Most cold brew coffee makers we tested out-performed the Hario Mizudashi. The Hario doesn’t work as a cold brew coffee maker due to its non-airtight lid design, short filter, and poor brew ratio. Its tall and slender glass carafe is, however, an eye-catcher.
If you’re happy with an average to mild brew and the convenience of a small brewer for a refrigerator door bin, the Coffee Gator is not a bad choice. Its twist-to-pour lid design is also convenient. Additionally, it comes with a couple of thoughtful extras namely a stainless steel measuring spoon and a silicone funnel for pouring in grounds and water.

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 coffee gator was of a slightly medium strength. We detected a mild roasted note, as well as a definite woodiness. There was a slight hint of caramel. This suggested that the extraction was either average or a little under par.
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.
The Coffee Gator produced a mild to medium strength brew. It had a dominant roasted flavor, but no real complexity. The aftertaste had a very slight sourness with a watery finish. It’s a nice enough brew especially if you prefer a little sweetness added. We don’t recommend diluting it, but the addition of a little milk or mixed as a smoothie or protein drink would work fine. You may want to brew for longer than 18 hours.
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.
After decanting the brew, there was a moderate amount of fine granular sediment remaining. This was typical for the type of brewer and filter, or as good as one could expect. If you prefer, you can decant the brew a second time, but there is no grittiness to the final drink.

- Detachable filter
The Hario Mizudashi comes in a very nice box. On the side are simple instructions highlighting its key features. There is no unnecessary plastic covering, and inside you find the decanter, detachable filter, and a handy instruction manual.
- Box WDH: 7 x 5.1 x 12.2 inches
- Borosilicate glass jug brewer
- Stainless steel measuring spoon
- Silicone funnel
- Instruction and message card
Our first impressions of the Coffee Gator cold brew setup were very positive. The carafe has a solid look and feel, the black and white design is very catchy, and it’s not heavy to lift. The stainless steel spoon is something you won’t get with other brewers, and the silicone funnel for pouring in grounds was very thoughtful.
We liked the personalized message card and instruction card too. The box had a seal saying ‘This product is not dishwasher safe’. The box also says if you register for a Platinum Membership, you get an additional year’s warranty, priority access to new products, discount codes, and coffee masterclass brew videos. They have full social media profiles and you can view their videos on Youtube.

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.

The decanter is of excellent quality and the glass is quite thick, but not heavy. The full capacity is 1.2 liters. The plastic neck handle screws on tightly and the only fault is the handle. It’s a little short and uncomfortable while the grip is not so secure.
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:4.3 in (110 mm)
- Material:BPA-free plastic
- Additional Features:2 white silicone gaskets
We loved the design of the Coffee Gator lid. It’s made of clear see-through plastic with a silicone gasket around the inner rim. It fits very neatly into the hole of the screw-on handle rim. The rim handle has an additional silicone gasket for proper air-tight sealing. If you turn the lid slightly to one side, the spout opens up to pour.
The lid design is very practical, however, it’s practically identical to that of the Coffee Bear. Upon reaching out, we confirmed that there is no relationship between the two coffee brands.
- 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:7.8 in (200 mm)
- Diameter:2.5 in (65 mm)
- Material:White plastic & nylon mesh
- Additional Features:Detachable base
We loved the refreshing white design of the filter, and how it clips securely into the rim. The base of the filter unscrews and comes off for cleaning. Since the brew ratio is only 1:14, and the filter had a fair amount of solid plastic, we wondered how well it would actually brew. The mesh filter seemed porous enough on first inspection.
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.
The overall build quality is really good. The carafe is solid and the lid an excellent design. On the downside, the handle lacks a solid grip and feels uncomfortable. The silicone gaskets seem good quality, and the stainless steel measuring spoon and silicone funnel add excellent value to the product.

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 addition of the silicone funnel and the measuring spoon made brewing practically effortless. The recommended amount of grounds is 75 g or 2.6 oz, however, we put in eight spoons to top off some of the space. One level spoon is 11 g, so the total weight was 88 g or 3.1 oz.
The silicone funnel was also perfect for pouring water around the edges so the flow was more gentle and gradual. If you pour too fast, liquid and grounds will move up the funnel, so be careful when you take the funnel out. You can use a teaspoon to push any grounds around the edges into the filter. The lid also made for a perfect air-tight fit.
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.
Like any immersion filter brew, decanting was effortless. All you need to do is pop off the lid and carefully twist loose the neck ring. We detached the filter immediately and left it to rest in a jar to collect the last few drips. After rinsing the screw-on neck ring, we immediately resealed the carafe to protect the flavor and aroma. We returned the brew to the refrigerator to await our brew score testing.
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.
To clean the filter, you need to rinse out the grounds and then gently clean with a bottle brush and a small amount of liquid soap. We noticed a fair amount of coffee oil that required soap for cleaning. Also, the filter lost its pearly white appeal after the first brew. However, you can see the residue oil to wash off more easily than with a black-colored filter.
The carafe itself also cleans easily. We had no problem getting our hands inside, but larger hands may be a problem. You can put the glass carafe in a dishwasher, but Coffee Gator recommends hand washing.
