What temperature range is typically associated with a slow cooker set to its lowest 'warm' setting when mimicking sun tea infusion?

Around $160^\circ\text{F}$ to $170^\circ\text{F}$

An alternative method suggested for tea drinkers who want the smooth flavor profile of sun tea without the inherent risks associated with prolonged time in the bacterial danger zone involves using a controlled heat source like a slow cooker. When utilizing this approach to mimic the slow infusion, the slow cooker is generally set to its lowest available 'warm' setting. This setting typically maintains temperatures in a controlled range of around $160^\circ\text{F}$ to $170^\circ\text{F}$. This precise, consistent heat allows for the flavor extraction to occur over a much shorter timeframe, usually around four to six hours, providing a reliable environment that bypasses the uncertainty related to weather and sun angle.
