Cold Brew Thai Tea

Brew LabยทUpdated June 2026
Cold brewed Thai iced tea

Cold brewing trades speed for smoothness. A long, cold steep pulls flavor and aroma while leaving harsh tannins behind - so the tea is rounder, less bitter, and forgiving of a long sit over ice.

Why cold brew Thai tea

The method

  1. Combine. Add 6 tbsp Thai tea mix to 4 cups (1 L) cold, filtered water in a jar.
  2. Steep cold. Cover and refrigerate 12 hours (8 minimum, 16 for bold).
  3. Strain. Pour through a cloth filter sock or fine mesh lined with a coffee filter.
  4. Sweeten. Stir in sweetened condensed milk to taste while the concentrate is still smooth.
  5. Serve. Fill a glass with ice, pour, and float evaporated (or oat) milk on top.
Tip: sweeten per glass, not the whole jug, so you can keep an unsweetened batch fresh for up to 4 days.

FAQ

Can I cold brew the same mix used for hot Thai tea?

Yes. The standard ChaTraMue-style mix cold-brews beautifully - just use a bit more mix to compensate for the gentler extraction.

How long does cold-brew Thai tea last?

Unsweetened concentrate keeps 3-4 days refrigerated. Once milk is added, drink within a day.
