* Earl Grey: This is the most common variety of tea associated with Picard. He frequently drinks it in the series, and it's often mentioned in dialogue.
* "Hot, Strong, and Sweet": Picard's preference for a strong, sweet tea is mentioned in the episode "The Best of Both Worlds, Part II."
* English Breakfast: Given his British heritage, it's possible that Picard also enjoys English Breakfast tea.
Therefore, while it's not definitively stated, it's safe to assume that Earl Grey is likely Picard's favourite tea, especially since it fits his preference for strong, sweet tea. However, he may also enjoy other varieties, like English Breakfast, especially when indulging in a classic English tradition.
