'alcoholic drink' is the definition.
'sangria' can be an answer for 'drink' (type of alcoholic drink). I'm not sure about the 'alcoholic' bit.

'grain as processed' is the wordplay.
'processed' indicates anagramming the letters.
'grain'+'as'='grainas'
'grainas' anagrammed gives 'SANGRIA'.

'for' is the link.

Can you help me to learn more?

(Other definitions for sangria that I've seen before include "Spanish sweetened wine drink" , "Mixed drink" , "Spicy Spanish wine drink" , "Spanish wine punch" , "Spanish alcoholic drink" .)
