Do you need any cold brewing equipment?

Water quality

Always choose good water for making any tea – cold or hot. Water will have a lot of impact on the flavour. Use either fresh bottled spring water or filtered tap water. It should have a neutral flavour and be neither too hard nor too soft.

Water temperature

For making cold brewed tea, use either lukewarm or cold water, but never hot or hot boiled water. The temperature will impact the flavour and nutrient profile. If you steep it first in boiling water, even if it's for a minute, it won't be a cold-brewed tea anymore.

Steeping time

Steep your tea in the fridge for at least 2 hours, preferably longer. Green tea and white tea will take less time than black or darker oolong tea. For the best results, steep it overnight, regardless of the type. Black or dark teas, and herbal teas such as red rooibos and chamomile may be the best when steeped longer.

Black tea, lighter herbal teas, oolong teas and rooibos teas may need at least 8 hours to infuse. However, since flavour preferences are always personal, try your tea after steeping it overnight and infuse longer if needed.   

If you are unsure how long to cold brew your tea, leave it overnight.

Straining the leaves

If you plan to drink the tea within 24 hours, there's no need to strain it. You can simply pour the tea into the glass using a regular strainer. You can even top it up with more cold water.

How much tea to use

Use 2 tablespoons of loose tea per one litre of water or at least 3-4 tea bags. If you are using special cold brew blends, follow the instructions instead, as these blends are crafted specifically for this type of brewing. Did you notice that's exactly how much you would use for making 4 cups of tea?

Do you need condiments?

You don't need any condiments for cold-brewed tea as it won't be bitter, and it will be much lighter than a regular cup of hot tea. If you still want to use a sweetener, add it to your glass, not to a teapot. You can add different fresh fruits or herbs and steep them together with tea leaves.

Benefits of cold brew tea

One of the reasons why cold brew is enjoying so much attention are the potential health benefits. Until recently, all studies suggested that to extract the most catechins, caffeine and other compounds, the hotter the water, the better.

However, recent studies showed that the truth may be more complicated. In fact, cold brewing proved to be a better choice than hot brewing if the catechins are what you are looking for, but for black tea, the values won't be much different (1). Besides, cold brewing will extract less caffeine, which makes it even more convenient for making tea for all-day sipping, especially in spring and summer.

However, as always in the world of tea, there are exceptions. One study showed that after 12 hours of cold brewing, semi-ball shaped oolong (dong ding) released more caffeine and 4 times more catechins than when hot brewed (2). This actually showed that rolled oolong tea, if you don't mind waiting for 12 hours and some extra caffeine, may be better cold than hot brewed. However, there's a “catch”. Study tested rolled oolong brewed for 4 minutes at 85 degrees Celsius, which may not be enough for leaves to fully unfurl.
