The Hario Mizudashi and the Primula Burke are both relatively popular and attractive, but regardless, neither is a brewer we would recommend. The sourish brew produced by the Hario is largely due to a poor brew ratio, a non-airtight design, and a nylon filter that is too short.
The Primula produces a weak and insubstantial brew because the filter is too fine thereby inhibiting sufficient cross flow. However, the twist-to-pour lid is very handy, and the inner core of the lid unscrews for easy access to the filter or for stirring the contents.

Bouquet
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 bouquet of the Primula was decidedly on the weaker side. It was light and sweet but our testers did, however, pick up a faint roasted note. This indicated that the brew was probably sub standard.
Drinkability
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.
With a typical one-to-one dilution, the final drink was very light, watery, and somewhat sweet. In fact, even without dilution, it was still watery with little complexity. There was a slightly sour aftertaste, so not so satisfying. Although the brew is drinkable without dilution, it lacks excitement or complexity, which also means that the Primula is uneconomical for the amount of coffee ground used.
With the Primula, we would suggest a longer brewing period or brewing at room temperature. Either that, or using the hot blooming method to get a more substantial and richer brew.
Sediment
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.
Having to filter a large quantity of liquid means cold brewing can be time consuming. Convenience, however, comes at a price. Our repeated testing has found that the permeability of an immersion filter is key to producing a quality brew.
The Primula recorded very little sediment, which at the same time betrayed its fundamental flaw. The filter, as good as it was, lacked the permeability to produce a worthwhile cold brew coffee concentrate. In this case, the cost of a perfectly filtered brew was the quality of the brew itself.

Hario Mizudashi Cold Brew Coffee Pot Decanter
- Height With Stopper Lid:11.5
- Base Diameter:3.7
- Width:5.4" (13.7 cm)
- 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.
- Height With Stopper Lid:7.9
- Base Diameter:4.7
- Width:7.4" (18.8 cm)
- Weight:19.5 oz (553 g)
- Material:borosilicate glass & plastic
The decanter or brew carafe is made of thick borosilicate glass and enclosed in a plastic jacket. The jacket doesn’t detach and also forms a base cushion. While cleaning, we noticed that there is an additional silicone seal on the base of the decanter.
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:4.9 in (125 mm)
- Material:plastic
- Additional Features:open/close function, silicone seal
The lid comes in three parts. The outer section has a silicone seal for an airtight fit. The filter attaches to the bottom and you simply press it into the carafe. With the inner lid removed, you can easily pour in the water and then seal the carafe for brewing. When storing decanted coffee, you can open this lid to stir the contents before pouring. To pour, you turn the lid handle to the open spout position.
Filter
- 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:6.7 in (170 mm)
- Diameter:
- Material:polypropylene and nylon mesh
- Additional Features:detachable base
The filter is solid and well-made. In terms of design for a cold brew coffee maker, the plastic jacket appears to be limiting. It is uncertain how much permeability this kind of filter design will allow for proper brewing. In test brewing, we found the filter design to be fundamentally flawed.
Build Quality
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.
Overall we love the high quality of the materials and the convenient design. The mid-range 1.6 qt capacity is also very convenient, and we like how the brewer is wider rather than taller. The only fault is not so much the build quality, but rather the ill-conceived design of the filter.

Brewing
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 Primula filter takes around 3.5 oz / 100g of coffee grounds, which means about an inch to a half below the filter rim. After securing the filter onto the outer lid, you insert both into the decanter. Next, pour enough water to wet the grounds. After a couple of minutes, you slowly continue pouring water until the rising water hits just below the top of the plastic jacket. That’s about 40 fl.oz (1.2 L) or 6 measuring cups. Finally, screw in the top lid so that the spout is also closed.
The brew decanter can sit in the door of your average 33- or 36-inch refrigerator but may be too big for an apartment-sized refrigerator. Brewing was relatively straightforward except for the lack of markers on the vessel. We also found the full carafe to be a little heavy. It weighed 4 lbs or 1.8 kg, so make sure to grip it firmly and avoid letting children handle it.
Decanting
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.
We found that decanting worked best by simply lifting up the outer lid with the filter attached. Because the base of the filter is not permeable, it’s best to let the filter stand in a dish as quite a bit of extra brew still trickled out.
You can immediately remove the filter from the lid. We found a few granules of coffee had gathered around the edges so it’s best to completely rinse off the lid before putting it back. Once again, make sure the spout is closed to prevent coffee odors building up in your refrigerator.
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.
Cleaning the Primula is effortless all round. It separates into seven parts. The filter parts and the lid can go on the top rack of a dishwasher while the decanter on the lower rack. It’s probably best to just rinse off the silicone seals. While cleaning, we discovered an additional seal at the base of the decanter. The plastic padding on the base gives a comfortable feeling when placing on the table, and peace of mind when storing away. We loved the quality of the decanter, except that it can be heavy for some when full, but the grip and pour is good.
