The world’s largest cork tree, Alentejo - Portugal. 230+ years old, producing corks since 1820. It was 5 years old when the first English settlers arrived in Australia, and 6 years old when the French Revolution began in 1789. 1789 bottles of wine sealed with cork in that same year were fairly recently discovered in a French cellar, and both the wines and corks in good condition. Every nine years producing 1T of bark, enough cork for 100,000 wine bottles, weights 102T.
