SUMMARY: Four samples of instant coffee, which varied only in str̀ength, were preference tested by 1152 coffee drinkers by three different methods. Half tested by paired comparisons with two pairs served, one-third used 3-sample rank order and one-sixth used 4-sample rank order. The direction of preference was the same with all methods. The weaker coffees were preferred over the stronger ones. Within the paired comparison method, discrimination was slightly better with the second than with the first pair. Paired comparisons and 3-sample rank order discriminated equally well. Discrimination by 4-sample rank order was slightly poorer than with the other two methods when the between-sample differences were small.
