Darjeeling tea is a special blend of tea orignating from India.
In an unknown, alternate future timeframe, Jean-Luc Picard was not pleased with the tea served by Data's maid Jessel, asking her if she hadn't served Darjeeling instead of Earl Grey, a question she chose to ignore. (TNG: "All Good Things...")
- In an early draft of the script for "Contagion", Picard ordered Darjeeling tea, however, this reference was changed, and became the first time he ever uttered: "tea, Earl Grey, hot."
