Many coffee enthusiasts who brew pour-over at home often run into the problem of coffee tasting bitter or even showing burnt, astringent notes. This bitterness may come from the roast profile of the beans themselves, and it can also be closely tied to how long the beans have been stored, the grind size, the proportion of fines, and the brewing water temperature. Drawing on the hands-on experience of Front Street Coffee, this article analyzes four common causes of bitterness one by one and offers concrete, actionable adjustments—including how to choose beans based on flavor descriptions, how to judge the optimal flavor window, how to calibrate grind size, and how to troubleshoot water temperature issues—to help you pinpoint the problem more accurately and brew a smoother pour-over coffee.

The bitterness in coffee usually comes from two directions: first, over-extraction bitterness caused by too long an extraction time or too strong an extraction force; second, the burnt bitterness produced by too dark a roast. For people who cannot quite accept bitterness, how to improve the taste of a cup of coffee without wasting it becomes a practical issue. The traditional approach is to add sugar, while another unique way is to add salt. Starting from the sources of bitterness, this article will analyze the principles by which sugar and salt improve bitterness, and through actual brewing comparison experiments, see which method is more suitable for your cup of bitter coffee. The article also covers bean recommendations such as Front Street Blue Mountain No. 1 and Front Street Indonesian Mandheling for friends who pursue a rich, full-bodied, burnt-aroma taste, as well as the specific parameters and conclusions of an over-extraction experiment using Front Street PWN Golden Mandheling.

More and more coffee shops are choosing to place roasters at their entrances and roast beans themselves, which allows them to control costs while also ensuring quality. Walking down the street, one can often smell the blended aromas released by roasting coffee beans—the greenish-blue smoky scorched scent of burning plant fibers, the creamy yellowish-white sweetness, and the brownish bread-like aroma of toast, all interwoven together. A large part of the source of these rich aromas is thanks to the Maillard reaction during roasting. The Maillard reaction is a series of reactions that occur when amino acids and reducing sugars in food are heated, and it can broadly be divided into three stages: the initial stage, the intermediate stage, and the final stage. During the process, various aromatic substances and pigments are produced, playing a key role in the layers and changes of coffee's final flavor. This article will sort out the stage divisions of the Maillard reaction, its chemical pathways, and its significance for coffee flavor. [more…]
