How to Cold Brew Tea: A Simple Step-by-Step Guide
Short answer: To cold brew tea, add 1 tea bag (or 1 tablespoon of loose tea) per 16–20 oz of cold filtered water, then refrigerate for 8–12 hours. Remove the tea, pour over ice, and enjoy. No boiling, no bitterness, no added sugar needed.
Cold brewing is the easiest way to make smooth, refreshing iced tea at home. Because the tea steeps slowly in cold water, it extracts less bitterness and tannin than hot brewing — resulting in a naturally sweeter, mellower cup. Here is everything you need to know.
What is cold brew tea?
Cold brew tea is tea that is steeped in cold or room-temperature water over several hours, rather than being brewed with hot water. This slow extraction draws out flavor and natural sweetness while leaving behind much of the bitterness, making it ideal for iced tea and fruit tea blends.
How do you cold brew tea? (Step by step)
- Choose your tea: Use cold-brew-friendly blends like green, black, or fruit teas. CloudyTree Tea's cold brew tea collection is designed specifically for cold steeping.
- Measure: Use 1 tea bag (or 1 tablespoon loose tea) per 16–20 oz (500–600 ml) of cold filtered water.
- Combine: Place the tea and water in a pitcher, jar, or bottle. A sealed glass bottle works perfectly and keeps it mess-free.
- Steep: Refrigerate for 8–12 hours (overnight is ideal) at around 4°C.
- Serve: Remove the tea bag or strain the leaves, pour over ice, and enjoy. Add fruit or citrus for extra flavor.
What is the best tea-to-water ratio for cold brew?
A good starting ratio is 1 tea bag per 16–20 oz of water. If you prefer a stronger cup, use slightly more tea or steep a little longer. Because cold brewing is gentle, it is hard to over-steep — but removing the tea after 12 hours keeps the flavor clean and fresh.
How long should you cold brew tea?
Most teas are ready in 8–12 hours. Lighter green teas can be ready closer to 6–8 hours, while black and fruit teas benefit from a full overnight steep. Hibiscus develops its color and tartness faster than most blends.
Why does cold brew tea taste smoother?
Hot water rapidly extracts tannins and caffeine, which create bitterness. Cold water extracts these compounds much more slowly, so cold brew tea tastes naturally smoother and sweeter — without needing sugar. This is why cold brewing is perfect for naturally flavored fruit teas.
Frequently Asked Questions
Can you cold brew any tea?
Most teas can be cold brewed, but blends designed for cold steeping extract best. Green, black, white, and fruit teas all work well; very delicate teas may need a longer steep.
Do you need to boil water first for cold brew tea?
No. The whole point of cold brewing is skipping the boil. Just use cold filtered water straight from the fridge or tap.
How long does cold brew tea last in the fridge?
Cold brew tea keeps for up to 3–4 days in a sealed container. Remove the tea bag after steeping to prevent over-extraction.
