The Hario Mizudashi is a product by one of Japan’s leading coffeeware manufacturers, Hario. The tall, slender glass carafe is quite attractive and will fit even a small refrigerator door. The delicate glass makes cleaning cumbersome, but the filter has a removable base.
Despite its attractive looks, the short filter of the Hario Mizudashi and its brew ratio (1:14) does not produce a worthwhile cold brew and the vessel itself is not airtight. For these reasons, we do not recommend the Hario.
The Takeya, on the other hand, is a very convenient design that is also well executed. The unique filter, with a 1:9 ratio, screws into the lid and you can shake the vessel during brewing and even lay it on its side. The Takeya is lightweight and made in the USA from highly durable Tritan plastic. Its drawback is the number of parts it separates into for cleaning.

After 18 hours of brewing, the bouquet produced by the Hario Mizudashi can best be described as medium strength. The brew brought out a dominant nuttiness, but with underlying bitter and resinous notes. Sweet notes were very understated.
The Takeya cold brew coffee maker produced a moderately strong bouquet and one of the better ones we’ve sampled. Crisper and sweeter notes were present, but somewhat subdued. Earthy notes, with acidic overtones, tended to be more prominent.
Compared to other cold brew coffee makers we tested, the Hario output tasted like a low-grade coffee. There was no real distinction to it and the texture was not smooth. We detected a mild woodiness indicating an under-extracted brew. With dilution, it tasted somewhat watery and sour with a bitter aftertaste.
We diluted the Takeya concentrate 1:1 with filtered water. While the Takeya had a complex flavor profile, it was more medium-bodied. Deep earthy or chocolatey flavors came through the most with a strong roasted flavor. A tinge of sweetness made for a light aftertaste and overall it was smooth and enjoyable to drink. Adding cream to the water dilution resulted in a more finished taste.
The Hario produced noticeable sediment, but most of it is relatively fine with only a few large granules present. The filter worked well, but at the same time its design may be a compromise for the poor quality of the brew.
With repeated testing, we found that the Takeya has a tendency to produce quite a bit of sediment depending on how you handle it. You have to screw the filter tightly into the lid, and avoid shaking too vigorously. Though you can technically brew with the Takeya on its side, it’s probably best to brew standing up. We allowed the concentrate to settle, decanted into another container, and discarded the sediment left behind.

- Width:5.4 in (138 mm)
- Weight:15.0 oz (425 g)
- Material:heat-resistant glass, polypropylene plastic
The Hario Mizudashi brew decanter is quite attractive in its design and this is a key reason why people choose to buy it. It fits easily into the door of even a small refrigerator and looks good on the table. The handle is fixed to the glass and cannot detach and there are a number of colors to choose from.
- Heightwith Stopper Lid:12.2 in (310 mm)
- Base Diameter:4.3 x 3.7 in oblong (110 x 95 mm)
- Width:5.9 in (150 mm)
- Weight:12.0 oz (340 g)
- Material:BPA-free Tritan plastic
The Takeya has a slightly oblong base which tapers up to a round top. It therefore tends to fit most refrigerator doors. The brew decanter has a screw-on frame with a handle and a screwable lid that also attaches to the filter. The high-quality Tritan plastic looks very clean and is also stain, odor, and shatter resistant. The decanter is made in the USA while the filter is made in China.
Stopper / Lid
- Diameter:3.7 in (95 mm)
- Material:polypropylene plastic
- Additional Features:N/A
While we liked the slender and practical design of the Hario Mizudashi decanter, the lid design is not completely airtight. This we thought to be a fundamental design flaw especially for odor contamination in the refrigerator and excess oxidation while brewing. The lid itself has a snap mechanism so it doesn’t slip off accidentally.
- Diameter:6.3 in with handle (160 mm)
- Material:Tritan plastic
- Additional Features:silicone gasket
We tested the decanter vessel and were happy to find it did not leak. The product is very secure and tight. The lid partially unscrews for pouring, and then further unscrews to remove completely. The container can also hold hot liquids, but you should not fully seal the lid while still hot.
- Length:6.5 in (165 mm)
- Diameter:3.3 in (85 m)
- Material:polypropylene frame, polyester resin
- Additional Features:detachable base
The best thing about the filter is the removable bottom which makes it easy to clean. Additionally, it’s small, stores away easily, and appears to be of high quality. However, the relatively short length of the filter and its lack of porousness created a weak and rather sourish brew.
- Length:0.4 in (265 mm)
- Diameter:2.7 in (70 mm)
- Material:nylon & polypropylene
- Additional Features:detachable extender
A key feature of the Takeya cold coffee brewer seems to be the full-length filter that maximizes contact with grounds. The grounds fill the filter and go part way up into the extender.
It comes in two parts, and the upper extender detaches for easy cleaning, which seems to be its key function. However, we found it a bit cumbersome to attach the extender to the filter. The filter is a porous nylon polyester and allows for a relatively good brew to develop. A filter replacement is also available as a separate purchase.
The Hario Mizudashi is well built. The brew decanter is elegant and the plastic parts fit well. The filter is also easy to clean thanks to its removable end cap. However, the design is flawed in the short length of the filter and the non-airtight lid.
9The Tritan plastic brew decanter is a high-class piece of equipment and the airtight screw top is well-designed. The long filter, however, requires more effort for cleaning. The way the filter assembles is also a little cumbersome. Additionally, the sediment test shows that the filter is not so effective if you’re careless when putting it together or if you shake the vessel too vigorously. While overall of good quality, there are more parts than we’d prefer.

Brewing with the Hario Mizudashi is very straightforward. You don’t immerse the filter into water, but instead gradually pour water over the grounds once the filter is put in place. After pouring, you mix the grounds around a little.
There’s no real need for measuring. The prescribed 80g of coffee more or less reaches the top of the visible portion of the filter. You then add water until it reaches the level of the plastic neck.
The Takeya cold brew coffee maker doesn’t require any gradual wetting of the grounds. Just put 170g of grounds in the filter (it should come to 2 inches from the extender rim) and you’re ready to go.
Then, you screw on the lid and immerse it into the pitcher with 7 cups of cold water. If you prefer metric, that’s roughly 1,680 ml — about an inch from the top of the vessel.
After inserting the filter with the grounds, we shook the container and let it sit for 10 minutes. The brewer was shaken thoroughly once again before going into the refrigerator on its side. We shook the container periodically another four times over the 18 hours of brewing. This device therefore takes a little more attention than other methods, but overall it’s quite straightforward.
A key selling point for this brewer is its airtight seal. This means coffee odors will not contaminate your refrigerator while brewing. There is also less oxidative stress, so you can store your coffee longer.
Decanting is about as effortless as brewing. You simply pop the lid off and remove the filter. You may want to leave the filter at an angle in a glass to catch any remaining concentrate as it drips out.
Decanting the Takeya simply means unscrewing the lid and taking out the attached filter. Next, unscrew the filter from the lid and then screw the air-tight lid back onto the pitcher.In this sense, it’s one of the most convenient immersion brewer designs.
After removing the filter, the manufacturer recommends you place it in a tall glass for 45 min to catch remaining concentrate. You should also clean the lid of any grounds before screwing it back onto the decanter. These tips are only found on the product homepage.
As pointed out, if you fail to attach the filter extender securely, or shake the vessel too vigorously, you may have to decant the contents a second time.
When you need to decant some coffee to drink, partially unscrew the lid to align the gap to the spout. It’s safe to pick up the container by the lid handle because the lid ring remains securely attached.
Cleaning and Storage
One thing the Hario Mizudashi has going for it is the practical filter design. The bottom comes off so it was very easy to clean. The slender brew decanter is too narrow and long for hand cleaning, but you can use a brush. All parts are also dishwasher safe. Once everything’s dry, store it fully assembled. Its height is the main concern when it comes to storage.
In total, the Takeya separates into seven cleanable parts. The online instructions state that all parts, including the filter, are dishwasher safe. We presume, however, that it would be better to not put the rubber gasket for the screwable lid into the dishwasher. For hand washing, it’s very easy to reach inside the brew vessel.
The filter itself is quite long, and was difficult to clean without a bottle brush. Without proper cleaning, over time coffee oils can clog the fine holes and produce a stale smell. For deep cleaning, you should soak in a 50/50 solution of water and white vinegar.
Cleaning was not as straightforward as it seemed like it should be. The handle has a nice silicone sleeve for comfortable gripping. It took a little effort to remove that for cleaning and to replace it again.
Storage is easy enough because all parts screw together and you are unlikely to misplace any parts if you reassemble properly. Replacement filters can also be purchased online.
