Scientists have established the perfect formula for a perfect brew of tea. They have determined that tea is best if you drink it six minutes after it has been made. The ultimate brewing time is two minutes and the idea amount of milk for those who like to add to their cup of tea is 10 ml (.338 oz.) per cup.

Many of us know that brewing tea is considered an art, but apparently making the perfect mug of tea is all down to a science. Many researchers have devised a mathematical formula for the idea brew of tea, which shows that it is best if you drink your cup of tea six minutes after being made. The optimum brewing time is two minutes.

A team of university researchers has devised a mathematical formula for the ideal brew of tea. The formula is:

TB + (H2O at 212f (100c) degrees) 2 minutes BT + C (10ml) 6 minutes BT = PC at OT 140f (60 c) degrees).

TB = Tea Bag

BT = Brewing Time


PC = Perfect Cup

OT = Optimum Temperature

The perfect drinking temperature of 140f (60c) is achieved six minutes later – but after 17 minutes and 30 seconds the tea will be past its best as it falls below 112f (45c) degrees.

For the research, the team spent 180 hours in the lab testing brewing methods, and a panel of volunteers consumed 285 cups of tea.

Researchers found that “ when enjoying a cup of tea, our palette requires a balance between bitterness and sweetness.”

Other findings show that adding milk or cream allows the ability to balance natural bitterness and allow a smoother taste sensation.

The optimum temperature to drink tea is 140f (60c) degrees. Waiting six minutes for tea to reach 140f (60c) degrees avoids the risk of scalding, yet still allows us to enjoy the full flavors and aromas in your cup of tea.

The best brewing time for teas are:

Green Tea 2-3 minutes

Black Tea 3-5 minutes

White Tea 1-3 minutes

Herbal Tea 5-8 minutes

Oolong Tea 3-5 minutes

The amount of tea recommended for a 12 oz cup is one tea bag which contains 2g of tea (about 1 tsp). Some brands contain less.

For loose leaf tea use around 1 1/2 teaspoons (3 – 3 1/2g) I notice some instructions call for 7-8g for 8oz of water. That would mean using 10-12g (5-6tsp) for a 12oz mug.

A perfect brew can be reached at the convenience of making it in a Tea Totaler. The Tea Totaler has all the tools you need to pour your hot water, infuse, ability to discard and store additional tea for another serving in one.
