When the heat rises, nothing beats a chilled glass of something refreshing. While iced tea is a summer classic, cold brew tea has quietly become a favourite for those who want a smoother, more refined taste. But what makes it special, and why is it ideal for summer? Let’s explore the science behind cold brew and its seasonal appeal.
What Is Cold Brew Tea?
Unlike traditional tea brewed with hot water, cold brew tea is made by steeping tea leaves in cold or room-temperature water for 6–12 hours. This slow infusion extracts the flavours gradually, resulting in a cleaner and less bitter brew.
Why does this happen? Heat extracts tannins and caffeine quickly, which can make tea taste sharp or astringent. Cold water is gentler, drawing out sweeter notes and leaving harsh compounds behind. The result is a mellow, flavourful tea with a naturally smooth finish that's gentle on the palate.
Healthier and More Refreshing
One big reason for its growing popularity is health. Cold brewing helps preserve antioxidants like catechins, especially in green tea. These natural compounds help boost immunity, aid digestion, and promote healthy skin. It also contains less caffeine than hot tea, making it perfect for a gentle pick-me-up on hot days.
Best of all, it’s low in calories and needs no added sugar to taste good, ideal if you’re looking for refreshing drinks that hydrate and energise without any guilt.
Summer’s Best Kept Secret
In summer, we naturally seek lighter and chilled beverages. That’s why cold brew tea is quickly being recognised among the Best Drinks for Summer. It hydrates, soothes and pairs beautifully with herbs, fruits and florals. Use it as a base for some of the best summer mocktails — like hibiscus tea with berry or lemon and mint, or jasmine green tea with cucumber and basil.
Cold Brew vs Iced Tea
Cold brew tea and iced tea may seem similar, but they’re brewed in entirely different ways. Iced tea is made hot, then cooled, which can leave it tasting strong in flavour. Cold brew skips the heat altogether, making the final brew naturally smooth and balanced.
