Beverages, Coffee, Instant, Decaffeinated, Prepared With Water: How Many Grams in a Teaspoon?
Prepared decaffeinated instant coffee is a brewed-strength liquid beverage with a density of 1.011 g/ml, barely above pure water. One US cup weighs approximately 239 g and one tablespoon about 14.9 g. The near-water density reflects the fact that a standard cup of prepared instant coffee contains only 1-2 g of dissolved coffee solids in 237 ml of water -- the solute concentration is so low that the liquid behaves almost identically to water in mass and flow. The decaffeination process removes at least 97% of the caffeine from the coffee beans before they are brewed and dried into instant form. This prepared beverage is used directly for drinking or as a liquid ingredient in recipes calling for brewed coffee, such as tiramisu, coffee-flavored glazes, or braising liquids.

FAQ
- Is prepared decaf instant coffee interchangeable with regular brewed coffee by volume in recipes?
- By weight and volume, yes -- both are essentially water with trace dissolved solids, and both weigh approximately 239 g per cup. The flavor intensity of instant decaf may be slightly lower than drip-brewed coffee, so some recipes benefit from using a slightly stronger concentration (an extra half teaspoon of powder per cup) to match the flavor impact.
- Does prepared instant decaf coffee weigh differently than prepared regular instant coffee?
- The difference is trivial. Regular prepared instant coffee has a density of 1.008 g/ml (238 g/cup) versus 1.011 g/ml (239 g/cup) for decaf. The 1 g per cup difference is within the margin of error for any kitchen measurement and has no practical significance in cooking or baking.
