Map whining

I’ve seen this map several times on Twitter. It’s originally from a British company, ThirtyFifty. It gives a really nice idea of where the world’s wine regions are, and why, in terms of temperature.

There’s one problem, which is probably more obvious to New Zealanders than northern-hemisphere people. The latitude lines are wrong.

The 50N line and the equator are right, but the 30N line is a little too far north; the 30S line is a little too far north; and the 50S line is way too far north — it’s at about 45S, measured by the southern tip of Tasmania and the middle of NZ’s South Island.
