Beverages, Tea, Black, Ready To Drink: How Many Grams in a Cup?
Ready-to-drink black tea is an unsweetened or minimally sweetened brewed black tea packaged for direct consumption. At 1.000 g/ml — exactly water density — this product has essentially no dissolved solids relative to water at standard measurement precision. A cup weighs approximately 237 g; a tablespoon weighs about 14.8 g. Like brewed coffee, it functions as a water substitute by gram weight in any recipe context. Used in tea-infused baked goods (Earl Grey cakes, chai pancakes), in braising liquids, and as a low-calorie beverage. If sweetened RTD tea is used instead, the density may rise to 1.04–1.06 g/ml due to added sugars.

FAQ
- Why does ready-to-drink black tea have exactly water density?
- Unsweetened brewed tea contains only trace dissolved tannins, polyphenols, and caffeine — collectively less than 0.5 g per 237 ml cup. At such low concentrations, the density rounds to 1.000 g/ml at any practical measurement precision. The 1.000 value is the expected result for any nearly-pure water-based beverage.
- Does sweetened RTD tea weigh more than unsweetened per cup?
- Yes. Sweetened ready-to-drink teas typically contain 20–30 g of sugar per cup. Sugar (sucrose, ~1.59 g/ml) dissolved at these concentrations raises density to approximately 1.04–1.07 g/ml, adding 10–15 g per cup compared to unsweetened. Always check the nutrition label: if a tea has more than 5 g of sugar per serving, its density and gram weight will differ meaningfully from this unsweetened entry.
