Cold Brew Ceylon Tea: A Complete Guide
Cold brewing unlocks a naturally sweet, smooth dimension of Ceylon tea with no bitterness — and it couldn't be simpler.
Hot-brewed tea poured over ice is perfectly fine. Cold-brewed Ceylon tea is something altogether more interesting. The slow, cold extraction unlocks natural sweetness and soft, round flavours while leaving the harsh tannins largely behind. The result is a refreshing, smooth tea that needs little or no sweetener.
The Science Behind Cold Brew
Heat extracts tannins and bitter compounds quickly. Cold water extracts them far more slowly — but it extracts the aromatic compounds and natural sugars just as effectively, given enough time. The resulting liquor is lower in tannins, higher in natural sweetness, and gentler on the palate. It also contains slightly less caffeine than hot brew, which some people prefer.
Method 1: Overnight Fridge Brew (Recommended)
- Add 10–12 g of loose-leaf Ceylon tea (any grade) to 1 litre of cold, filtered water.
- Cover and refrigerate for 8–12 hours (overnight is ideal).
- Strain through a fine-mesh sieve or tea filter.
- Serve over ice. Keeps refrigerated for up to 4 days.
Method 2: Short Cold Brew (4–6 hours)
Use slightly more leaf (12–15 g per litre) and taste after 4 hours. Continue until the desired strength is reached. This method works well for busy days when you forgot to set it up the night before.
Which Grade Works Best?
- Whole-leaf (OP, OPA): Produces a light, floral, slightly citrusy cold brew — elegant and delicate.
- Broken-leaf (FBOP, FBOPFEXSP): Brews darker and stronger — excellent as a base for iced tea cocktails or with citrus and mint.
Add a slice of lemon, a sprig of fresh mint, or a cinnamon stick for a natural flavour lift. The cold brew makes the perfect base for Ceylon iced tea lemonade.
