Making Perfect Cup of Tea

How to make a perfect cuppa

Many people ask no more than that their tea be "wet and warm", but in the hunt for perfection in a tea cup, a scientist has created a formula for optimal temperature, infusion and imbibation. Oh, and when to put the milk in.

There are 11 rules for perfect tea making, rules from which nobody should dare depart, said George Orwell.

The great critic of Hitler and Stalin, was not above a bit of teatime Totalitarianism himself, it seems. Orwell said that tea - one of the "mainstays of civilization" - is ruined by sweetening and that anyone flouting his diktat on shunning the sugar bowl could not be called "a true tealover".

GEORGE ORWELL'S TEA RULES 

  1. Use tea from India or Ceylon (Sri Lanka), not China
  2. Use a teapot, preferably ceramic
  3. Warm the pot over direct heat
  4. Tea should be strong - six spoons of leaves per 1 litre
  5. Let the leaves move around the pot - no bags or strainers
  6. Take the pot to the boiling kettle
  7. Stir or shake the pot
  8. Drink out of a tall, mug-shaped tea cup
  9. Don't add creamy milk
  10. Add milk to the tea, not vice versa
  11. No sugar!

Aside from sweet-toothed tea drinkers, the author also displayed a distaste for scientists. So to mark the 100th anniversary of Orwell's birth, the Royal Society of Chemistry (RSC) has decided to look at his 11-point formula - and rubbish a good many of his supposedly "golden" rules.

Dr Andrew Stapley, a chemical engineer at Loughborough University, has brought the weight of his scientific knowledge (and shameless personal preferences) to bear on the question of the perfect cuppa, and found that Orwell was wrong on a number of points.

Orwell's six-spoons of tea per pot - mightily extravagant when the author set down this rule during post-war rationing - is still far too strong today. The RSC endorses no more than a single spoon of leaves.

As for adding milk to the tea after it is poured, the RSC issues a stern scientific warning against the practice. It seems that dribbling a stream of milk into hot water makes "denaturation of milk proteins" more likely. And who would want that?

"At high temperatures, milk proteins - which are normally all curled up foetus-like - begin to unfold and link together in clumps. This is what happens in UHT [ultra heat-treated] milk, and is why it doesn't taste as good a fresh milk," says Dr Stapley.

It is better to have the chilled milk massed at the bottom of the cup, awaiting the stream of hot tea. This allows the milk to cool the tea, rather than the tea ruinously raise the temperature of the milk.

Also, unlike in Orwell's rules, science seems to bear no grudge against those who would take sugar with their tea - provided it's white sugar.

Indeed, the addition of sugar is praised since it "acts to moderate the natural astringency of tea" - which translated into unscientific terms means that it makes tea, wait for it, less bitter.

This is heresy to Orwell. "Tea is meant to be bitter, just as beer is meant to be bitter," he said. What would he have made of the alcopop suggested by the RSC?

He would recognise and appreciate some elements of Dr Stapley's perfect cuppa. The RSC brew uses Indian Assam tea leaves, which falls within Orwell's tight stipulations. He said no other nation's tea made him feel "wiser, braver or more optimistic".

There is no real scientific reason for Assam winning out over other leaf varieties, it just happens to be a strong tea to Dr Stapley's own taste.

"While some things are backed by science, others - like the choice of Assam - are based on my own preferences. I'm sure there are going to be plenty of people coming up with better methods to make tea and it's good that we have that debate," says Dr Stapley.

Finally, the RSC recommends that the perfect cup of tea made by following its formula should be drunk while reading George Orwell's account of 1930s drudgery and vagrancy Down and Out in Paris and London.

Well, no disrespect to the late Mr Orwell, but BBC News Online begs to differ. Having brewed the perfect cup of tea, we recommend that you sip it while stewing over our tea break quiz.
