Reminder to store strong drink (8)
I believe the answer is:
keepsake
'reminder' is the definition.
(thesaurus)
'store strong drink' is the wordplay.
'store' becomes 'keep'.
'strong drink' becomes 'sake'.
'keep'+'sake'='KEEPSAKE'
'to' is the link.
(Other definitions for keepsake that I've seen before include "one recalls" , "Something of sentimental value" , "token" , "to remember one by" , "It serves to keep a person in mind" .)
