To provide a manufacturing method of tea leaves having good balance of roasted flavor and flavor originally obtained by tea, integrated feeling of flavor and taste and high palatability while suppressing burning smell by roasting sufficiently, and a manufacturing method therefor.SOLUTION: There is provided a manufacturing method of roasted tea leaves having following processes 1 to 3. [Process 1] a process for adding alkali liquid to tea leaves before roasting. [Process 2] a process for storing tea leaves obtained in the Process 1 at a constant temperature. [Process 3] a process for roasting tea leaves obtained in the Process 2. There is provided a manufacturing method of roasted tea leaves, in which 20 to 40 wt.% of an alkali solution containing 2 wt.% to 30 wt.% of at least one or more kind selected from sodium hydrogen carbonate, sodium carbonate, potassium carbonate, sodium hydroxide and potassium hydroxide to the tea leaves so that pH of an extract by water of weight of 50 times to the tea leaves before roasting is in a range of over 5.5 and less than 8.5 in the Process 1, and the constant temperature of tea leaves during roasting is more than 140°C to 180°C in the Process 3.SELECTED DRAWING: None【課題】焙煎によるこげ臭を十分に抑制しながらも、焙煎香と茶本来の香味とのバランスがよく、香りと味の一体感を有する嗜好性の高い茶葉およびその製造方法の提供。【解決手段】次の工程1~3を有する焙煎茶葉の製造方法。〈工程1〉焙煎前の茶葉にアルカリ液を添加する工程。〈工程2〉工程1で得られた茶葉を定温で保管する工程。〈工程3〉工程2で得られた茶葉を焙煎する工程。工程1において、焙煎前の茶葉に対して50倍量の重量の水による抽出液のpHが5.5を超え、且つ8.5未満の範囲となるよう、炭酸水素ナトリウム、炭酸ナトリウム、炭酸カリウム、水酸化ナトリウム、及び水酸化カリウムから選ばれる少なくとも一種または二種以上を2重量%~30重量%含有するアルカリ性水溶液を、茶葉に対して20~40重量%を添加し、工程3において、焙煎時の茶葉の品温を、140℃を超える温度から180℃以下とする、前記焙煎茶葉の製造方法。【選択図】なし
