How to position your mouth and lips for a proper coffee cupping slurp

In professional cupping—used globally in specialty coffee evaluation—the slurp is not about noise or show; it is a sensory technique that maximizes aroma, flavor, and tactile perception. Here is the correct, trainer-level method taught at institutions like Kenya Coffee School and practiced in global protocols.

1. Lip position: relaxed but sealed

Slightly purse your lips as if sipping hot soup
Create a small oval opening, not wide open
Lips should form a tight seal around the spoon edge

👉 Purpose: allows high-speed airflow to pull coffee into the mouth and atomize it.

2. Mouth shape: open and wide inside

Keep your jaw relaxed and slightly open
The tongue stays low and flat
Avoid curling or blocking the tongue

👉 Purpose: creates space for coffee to spread evenly across the palate.

3. The slurp action (critical step)

Take a sharp, fast inhale through the lips
Coffee and air enter simultaneously
Aim to spray the coffee across the tongue and palate

You should hear a distinct slurp sound—this is correct and necessary.

4. Cheeks & airflow control

Keep cheeks neutral, not puffed
Let air move freely toward the back of the mouth
Do not swallow immediately

👉 This airflow pushes volatile aromatics retronasally toward the nose.

5. After the slurp: evaluation phase

Roll the coffee gently with your tongue
Breathe out through the nose (retronasal breathing)
Assess:
- Aroma
- Acidity
- Sweetness
- Body
- Aftertaste
- Balance

Professionals often spit after evaluation to avoid caffeine fatigue.

Common mistakes to avoid

❌ Sipping quietly (limits aroma release)
❌ Lips too wide open (no atomization)
❌ Blocking with tongue
❌ Swallowing immediately
❌ Being shy about the sound
