Tea is an A if you make it yourself and don't add any sugar (except maybe a slice of lemon). I do cold brew a lot in the warmer months, really hits the spot and doesn't taste like drinking corn syrup.
Iโd say tea is an S tier because itโs so versatile. You can have a mild herbal tea thatโs barely different to water over intense, naturally sweet fruit teas to ice tea so sweet it puts Lipton to shame. The choice is yours. Water is just water. Still very good, definitely A but itโs still just waterโฆ
