Ikawa Green Coffee Beans

Because the Ikawa’s 100g batch size allows for quick, back-to-back roasting, it’s easy to compare different beans and tweak profiles to suit their characteristics. Therefore a wide range of beans work well with an Ikawa. This roaster is ideal for experimenting with new origins, processing methods, or high-quality and rare coffees, where precision is key to unlocking their full flavour potential. By testing and refining different roast approaches, you can develop a deeper understanding of how green coffee characteristics impact flavour and find the right beans for your roasting style.

At Green Coffee Collective, we source some of the best green coffee available—fresh, fully traceable, and packed with flavour. Whether you're looking for a clean, bright washed coffee, a bold and fruit-forward natural, or something more experimental, we’ve got you covered. Our selection is constantly updated with coffees from top producers, each with detailed origin, harvest, and processing information, so you know exactly what you're roasting.

Roasting on an Ikawa is all about precision and experimentation, and we make it easy to find the right beans to match. Our small-batch options mean you can test different origins and processing styles without overcommitting. Whatever you’re looking for, we’ve got coffees that will bring the best out of your Ikawa—and your roasting.

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.

Roasting green coffee beans at home is easier than you think, and it’s a fantastic way to unlock their full flavour potential. You can use tools you already have, like a stovetop popcorn maker, an oven, or a dedicated home roaster.

Start by preheating your device and stirring the beans regularly to ensure an even roast. As they heat, you’ll hear cracks that signal different stages of roasting—from light and fruity to dark and bold. Once you’ve reached your perfect roast, cool the beans quickly to lock in the flavour.

New to roasting with an Ikawa? Or just looking to get more out of your green beans? Here are a few quick tips to help you make the most of each batch:

• Start with the Right Charge Size
  For consistent results, aim for the recommended 50g batch size on the Ikawa Home or 60–100g for the Ikawa Pro. This helps ensure even airflow and predictable roast development.
• Fine-Tune Airflow and Heat
  Ikawa’s strength lies in its precise control of temperature and airflow curves. Small adjustments, especially during first crack or development, can bring out brighter acidity, deeper sweetness, or clearer body.
• Use Roast Profiles as Starting Points
  Every coffee is different. While default or community-shared profiles can be useful, tweaking them to suit your specific green bean will yield the best results. Keep notes, compare cups, and don’t be afraid to experiment.
• Rest, Cup, Repeat
  Let your roasted samples rest at least 24–48 hours before cupping. This gives the coffee time to degas and stabilize, revealing more accurate flavor and aroma notes for evaluation.
