Yes. However, the cold brewing process, which is common with other teas and coffees, takes 16-24 hours to steep. The process doesn’t seem to extract any additional benefit compared to the other methods mentioned and thus we typically don’t recommend it. But if you prefer cold brewing it is certainly safe and effective for chaga tea.
In addition, you can use the brewing methods mentioned above and allow the chaga tea to cool to the temperature you prefer.
