Scales

Scales

A digital scale is one of the simplest tools to improve your roasting. Weighing your green coffee batches brings more consistency to your roasts, while tracking weight loss after roasting helps you understand how far you’ve pushed development. These scales are accurate, fast, and built to handle daily use - ideal for any home setup.

Your guide to Scales

  • Why does weighing green coffee matter in roasting?

    Roasting is all about controlling variables - and batch size is a big one. Even small changes in the amount of green coffee you load can affect how heat moves through the roast. Weighing each batch helps you make adjustments that are consistent and repeatable, instead of guessing and hoping for the best.

  • What can weight loss tell me about my roast?

    Coffee loses moisture as it roasts, and that weight loss tells you a lot about how far the roast has gone. Measuring before and after lets you track development - useful when comparing roasts over time or fine-tuning your process. Many home roasters aim for around 13–16% loss, depending on their target profile.

  • Can I use the same scale for brewing?

    You can - and many people do. As long as the scale is fast, accurate to 0.1g, and has a tare function, it’ll work well for both roasting and brewing. But if roasting is your main focus, make sure the scale is stable, easy to clean, and big enough to handle green coffee batches.

Your questions, answered

Do I really need a scale for home roasting?

If you want more consistent results, yes. Roasting the same weight each time makes it easier to spot what’s working - and what needs adjusting. It’s one of the simplest ways to get more control over your roast.

What kind of scale should I use?

Look for something accurate to 0.1g, with a fast response time and a tare function. It should be sturdy enough for daily use and big enough to handle your typical green coffee batch.

How does batch size affect the roast?

The amount of coffee in the chamber changes how heat moves through the beans. If your batch size varies, you’ll get inconsistent results — even if your roaster settings stay the same. A scale helps remove that guesswork.

Why weigh after roasting?

Tracking weight loss helps you judge roast level more precisely. It’s a reliable reference point when comparing different batches, especially when visual cues aren’t clear or the roasts are days or weeks apart.

Can I use a kitchen scale for roasting?

You can, as long as it’s accurate to 0.1g and responsive. But most standard kitchen scales aren’t designed for quick readings or small batch sizes. A scale built for coffee will usually be faster, more precise, and easier to work with.
