How do I know if my espresso is underextracted?

You can use the `analyze_extraction` tool. If the extraction yield is below 18%, the shot is classified as underextracted, which often tastes sour.

How can I adjust my dose to reach a target yield?

Use the `calculate_dose_adjustment` tool. Provide your current dose, the target yield, the beverage weight, and the TDS to find the required dose change.

What is a realistic TDS for espresso?

Typically, espresso TDS falls between 6% and 12%. You can use `validate_extraction_parameters` to check if your measurements are within reasonable bounds.
