The Cool Revolution: What is Cold Brew Tea?
The secret to this new wave of iced tea lies in one simple change: turning down the heat. Unlike traditional iced tea, which is brewed hot and then cooled, cold brew tea is made by steeping loose tea leaves in cold or room-temperature water for an extended
period, typically between 8 to 12 hours. This slow-infusion method is a game-changer for flavour. When tea leaves are subjected to hot water, they release tannins more quickly, which can lead to a bitter or astringent taste. The cold brew process, however, is much gentler, extracting the tea's nuanced flavours while leaving many of the bitter compounds and a significant amount of caffeine behind. The result is a remarkably smooth, naturally sweeter tea that is less acidic and easier on the stomach.
Tulsi: The Queen of Herbs Takes Centre Stage
At the heart of this trend is Tulsi, also known as Holy Basil. Revered in India for millennia and a cornerstone of Ayurveda, Tulsi is celebrated for its spiritual significance and extensive wellness properties. It is considered an adaptogen, an herb believed to help the body cope with physical and psychological stress. Beyond its benefits, Tulsi brings a unique flavour profile to the cup—a complex blend of peppery, and sometimes clove-like notes that is both aromatic and invigorating. By cold-brewing Tulsi with high-quality loose-leaf teas, cafes are creating a beverage that is not only refreshing but also deeply rooted in Indian tradition, offering a moment of calm and clarity in every glass.
Beyond Lemon and Mint: A World of Flavour
While Tulsi is a star player, the new iced tea movement is all about creative experimentation with a wide array of fresh herbs. Baristas and tea enthusiasts are moving beyond the standard slice of lemon to explore pairings that add complexity and aroma. Each combination offers a unique sensory experience, transforming a simple drink into a sophisticated beverage. These thoughtful pairings are designed to complement the natural character of the tea, whether it's a robust black tea or a delicate white tea.
Pairings to Inspire Your Palate
The possibilities for flavouring cold brew tea are nearly endless, but some pairings have emerged as modern classics. Lemongrass & Green Tea: This is a match made in wellness heaven. The bright, citrusy notes of lemongrass blend beautifully with the grassy, earthy flavour of green tea, creating a crisp and uplifting drink. It's known to be great for digestion and provides a clean, refreshing finish. Rosemary & Black Tea: The pine-like, savoury aroma of fresh rosemary offers a surprising yet delightful counterpoint to a bold black tea like an Assam or Earl Grey. The result is an infusion that is both grounding and aromatic, perfect for an afternoon pick-me-up. Lavender & White Tea: For a more delicate and calming experience, the floral, slightly sweet scent of lavender is paired with the subtle, nuanced flavour of white tea. Because white tea is the least processed tea, its gentle character provides the perfect canvas for the soothing properties of lavender, making it an ideal choice for winding down.
How to Make Your Own Cold Brew
Embracing this trend at home is surprisingly simple. You don’t need any fancy equipment—just a pitcher, good quality loose-leaf tea, fresh herbs, and some patience. Start with a ratio of about 10 grams of loose-leaf tea per litre of filtered water. Add your tea and chosen herbs (like a handful of fresh Tulsi leaves or a sprig of rosemary) to a large jar or pitcher. Pour cold or room-temperature water over the top, stir gently, cover, and let it steep in the refrigerator for 8 to 24 hours. The longer it steeps, the stronger the flavour will be. Once it's ready, simply strain the leaves and herbs out, and you'll have a pitcher of smooth, flavourful iced tea ready to enjoy.
