What To Consider When Purchasing a Digital Coffee Scale?

When it comes to buying a digital coffee scale, there are a few key factors to keep in mind. Gone are the days of bulky, oversized scales with red needles. Here's what you should look for:

Size and Accuracy:

The ideal coffee scale should be small and compact, while still offering accuracy to within two decimal places. It's crucial to ensure that the scale has a tare button, which allows you to reset the mass to zero. This is important because you'll be placing various brewing devices on the scale, and starting from zero before pouring is essential.

Water Resistance:

Consider choosing a water-resistant scale, or at least one that is splash-proof. Even highly skilled baristas can accidentally drip or spill coffee onto the scale. A water-resistant feature will protect your scale from any potential damage.

Is a Built-in Coffee Timer Necessary?

The answer to this question depends on your brewing preferences. A basic coffee scale will suffice for most people who want to weigh their coffee accurately. However, if you anticipate doing a lot of pour-over coffee brewing at home, it's recommended to opt for a scale with a built-in timer. This will make the brewing process more convenient, eliminating the need for a separate timer. Relying on your cell phone for timing can quickly become tiresome.

Why Are Some Scales Better for Pour-Over and Others for Espresso?

Many scales claim to be suitable for both espresso and pour-over brewing techniques. They may boast features like a flow rate meter or a portafilter setting. The issue here lies not in their functionality but in their size and shape. For instance, a scale like the Acaia Pearl S, with a height of 1.5 inches, may not fit well with espresso machines that have limited space under the portafilter. However, there are espresso machines available that can accommodate larger scales, such as Breville machines or the Rancillio Silvia Pro X. When it comes to pour-over brewing, it's important to have a weighing platform large enough to accommodate your chosen vessel. Additionally, a display that is offset or well-removed from the weighing area is beneficial for readability, especially with larger brewers like a Chemex.
