FAQ
1. What is the ideal TDS level for espresso water?
The optimal TDS (Total Dissolved Solids) level for espresso water ranges from 75-150 ppm, with most professionals targeting around 100-120 ppm. This range provides sufficient minerals for proper extraction while avoiding over-mineralization that can create harsh or bitter flavors. Higher TDS levels may lead to over-extraction, while lower levels can result in under-extraction and weak, sour shots.
2. How often should I test my water quality for espresso preparation?
Water quality should be tested at least weekly for commercial operations and monthly for home use. However, if you notice changes in extraction time, flavor profile, or crema formation, immediate testing is recommended. Municipal water supplies can experience seasonal variations, and filtration systems require monitoring to ensure consistent performance over time.
3. Can I use distilled water as a base for my calculated espresso water recipe?
Yes, distilled water provides an excellent base for calculated water recipes because it offers complete control over mineral content. Starting with distilled water eliminates variables from source water and allows precise addition of specific minerals according to your calculator's recommendations. This approach is particularly valuable for achieving consistent results across different locations or when source water quality varies significantly.
4. What minerals are most important for espresso extraction?
Calcium and magnesium are the most critical minerals for espresso extraction. Calcium enhances sweetness and body while contributing to crema formation, with optimal levels between 17-85 ppm. Magnesium improves extraction efficiency and highlights acidity, with target levels of 5-30 ppm. Alkalinity, primarily from bicarbonate, buffers acidity and should be maintained between 40-70 ppm for balanced flavor development.
5. How do I know if my calculated water recipe is working correctly?
Monitor extraction time, flavor balance, and crema formation to evaluate your water recipe's effectiveness. Properly calculated water should produce consistent extraction times within your target range, balanced flavor without excessive sourness or bitterness, and rich, stable crema. Additionally, track equipment performance and descaling frequency, as optimal water chemistry should minimize scale formation while maintaining equipment longevity.
