Just-About-Right scale explained

The Just-About-Right scale (JAR scale), is a sensory evaluation tool used to measure the intensity of a particular attribute or characteristic of a product or service. The JAR scale typically consists of 5 levels ranging from "Much too little" to "Much too much."^{[1] [2]}

The JAR scale focuses on specific attributes of a product such as sweetness, saltiness, texture, etc., or service such as expediency, cost, etc.

The JAR scale is criticized for measuring attribute intensity and acceptability simultaneously.^[3]
