    Description

    You can roast the same coffee a dozen times and get a dozen different results. Even small changes in roast degree have an outsized impact on the final flavour in the cup - but relying on sight and smell alone to judge colour consistency is an uphill battle.

    The CoffMeter A1 puts objective measurement within reach. It's a compact, easy-to-use roast color analyzer that gives you Agtron readings to ±0.5 accuracy in seconds, no lab equipment required. Designed for the serious home roaster, it brings a new level of precision and repeatability to the craft without the complexity or cost of commercial-grade tools.

    Hitting Your Target Roast Level Is Only Half the Battle

    Consistency is the real challenge - reproducing that perfect roast time after time. Even with careful logging and identical settings, batch-to-batch variations in colour can be significant, and they have a big impact on flavour in the cup. The CoffMeter A1's precise Agtron measurements take the guesswork out of colour evaluation, so you can focus on the variables that actually move the needle. With objective data points for every roast, you can spot inconsistencies, make informed adjustments, and get closer to your target profile with every batch.

    Speak the Same Language as the Pros

    Agtron colour scores are the industry standard for a reason - they enable clear communication and target-setting across teams and supply chains. When you're cupping coffees from different roasters or discussing roast profiles with other professionals, having a common language matters. With the A1 in your toolkit, you can use the same objective scale as other roasters to better understand and replicate their results. Plus, being able to talk about roast degree in terms of Agtron numbers shows that you're serious about your craft and can communicate effectively with other coffee pros.

    Profiling a New Coffee? Start with Hard Data

    Developing a roast profile for a new origin or lot involves a lot of trial and error. But without objective colour data, it's hard to know whether you're moving in the right direction with each iteration. The CoffMeter A1 gives you a clear benchmark to work from. Accurate Agtron measurements help you establish guardrails and make informed decisions as you dial in - so you waste less coffee and reach your target faster. By tracking colour data alongside your other roast metrics, you can build a clearer picture of how different variables affect the final product and create reproducible profiles with confidence.

    Understand the Impact of Roast on Extraction

    Roast degree has a significant impact on a coffee's solubility and ideal brew parameters. A light roast might taste under-extracted at a grind size that works perfectly for a darker roast of the same bean. But without precise colour data, it can be hard to know how to adapt your brewing to get the best from each batch. With the CoffMeter A1, you can measure the exact Agtron value of every roast and use that information to fine-tune your grind size, brew ratio, and technique. By understanding how colour affects extraction in your brewing setup, you can unlock the full potential of each coffee and achieve more consistent results in the cup.

    Frequent Questions

    How do I calibrate the A1?

    Calibrating the A1 is quick and easy. It comes with a set of three colour calibration plates (light, medium, dark). To calibrate, simply select "Calibration" in the menu, follow the prompts to scan each plate, and the device will adjust itself automatically. We recommend calibrating every 30 uses or if the device has been physically shocked.

    What's the difference between the A1 and more expensive roast colour meters?

    The A1 is designed specifically for home roasters and small batch roasting. It offers accurate Agtron colour measurement (±0.5) in a compact, affordable package. Higher-end meters like our DiFluid Omni offer additional features like real-time graphing and integration with professional roast logging software, but the A1 provides the essentials for precise colour tracking in a home roasting setting.

    Can I use the A1 with ground coffee, or only whole beans?

    The A1 works with both whole bean and ground coffee. For best results with ground coffee, we recommend using a medium-fine grind and tapping the sample dish a few times to settle the grounds evenly before measuring.

    How many measurements can I take on a single charge?

    The A1's rechargeable battery provides up to 10 hours of continuous use, or roughly 300-400 measurements, on a single charge. It fully recharges in about 4 hours via the included USB-C cable.

    Does the A1 work with the CoffeeOS app?

    Yes, the A1 connects to the free CoffeeOS app via Bluetooth. The app lets you track and log your color measurements over time, monitor battery level, and install firmware updates. However, the app isn't required to use the A1 - all the core measurement functions are available on the device itself.

    What's the warranty and support like?

    The CoffMeter A1 comes with a 1-year manufacturer's warranty against defects, and our customer support team is available to help troubleshoot any issues you may encounter. We also offer an extensive online knowledge base with tutorials, FAQs, and guides to help you get the most out of your device.
