That’s a loss of 3.5°C before a single drop has passed through the coffee . Add evaporative cooling (the enthalpy of vaporization of water is ~2260 J/g) and radiative losses from the brewer’s walls, and your extraction temperature may fall below 88°C—the threshold where sour, under-extracted flavors dominate.
No grinder is perfect. Every "setting" produces a mix of large chunks (boulders) and microscopic dust (fines). Fines have an incredibly high surface area and can easily lead to over-extraction and bitterness if not managed. 2. Mass Transfer: How Flavor Moves
If you're interested in reading the full paper, I can try to provide you with a link or a summary of the key points. Alternatively, you can search for "The Physics of Filter Coffee" by James Hoffmann online.
When you pour hot water over the coffee grounds in a filter coffee maker, several physical processes occur:
