How to Cold Brew Herbal Tea for Maximum Flavor

TL;DR: To cold brew herbal tea, combine 1–2 tablespoons of loose leaf herbal tea per 8–10 oz of cold, filtered water. Steep in the refrigerator for 6–12 hours, strain, and enjoy. Cold brewing produces a naturally smoother, sweeter flavor than hot brewing—with no bitterness and no heat required.

Hot tea has its place. But cold brewing herbal tea is something else entirely. The slow, low-temperature steep draws out complex flavors without the bitter edges that heat can introduce—leaving you with a clean, refreshing drink that's as good for unwinding as it is for staying hydrated.

Cold brewing also preserves the natural aromatic oils in loose leaf teas, so the flavors come through with remarkable clarity. No bitterness, no rush, no boiling water.

Why Loose Leaf Makes All the Difference

Not all tea cold brews equally. Bagged teas are typically made from lower-grade tea "dust" and fannings—the broken remnants left after whole leaves are processed. These fine particles release tannins quickly under heat, which is great for a fast cup but less ideal for a long, cold steep.

Loose leaf herbal teas, on the other hand, are made from whole or minimally processed leaves, roots, flowers, and botanicals. This means more surface area, more essential oils, and far more nuanced flavor. Tastings Tea loose leaf blends are crafted in small batches by artisan tea makers using all-natural, organic ingredients—resulting in bolder flavors, fresher aromas, and a richer cold brew experience than anything you'd find in a standard tea bag or bottled drink.

How to Cold Brew Herbal Tea: A Step-by-Step Guide

Cold brewing herbal tea is simple. Here's exactly how to do it:

1. Choose your loose leaf tea. Select a Tastings Tea loose leaf herbal blend suited for cold brewing (see recommendations below).
2. Measure your tea. Use 1–2 tablespoons of loose leaf tea per 8–10 oz of water. For a stronger brew, increase to 2 tablespoons.
3. Add cold, filtered water. Use cold or room-temperature filtered water for the cleanest flavor. Avoid tap water with strong mineral tastes, as this can affect the final result.
4. Combine in a jar or pitcher. Place your loose leaf tea directly into a glass jar, cold brew pitcher, or any container with a lid. Add your measured water.
5. Seal and refrigerate. Cover the container and place it in the refrigerator.
6. Steep for 6–12 hours. Herbal infusions generally benefit from a longer steep—aim for at least 6 hours, or leave overnight for maximum depth of flavor.
7. Strain and serve. Pour your finished cold brew through a fine mesh strainer or tea strainer into a glass over ice. Enjoy as-is, or sweeten lightly with honey if desired.

Getting the Ratios and Timing Right

The ratio and steeping time are the two factors that have the biggest impact on your cold brew's flavor. Here's a quick reference guide:

• Standard cold brew: 1 tbsp loose leaf per 8 oz water, steeped 6–8 hours
• Bold cold brew: 2 tbsp loose leaf per 8 oz water, steeped 8–12 hours
• Large batch (pitcher): 4–6 tbsp loose leaf per 32 oz water, steeped overnight

Unlike hot brewing, cold brewing herbal teas is forgiving—steeping for an extra hour or two won't turn your drink bitter. That makes it ideal for overnight prep.
