Why Does Coffee Taste Bitter?

The bitterness in coffee is mainly due to the presence of certain chemical compounds released during the extraction process, particularly when coffee is either under-extracted or over-extracted.

When coffee is under-extracted, not enough compounds are drawn out, resulting in a lack of sweetness and nuanced flavors, leading to a sour taste. On the other hand, over-extraction can bring out excessive bitter compounds, overwhelming the palate with an unpleasant, astringent taste. Finding the perfect balance in extraction is crucial for achieving a well-rounded and enjoyable coffee experience.
