter with Folgers™ coffee for a fantastic anytime brew. Guests of course always get the real K-Cup thing - their choice of flavor.
If being able to brew into your travel mug is a must, you're better off buying a larger Keurig with a 12 oz cup size option, because having to brew twice from the MINI Plus and transferring to the travel mug can be a drag.
The bottom line - same great coffee taste, just a smaller space-saving brewer. Less convenience when it comes to water filling, but easier to find a nook on the counter or elsewhere for it.
