Why Cold Brewing Creates Better Iced Tea

01
Cold brewing extracts flavor compounds slowly and gently, avoiding the harsh tannins and bitter elements that emerge with hot water. Unlike hot-brewed tea that becomes bitter when cooled, cold brew tea maintains its smooth character and can be stored in the refrigerator for days without degrading.

Key Advantages

No Bitterness

Cold water can't extract harsh tannins that cause bitter flavors, resulting in a naturally smooth brew.

Natural Sweetness

Gentle extraction preserves tea's inherent sweetness, often eliminating the need for added sugar.

Set & Forget

No timing pressure—it's virtually impossible to over-steep cold brew tea.

Extended Storage

Properly refrigerated cold brew stays fresh for 3-5 days without losing quality.

Basic Cold Brew Method

02

Step 1: Choose Your Tea

Almost any tea can be cold brewed, but some work better than others. Green, white, and herbal teas are ideal, while black teas need careful timing.

Best Choices:

  • Green teas: Sencha, jasmine, gunpowder
  • White teas: Silver needle, white peony
  • Herbal teas: Mint, chamomile, fruit blends
  • Oolongs: Light, floral varieties

Step 2: Measure Tea and Water

Use more tea than you would for hot brewing—about 1-2 tablespoons of loose tea per 8 ounces of water. Cold brewing is forgiving, so err on the generous side.
StrengthAmountProfile
Light brew1 Tbsp per 8ozDelicate, subtle flavor
Medium brew1.5 Tbsp per 8ozBalanced strength
Strong brew2 Tbsp per 8ozFull-bodied, intense

Step 3: Combine and Steep

Add loose tea to cold or room temperature water in a pitcher or jar. Stir gently to ensure all tea is wetted, then refrigerate for 6-12 hours.

Timing Guidelines:

  • Green/White teas: 6-8 hours
  • Oolong teas: 8-10 hours
  • Black teas: 6-8 hours (watch carefully)
  • Herbal teas: 8-12 hours

Step 4: Strain and Serve

Strain out all tea leaves using a fine mesh strainer or cheesecloth. Serve over ice immediately or store in the refrigerator for later use.

Storage Tip

Cold brew tea stays fresh in the refrigerator for 3-5 days. Store in a covered container to prevent absorption of other flavors.
