Dark Roast Coffee Extraction Method

Dark roast coffee refers to French or Italian roast coffee that has undergone the second crack during the roasting stage. This type of coffee is designed to enjoy intense bitterness, the sweetness that emerges from the bitterness, and a long-lasting aftertaste. Therefore, it is more suitable for strong extraction, as light extraction makes it difficult to appreciate its rich texture.

When extracting dark roast coffee, if the concentration is insufficient, the overall texture will decline. Moreover, compared to other flavors, the bitterness becomes irritating and prominent, with a burnt taste. Therefore, if you want to enjoy the long-lasting aftertaste of dark roast coffee, you might as well choose rich extraction.

The bitterness of coffee cannot be removed or reduced, but the type of bitterness is also very important. Some bitterness is refreshing like mint or peppermint, making people feel pleasant, while other bitterness is like antibiotics or traditional Chinese medicine, making people feel miserable. Only through careful adjustment can we extract pleasant, high-quality bitterness.

To extract richer aroma, typically more coffee is used. Increasing the amount of coffee can obtain more coffee components, thereby creating richer coffee. Generally, for extracting one cup (120mL), 20g of coffee is used. To extract more coffee components, you can also extend the extraction time (2.5-5 minutes). This makes the contact time between coffee and water longer, allowing more coffee components to dissolve. Additionally, dark roast coffee has a rich aroma. To enhance texture while suppressing bitterness, it is usually extracted at low temperatures for a long time (80-82°C, 2.5-5 minutes).
