<p>Provided is a high-concentration tea polyphenol extract which has a non-polymeric catechin composition close to tea from a pot and shows reduced bitterness/astringency and no sourness. Also provided is a method whereby the aforesaid extract can be produced at a low cost. A tea polyphenol composition characterized by: (A) the content of non-polymeric catechins being 60 mass% or more relative to the tea polyphenol composition; and (B) the content of gallocatechin in the non-polymeric catechins being 8-20 mass% relative to the total non-polymeric catechins. In the tea polyphenol composition, it is preferred that the ratio represented by gallate-form non-polymeric catechins (epigallocatechin gallate + epicatechin gallate + gallocatechin gallate + catechin gallate)/free-form non-polymeric catechins (epicatechin + epigallocatechin + gallocatechin + catechin) is 0.1-1.</p>
