Black tea

TeaHQ has written about this pair

Chai is a preparation, not a tea. Understanding that resolves most of the confusion about why the leaf sold for it tastes harsh on its own.

What it is
Assam: Orthodox or CTC Assam sold to be drunk as tea.Chai blend base: Small-particle CTC Assam, manufactured to extract fast and hard.
How it is prepared
Assam: Steeped in hot water for a few minutes.Chai blend base: Simmered with water, milk, sugar and spice, brought to the boil more than once.
Why the leaf is cut so small
Assam: Leaf size is chosen for the character wanted in the cup.Chai blend base: It must stay visible through milk, sugar and spice, which whole leaf does not do.
Drunk plain
Assam: Fine, with or without milk.Chai blend base: Harsh and tannic, and not intended to be.
Is it a lesser tea
Assam: No.Chai blend base: No. It is engineered for a job that whole leaf does badly.

In summary: Judge the chai base by the chai, not by a plain cup. It is one of the clearest cases in tea of a product being designed for a preparation rather than for itself.

Nothing above is a recommendation. The last row describes the drinker each tea suits, using each tea’s own authored fields and the same sentence structure for both, so neither can be framed as the safe choice.
