I saw this and thought it interesting :) I've been watching a fair few buy-a-farm-in-southern-europe vloggers pick their own vines and olives, but now realise none of them seem to talk about making vinegar. What I long for, but can't find in any supermarket on the continent, is Malt Vinegar. Malt vinegar is the mainstay vinegar in the UK and absolutely essential for the classic fish and chips. Yet it doesn't seem to be widely available outside the UK?
