WBC Sensory Judge Competencies & Rules
World Barista Championship rules are versioned annual authority. This page uses the current 2026 WBC Official Rules and the official 2026 Summary of Rule Changes. Prior-year material remains historical.
Use the Current 2026 Competition Authority
The current rule set governs the 2026 World Barista Championship. Current website claims must stay tied to that competition year.
Current Espresso Definition
The current authority describes espresso as around 1 fl. oz. / 30 ml. The older strict 30 mL ±5 mL wording belongs to prior rule context.
Machine Parameters Are Rule-Year Specific
The 2026 authority records brewing temperature of 90.5–96.0°C and pump pressure of 8.5–9.5 bar. These are competition parameters rather than universal espresso rules.
| 2026 WBC Parameter | Current Value | Unit |
|---|---|---|
| Espresso Reference Volume | Around 30 | mL |
| Brewing Temperature | 90.5 to 96.0 | °C |
| Pump Pressure | 8.5 to 9.5 | bar |
