格雷伯爵茶现在已经是一类调味茶的通称,很多茶商都在生产,甚至有Earl Grey Green(格雷伯爵绿茶)。即使如此,川宁也被认为是格雷伯爵茶的最正宗的廠商,也是最好的格雷伯爵茶的生产者。格雷六世伯爵在Twinings所生产的Earl Grey Tea外包裝上自薦說“Twinings has been blending my family tea for many years. Today I am proud that this tradition continues with the tea clelebrated throughout the world known as Twinings's Earl Grey Tea.”
