Spooner's blend, basic flavour whiskey (6,4)

I believe the answer is:

single malt

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

'spooner's blend basic' is the definition.
I can't tell whether this defines the answer.

'flavour whiskey' is the wordplay.
'flavour' becomes 'single' (I can't justify this - if you can you should believe this answer much more).
'whiskey' becomes 'malt whiskey' (malt whiskey is a kind of whiskey).
'single'+'malt'='SINGLE MALT'

Can you help me to learn more?
