Wine country including even parts of rift valley (5)
I believe the answer is:
italy
'wine country' is the definition.
'italy' can be an answer for 'country' (Italy is an example). I'm not certain of the 'wine' bit.
'even parts of rift valley' is the wordplay.
'even parts of' indicates alternate letters (the letters in even-numbered positions).
'rift'+'valley'='riftvalley'
The alternate letters of 'riftvalley' are 'ITALY'.
'including' acts as a link.
Can you help me to learn more?
(Other definitions for italy that I've seen before include "Land for laity, oddly" , "Country of southern Europe" , "Latin country" , "Problematical (informal)" , "Rome is its capital" .)
