Wine from loch in new crate (6)
I believe the answer is:
claret
'wine' is the definition.
(claret is a kind of wine)
'loch in new crate' is the wordplay.
'loch' becomes 'l'.
'in' indicates putting letters inside.
'new' is an anagram indicator.
'crate' with letters rearranged gives 'caret'.
'l' inserted into 'caret' is 'CLARET'.
'from' is the link.
(Other definitions for claret that I've seen before include "Deep purplish colour" , "Type of red wine" , "Dark purplish-red colour" , "English word for red Bordeaux wine" , "French wine" .)
