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.
