This is notable because it's in an unheated greenhouse. Lots of botanical gardens around the world, like the Brooklyn Botanical Gardens in NYC, have fruit-bearing cacao trees in their (heated) tropical rooms.
In greenhouses also in South of Spain. With climate change roaring, more places in the North will be able to culture that. It takes a lot of time to grow and some talent to obtain the fruit but it could be possible. I bet that it tastes 1000 times better than the processed cacao.
The tree can not stand long periods of temperatures below 15 Celsius.

It does not. Cacao beans/seeds taste utterly vile. You couldn't imagine in your wildest dreams that the chocolate you buy in stores comes from those disgusting things.
There was a cacao plantation on the side of the road that I walked past every day after school when I was between 5 and 14yrs old. I'd always pick a few on the way home to break open a pod and suck on the beans. But if you accidentally bit into one, well /* insert face vomiting emoji */
