Winding path to reed grass (4,6)

I believe the answer is:

deep throat

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

'grass' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'winding path to reed' is the wordplay.
'winding' indicates anagramming the letters.
'path'+'to'+'reed'='pathtoreed'
'pathtoreed' with letters rearranged gives 'DEEP THROAT'.

Can you help me to learn more?

(Other definitions for deep throat that I've seen before include "Secret informer" , "Key informant" , "9d [WHISTLE BLOWER]" .)

I've seen this clue in The Times.
