Which scales are used on the SCA cupping form to measure intensity?

The correct answer is that vertical scales are used on the SCA cupping form to measure intensity. Vertical scales are often employed in sensory evaluation to provide a clear and intuitive way to represent the intensity of various attributes, such as flavor or aroma. In this context, the vertical alignment allows for easy differentiation between varying degrees of intensity, making it straightforward for assessors to mark their perceptions.

Horizontal scales might not provide the same level of clarity when documenting intensity, as they can lead to confusion about the direction of measurement and may not effectively convey the concept of intensity in a sensory context. Therefore, the use of vertical scales is particularly effective in ensuring that evaluators can precisely communicate their sensory experiences in a structured manner. This enhances the reliability and accuracy of the sensory data collected.
