If prioritizing both maximum smoothness and high safety, which brewing technique is recommended over sun tea, which carries the highest risk?
Refrigerator cold brew, which maintains a consistent low temperature.
When balancing the desire for a smooth flavor profile—often achieved through slow, cool extraction—with the paramount concern of food safety, the refrigerator cold brew method stands out as the superior choice compared to sun tea. Refrigerator cold brew operates at a consistent low temperature, typically between 35°F and 40°F. This temperature keeps the mixture safely outside the bacterial danger zone (40°F–140°F) for its entire long steeping cycle (8–16 hours). This results in a brew that is both very safe and characteristically smooth with low bitterness. Sun tea, despite offering a unique flavor, spends critical time in the danger zone, thus placing it at the highest risk category among the three primary methods.
