This is a black tea that I use my rock tea raw material to process. The variety is Chunlan （春兰）which is a high-flavor variety in Wuyishan rock tea. I use this raw material to process oolong tea every year, and then I processed a little into black tea version in 2020 and sent it to WuYi Origin Tea Club numbers . This year I also processed a little as welfare tea, which is affordable and you can drink it every day. But the quality is definitely higher than the regular Tea .
