- Final Pour: Slowly pour the remaining water in a controlled manner, starting from the center and moving outward.
- Completion: Allow the coffee to drip fully into the carafe or cup.
Fine-Tuning Your Grind for Unique Profiles
As you become more experienced, you may want to experiment further with grind size and coffee flavors. Each coffee bean comes from various origins and has unique flavor notes. Here are some tips on how to fine-tune your grind size for specific flavors:
Light Roast vs. Dark Roast
- Light Roasts: These tend to be denser and can benefit from a slightly coarser grind to allow proper extraction, ensuring sweet and fruity notes shine through.
- Dark Roasts: A finer grind may be used, as the natural oils in the beans are more prominent, lending a fuller body and a bolder flavor.
Single-Origin vs. Blends
- Single-Origin Beans: These often have specific tasting notes that can be highlighted with precision in grind size. Experimentation will allow you to find the sweet spot for your chosen origin.
- Blends: When using blends, it’s ideal to use a medium grind, as it balances the diverse flavor notes present in the mix.
