Ninja Luxe Café Mini Espresso Machine: two-minute review

The Ninja Luxe Café Mini Espresso Machine is a compact version of the Ninja Luxe Café. It doesn't require an enormous amount of counter space, especially considering that this single machine grinds your whole beans directly into your filter, weighs your grinds, brews your espresso or drip coffee, and froths your milk. You won't need any other coffee accoutrements on your counter.

While I did brew some absolutely delicious coffee with the Ninja Luxe Café Mini, there is definitely a learning curve. In fact, I wouldn't say I have mastered the espresso settings yet, even after brewing many cups. Even with the identical espresso settings, sometimes I get just an ounce or so and sometimes I get a lot more. Drip coffee comes out consistently well; no issues there. I also had some trouble frothing the milk; with just a minimum amount of milk in the jug it overflowed onto the counter.

Note that even though this is a semi-auto machine, you do need to have some manual strength and dexterity to get the portafilter properly into place. Be ready for some trial and error. If you're prepared to take on a project, I think you'll be well-rewarded for your efforts.

Ninja Luxe Café Mini Espresso Machine: design

• Efficient design gives it a smaller footprint
• Aesthetically pleasing, goes with any decor
• Five brew styles

The Ninja Luxe Café Mini is efficiently designed to house everything you need to make just about any sort of coffee drink in a relatively small package. When you first unpack it, you will need to determine your water hardness with the enclosed test strip and set your machine accordingly. Run a flush cycle and then you're ready to start brewing.

The machine has a conical burr grinder, a brewing system that makes both espresso and coffee, and a steam wand. It comes with two filter baskets:, a smaller 'double' and a larger 'luxe' basket (unlike most espresso machines, there's no basket for pouring a single shot).

Place the basket into the portafilter, the funnel on top of that, and then slide it into the grinding cradle. Choose your brew style. The machine evaluates your beans and determines a recommended grind size. Turn the grind dial to meet the recommended number and hit the grind button.

Once your ground coffee is the basket, remove the portafilter and tamp down the grinds with the assisted tamper. It has a spring inside so you'll apply just the right amount of pressure.

Then you can remove the funnel, place the portafilter under the Ninja Luxe Café Mini's group head and turn it until it locks into place. This takes some manual strength and dexterity, and the machine's relatively light weight means you have to brace it in place so it doesn't slide around, though it does get easier with repeated use.

You can manually select your level of strength (represented by one, two, or three beans) and temperature or just use the default. When you're done brewing, dispose of the puck of used coffee grounds, and clean the dirty components.

There is also a milk jug and steam wand. To use it, turn the manual valve on the side from brewing mode to frothing mode. The owner's manual includes detailed instructions of how to get the most froth from your milk of choice.

You'll need to clean the tamper, funnel, basket, portafilter, steam wand and jug after each use. You'll also need to empty and clean out the drip tray every few brews, and every time you froth milk. Additionally, you'll need to descale the machine periodically. However, there is no obvious way to get in and clean the grinder. That part never gets wet, but coffee oils will build up there over time.

Ninja Luxe Café Mini Espresso Machine: performance

• There is definitely a learning curve
• You need manual strength and dexterity
• Brew amounts are not consistent

Overall, I think you'll find that the Ninja Luxe Café Mini will make you some great coffee and espresso drinks. There's definitely a learning curve, but if you have the patience you'll figure it out. Of bigger concern was that sometimes the brewing seemed to just stop short of a full yield, and I'm not sure why. The same beans brewed at the same setting just didn't always yield the same size espresso. This only happened to me while brewing espresso; all three of the drip coffee settings yielded perfect results every time.

There are five different brew settings: Espresso (which is actually a double espresso), Triple (espresso), Classic (drip coffee), Rich (a richer drip coffee), and Over Ice (drip coffee brewed at a lower temperature). I tested all five of them multiple times.

Espresso

The smallest drink you can make is a double espresso, there is no single espresso setting on this machine. The owner's manual says to throw away the first espresso you brew each time you put new beans into the hopper because it takes a couple of brews for the machine to dial in correctly. I tasted it anyway and yes, you should toss it. After that first one, the espresso tasted good though sometimes it would randomly give me a shorter brew. I did notice that I consistently got a beautiful crema.

Triple espresso

The experience of brewing the triple espresso is just like brewing the regular (double) one, only you use the Luxe basket instead of the smaller one. Again, the machine would sometimes give me a tiny brew. Pictured below is one of the smaller triples; other times it was much larger. Otherwise, the espresso was good and always had a lovely crema.

Classic

The Classic drip coffee setting yielded consistently good results. In addition to adjusting the grind size, brew temperature, and strength if you like, you can also choose to brew 6, 8, 10, or 12 ounces of coffee. The user experience of brewing the drip coffee is the same as brewing espresso, except that you skip the tamping step. The machine does something totally different on the inside. You get no crema. And when you go to throw the puck away, it's very wet, as opposed to the drier, crumbly puck you get with espresso.

Rich

The rich drip coffee setting works just like the classic, only it yields a richer brew. I find I prefer the classic, as I found it a bit smoother and less bitter, but your tastes may differ.

Over ice

The drip coffee over ice setting might have been my favorite. I found it very smooth and it didn't taste too diluted from the ice.

Steam wand

I found that it took some practice to get the milk frothing just right. I tried just leaving the jug in place and frothing it from there, and it works ok but doesn't produce much foam. I tried following the instructions about angle and movement in the owner's manual, and got too much foam.

The wand will purge itself right after frothing, and you'll want to wipe off the milk from the outside of the wand right away. Otherwise it sticks on there pretty good, requiring a bit of scrubbing to get it off.

• Performance score: 3.5/5

How I tested the Ninja Luxe Café Mini Espresso Machine

I brewed and drank every drink on the menu: (double) Espresso, Triple (espresso), Classic (coffee), Rich (coffee), and (coffee) Over Ice more than once. I used two different kinds of beans for each beverage, first going all the way through the menu with a dark french roast and then again with a medium-dark roast. I frothed two different kinds of milk (almond and skim dairy) several times and added the milk to espresso shots. I cleaned all of the parts that touch the coffee after each use.

First reviewed July 2026

If you love coffee, you’ll be very aware of the impact of factors like grind size, water temperature, and infusion time, but there’s something else that’s often overlooked. A double espresso is at least 90% water, and the minerals and other substances it contains can have a huge impact on the overall taste.

I’m a big coffee-drinker (which is just as well, since I test over a dozen coffee makers every year for TechRadar), and I’m planning to buy a water filter to take my brewing to the next level — but what should I look for — and what should you consider if you’re thinking of taking the plunge into filtered water too?

To find out, I spoke to Andy McPhilbin, Head of Aquaphor Professional for UK and Ireland, and Genevieve Upton, beverage industry expert and Head of Water Filtration at Our Taap.

Why does water matter?

“Water quality can have a considerable impact on how coffee tastes, with chlorine, mineral composition, alkalinity and pH all influencing the final flavour profile,” says Upton.

“Most tap water supplied to UK homes is disinfected using chlorine-based compounds. Residual chlorine can react with components in coffee and tea, contributing bitter, medicinal or chemical notes that may overwhelm the more delicate characteristics of the coffee. Boiling water can reduce the levels of chlorine, though it can also create other unwanted flavours, such as by reacting to a plastic kettle.”

She explains that the mineral composition and pH of the water also play an important role when it comes to how your coffee tastes.

“Slight differences in acidity, together with the concentrations of minerals and buffering compounds, influence extraction efficiency and the balance of flavors in the final cup. As water companies vary their supply sources throughout the year, you might notice that the same beans, brewed in exactly the same way, taste different from season to season.”

In fact, using unfiltered water doesn’t just mean your coffee tastes sub-optimal - it could cause your expensive coffee machine to break down — and it won’t be covered by the manufacturer's warranty..

“The warranty only covers manufacturing defects, and unfortunately, hard water is not a manufacturing defect,” explains McPhilbin. “So you can turn something that is a very efficient espresso machine into something very inefficient within a matter of weeks. You get a millimeter of scale forming within a matter of six weeks.

“Now, is that important? It is, because you want the life of the machine to be good, but also you've got little injectors which put the right amount of water into that espresso. If they're blocked, you're not going to get the right amount of water. You're going to have the wrong taste. It's got to be precise.”

What types of filtration are there?

Our Taap specializes in home water filtration Its latest system is the Our Taap Home Water System II — a countertop unit that connects to your mains water supply, and uses a triple filtration system with UV purification to remove contaminants while retaining minerals.

Aquaphor makes water filters for commercial and home use, including under-sink systems, pitchers, and even water bottles. Its most advanced systems for home users are the RO-101, RO-102, and RO-202, all of which use reverse osmosis (RO).

This involves forcing water through a semi-permeable membrane that removes chlorine, bacteria, viruses, pesticides, and microplastics. Standard RO filters also strip out minerals, but Aquaphor’s systems can optimize the concentration of calcium and magnesium so they’re just right for coffee — something McPhilbin says “really is a science”.

“The mineral content is measured in TDS [total dissolvable solids], and we want that TDS to be somewhere in the realms of between 80 and 120 [parts per million],” he explains. “We have a couple of ways in which we do it, but generally we can either feed more minerals in it by making it tuneable, or we can take them out as well by turning it the other way. But if you have too little, you can cause corrosion, and if we have too much, we're going to get limescale. So we try to hit that sweet spot, which is 100 parts per million in the middle there.”

Our Taap’s filters use granular activated carbon filtration, which Upton says “is particularly good at removing chlorine and some of its by-products, which can mask the more delicate flavour notes in coffee.”

“By reducing these compounds, the water has a cleaner, more neutral taste, allowing the natural characteristic of the coffee beans to come through. Whether you’re brewing with a cafetière, pour-over or espresso machine, using filtered water can help create a smoother, more balanced cup with greater flavour clarity.

"It's worth remembering, however, that activated carbon filters are designed primarily to remove chlorine and certain organic compounds rather than minerals,” she adds. “As a result, they have little effect on the calcium, magnesium and bicarbonate levels that influence water hardness, alkalinity and extraction.”

Under-sink or countertop?

So which type of filter is right for you? Do you need an under-sink reverse-osmosis system, or would a countertop filter be better? McPhilbin says the decision will mostly depend on how much filtered water you need.

“I think it's down to capacity more than anything,” he says. “Our jug filters have twice the capacity of the competition because we use a unique media called Aqualen, which is a patented media based on ionic exchange and carbon, so you're getting a dual-purpose piece of filtering equipment there. Reverse osmosis has a massive capacity, and [the filter] is not something [you’re] changing all the time.”

Upton says your choice of filter will also depend on the problem you want to solve.

“If your tap water has a noticeable chlorine taste or smell, a filter with activated carbon is usually the best place to start,” she says. “This technology is available in everything from filter jugs to more advanced under-sink or countertop systems, with plumbed-in options offering great convenience for households that use filtered water regularly.

“If you’re dealing with limescale build-up in kettles or coffee machines, it’s important to choose a filter that specifically reduces water hardness, as not all filtration systems are designed to do this.”

I know I live in a hard water area (the limescale in my kettle is proof) but even if your tap water is soft, McPhilbin says a water filter is still a good investment.

“Most of the water in the UK is chlorinated, and that can affect the taste quite a lot,” he says. “And it might be that you've not got enough minerals in it to get the best taste.”

If you’re not sure about the type of water you’re working with, there are online tools that can help you understand its composition.

“The Our Taap Water Confidence Index is a great way to look up your postcode and understand what’s in your local water and how this impacts taste, scent and quality, so you can find the best filter for your needs,” says Upton.

According to the Confidence Index, I’m lucky - my tap water is better than 93% of UK postcodes. However, it is moderately hard (as I expected), with a normal level of chlorine and an elevated level of overall minerals. I’m still deciding exactly which type of filter to choose, but considering these results and my penchant for espresso, I’m leaning towards under-counter reserve osmosis with mineral balancing.
