An entire country's wine industry was selling the wrong grape for over a century, and didn't find out until a DNA test said so.

A warming climate, unusually long summer daylight, and a grape bred for exactly this problem — how Denmark, Sweden and Norway ended up making genuinely good wine.

France's old bulk-wine engine room reinvented itself with science and scale rather than tradition — the opposite instinct to Bordeaux and Burgundy, without leaving the country.

Same chalk, same grapes, same method as Champagne — just a few hundred miles north, and only ripening properly since the climate warmed up.
