Getting the Right Coffee Beans

Freshness and Roast Level

The freshness of your coffee beans is paramount in achieving the best flavor in pour-over coffee. For optimal results, select beans that have been roasted within two to four weeks. Coffee beans gradually lose their flavor and aroma over time, so it’s important to use them when they are at their peak. Additionally, consider the roast level of the beans. Lighter roasts tend to retain more of the bean’s natural flavors and acidity, while darker roasts impart a bolder, caramelized taste. Experiment with different roast levels to find the one that suits your palate.

Choosing a Single Origin or Blend

When choosing coffee beans for pour-over brewing, you will come across both single origin and blend options. Single origin beans come from one specific region, which allows you to explore the unique flavors and characteristics of that particular area. They often have distinct flavor profiles, ranging from fruity and floral to earthy and nutty. On the other hand, blends combine beans from different regions to create a well-balanced and consistent flavor. Consider your preference for exploration or consistency when deciding between single origin and blend beans.

Grinding Your Beans

Grinding your coffee beans just before brewing is crucial for a flavorful pour-over coffee. The grind size directly influences the extraction process. For pour-over brewing, a medium-fine grind is generally recommended. This consistency allows for a balanced extraction and a clean cup of coffee. Invest in a high-quality burr grinder to ensure a consistent grind size. Avoid using a blade grinder, as it tends to produce uneven particles, leading to an inconsistent extraction.

Water Quality and Temperature
