Dandy Joseph with Lisa blending wine (10)
I believe the answer is:
beaujolais
'wine' is the definition.
(Beaujolais is an example)
'dandy joseph with lisa blending' is the wordplay.
'dandy' becomes 'beau' (synonyms).
'joseph with' becomes 'jo' (I can't justify this - if you can you should believe this answer much more).
'blending' indicates anagramming the letters (letters blended or mixed into a new form).
'lisa' is an anagram of 'lais'.
'beau'+'jo'+'lais'='BEAUJOLAIS'
Can you help me to learn more?
(Other definitions for beaujolais that I've seen before include "drink" , "Light red wine from south-east France" , "French light red wine" , "Burgundy wine" .)
