With instant coffee, caffeine measurements are based on the amount of the instant coffee powder used to make the drink.

Here's how some popular instant coffees compare

The caffeine content of coffee itself varies enormously. According to the USDA*, 1 rounded teaspoon of instant coffee (1.8 grams in weight) contains 57 mg of caffeine. No matter how much water, milk, or creamer you add to the coffee - the amount of caffeine will remain the same. Barone and Roberts* quote a value of 40-108 mg per 150 ml.

This shows that people vary the amount of coffee powder they use for their drink. The strength and flavor are greatly influenced by the amount of water mixed with the coffee powder.

Instant coffee is made by roasting and grinding the coffee bean and then extracting the flavor. This is done by placing the coffee in a solution of water and then dehydrating the solution (by freeze drying).

Some instant coffee brands are using micro-ground coffee to boost flavor and caffeine. This is the process Starbucks Via uses.
