How to Cold Brew Loose-Leaf Tea in the Refrigerator

Cold brewing means steeping loose-leaf tea in cold drinking water inside the refrigerator. It is a brewing method rather than a separate type of tea, and the result depends on the leaf, water, amount and time you choose.

A Simple Refrigerator Method

1. Use a clean, covered pitcher or jar and fresh drinking water.
2. Add loose-leaf tea. Start with the amount you normally use for the same volume of hot tea.
3. Keep the container in the refrigerator and begin tasting after two hours.
4. Strain the leaves when the tea tastes clear and balanced.
5. Serve cold. Add ice only if you want a colder or lighter cup.

Leaf size and tea style change the extraction speed, so taste is a better guide than one fixed steeping time.

Adjust One Variable at a Time

• If the tea tastes thin, add more leaf on the next batch.
• If it tastes harsh, strain earlier before reducing the leaf amount.
• If the aroma seems muted, compare the same tea with different water.

Keeping notes on leaf amount, water and tasting time makes the result easier to repeat. Our water guide for tea brewing explains how water can change aroma, texture, bitterness and sweetness.

Cold Brew Tea vs. Iced Green Tea

This page covers the general refrigerator method for loose-leaf tea. If you specifically want green tea served cold, use our green tea for iced tea guide, which compares cold brewing with brewing hot tea directly over ice.

Choose Tea Without Guessing at Product Facts

Different tea categories can be tested with the same basic method, but each leaf should be tasted on its own terms. Browse the current tea collection for available sizes and product-specific preparation notes.

Keep the Process Clean and Cold

Use clean equipment, keep the tea refrigerated while it steeps, and strain it into a clean container. Cold brewing does not make unsuitable water safe. If the tea develops an unusual smell or appearance, discard it.

Make the Next Batch More Repeatable

Start with one tea, taste it at intervals, and record when it reaches the balance you prefer. Change only one variable for the next batch.
