When the weather is hot, there is nothing quite like a refreshing glass of cold brew tea! While cold brewing seems simple, there are actually a few tips and tricks to keep in mind; otherwise, the flavor might fall short, or it could even pose potential health risks. Here is a breakdown of the pros, cons, and important precautions for making cold brew tea.
Pros and Cons of Cold Brew Tea
| Pros | Cons |
|---|---|
| Convenient and Easy: Simply add cold water and place it in the refrigerator. | Takes Time: You need to wait 4–8 hours before drinking. |
| Preserves Natural Flavors: Low-temperature extraction creates a smoother, naturally sweeter tea. | Not Ideal for All Leaves: Compressed teas may not fully release their flavor profile. |
| Lower Caffeine: Reduces the risk of sleeplessness, making it safe to enjoy in the evening. | Less Energy Boost: Lower caffeine content means it won’t wake you up as effectively as hot tea. |
| Cooling and Quenching: Perfect for summer days and a fantastic way to beat the heat. | Prone to Spoilage: Can sour or grow bacteria in high summer temperatures, so it must be refrigerated and consumed promptly. |
Is Cold Brew Tea Toxic?
A common rumor is that steeping cold brew tea for too long will leach pesticides out of the leaves, making it toxic. This is simply not true! The Tea Research and Extension Station (TRES) in Taiwan has conducted experiments showing that most Taiwanese teas use fat-soluble pesticides, which are insoluble in water. Therefore, even with extended steeping, pesticides will not dissolve into the liquid. In other words, you can enjoy your cold brew completely worry-free—drink up and enjoy!
Drawbacks and Precautions of Cold Brew Tea
While cold brewing is convenient and yields a sweet, mellow taste, not all teas are suitable for it. For instance, heavily roasted oolongs struggle to release their aromas in cold water, while post-fermented pu-erh teas present potential microbial and bacterial concerns, making them less than ideal for cold brewing. If you want to try making cold brew, we recommend choosing light-fragrance oolong tea, green tea, or white tea for the best results!
