In this comprehensive guide, we’ll share our hands-on experience with the best coffee scales available today. We’ll explain why dedicated coffee scales outperform standard kitchen scales, break down the significant price differences (from £10 to £200+), and help you understand exactly what you’re paying for.
For filter coffee, our measurements indicate that 60-65 grams of ground coffee is ideal for brewing 1 litre of perfectly balanced coffee.
Here’s what our testing revealed about common measuring mistakes: Using scoops or spoons is remarkably unreliable. Coffee beans are surprisingly light, and their weight varies significantly. Through our lab testing, we’ve found that individual beans typically weigh between 0.1 and 0.15 grams. This variation means that even three seemingly identical scoops can result in notably different amounts of coffee.
Our research uncovered another crucial factor: scoop sizes aren’t standardised. Some hold 5 grams, others 7 grams, and speciality tools like the Aeropress scoop contain around 17-18 grams. This inconsistency makes reliable measurement impossible without proper scales.
We’ve also discovered through testing that roast levels affect bean weight significantly. Darker roasts are consistently lighter than their lighter-roasted counterparts. When you combine these variables, it becomes clear why eyeballing or using scoops leads to inconsistent coffee quality.
Using precise scales eliminates these variables entirely, ensuring each cup matches your previous best brew. Without them, you’re leaving your coffee quality to chance.
Here’s what our professional testing has revealed about the key features that separate specialist coffee scales from standard kitchen models.
Through years of testing and daily use, we’ve identified accuracy as the primary factor in determining a coffee scale’s price point and effectiveness.
The precision level varies significantly across price ranges. Basic digital scales measure to the nearest gram, while professional models can measure to 0.1 grams, and laboratory-grade scales reach 0.01-gram precision.
Based on our extensive testing, we’ve found that 0.01-gram precision is unnecessary for coffee brewing. These ultra-precise scales are better suited for jewellery and precious stones.
For home coffee brewing, our experience shows that you rarely need to weigh more than 100-200 grams at once. We recommend focusing on scales that offer 0.1-gram increments within this range.
For espresso, you’ll typically weigh around 20 grams of coffee, while filter coffee requires 60-65 grams for a litre of filter coffee.
Our testing reveals that scales offering 0.1-gram increments up to 200 grams, then switching to 1-gram increments for higher weights, provide the ideal balance of precision and value. While premium scales maintain finer precision at higher weights, this feature isn’t essential for most coffee enthusiasts.
Remember, though: even perfect measurements can’t compensate for poor-quality beans. For guidance on selecting excellent coffee, we recommend reading:
Time and weight work together as the foundation of exceptional coffee brewing.
While standard kitchen scales focus solely on weight measurement, dedicated coffee scales integrate crucial timing functions.
As professional baristas, we know that brewing time significantly impacts flavour extraction, whether you’re crafting pour-over coffee or pulling the perfect espresso shot.
Yes, you could juggle your mobile phone’s stopwatch while watching your coffee’s weight, but our testing shows this often leads to inconsistent results and spilled coffee.
Having an integrated timer transforms the brewing process, allowing you to focus entirely on creating your perfect cup.
When we talk about response time, we’re discussing how quickly your scales register weight changes.
This might seem like a minor detail, but our extensive testing proves it’s crucial for precision brewing.
For espresso particularly, slow response time can mean the difference between a perfectly balanced shot and one that’s over-extracted.
With lower-quality scales, the delay between actual weight and displayed weight means you might be adding several extra millilitres to your shot before you’ve even realised it.
Unlike kitchen scales that might see occasional use during weekend baking sessions, coffee scales become part of your daily ritual.
Our team’s experience shows that battery-powered scales can become a genuine hassle when you’re brewing multiple times daily.
There’s nothing worse than preparing for your morning coffee only to discover dead batteries – and we’ve all been there!
While rechargeable batteries offer one solution, we’ve found that built-in rechargeable systems provide the most convenient and environmentally conscious option.
In our testing, we’ve noticed that budget-friendly scales typically rely on replaceable batteries, while mid-range and premium models feature integrated charging systems.
Battery life varies significantly between models.
Generally, our research shows that premium scales offer longer battery life between charges.
Charging ports matter too – we’ve found USB-C ports, common in modern Android phones, to be particularly practical.
The coffee scale market spans from basic £10-£20 models to sophisticated options exceeding £200.
Here’s what our testing reveals about budget scales:
However, we recognise that these limitations might not matter to everyone.
For casual brewers using manual methods who don’t mind slower response times and simpler features, budget scales can serve perfectly well.
Amazon’s generous return policy also helps mitigate the risk of getting a faulty unit.
When you invest a bit more (typically £30-£50), our testing shows you gain:
But what about premium scales? Why might someone invest £100 or more? Our professional testing reveals these advantages:
The right choice depends entirely on your brewing style and needs.
Take our team’s experience: while we appreciate the features of premium scales like the Felicita Arc and Acaia Lunar (reviewed below), many of us are perfectly satisfied with mid-range options like the Timemore Black Mirror, which we’ll discuss in detail.
However, for dedicated home baristas craving precise data and instant response times, premium scales become a worthwhile investment.
Meanwhile, casual coffee enthusiasts might find complete satisfaction with simpler, more affordable options.
Through our hands-on testing, we’ve found these scales represent solid value for manual brewing methods. While they might not win any precision awards, they deliver reliable performance for their price point. We specifically tested these scales with various pour-over methods, and they proved competent for basic coffee measurement needs.
The price point makes them incredibly accessible for coffee enthusiasts just starting their brewing journey.
We appreciate their straightforward, no-nonsense operation that doesn’t require a manual to understand.
During our testing, we noticed some consistent quirks. The scales typically show an initial reading between 0.4-0.6g when powered on, requiring a quick tare before use.
Response time isn’t particularly snappy, which we expected at this price point.
Our research into user experiences reveals mixed long-term reliability, though Amazon’s return policy offers peace of mind if issues arise.
In comparing these scales directly with the Coffee Gator model below, we noticed striking similarities in design and functionality. Whether this indicates shared manufacturing or design inspiration remains unclear, but their performance characteristics align closely.
Our team found these scales offer excellent value, pricing even lower than the Coffee Gator alternative.
The generous capacity matches pricier competitors, with claimed sensitivity that looks good on paper.
While marketed as 0.1g sensitive, our practical tests showed less precise measurements than advertised.
We observed occasional weight fluctuations, similar to those seen with the Coffee Gator scales. This reinforces our view that certain compromises come with budget-friendly options.
Coffee Gator has built a solid reputation in the coffee accessories market, particularly with their storage solutions. Their gooseneck kettle shows similar attention to detail, and these scales follow suit. In our comparison with the Hario scales discussed below, we found several parallel features, including battery power and timer functionality.
The 3kg capacity surpasses most competitors, though our testing suggests this might be overkill for typical brewing needs.
We found the price point particularly attractive, offering good value at roughly half the cost of Hario’s offering.
Our testing revealed response lag similar to other budget options, which proved more problematic for espresso than filter coffee brewing.
We experienced occasional weight inconsistencies, particularly when removing and replacing brewers. Some measurements jumped by several grams, requiring extra tare operations.
Having extensively tested various scales in our collection, including the Brewista Smart Scale 2 and My Weigh Barista, the Timemore Black Mirror has genuinely impressed our team. The practical advantages became clear through daily use.
The scales maintain charge impressively well, power up instantly, and deliver consistent precision. We particularly value the auto-timer function for brew consistency. Their size and form factor proved especially practical for espresso brewing.
The minimalist design caught our attention – the matt black surface conceals the display until activated, creating an striking aesthetic. The only visible feature is the charging port, which also serves as a reference point for the power button location.
Operation couldn’t be simpler: power on, tare, start timer, and brew. The auto-timer function engages with eight quick presses, displaying ‘A’, then counting down from three before entering ready mode.
USB-C charging offers modern convenience, using the same cables as contemporary Android phones and other devices.
Our testing confirmed excellent precision and responsiveness.
The width accommodates portafilters comfortably.
Auto-timer functionality enhances brewing consistency.
Sleek design matches modern kitchen aesthetics.
Decent water resistance protects against coffee spills.
The chunky profile may create clearance issues with some espresso machines’ portafilters. While compatible with most Sage or Breville machines, it’s a tighter fit with the Gaggia Classic. A bottomless portafilter or low-level drip tray can help.
The exposed charging port seems an oversight in water resistance design. We recommend purchasing these USB type C charging port covers for added protection.
Occasional sensitivity to knocks can cause small reading variations, requiring additional taring.
As specialists in pour-over brewing, we’ve found these scales particularly suited to Hario V60 brewing. They share key specifications with the Timemore Black Mirror, including weight range and sensitivity, but lack auto-timing functionality.
Dimensionally, they’re slightly deeper than the Timemore but narrower and marginally taller.
Straightforward operation with essential timing and auto-off features impressed our team.
The generous surface area easily accommodates larger brewing vessels.
Battery dependency proves less convenient than rechargeable alternatives, though rechargeable AAAs offer a workable solution.
Response lag of approximately one second might frustrate espresso brewing, though it’s less problematic for pour-over methods.
Accuracy decreases with larger weights: 0.1g increments to 500g, then 0.5g to 1kg, and 1g increments to 2kg.
Limited water resistance makes them vulnerable to brewing mishaps.
During our extensive testing period with the Brewista Smart Scale II, we discovered both brilliant features and notable limitations.
As coffee professionals who’ve tested countless pieces of equipment, we appreciate Brewista’s reputation for quality. Their Artisan gooseneck kettle remains a favourite in our test kitchen, which initially sparked our interest in these scales.
When comparing it to the Timemore Black Mirror, we found the Brewista offers similar precision but in a more compact package. This smaller footprint proved particularly useful when working with various espresso machines, fitting neatly under most portafilters.
The battery performance surprised us. Despite its seemingly modest 1000 mAh capacity, we only needed to charge it two or three times throughout our testing period—outlasting even the Timemore Black Mirror.
What sets these scales apart is their comprehensive range of user modes:
The height strikes an excellent balance, accommodating more espresso machines than bulkier alternatives.
The variety of user modes caters to different brewing styles and preferences, making it versatile for various coffee preparation methods.
The compact design occasionally presents challenges with portafilter placement, though this isn’t unique to Brewista—many premium scales share this characteristic. A portafilter stand readily solves this minor issue.
Switching between modes proved more complicated than necessary. Once you’ve found your preferred setting, you’ll likely stick with it rather than navigate the somewhat frustrating mode-changing process.
Our biggest concern emerged regarding water resistance. Despite claims about “water-resistant nano coating” and positive reviews elsewhere, our unit suffered from moisture damage. After a minor spill and proper wiping, the scale began showing erratic readings, continuously increasing without stabilising. Even after following the manual’s guidance about drying time, the issue persisted months later.
We should note that our experience with water damage might be an outlier, as most user reviews praise the scale’s water resistance. We’re considering acquiring another unit for further testing.
You can see these scales in action in our Gaggia Ruby review:
Moving into the mid-range category, we’ve thoroughly tested these scales as a replacement for our previous Brewista unit. After two years of intensive use, we can confidently speak to their durability and reliability.

The chunky profile matches the Timemore Black Mirror’s thickness, which may present fitting challenges with certain espresso machines. While most Sage machines accommodate these scales well, some setups like the Gaggia Classic Pro might require modifications such as a low-profile drip tray or naked portafilter.
The auto-stop feature, while useful when it works, shows occasional inconsistency.
The lack of an auto-timer function might disappoint brewers seeking this specific feature.
Felicita, based in Japan, has established itself as a premium manufacturer of coffee equipment, specialising primarily in scales while also producing a temperature-controlled kettle.

Watch the Lunar in action:
After months of testing, we’ve found coffee scales span a broad spectrum, from budget-friendly basics to professional-grade equipment that might require a moment to catch your breath at the price tag.
For most home enthusiasts, we recommend focusing on the mid-range options we’ve covered.
However, if you’re just starting your coffee journey and need basic dose and brew weight measurements under £20, the entry-level options will serve you well.
For professional baristas and dedicated enthusiasts who’ll benefit from advanced features, the premium options justify their investment through durability and precision.
Standard digital kitchen scales can work for basic coffee measurements, but they often lack the precision and features that enhance coffee brewing.
Dedicated coffee scales offering 0.1g precision and built-in timers significantly improve brewing consistency.
When you’re working with speciality coffee beans, we strongly recommend investing at least £20 in proper coffee scales – it’s a small price to pay for getting the most from your premium beans.
Perfect coffee requires precision, and our extensive testing reveals that coffee scales are essential for consistently outstanding brews.
Using scales might seem like overkill if you’re accustomed to eyeballing your measurements.
However, our barista team discovered that precise measurements dramatically improve your coffee, regardless of brewing method.
For French press brewing, we’ve found that a ratio of 15g coffee to 250ml water (perfect for a standard mug) produces remarkable results.
Gone are the days of approximate spoonfuls – measuring transforms your cafetiere experience entirely.
