Short answer: Get the Mizudashi Cold Brew Tea Pot (1000 mL, $20.50 at Hario USA) for more tea per batch at a lower price. Hario lists it as dishwasher safe. Get the Cold Brew Tea Wine Bottle (750 mL, $27.50), sold in Japan as the Filter-in Bottle, if you want the wine-bottle look and a silicone stopper.

How we compare: every spec in this article comes from official manufacturer specifications and product pages (starting with Hario USA’s tea pot page and wine bottle page), all listed under Sources below. We don’t run hands-on tests, and if a spec isn’t published, we say so. Last updated: October 2026.

I live in Japan, where a jug of cold-brewed barley or green tea in the fridge is a summer staple. These are Hario’s two best-known cold brew tea vessels.

I haven’t tested these side by side. Everything below comes from the manufacturers’ official product pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

Sizes, capacities and materials are from Hario USA product pages. Hario USA doesn’t publish product weights on these pages, so we don’t list them.

Key differences at a glance

  • Capacity: The Mizudashi tea pot holds 1000 mL, while the wine bottle holds 750 mL.
  • Price: Hario USA lists the tea pot at $20.50 and the wine bottle at $27.50.
  • Cleaning: Hario USA lists the tea pot as hot water and dishwasher safe, and its wine bottle page doesn’t mention dishwasher use.
  • Height: The tea pot is 265 mm tall, while the wine bottle is 300 mm.
  • What stays the same: Both are made in Japan, have a built-in strainer and pour without removing the tea leaves.

The 4 Differences That Matter

1. Volume

1000 mL versus 750 mL. For a family drinking iced tea all day, the pot’s extra 250 mL helps.

2. Fridge fit

The two are almost equally slim (84 mm vs 87 mm wide). The pot is 35 mm shorter, so it fits more door pockets.

3. Cleaning

Hario USA lists the pot as dishwasher safe. A Japanese owner of the wine bottle found its silicone spout grooves fiddly and said tea stains on the strainer were hard to remove.

4. Style

The wine bottle comes in five colors and is designed to go on the dinner table. The pot comes in one color.

What’s the same

Both are Japanese-made heatproof glass vessels that cold-brew loose tea, herbs or fruit in the fridge and pour through a built-in strainer.

Who Should Buy Which?

Choose the Mizudashi Cold Brew Tea Pot if you:

  • Want the most tea per batch
  • Want dishwasher cleaning
  • Want the lower price

Choose the Cold Brew Tea Wine Bottle if you:

  • Want it on the dinner table
  • Want a color choice
  • Like a silicone stopper seal

Cold Brew Tea in Japan

In Japan the wine bottle is the フィルターインボトル (FIB-75, 750 mL), sold at about ¥1,980-2,200 on Hario’s Japanese store. Its 1000 mL Mizudashi tea pot (MD-10) is listed there at ¥1,650. Hario says the bottle was designed so people could enjoy cold-brewed tea with meals, the way they would wine.

A Japanese blogger who used the Filter-in Bottle for two years liked how it fits the fridge door, its wine-bottle look, and a seal good enough that it didn’t spill when knocked over. The downsides were silicone grooves that need a cotton swab to clean, tea stains on the strainer, and a strainer that can drop into the bottle if it isn’t seated properly.
