Hario Mizudashi Cold Brew Bottle Review: Simple, Low-Waste Overnight Coffee

Quick answer

The Hario Mizudashi Cold Brew Bottle 1L is the cold brew brewer that lives in half the coffee kitchens we know. Constructed from glass and polypropylene, it steeps coffee overnight and cleans in ten seconds. Its slim design fits easily into fridge doors while eliminating the need for single-use paper filters or bottled beverages. It is a straightforward, low-waste choice for anyone ready to make their own cold coffee at home.

What the wider world says

External reviewers praise the Mizudashi for its convenience and performance. Serious Eats named it their top pick, describing it as the easiest and cleanest way to make cold brew at home. Meanwhile, The Kitchn gave it a 9/10 rating, noting that you will never buy bottled cold brew again after using it.

Our take

This bottle hits a practical sweet spot for daily kitchen use. The reusable steel filter eliminates paper bags and ongoing filter waste, while the glass body is dishwasher safe for effortless maintenance. It does come with a couple of minor trade-offs. The steel filter requires a finer grind size to ensure clear coffee, and because the pitcher is glass, you need to pack it carefully inside a crowded fridge door.

Who it's for

This is best for cold brew drinkers tired of buying single-use bottles from the store. It is ideal for anyone who wants an uncomplicated overnight steeping routine with minimal ongoing effort.

Who it isn't for

Skip this if you need a portable or shatterproof container for travel. It is also not ideal if you do not want to adjust your grinder to a finer setting.
