Tag: Heat and caffeine

According to the National Institutes of Health, caffeine is a colorless, odorless alkaloid that requires temperatures far exceeding water's boiling point to vaporize. This fact is key to understanding the science behind the question: does tea steam have caffeine? The answer, surprisingly, is no, and the reasons lie in fundamental chemical properties that differentiate the bitter compounds in your cup from the pleasant aroma that rises from it.

Caffeine is a notably heat-stable compound, meaning the high temperatures typically used for baking do not cause it to break down or dissipate. This means any matcha powder added to cookies, cakes, or muffins will retain its stimulant properties in the finished product.

According to chemistry experts, caffeine is a remarkably heat-stable molecule, requiring temperatures far beyond typical baking and cooking levels to break down. This simple fact means that yes, cooked espresso retains its caffeine content, transferring it to your culinary creations like brownies, cakes, and other desserts.
