Best Coffee Beans for the Ninja Luxe Café: Espresso Mode, Filter Mode, and Everything In Between

The Ninja Luxe Café is an assisted semi-automatic machine with a 58mm portafilter, a built-in conical steel burr grinder, and an integrated scale that weighs the dose before every extraction. It also has a second brewing mode, the Luxe Basket, which switches the extraction method from 9-bar espresso pressure to a low-pressure gravity-style drip.

The Ninja Luxe Café requires the user to dose, tamp, and lock the portafilter. In return, it produces both authentic espresso and proper filter coffee from the same machine.

That dual capability changes how bean choice works. A medium-dark blend with a dry surface and good crema production suits espresso mode well.

The same bean in the Luxe Basket for filter coffee can taste flat. A lighter single origin that performs well in filter mode will often produce a thin, underextracted shot in the portafilter.

Short answer: 

• The best Caffé Prima bean for espresso mode is the Espresso Blend: a medium roast with low surface oil that protects the narrow dispensing chute and extracts consistently at 9 bar.
• For filter mode via the Luxe Basket, the 100% Colombian is the top pick. 

This guide covers both modes, the grind settings for each, and which beans to avoid.

How does the Ninja Luxe Café extract espresso and filter coffee differently?

The machine operates through two physically distinct extraction methods, both using the same grinder but different baskets and different pump profiles.

In espresso mode, the machine uses single or double espresso baskets in the portafilter. The pump generates up to 15 bar of internal pressure, regulated down to 9 bar at the coffee puck. A pre-infusion phase wets the coffee bed gently before full pressure ramps up, which improves extraction evenness.

The built-in scale weighs the dose before grinding:

• 9g for the single basket
• 18g for the double

The grind setting for espresso should sit between 5 and 9 on the 25-step dial.

In filter mode, the machine uses the deep Luxe Basket. When the machine detects this basket, the extraction switches from 9-bar pressure to low-pressure pulsed water flow, which mimics a gravity drip machine. The basket is filled with grounds at a coarser grind of 22 to 25 on the dial. The grounds are levelled but not tamped. For a 10oz cup, the scale targets approximately 27g of coffee.

The grinder routes beans through the same conical steel burrs regardless of mode. The difference is the dial position and the dose weight, both of which the machine adjusts automatically through the Barista Assist system.

Treat Barista Assist as a starting recommendation rather than a fixed instruction: the system can go into a feedback loop if bean type, freshness, or tamping consistency changes, and experienced users find better results by manually selecting a fixed grind setting and resetting the Barista Assist memory (via _h04 in the settings menu) when switching bean types.

Which Caffé Prima beans work best in espresso mode?

The espresso mode on the Ninja Luxe Café rewards medium to medium-dark roasts with a dry surface and low-to-moderate oil content. The grinder's steel burrs and the narrow dispensing chute are susceptible to oil build-up from heavily oiled dark roasts, which causes grounds to stick to the chute walls and eventually triggers dosing errors or grinder stalls. The five beans below suit espresso mode on this machine.

1. Espresso Blend: the headline recommendation for espresso mode

The Caffé Prima Espresso Blend is the best all-round bean for the Ninja Luxe Café in espresso mode. It is a medium roast of Brazilian and Guatemalan Arabica with Vietnamese Robusta, which keeps the surface oil low. Low oil content reduces residue in the dispensing chute and keeps the 25-step burr grinder running cleanly between cleans.

The flavour profile is dark chocolate and nutty with balanced acidity. It extracts well at the machine's default medium brew temperature and produces consistent results on Strength 2 (1:2.5 ratio, approximately 45g yield from the double basket) and Strength 3 (ristretto-style, 1:2 ratio, approximately 36g yield).

Start at grind setting 7 and adjust from there. If the shot runs through in under 20 seconds and tastes sour, move one step finer. If extraction takes more than 35 seconds or the cup tastes bitter, move one step coarser.

2. Continental Blend: the everyday choice for milk drinks

The Caffé Prima Continental Blend is a medium-dark blend of Brazilian Arabica and Vietnamese Robusta with a dark cocoa and hazelnut flavour. Its Robusta content generates rich, persistent crema that lasts four to five minutes in the cup. On the Ninja Luxe Café, that crema quality matters particularly in milk drinks: the machine's automated steam wand does the frothing work, but the espresso layer needs to carry its own character through the milk.

Continental runs cleanly through the portafilter on grind settings 6 to 8. Set the brew temperature to Low (the machine's lowest of three settings) for a smooth, balanced extraction. Use Strength 3 for flat whites and cappuccinos where a concentrated ristretto base holds up through milk better than a longer pour. 

3. Italian Mahogany: the most forgiving starter

Caffé Prima Italian Mahogany is a dark roast with cinder toffee and cocoa flavour notes, very low acidity, and thick persistent crema. It is the best-selling bean in the range and the most forgiving to extract: it produces a good shot with less grind precision than lighter roasts require, making it the right starting point for new owners still learning the portafilter workflow.

The trade-off on the Ninja Luxe Café is grinder maintenance. Italian Mahogany is a dark roast and develops some surface oil. The dispensing chute on this machine is narrow, and oil from dark roasts accumulates faster here than in a traditional bean-to-cup machine with a sealed internal grinding path. If Italian Mahogany is the main bean in the hopper, clean the accessible burr ring and brush out the chute weekly. Set the brew temperature to Low and use grind settings 5 to 7.

4. Decaffeinated Brazilian Arabica: the afternoon and evening option

The Caffé Prima Decaffeinated Brazilian Arabica is decaffeinated by the CO2 process, a chemical-free method that removes 99.9% of the caffeine while preserving the bean's milk chocolate and silky body character. 

It runs on the Ninja Luxe Café with the same grind settings and brew temperature as the Espresso Blend: settings 7 to 9, medium brew temperature. The low oil content keeps the grinder clean. 

5. 100% Colombian: the upgrade for confident users

The Caffé Prima 100% Colombian is a single-origin mountain-grown Arabica with caramel, hazelnut, and almond flavour notes. It is a medium roast, which means it is harder to extract cleanly at a fixed brew temperature than medium-dark blends.

On the Ninja Luxe Café, use the Colombian at medium brew temperature, grind settings 8 to 10, and Strength 2 (the standard 1:2.5 ratio). The longer ratio suits this bean better than the ristretto Strength 3, which can emphasise its acidity. Colombian is the bean to move to once the machine is calibrated and the portafilter workflow is consistent. 

Which Caffé Prima beans work best in filter mode?

The Luxe Basket changes the extraction entirely. Without pressure and without tamping, the brewing relies on water flowing through a larger, coarser coffee bed under gravity. Lighter and medium roasts perform much better here than in espresso mode: they dissolve cleanly at lower pressure, and their brighter notes come through in the cup rather than being masked by extraction force.

1. 100% Colombian: the top pick for filter mode

The Caffé Prima 100% Colombian is the standout Caffé Prima bean for filter mode on the Ninja Luxe Café. The caramel and hazelnut notes that can feel tight in a ristretto espresso open up cleanly in a gravity extraction. Set the grind to 22 to 24, use the medium brew temperature, and select Strength 2 for a balanced 10oz cup. The result is a substantial, full-bodied filter coffee that bears no resemblance to the thin drip coffee most people associate with domestic filter machines.

2. Brazilian 100% Arabica: the everyday filter option

Caffé Prima Brazilian 100% Arabica is a light roast with almond and chocolate flavour notes, low acidity, and a smooth, mild body. It is not recommended as the primary espresso bean on this machine: the light roast requires more extraction energy than the portafilter at fixed temperature can reliably deliver. In filter mode through the Luxe Basket, however, it works very well. The gravity extraction is gentler and suits the bean's structure.

Use grind settings 23 to 25, medium brew temperature, and Strength 2. For drinkers who find darker roasts too heavy at breakfast, the Brazilian in filter mode gives a clean, easy-drinking cup. It costs £13.79 per 1kg or £74.99 for the 6kg case.

3. Roma: filter mode brings out the citrus notes

Caffé Prima Roma is a medium roast of Brazilian, Honduran, and Vietnamese beans with citrus and nutty notes. It works in espresso mode on this machine but performs better in filter mode, where the citrus character has more room to develop. Use grind settings 22 to 24 and medium brew temperature. Roma is a good option for households where one person wants espresso and another wants a longer, brighter filter coffee: the bean handles both modes without being the best choice for either.

What grind settings should you use on the Ninja Luxe Café?

The dial runs from 1 (finest) to 25 (coarsest). A broadly reliable starting framework is grind settings 5 to 9 for espresso mode and 22 to 25 for filter mode. Within espresso, medium roasts sit at the coarser end of that range and dark roasts sit at the finer end.

The machine's Barista Assist technology reads the flow rate from the previous shot and suggests a grind adjustment. The suggestions are useful as a rough guide, but the algorithm can drift if the bean type, roast date, or tamping pressure changes. When switching beans, reset the Barista Assist memory by holding the settings button and navigating to _h04. This clears the previous feedback data and lets the new bean dial in from a neutral starting point.

An extraction time of 25 to 32 seconds for a double espresso shot is the target range on this machine. If the shot produces only 10 to 15ml of liquid rather than the expected 36 to 45ml, the grind is too fine and the machine's overpressure valve is redirecting water to the drip tray. Move one step coarser.

How does the strength selector change which bean to use?

In espresso mode, the strength selector does not change how much coffee is ground. The dose is fixed at 18g for the double basket. The selector changes the volume of water pumped through the puck, which changes the brew ratio and the character of the shot.

Strength 3 produces a ristretto-style extraction at a 1:2 ratio (approximately 36g of liquid from 18g of grounds). It suits medium-dark and dark roasts, where a concentrated ratio amplifies the chocolate and caramel notes without over-extracting bitterness. Continental and Italian Mahogany both perform better on Strength 3 for milk drinks.

Strength 2 produces the standard espresso ratio of 1:2.5 (approximately 45g of liquid). It suits medium roasts like the Colombian and the Espresso Blend, where the longer ratio gives the bean's sweeter notes space to develop.

Strength 1 produces a lungo-style extraction at a 1:3.5 to 1:4 ratio (approximately 63 to 72g of liquid). This is the setting for an Americano-style drink, where additional hot water from the machine's dedicated hot water outlet will be added after the shot.

In filter mode, the strength selector works differently. It adjusts the dry dose weight, not the water volume. A higher strength setting means more ground coffee goes into the Luxe Basket, which increases the concentration of the brew. Increase strength in filter mode if the cup tastes weak or thin. Reduce it if the brew backs up in the basket rather than flowing through cleanly.

Can you use dark roast beans in the Ninja Luxe Café?

Dry-surface dark roasts work on this machine. Italian Mahogany is a dry dark roast: it has a darkened surface without the heavy oil sheen of traditional Italian espresso beans, and it runs through the portafilter reliably with weekly grinder cleaning.

Visibly oily or glossy dark roast beans cause two problems specific to the Ninja Luxe Café's design.

First, the oil binds fine coffee particles to the walls of the dispensing chute, building a physical blockage that prevents grounds from dropping into the basket. The grinder motor runs but the dose weight on the scale does not increase, and the machine either aborts the cycle or produces an underdosed shot.

Second, if the build-up reaches the burr carrier, the motor can stall under the increased friction. 

If the machine is producing dosing errors or the grinder sounds laboured, stop using the current bean, vacuum out the hopper, brush out the dispensing chute, and switch to a lower-oil bean like the Espresso Blend or the Decaf Brazilian Arabica.

Frequently Asked Questions

Which Caffé Prima bean is best for the Ninja Luxe Café?
For espresso mode, the Caffé Prima Espresso Blend at £11.99 per 1kg is the most reliable starting point. Its low oil content protects the grinder, and it extracts consistently on grind settings 7 to 9 at medium brew temperature. For filter mode via the Luxe Basket, the 100% Colombian at £14.99 per 1kg gives the clearest, most satisfying result.

What grind setting should I start on for espresso?
Start at grind setting 7 for medium or medium-dark roasts. Adjust by single steps while watching extraction time: 25 to 32 seconds is the target. Change the grind setting while the grinder is idle and wait for the next shot to assess the result.

What grind setting should I use for filter coffee in the Luxe Basket?
Start at grind setting 22 to 24. The Luxe Basket uses a coarser grind and does not require tamping. Level the grounds with a gentle side-to-side shake of the portafilter before brewing.

What does the strength selector do in espresso mode?
The strength selector changes the brew ratio by adjusting the volume of water pumped through a fixed 18g dose. Strength 3 produces a ristretto-style shot at 1:2 ratio (approximately 36g of liquid), suited to dark and medium-dark roasts in milk drinks. Strength 2 produces a standard 1:2.5 ratio (approximately 45g), suited to medium single origins drunk black.

Why is my espresso shot producing very little liquid?
A very small yield (10 to 15ml rather than 36 to 45ml) means the grind is too fine and the machine's overpressure valve is releasing pressure rather than pushing water through the puck. Move the grind dial one step coarser and re-pull the shot.

Can I use oily dark roast beans in the Ninja Luxe Café?
Dry-surface dark roasts work with weekly grinder cleaning. Visibly oily or glossy beans cause chute blockages and grinder stalls on this machine. If you want to use a darker roast, choose Italian Mahogany over heavily oiled traditional Italian beans, and clean the dispensing chute weekly with a stiff brush.

How fresh should the beans be?
Between two and eight weeks from the roast date. Beans under seven days old contain elevated CO2 that causes uneven extraction in the pre-infusion phase. Beans over eight weeks old produce flat, weak coffee regardless of grind setting. Caffé Prima beans are roasted to our recipes, low and slow, in small batches in the UK and you usually get them within 4 weeks from roast to delivery and same-day dispatch for orders placed before 3pm.

Is the Ninja Luxe Café the same as a bean-to-cup machine?
No. The Ninja Luxe Café requires the user to dose, tamp, and lock the portafilter for espresso mode. A fully automatic bean-to-cup machine like the Philips 5500 LatteGo or the De'Longhi Magnifica Evo handles all of those steps internally. The Ninja Luxe Café is closer to a semi-automatic espresso machine with automated dosing and milk frothing than it is to a super-automatic machine.
