Drink of which matcha and sencha are types (5,3)

Ross

I believe the answer is:

green tea

I'm a little stuck... Click here to teach me more about this clue!

'drink' is the definition.
(type of tea)

'which matcha and sencha are types' is the wordplay.
I cannot quite understand how this works, but
'and' could be 'n' (common abbreviation for 'and') and 'n' is found in the answer.
'are' could be 'a' (short for 'are', historical unit of measurement) and 'a' is found within the answer.
The remaining letters 'greete' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

'of' is the link.

Can you help me to learn more?
