In the category of Oolong tea, the drinking experience of cold brewing is that lightly fermented and lightly roasted teas are suitable for cold brewing. Heavy fermentation and heavy roasting teas are not suitable for cold brewing.
Therefore, I strongly recommend not cold brewing Oolong tea in summer. Some tea lovers think that cold brewing Oolong tea in summer makes them feel too hot, so they should drink Oolong tea in autumn. Moreover, as a tea that is constantly transforming, some Oolong teas are not ideal in summer.
In the category of Oolong tea, I recommend cold brewing of Taiwan Oolong first. Most Taiwan Oolongs taste good when cold brewed, but there are exceptions, such as the traditional Dongding Oolong and Muzha Tieguanyin, which have a bit of awkward flavor when cold brewed, which is still due to their heavy fermentation and roasting.
Phoenix Dancong Tea is generally less fermented and roasted than Oolong tea, but higher than Taiwan Oolong. I think most Phoenix Dancong Tea is not suitable for cold brewing. If you force cold brewing, it won't be too bad to drink, but it's just boring.
It is better to choose Phoenix Dancong Tea with lighter fermentation and roasting for cold brewing.
In terms of the specific parameters of cold brewing, Phoenix Dancong Tea is a little different from green tea, yellow tea, and flower tea Taiwan Oolong.
The tea-water ratio can be smaller. It doesn't have to be 1:100, and the amount can be reduced by half.
The cold brewing time needs to be increased. It is recommended to cold brew at room temperature for more than 6 hours, and refrigerate for more than 3 hours. It can be overnight, but not more than 12 hours.
The following takes Yashi Duck Shit with lighter fermentation and roasting as an example to show the operation of three types of cold brewing.
- The most common. Note that the tea-water ratio is about 1:200. If you cold brew at room temperature, the time will double.
- The simplest way to operate cold brew. Just use an ice box. If you want a better cold brew effect, you can buy a special cold brew pot, which is compatible with coffee cold brew pots. The ratio of tea to water is about 1:100.
- Semi-cold brewing method, which is relatively rare. It is suitable for tea lovers who want cold brewing but want to shorten the time and drink it quickly.
The principle of semi-cold brewing is to release the flavor substances of the single cluster as much as possible through hot brewing, and then add ice cubes to quickly lock the aroma and taste while cooling down.
