Etna Sicily
Wine reflects the place it comes from, and some of the world’s most fascinating wines are born in regions where natural conditions push human limits. From the steep slopes of active volcanoes to the wind-swept corners of Northern Europe, these extreme terroirs stretch the boundaries of viticulture. They challenge both the vines and the people who tend them, but the reward is wines that are distinctive, expressive, and truly memorable.
Here’s a look at ten of the world’s most extreme wine regions, where altitude, soil, climate, and sheer determination converge to create truly exceptional wines.
