Wine is made from fermented grapes by definition.
Same as mead is made from fermented honey, kumiss is made from fermented mares' milk, kvass is made from fermented bread, and cider is made from fermented apples.
Wine made with other produce does exist: You can buy cherry wine and blueberry wine. But the market for them is tiny. They’re seen as a novelty and not taken seriously within the industry. - Being classed as 'novelties', we don't (yet) have standard definitions for those alcoholic drinks made from blueberries, etc. So we tack the word 'wine' on as a temporary fix.
I propose that henceforth cherry wine be defined as "Blush", and blueberry wine be defined as "Blurg".
"Have a glass of blush". "No I prefer to drink blurg".
