The sun is out, the pavements are shimmering, and somewhere across the country someone is saying, “it’s too hot for tea.”
We’re here to tell you: it absolutely is not.
If you're searching for the best drink for a heatwave, rooibos might just be it, hot or cold. Here’s why.
Why Rooibos Is So Good in a Heatwave
Naturally caffeine-free (and that matters in hot weather)
Rooibos (pronounced roy-boss) is naturally caffeine-free.
Caffeine is a mild diuretic. It encourages your body to lose fluids. In a heatwave, when staying hydrated really matters, that’s not ideal.
Rooibos, by contrast, is naturally hydrating. Smooth, naturally sweet and completely free from caffeine and tannins, it’s an easy, drink-all-day option when the temperature climbs.
Supports your body when the heat ramps up
It’s also packed with antioxidants, including aspalathin, a polyphenol found only in rooibos, which help your body deal with oxidative stress in hot weather.
It won’t magically cool you down, but it does support your body while it’s working harder than usual.
Hot Rooibos in a Heatwave? Hear Us Out
It sounds counterintuitive, but hot drinks can actually help you cool you down.
Your body responds to a warm drink by increasing sweat production, and as that sweat evaporates, it takes heat with it. It’s the same reason people in some of the world’s hottest climates have been drinking hot tea for centuries.
Brew a cup of Original Rooibos, deep, malty, gently sweet, and let it do its thing.
Cold Rooibos: The Ultimate Summer Upgrade
Now for the really fun part.
Rooibos makes an absolutely brilliant iced tea, and it is far more forgiving than traditional tea.
Unlike black tea, it never goes bitter or cloudy when cooled, which makes it genuinely easy to prepare.
How to Make Iced Rooibos Tea
The short version? It could not be easier.
Brew it, cool it, pour it over ice and add whatever you fancy.
