The government could also just pile it up in the town squares of France, as freebies from the EU for everyone. Would be gone in a day. Seems strange to “destroy it” when the public will do it for free and it’s been subsidised and paid for. Unlikely I realise, but it’s not like wine goes off. Maybe they need the space for the next load of wine they’re going to cellar and then destroy…
Plus the article says the alcohol from the destroyed wine can be reused - seems like a bit of an effort to go through given the alcohol content of around 12%.
