Your guide to Roest Green Coffee Beans for Roasting

  • How do I choose the right green beans for my Roest roaster?

    Roest roasters give you full control over temperature, airflow, and time, making them ideal for exploring different coffee styles. The type of bean you choose will shape the flavour, so it’s worth experimenting. Washed coffees tend to roast cleanly, bringing out acidity and clarity, while natural and honey-processed beans have more sugars, affecting caramelisation and body. Experimental processes—like anaerobic or thermal shock—can behave unpredictably but unlock bold, complex flavours. Because Roest allows for fine adjustments and data tracking, it’s an excellent tool for comparing different origins and processing methods, helping you refine your roasting approach over time.

    At Green Coffee Collective, we offer a wide range of high-quality green coffees, perfect for Roest users looking to push their roasting further. Whether you're after a bright washed Ethiopian, a rich natural from Brazil, or something more unusual, we’ve got coffees that will bring the best out of your Roest roaster.

  • Where can I buy high-quality green coffee beans for my Roest roaster?

    At Green Coffee Collective, we source exceptional green coffee, perfect for Roest users who want precision and consistency in their roasting. Our selection includes a wide range of washed, natural, and experimental coffees, all chosen for their freshness, traceability, and unique flavour potential.

    Roest’s control over temperature and airflow makes it easy to experiment, but the right beans make all the difference. If you're refining your roast profiles, testing different processing methods, or exploring new origins, our coffees are chosen to help you get the best from your Roest. Our stock is regularly updated, so there’s always something new to try.

  • How do I store my green coffee beans for the best roasting results?

    Proper storage is key to maintaining the freshness and flavour of your green coffee beans. Keep them in a cool, stable environment—ideally between 20-25°C (68-77°F) with humidity around 60%. Too much moisture can cause spoilage, while overly dry conditions can lead to a loss of flavour.

    Light exposure can also degrade your beans over time. Store them in opaque, airtight containers or a dark cupboard to protect them from UV damage. Minimising air contact is just as important—oxygen speeds up oxidation, which dulls the coffee’s character. Vacuum-sealed bags or airtight storage solutions help slow this process, keeping your beans in peak condition for roasting.

  • How to roast green coffee beans at home?

    Roasting green coffee beans at home is simple once you get the hang of it. Use a stovetop popcorn maker, an oven, or a home coffee roaster. Preheat your chosen device, and stir the beans continuously for an even roast.

    As the beans roast, you’ll hear cracks. These signal different roast stages, from light to dark. A light roast will bring out fruity, acidic notes, while a darker roast will give you bolder, richer flavours.

    Once you’ve hit your preferred roast, cool the beans quickly to lock in the flavour. Experiment with different roast profiles to find what works for you. Need more help? Check out our blog: How to Start Roasting Coffee at Home: All Your Questions Answered!
