Mellow wine, like certain spirits (7)
I believe the answer is:
kindred
'like certain spirits' is the definition.
'kindred' can be an answer for 'like' (I've seen this before). I'm not sure about the 'certain spirits' bit.
'mellow wine' is the wordplay.
'mellow' becomes 'kind' (I can't justify this - if you can you should give a lot more credence to this answer).
'wine' becomes 'red wine' (red is a type of wine).
'kind'+'red'='KINDRED'
Can you help me to learn more?
(Other definitions for kindred that I've seen before include "clan" , "Affinity" , "Congenial" , "Family - similar" , "Family and relations" .)
