[BREWMENT] Why does my coffee taste bitter even though I used expensive beans?

Expensive beans don't guarantee a great cup if the Surface Area of your grind is mismatched with your brewing method. This is a matter of Solubility Dynamics. Coffee is 98% water, and the flavor comes from the 1.2% to 1.5% of dissolved solids. If your grind is too fine, the water extracts the "heavy" bitter compounds (Over-extraction). If it's too coarse, it only grabs the "bright" acids (Under-extraction).

At BREWMENT, we advocate for the Uniformity of Particle Size. A high-quality burr grinder ensures that every coffee "chunk" is the same size, allowing the water to pass through the "puck" at a consistent rate, resulting in a balanced, sweet, and complex cup.

The "Grind-to-Method" Blueprint:

1. Coarse (Sea Salt size): Best for French Press. Long immersion time needs larger particles to prevent bitterness.

2. Medium (Table Salt size): Ideal for Drip or Pour-over. The standard for most home brewers.

3. Fine (Powder size): Essential for Espresso. High pressure requires a dense "resistance" to create the perfect crema.

Use Case: This is a vital lesson for the home barista who just invested in a premium specialty coffee bag. By adjusting your grind size instead of just adding more coffee, you can unlock the "hidden" notes of blueberry or chocolate that the roaster intended.
