It's one variety of vines or bubbly (7)
I believe the answer is:
version
'it's one variety' is the definition.
(version is a kind of variety)
'vines or bubbly' is the wordplay.
'bubbly' indicates anagramming the letters.
'vines'+'or'='vinesor'
'vinesor' anagrammed gives 'VERSION'.
'of' is the link.
(Other definitions for version that I've seen before include "Something a little different - so riven (anag)" , "Model" , "Sort" , "Translation - personal account" , "Particular account of a matter" .)
