Best Teas & Gear for Cold Brewing (2025 Review)

Summer is coming, and you need to stop making bitter iced tea. We tested the top bottles, pitchers, and tea blends designed specifically for cold extraction.

Material Warning: Glass vs. Plastic

We strongly recommend Glass bottles (like Hario) over Plastic for cold brewing. Tea is acidic and easily absorbs odors. Cheap plastic pitchers can stain and hold onto "stale fridge smells" that ruin delicate teas.

Part 1: The Gear (Bottles & Pitchers)

Best Overall (Cold Brew)
Hario Filter-in Bottle

1. Hario Filter-in Bottle

★★★★★ (The Industry Standard)

Walk into any specialty tea shop in Tokyo, and you will see this bottle. The Hario Filter-in Bottle is designed to look like a wine bottle, making it perfect for dinner parties. The filter is integrated into the silicone lid, meaning you just pour and serve. It is made of high-quality heat-proof glass.

Pros:
  • Stunning wine-bottle aesthetic
  • High-quality glass (no odors)
  • Fits in fridge door shelves
Cons:
  • Glass is fragile (handle with care)

Best for Flash Chill
Takeya Flash Chill Maker

2. Takeya Flash Chill Iced Tea Maker

If you prefer Flash Chilling (brewing hot then shocking with ice), the Takeya is the tool of choice. It is made of BPA-free plastic that can withstand boiling water instantly. It seals airtight so you can store it on its side (leakproof).

Pros:
  • Indestructible BPA-free plastic
  • Leakproof (store horizontally)
  • Can handle boiling water safely

  • Plastic can stain over time
