A cup of Assam tea is generally brewed within the following guidelines. For one cup of tea, use 1 level teaspoon or 2 grams per 8 fl oz. For a stronger brew, use more tea, do not increase brew time, as this will increase bitterness. For those who like their tea strong, you can double the amount of Assam tea used to 2 tsp or 4 grams per 8 fl oz.
