“Let’s start with coffee. Well, you might say, I like my coffee strong. There’s barely any water in there at all. Maybe… But what if I told you that in your tiny espresso there is 140 litres of water. Yes—140 litres. You might think I was slightly deranged. But that is the virtual water hidden in the coffee. That is the amount of water used in growing, producing, packaging, and shipping the beans that make the coffee.”
