西湖龙井 (Xīhú Lóngjǐng) — flat, jade-green, pan-fired in a wok by hand — is the prestige Chinese green tea. The name comes from a well
龙井 ('Dragon Well') in the hills west of Hangzhou's West Lake. Pre-Qingming (
明前) leaves picked before April 5 are the priciest grade; the Qing emperor Qianlong famously personally favored eighteen tea bushes in front of Hugong Temple, still designated
御茶 'imperial tea.'
