There are many factors that go into brewing a perfect cup of coffee. Finding an ideal ratio between water to coffee grounds is one of those factors.
While it’s easy to eyeball the amount of coffee needed, a precise measurement can be the very thing that takes your coffee to the next level. A quality coffee scale is a great brewing tool to have at home, especially for users who crave consistency.
Whether you’re looking to experiment with different ratios, or you’re looking to reproduce a recipe that works with your brew method and bean selection, a scale will help you stay on track.
With so many scales available to choose from, it can be difficult and overwhelming to find one that works best for your brewing style, machine type, and personal preferences. We’ve compiled a list of some of our favourite coffee scales on the market in order to help make your scale search easier.

The Hario drip scale includes a built-in timer to help users follow and repeat brew recipes. This device weighs in both 1 gram and 1/10th of a gram measurement for desired precision.

With a water-resistant nano-coating and completely sealed body, the Brewista smart scale can be kept on a drip tray.

Upgrade Pick: Acaia Pearl Brewing Scale
Similar to the Acaia Lunar coffee scale, the Acaia Pearl coffee scale is tailored to excel for coffee enthusiasts and coffee brewing professionals alike. This durable and modern design packs many of the favoured features from the Lunar model, with added features to increase the precision in weighing coffee.
The Acaia Pearl comes with a real-time flow rate indicator that visualizes user pouring speed and suggests thresholds for ideal pour overflow rates. Users can also select from six weighing modes including dual display mode, auto-start timer mode, auto-tare, espresso, and beverage mode.

For users only brewing one cup of coffee daily, this scale will need to be charged every few months, offering a greener alternative to most scales.
While the Pear provides both precision and quality, the steep price makes it intimidating for entry-level users. Its dimensions run too tall to be placed under the portafilters of many espresso machines, which can be problematic for some users. Furthermore, its primarily plastic body isn’t as heat-resistant as other scales. This scale is not waterproof.

Coffee Scale Buying Guide
Coffee scales are great tools for enthusiasts looking to master the production of a perfect cup. Unlike other brewing devices and coffee makers, scales are more affordable, too. However, it’s important to find the right quality and features in a coffee scale to meet your needs.
With the wide variety of kitchen scales available, it can be difficult to determine the perfect investment for your preferences. We’ve assembled this buying guide to include helpful considerations to narrow the coffee scale search.
Coffee Brewing Style
Whether you’re primarily a pour-over coffee brewer or are brewing coffee with an espresso machine, you need a coffee scale with the precision to match your weighing needs.
Certain coffee scales are suitable for manual brew methods, while others work best for weighing for an espresso machine. Higher-end scales include additional modes for pour-over methods and espresso, which provide users with options for manual or automated timing and taring. The sizing of the scale will also factor into the brew method compatibility. Scales with larger dimensions may be great for manual brewing, but not sufficient to fit on the drip tray or under the portafilter.
Since a scale’s primary job description is to provide accurate weight measurements, it’s important to purchase a scale that will provide consistent results. With coffee beans being fairly light, a quality coffee scale needs to be precise to 0.1 of a gram. If a brewing scale is only accurate to the half or whole gram, users won’t be able to consistently measure out the same dose of coffee.
For most digital scales, batteries are the primary power source. While a pair of AAA batteries make a scale portable and great for travel, there is usually a shelf life.
While batteries are typically commonly found in stores and are not overly expensive, that cost will add up over time. Some manufacturers have innovated more energy-efficient alternatives in using lithium-ion batteries with a type-c rechargeable feature.
Depending on the frequency with which you plan on using your coffee scale, one of these options may be better for you. While the rechargeable battery option may run more expensive than a normal battery-operated coffee scale, users will make up for the added cost by avoiding battery replacements.
With the increase of a coffee scale’s cost, most devices include a variety of features to better oversee the precision of your style. Some of these features include automated timing, taring, and an auto-off function.
Most scales come equipped with a built-in timer that enables users to time your scale to stay up until they’re finished with the coffee-making process. Likewise, this allows users to shut the coffee scale down when time is off. For users who dislike the auto-off feature when brewing coffee, this offers a helpful solution.
Most quality coffee scales incorporate a tare function, whether automated or manual. Since the taring function helps users measure the weight of the container and the ingredient to find a net weight and ensure precision. For users striving for peak consistency, having a coffee scale with a tare option is essential.
While this feature is loved by some and disliked by others, it is helpful in preserving battery life for your scale. For users who forget on occasion to turn off the scale after using it, this is a great feature to have. However, for manual brewers needing a longer brew time, this auto-off feature can shut down your scale before you’re finished making coffee.
Most auto-off features power scales down between 1-5 minutes and some scales even incorporate an adjustable auto-off time for brewers. For those interested in this feature, it’s important to pay attention to the auto-off options.
All in all, when it comes to selecting the best coffee scale option, factors like accuracy, control, and additional features are important considerations. How much or how little control users desire to have over the process is an essential detail in finding the scale best fit for your kitchen.
Whether you plan on using it for weighing ground coffee, a pour-over brew, or an espresso shot, we hope this buying guide narrows your search in picking the perfect scale for you.
