Must beers be evaluated in the sequence specified on the flight sheet?

When evaluating beers during a judging session, it is generally understood that judges have the flexibility to assess the beers in any order they choose. This flexibility allows judges to sample and evaluate beers based on their own preference and palate sensitivity at any point during the tasting.

Evaluating beers in a particular sequence can lead to biases or a negative impact on a judge's ability to discern flavors, aromas, and characteristics due to palate fatigue or overwhelming sensations from previously tasted beers. As such, this approach emphasizes a more personal and informative assessment process, allowing judges to make robust comparisons and appraisals based on their immediate sensory experiences.

The other options suggest various constraints that do not align with the standard practices of beer judging, which is built around the idea that individual judges best understand their own tasting process.
