What analytical term is helpful for viewing brewing duration in relation to starting and peak water temperatures?
Answer
Delta T
For a more precise understanding of the brewing dynamics, it is helpful to analyze the brewing duration in relation to the *delta T*, which represents the difference between the starting water temperature and the peak temperature ultimately reached within the sun-exposed jar. A large difference (high delta T, meaning the water started cold but got very hot) suggests rapid heat transfer and potentially shorter required steep times once sufficient heat is achieved. Conversely, a small delta T—such as starting with cool tap water ($55^\circ\text{F}$) when the air is only $80^\circ\text{F}$—indicates prolonged time spent at moderate, unsafe temperatures, increasing bacterial risk despite long exposure.
