Drink from California and Virginia (4)
I believe the answer is:
cava
'drink' is the definition.
(alcoholic drink)
'california and virginia' is the wordplay.
'california' becomes 'ca'.
'and' means one lot of letters go next to another.
'virginia' becomes 'va' (US state abbreviation).
'ca'+'va'='CAVA'
'from' acts as a link.
(Other definitions for cava that I've seen before include "Spanish bubbly" , "Sparkler" , "Spanish "champagne"" , "Spanish sparking wine" , "Spanish sparkling white wine" .)
