An extract or the like that can add not just bitterness and fragrance, but taste such as richness or robustness, without enhancing astringency or acridity, as well as a beverage having excellent richness or robustness, is provided. Polyphenols derived from hop, especially those containing reduced proanthocyanidin monomers and a relatively high amount of proanthocyanidin dimers to proanthocyanidin tetramers, can add richness or robustness to a beverage without enhancing an astringent taste or lack of snappiness.本發明之課題係提供一種不會使澀味與辣味增強，不僅具有苦味與香氣，且可賦予醇厚口感與美味等風味之萃取物等，以及提供具有優異的醇厚口感與美味之飲料。本發明之技術方式係即使為來自啤酒花的多酚中，藉由特別使單體原花青素含量降低，相對地使雙體~四聚體原花青素含量增加，而不使飲料的收斂味與飲後喉韻不佳增強，且可賦予飲料醇厚口感與美味。
