Hario Mizudashi vs County Line Kitchen Side-by-Side Comparison



Our Verdict
- Brew Quality (50%)6.5/10
- Design (15%)7.2/10
- Ease of Use (35%)9.7/10
- Brew Quality (50%)7.8/10
- Design (15%)9.6/10
- Ease of Use (35%)9.2/10
The Hario Mizudashi and County Line Kitchen cold coffee brewers are both a good fit for any refrigerator door. However, the Hario is not a brewer we recommend. Despite its attractive and slender appearance, it fails to produce a worthwhile cold brew coffee. The reasons being the filter is too short, the carafe not airtight, and the brew ratio unfavorable.
County Line Kitchen mason jar cold coffee makers are our best recommended small-sized brewers to fit in a refrigerator door or on a shelf. The brew quality is comparable to our top picks for an immersion filter brewer.
County Line Kitchen brewers come in small 1-quart and larger 2-quart sizes. The filter is made of a stainless steel mesh and the plastic screw-on lid has a flip cap for pouring. Once the filter is removed, you can even store the jar on its side. You also have the choice of a plastic lid with or without a handle, or a standard mason jar aluminum lid.

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 County Line Kitchen mason jar brewer produced, at a best, a medium-strength bouquet. We detected a slight nuttiness as well as more subtle sweet notes. The results were not as good as we had hoped for, but promising nonetheless.
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.

We diluted the concentrate with one part coffee to one part filtered water. It had a dominant roasted flavor, but with a slight sweet aftertaste. The drink lacked nutty and fruity flavors that our top brewers were more successful at producing. Although smooth to drink, it lacked body and was not as satisfying as a cold brew can be.
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.

We brewed according to the County Line Kitchen manual’s instructions. This means we did not shake the vessel before putting it in the refrigerator. After allowing the brew to settle and then decanting, we were surprised to see a relatively significant amount of sediment.
The filter is a rough mesh rather than a laser-cut stainless steel filter as seen in other types of brewers. Although this brewer did better than average in producing a sweeter brew, we suggest additional decanting to remove excess sediment. Either that, or run the coffee through a paper filter.

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:7.7
- Base Diameter:3.5
- Width:6.3" (16.0 cm)
- Weight:17.0 oz (482 g)
- Material:glass
The brew decanter is just as robust as any mason jar. The inner lid has a silicone gasket for a perfect seal. A handy notch lets you easily pluck the gasket out for cleaning. When sealed, even if you shake the jar around, no liquid spills and the flip cap stays secure too.
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 in incl.handle (150 mm)
- Material:polypropylene plastic
- Additional Features:silicone gasket
The lid of the County Line consists of three parts. The handle is molded onto the crew-top lid. The handle is easy to grip with an inner thumb groove. To pour the liquid, you simply clip the flip-lid open which also detaches for easy cleaning. Inside the lid is also a gasket for airtight sealing. Although the handle is convenient, you can also opt for a simple screw top without a handle for a more compact option.
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:5.5 in (140 mm)
- Diameter:3.2 in (82 mm)
- Material:stainless steel
- Additional Features:silicone seal
Compared to other stainless steel filters we’ve examined, the County Line Kitchen’s looks and feels heavier. It matches the sturdy solidity of the mason jar and adds to its old-fashioned country feel. Although a fair bit of sediment is produced, our tests revealed that the brew produced is relatively good quality.
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.

It’s difficult not to like the design of the County Line Kitchen cold brew coffee maker. If you like the solid practicality of a mason jar, it fits the bill. The part count is minimal and all components fit well. We also appreciate the option of buying a lid with or without a handle.

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.



Brewing follows six easy steps. Simply load the filter with coffee grounds — one cup per quart (reaching about one inch from the top) — and place the filter in the jar. Then, you slowly add water until the grounds are completely covered and the water level nears the top of the filter.
Allow to stand for a few minutes while the water makes its way through the grounds. Top up with water as needed, screw on the lid, and place in the fridge to brew. We found this process completely effortless with no need for weighing or measuring.
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 the screwable cap may require a little force to remove depending on how tightly you put it on. The filter, though, is easy to grip and remove without any grounds dropping into the vessel. Like similar long-funnel filters, you can always place it in a cup to catch the last few drops. It’s best to rinse the lid of any grounds before replacing and putting the finished brew in your fridge. Because of the amount of sediment produced, we recommend recanting for a second time once the brew has been allowed to settle.
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.
For deep cleaning, you need to remove the flip cap and the lid’s inner gasket. The silicone ring seal for the filter simply slides off. The filter rinses out easily and you can use a gentle bottle brush if you wish. We found the small 1-quart jar a little narrow for hand cleaning, so we used a bottle brush there too.
All parts are dishwasher friendly, but it’s probably better to just rinse off the silicone filter seal and lid gasket. You’ll periodically need to soak the filter in a mixture of water and baking soda, vinegar, or citric acid to unclog coffee oils and remove odors.
After brewing, you will need a small space to store the filter. You should place it upside down so the silicone seal stays safe. When you are not using the jar, everything conveniently stores as a single unit.
