Sensory discrimination of single hop beers by using sorting combined with profiling and intensity rating

Abstract

Sensory methodologies are continuously being optimized based on industry needs. Sorting is a widely used sensory method; however, it provides limited information about the uniqueness of individual products. The present work was performed on nine single-hop beers using a combination of sorting with profiling and intensity rating (SPIR) rating to highlight the intra-group variability and individual characteristics. Results have shown that SPIR can effectively highlight the intra-group differences. It has also shown that a higher frequency of citation did not always correspond to a higher attribute intensity. For the considered application, the results highlighted the role of hop varieties on the sensory profile of beers. Overall sensory similarities were found between Mosaic (MO), Citra (CI), and Celeia (CE) hops. However, the use of SPIR highlighted differences between CE and the other hops. Amarillo (AM) hops showed the most distinctive profile in all cases.

Practical applications

The use of sorting in combination with profiling and intensity rating (SPIR) rating can be a valuable tool in new product development. It is not only important to understand the overall sensory similarities and differences between groups of samples, but also unique aspects compared to similar products. The present work has shown that adding intensity to sorting and profiling can highlight the inner characteristics of individual products in a group of samples with an overall similar sensory profile.
