Overview¶

Aftertaste (also called finish) refers to the flavours and sensations that persist in the mouth and throat after swallowing coffee. In the SCA cupping protocol, aftertaste is a scored attribute alongside flavour, acidity, body, and balance. The length and quality of the aftertaste are considered indicators of coffee quality — a long, clean, sweet finish is characteristic of high-scoring specialty coffees, while short or unpleasant aftertastes indicate extraction or roast defects.

Positive Aftertaste Traits¶

Sweet: Lingering sweetness after swallowing; associated with well-developed roast and good extraction
Clean: No off-notes or contaminating flavours in the finish
Lingering: Flavour and sensation persist for several seconds to minutes; indicates high-quality coffee with complex aromatic compounds
Balanced: Finish reflects the overall cup character without amplifying any single undesirable note

Negative Aftertaste Traits¶

Ashy: Residual ash or tobacco-like sensation; typically from over-roasting or dark roast profiles
Bitter: Persistent bitterness; associated with over-extraction or overly dark roast development
Astringent: Drying, puckering sensation; associated with over-extraction, under-ripened cherry, or robusta content
Dry: Absence of moisture in the mouth after swallowing; associated with astringency or poor extraction
Fermented/Sour: Unpleasant lingering sourness; associated with under-extraction, light roasting, or fermentation defects

Factors Influencing Aftertaste¶

Roast Development¶

Dark roasting drives pyrazine and carbon-based compounds that produce the characteristic ashy, bitter finish common in darker roasts. Lighter roasts preserve floral and fruit-based compounds that produce sweeter, more complex finishes but can leave sour notes if under-extracted.

Extraction Quality¶

Over-extraction produces bitter, astringent, or hollow finishes. Under-extraction produces sour or salty finishes that lack sweetness. Correctly extracted coffee produces a finish that mirrors and extends the cup's main flavour character.

Brewing Method¶

Immersion methods (French press, AeroPress) tend to produce heavier, longer finishes due to increased body. Filter methods produce cleaner, shorter finishes. Espresso produces the most concentrated and persistent finish due to its high extraction concentration.

SCA Cupping Protocol¶

In SCA cupping, aftertaste is scored from 6 (good) to 10 (outstanding) with 0.25-point increments. Evaluators assess: - Quality: Whether the finish is pleasant and desirable - Length: How long the aftertaste persists after swallowing

A high-quality aftertaste score requires both positive character and sufficient length.

Key Facts¶

Aftertaste is the flavour and sensation remaining after swallowing, also referred to as finish
It is a scored attribute in the SCA cupping protocol, evaluated for both quality and length
Long, sweet, clean finishes indicate high-quality specialty coffee
Bitterness and astringency in the aftertaste are the most common negative defects and are associated with over-extraction or over-roasting
Brewing method significantly influences aftertaste length and character
