Some fermented crops are used as an ingredient in this quasi-lager (6)

I believe the answer is:

silage

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

'some fermented crops are used as an ingredient in this quasi-lager' is the definition.
The definition suggests a singular noun which matches the answer.

'in this quasi-lager' is the wordplay.
'in' indicates a hidden word.
'SILAGE' is hidden in the letters of 'this quasi lager'.

Can you help me to learn more?

(Other definitions for silage that I've seen before include "Fodder in store" , "Preserved fodder for cattle" , "Stored, dried animal fodder" , "Form of fodder" , "Animal food" .)

I've seen this clue in The Irish Times.
