Numbers of correct judgments for off-flavor substances in triangle tests

Substance/solvent	Concentration/judgments
TCA	3 ppt (14 pM)	10 ppt (47 pM)	15 ppt (71 pM)
Red wine	7	12*	—
White wine	5	3	15*
TBA	10 ppt (29 pM)	30 ppt (87 pM)	100 ppt (290 pM)
Red wine	4	7	13*
White wine	6	5	12*
TCP	30 ppb (152 nM)	100 ppb (506 nM)	300 ppb (1,518 nM)
Red wine	6	6	11*
White wine	4	12*	—

^*According to binominal tables, 11 or more correct judgments are significantly above chance at P < 0.05 (n = 20).
