If a person who loves food is a foodie, what do you call someone who loves tea?

Someone who drink a lot of tea is called a ‘theic’.
You pronounce it as ‘thee’ as in theme -ic. So ‘thee-ic’!

teahard, har har (like, diehard for tea)

I think you’d call them me

Perhaps we should just be called wise or clever…. for knowing the difference between good tea or generic tea bags

A teaeerie.
