Carbonate system and buffering

Key Concepts

• Carbonate System Components:

• Bicarbonate (HCO₃⁻), carbonate (CO₃²⁻), and dissolved CO₂ are the main species.

• They interact to resist changes in pH when acids or bases are introduced.

• Buffering Capacity:

• Water with high bicarbonate levels can neutralize coffee acids during extraction.

• Strong buffering can lead to muted acidity and a flatter flavor profile.

• Practical Implications for Coffee:

• Understanding the carbonate system helps in adjusting brewing water to highlight desired flavors.

• Blending soft water with mineral additives can fine-tune taste.

• Monitoring & Adjustment:

• Titration or test kits measure total alkalinity, reflecting the buffering strength.

• Adjusting water chemistry ensures consistent extraction and balanced flavor.
