Based on a review by Cafelista (accessed 2026-06-15).
Based on this review alone: buy it if you care about produces larger coffee pucks (up to 21g for triple shot) — just accept first machine startup caused the grinder to run empty, requiring a restart.
The reviewer concludes that the Ninja Auto Barista Pro, while not producing a traditional short, dense espresso like a manual machine, offers richer and more concentrated coffee than typical automatics due to its larger doses. The milk frothing system produces good texture but can overheat milk, and the innovative Grind IQ system, while promising, can be slow and wasteful during calibration, making it somewhat imperfect in execution.
This review provides a comprehensive test of the Ninja Auto Barista Pro, an automatic bean-to-cup coffee machine. The reviewer, Colin from Cafelista, examines its innovative features, including a new brew group for larger coffee pucks, a fine conical grinder, an integrated scale, and a dual interchangeable bean hopper system. He conducts objective measurements on espresso extraction (dose, ratio, TDS) and milk frothing temperature.
The Ninja Auto Barista Pro delivers a richer, more concentrated espresso compared to most automatic machines, making it a strong contender for its category. It achieves this with an impressive 21g coffee dose for its triple shot, significantly more material than competitors, and a uniquely clean chamber with almost no retention. However, the Grind IQ calibration process can be inconsistent and consume a substantial amount of coffee for testing. If you prioritize a more robust, espresso-like coffee from an automatic machine and are willing to manage some initial calibration quirks, this machine is a good choice. If you seek a simple, no-fuss experience from day one without sacrificing coffee, you might want to consider alternatives.

The Ninja Auto Barista Pro makes larger coffee pucks than its competitors, thanks to a new, different extraction group.
reviewer_claimpositivet=00:22–00:24
The machine grinds coffee much finer than other machines, addressing a common criticism of automatic coffee makers.
reviewer_claimpositivet=00:24–00:26
The machine froths milk using a true steam wand, rather than a closed carafe system.
measurement_testpositivet=04:05–04:10
The reviewer measured the largest dose at 20g, which is significantly more than most automatic machines that typically dose between 7 to 12g.
specification_claimneutralt=04:24–04:28
The machine features a conical grinder with 50 automatic adjustment positions, offering a wide range of grind fineness.
specification_claimneutralt=04:31–04:33
An integrated scale weighs the coffee to the nearest gram every time, ensuring precise dosing.
specification_claimneutralt=04:36–04:39
The machine includes a double interchangeable bean hopper system, each holding 340g, allowing users to switch between different coffee types easily.
specification_claimneutralt=05:07–05:11
The machine offers a wide range of beverages including espresso, filter coffee, cold brew, and cold foam, demonstrating its versatility.
specification_claimneutralt=05:17–05:20
The machine is priced at 900 euros in Europe and 950 dollars in the United States.
measurement_testnegativet=09:12–09:18
At intensity 1, the machine produced approximately 10g of coffee, nearly 50g in the cup, with a TDS of 3.4%, which is very light and diluted, more akin to a long coffee.
measurement_testpositivet=09:40–09:47
At intensity 2, the machine delivered around 16g of coffee with 50g in the cup, resulting in a long ratio (1:3) but a TDS of 7.17%, which is considered serious for an automatic machine.
measurement_testmixedt=10:13–10:18
At intensity 3, the machine produced almost 21g of coffee, 68g in the cup, with a TDS of 8%. This concentration is typical for espresso, but the shot was very elongated, making it too long.
comparisonpositivet=11:00–11:08
The Ninja produces espresso with significantly more body and concentration than classic automatic machines, making it richer than average compared to competitors.
hands_on_demonegativet=13:39–14:10
During the first startup, the grinder ran empty for a long time, requiring a restart. The Grind IQ also consumed a lot of coffee, needing 5 to 7 shots for calibration instead of the expected 2-3, potentially wasting expensive specialty coffee.
measurement_testnegativet=16:47–16:51
At its maximum setting, the milk temperature exceeded 80 degrees Celsius, which the reviewer found to be too hot for optimal taste.
The reviewer's measurements indicate that while the espresso shots can be quite long, the machine uses significantly more coffee (up to 21g), resulting in higher TDS values (up to 8%) compared to typical automatic machines (6-8%). This leads to a richer, more concentrated beverage, even if it deviates from a traditional short espresso shot.
The machine features a genuine steam wand with a thermal probe and a motorized whisk in the pitcher, offering 5 foam styles, including cold foam. This system creates a finer, more textured microfoam than fully automated carafe systems. However, the maximum temperature setting heats the milk to over 80 degrees Celsius, which the reviewer finds too hot for optimal taste.
Priced at 900 euros, the machine is positioned against high-end automatic competitors. Its unique features, such as the integrated scale, dual interchangeable bean hopper, and the potential for larger coffee doses and finer grind, differentiate it. However, practical issues like the Grind IQ's coffee waste and the milk system's high temperature at max settings need to be weighed against its cost. The reviewer implies its value depends on how much a buyer prioritizes these specific innovations.
The Grind IQ aims to automatically adjust grind finesse and dosage by analyzing the first few shots with new coffee. While the concept is excellent for simplifying initial setup, the reviewer experienced the grinder running empty on first startup, and noted that it often required 5-7 shots (rather than the advertised 2-3) to calibrate, potentially wasting a significant amount of specialty coffee. Manual adjustment is also cumbersome.
The machine features two 340g interchangeable bean hoppers. This, combined with its unique dosing mechanism that doesn't store beans in the chamber, results in virtually no retention. This innovative design allows users to rapidly switch between different coffee types, such as decaf or different roasts, without the need to purge the system, a feature the reviewer describes as unique and highly convenient.
100/100 source quality
The Ninja Auto Barista Pro is an ambitious automatic coffee machine featuring larger coffee pucks, a very fine grinder, an integrated scale, and a unique dual bean hopper. The reviewer performs detailed measurements of espresso intensity and concentration (TDS), finding the machine delivers richer coffee than many competitors, though often in longer shot volumes. He also evaluates the true steam wand for milk frothing, noting excellent texture but potential for overheating, and critically assesses the Grind IQ automatic calibration system, highlighting its potential for coffee waste during initial setup. The machine was loaned by Ninja, but the review is presented as independent.
