MediumRoastSteam Sensory scores are usually out of an odd number, starting at ‘1’ to allow a neutral ‘neither like, nor dislike’. I use the 9 point quartermasters hedonic scale that is very common in sensory research for the liking of food & drink:
1 = Dislike extremely; 2 = Dislike a lot; 3 = Dislike moderately; 4 = Dislike a little; 5 = Neither like nor dislike; 6 = Like a little; 7 = Like moderately; 8 = Like a lot; 9 = Like extremely.
6.75 is the average over a few brews, I tend to stick to whole integers for individual brews.
