Finish (aftertaste)
Persistence of aromas and flavours after swallowing. Evaluated in SCA cupping on 10 points. A long, clean finish is a quality marker.
What creates a coffee's finish, and why does it linger?
The finish, also called aftertaste or retronasal aftertaste, is the sensory experience that persists in the mouth and nose after the coffee has been swallowed, without any new stimulus. According to the Specialty Coffee Association cupping protocol, it is one of the ten attributes scored on the cupping form and is evaluated for both quality (is it pleasant? complex? clean?) and duration (seconds to minutes of persistence). The mechanism involves two pathways: volatile aromatic compounds released as the coffee warms in the throat rise retronasally (upward into the nasal cavity from the back of the throat), producing olfactory sensations distinct from those perceived on the way in. Non-volatile compounds, including tannins, melanoidins and sugars, interact with residual saliva and taste receptors to produce a lingering chemical taste impression. A great specialty coffee finish is described as 'long', 'clean', 'evolving', and 'complex': starting with one note and transitioning to another over 1 to 3 minutes. A poor finish is 'short', 'astringent', 'bitter', or 'hollow'. High-altitude naturals (Ethiopian Yirgacheffe natural, Panama Geisha natural) consistently produce the longest and most complex finishes in competitive cupping. Over-extracted or burnt coffees leave a harsh, metallic finish that persists uncomfortably.
How do you taste and score a coffee's finish?
To develop finish awareness, practise this: after each sip during a cupping, set a timer for 60 seconds. Note what you perceive at 10 seconds, 30 seconds, and 60 seconds after swallowing. Does the finish evolve or stay static? Does it remain pleasant or become harsh as it cools? At tasting competitions and CoE judging, a clean, complex, and long finish can elevate a coffee from 86 to 89 SCA points. For brewing: a well-extracted cup at the right temperature (93 to 95°C for filter) generally produces the most expressive finish.
