Initial Brew Temp (°C) 88.0°C

Ambient Room Temp (°C) 21.0°C

Beverage Volume (ml) 250 ml

Vessel Material Ceramic

Sensory Note: At temperatures above 65°C, volatile aromatic perception is muted by thermal numbness and burn inhibition. True flavor complexity (acidity, floral notes, sweet origin character) fully unfurls between 55°C and 60°C.

Sources & Empirical Basis:

• The Economist: "Hot coffee could cause oesophageal cancer" & sensory cup temperature profiles.

• International Agency for Research on Cancer (IARC / WHO): Classification of very hot beverages (>65°C) as Group 2A probable carcinogens due to recurrent thermal epithelial trauma.

• Specialty Coffee Association (SCA) cupping protocol guidelines for sensory evaluation window (55°C – 60°C).
