Hario “Mizudashi” Cold Brew Coffee Maker, 1000ml, Black

Product Overview

The Hario “Mizudashi” Cold Brew Coffee Maker is a streamlined, no-frills solution for brewing smooth, low-acid cold brew coffee at home—without electricity, hot water, or complicated setups. Designed with both efficiency and simplicity in mind, this 1000ml brewer uses the traditional Japanese method of steeping coarse-ground coffee beans in cold water for an extended period, extracting rich flavor while minimizing bitterness. The result is a naturally sweet and mellow concentrate that can be diluted to taste, making it ideal for those who prefer a gentler coffee experience without sacrificing depth.

What sets the Mizudashi apart is its minimalist three-part construction: a filter chamber, main body, and secure lid. This straightforward design makes assembly, use, and cleaning effortless—perfect for daily routines or entertaining guests. Whether you’re new to cold brew or already a seasoned enthusiast, this brewer delivers consistent results with zero guesswork. The transparent glass body offers clear visibility into the extraction process, so you know exactly when your batch is ready.

Benefits & Use Cases

The Hario Mizudashi excels in environments where convenience, consistency, and cleanliness matter most. Its large volume means fewer batches are needed to keep up with daily consumption—whether you’re sipping slowly throughout the day or prepping for weekend gatherings. Because cold brewing requires no heat or electricity, it’s an energy-efficient alternative to traditional methods like French press or pour-over.

Cold brew typically takes between 12 and 24 hours to steep in the refrigerator, depending on desired strength and flavor profile. During this time, the slow extraction draws out oils and sugars while leaving behind harsh acids and tannins, yielding a smoother, sweeter concentrate. Once brewed, the coffee can be stored in the fridge for up to two weeks and easily customized by mixing with water, milk, or ice.

The transparent glass allows you to visually monitor the brewing progress—ensuring you never miss the perfect moment to stop steeping. After brewing, simply remove the filter chamber, discard used grounds, rinse all parts, and reuse immediately. No need for special detergents or soaking; a quick wash with warm soapy water keeps everything fresh and hygienic.

This brewer is especially well-suited for people who value clarity in their coffee routine—no pressure, no complexity, just pure cold brew quality every time. It’s also compact enough to fit in standard refrigerators without taking up excessive space.

Important Notes

While the Mizudashi Cold Brew Coffee Maker delivers excellent results, it does not include a built-in pouring spout or airtight seal. As such, it must be placed securely inside the refrigerator during the entire steeping cycle to maintain proper temperature and prevent contamination. Always ensure the lid is tightly closed to protect against odors and spills.

For best results, use freshly roasted, coarsely ground coffee beans. Finer grinds may clog the filter or lead to over-extraction and unwanted sediment. Avoid exposing the glass to sudden temperature changes—such as placing it directly under running water after being chilled—to prevent cracking.

Cleaning is simple: disassemble all components after each use and rinse thoroughly. For deeper cleaning, wash with warm, soapy water and dry completely before reassembling. Avoid abrasive scrubbers that could scratch the glass surface.
