White wine is palest somehow bottled in southeast (8)

'white wine' is the definition.
Both the definition and answer are singular nouns.
Perhaps there's an association between them I don't understand?

'palest somehow bottled in southeast' is the wordplay.
'somehow' indicates an anagram.
'bottled in' is an insertion indicator.
'southeast' becomes 'se' (synonyms).
