Tea has been around since 2700BC and its popularity has spread around the globe becoming an important part of people’s daily lives. In 1946 George Orwell wrote an essay “A Nice Cup of Tea” laying down 11 steps to the perfect brew. The essay was a reaction to a lack of guidance on tea-brewing in cook books. “This is curious,” he wrote in London's Evening Standard, “not only because tea is one of the mainstays of civilisation in this country.., but because the best manner of making it is the subject of violent disputes.” His opinions began a debate that has caused acute controversy within the tea-etiquette world.
One can only speculate about the modern habit of making tea with a tea bag in a mug!
