How many calories are in coffee with dextrose and maltose as some of the ingredients?
There is not enough information to answer this question, as we don’t know what amount of coffee you are talking about and how much of each sweetener is added. The answer could be anything from some fraction of a single calorie to essentially infinity. Generally, however, a plain cup of coffee has around 2 calories per cup. Dextrose and Maltose have between 12-16 calories per teaspoon, depending which random nutritional website you choose to believe.
