Hsu thinks that the production of Taiwanese-style tea by Taiwanese growers in the mainland has struck a real blow to the market for "pure" Taiwanese tea. "Consumers don't know the difference between 'Taiwanese tea' and 'Taiwanese-style tea," he explains. "So now they think that there's been a serious across-the-board decline in the quality of Taiwanese tea."
茶博士許龍寶則認為，台灣茶農到中國種植的「台式茶」打擊了純種台茶的市場，「消費者搞不清楚『台灣茶』與『台式茶』的差別，還以為台灣茶的整體質量大幅下降了，」他說。
