Longjing 龙井 - 4 and more stars - 5 stars

„gaiwan; 盖碗 - literally lid-bowl. A steeping bowl with a lid. They generally come in two or three sizes. The most common is 140cl/4oz. The lid is used to clear off any extraneous materials that may float to the surface on flushing and initial steepings. These (1 or 2) are typically not drunk. The lid is then used to partially strain the tea by holding it a little to one side as one pours the tea off through a fine strainer into a gong dao bei (共道杯) or decanting jug.“
