Key ideas in How to Taste Coffee
- Slurping sprays the coffee into a fine mist (aeration)
- Smell is the primary driver of what we call 'flavor' in coffee
- Aeration ensures the coffee hits all taste receptors on the tongue simultaneously
- The tongue only detects basic tastes like bitter, sour, and sweet
- The purpose of slurping during a coffee tasting
- Complex aromatic notes are perceived through the nose (retronasal olfaction)
- A gentle sip limits the coffee to the front of the mouth, missing complex notes
- The role of smell in flavor perception
- High heat masks acidity and subtle sweetness
- Strength refers to the concentration of coffee solids
- As coffee reaches body temperature, fruit notes become apparent
- Bitterness is a specific sharp flavor
- How coffee flavor evolves as it cools
- A coffee can be strong without being bitter
- The bubbles (carbonation) help scrub the tongue of oils from the previous coffee
- Repeatedly tasting coffee without a break leads to 'flavor fatigue' where everything tastes the same
