Abstract

The relationship between auction selling price and content of total theaflavins and total colour was investigated for teas sold on 25 occasions between June 1971 and December 1973. The extent to which price depended upon theaflavins and total colour varied according to the geographical area of origin of the tea and to the time of sale. While theaflavin content was generally the best explanation of price, total colour measurement added to the explanation on many occasions, particularly with teas from North East India. Possible ways in which seasonal market supply factors might influence the relationship are discussed.
