The Perfect Cup: How to Cold Brew Green Tea

Cold Brew Green Tea

I’m so excited to share one of my favorite tea preparation methods with you today – cold-brewing green tea! I’ve experimented with various cold brew methods over the years and have honed the perfect technique to achieve a refreshing, flavorful, cold-brew green tea anytime.

Fresh green tea

Why Cold Brew?

Cold brewing is a great way to enjoy the health benefits of green tea without the bitterness that can come from hot brewing.

Cold brewing also allows you to make a large batch of concentrated tea that will keep in the fridge for up to two weeks. So you can enjoy fresh, cold-brew green tea whenever you like with just a splash of the concentrate. It’s so convenient!


How to Make Cold-Brew Tea

Supplies needed:

  • Green tea leaves (loose-leaf or bagged)
  • Large mason jar or pitcher
  • Fine mesh strainer or tea/coffee filter


  1. Start with a ratio of 1/4 cup of loose-leaf tea or 4 green tea bags per 4 cups of water. Adjust amounts as desired for a stronger or milder tea concentration.
  2. Bring water to a rapid boil, then let it cool down to room temperature. This allows you to start with fresh, oxygenated water.
  3. Place tea leaves or bags into a large mason jar or pitcher. Pour the room-temperature water over the tea.
  4. Let the tea steep at room temperature or in the refrigerator for 8–12 hours. I like to start steeping in the evening and let it brew overnight.
  5. Once brewed, strain the tea through a fine mesh strainer or tea/coffee filter to remove all leaves.
  6. Enjoy cold-brew green tea straight over ice or store it in the fridge for up to 2 weeks.

To serve: For hot tea, gently reheat the concentrate on the stove or microwave. For iced tea, pour 1 part concentrate over 1 part water or ice. Adjust the ratio to taste. Add fresh mint or lemon, if desired.
