The standard tea infusion time is four minutes
The tea to water ratio determines the intensity of the tea. One tea bag is sufficient for one mug of hot water. To be more specific, the flavors of one teabag can be maximized with 140 ml water while two teabags can flavor a teapot of 200 to 250ml water. If using loose tea, 2.5 grams or one tea spoon is equivalent to one tea bag.
