The Role of Water Chemistry in Light Roasts
Lightly roasted coffee is exceptionally sensitive to mineral hardness. Hard tap water high in calcium carbonate buffers away bright fruit acids, leaving the cup muddy and flat. Always use filtered water with low bicarbonate (under 40 ppm) to allow high-altitude aromas to shine.
