The Hario Mizudashi and the Cafe Du Chateau are two cold brew coffee makers that we do not recommend you buy. The Mizudashi fails to produce a worthy cold brew coffee and the Cafe Du Chateau fails in a number of other ways. 

The issue with the Mizudashi, despite its good looks, is the short filter, poor brew ratio, and non-airtight design which all contribute to a rather weak and sourish brew. The long slender carafe, however, is a nice fit for any size refrigerator door bin. 

The Cafe Du Chateau produces a much better-quality brew, but still, pretty average when compared to other immersion filter brewers we have tested. The Cafe Du Chateau is also rather cumbersome. It's heavy, doesn’t balance well for pouring, and the stopper is a poor fit.

Bouquet

6.0

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.

After 18 hours of brewing, the Cafe du Chateau produced a noticeably weak bouquet despite a reasonable brew ratio of 1:8. The bouquet did, however, have a distinctively earthy note. Overall, there was very little complexity and sweet notes were indiscernible.

Drinkability

Hario Mizudashi Drinkability
Hario Mizudashi Drinkability 1

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.

Cafe Du Chateau Drinkability

Considering the brew ratio, we diluted the concentrate with one part water to one part coffee. The final serving was smooth to drink, but the aftertaste was neither rounded nor satisfying. It had a defined roasted and somewhat earthy flavor, but lacked character. Overall, the Cafe du Chateau produced an average to reasonably good brew, but it didn’t excite.

8.0

Sediment

9.0
Hario Mizudashi 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.

Cafe Du Chateau Sediment

After allowing the concentrate to settle, we decanted the contents of the Cafe du Chateau. The filter, made of laser-cut 304 stainless steel, did a good job overall.  There was not much sediment and it was mostly fine with some powdery grains. All considered, the filter seemed not porous enough to produce a high quality brew.

  • Box WDH: 4.9 x 4.3 x 11.8 in
  • Brew decanter
  • Detachable filter
  • Manual

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.

Cafe Du Chateau In the Box
  • Box: WDH: 7 x 2.1 x 10.6 in
  • Fully assembled unit
  • Use manual and brew guide

The Cafe du Chateau was one of the few cold coffee brewers we bought that came with styrofoam packaging. It’s very secure and comes fully assembled. The user manual and brewing guide come together as a high-quality glossy booklet. Both the box and booklet feature a convenient QR code for the customer support email. They promise hassle free replacement for any damaged product. In terms of first impressions, we were well satisfied.

Decanter

  • 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.

  • Weight:
    29.5 oz (836 g)
  • Material:
    borosilicate glass & stainless steel

The brew decanter has the look and feel of a solid and durable product. However, on closer inspection it’s not without its flaws. For one, we found it a bit on the heavy side even when empty. We filled the decanter with water to test pour it, and it poured rather heavily. It also felt unbalanced and the grip was somewhat slippery. The manual says the glass decanter can detach from the stainless steel sleeve, but it was difficult to do, so we left this for the cleaning stage.

  • 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:
    3.9 in (100 mm)
  • Material:

  • Additional Features:
    silicone seal

The stopper has an airtight when brewing, but is rather loose with the filter attachment removed. Furthermore, the silicone seal is very rubbery, deforms easily, and is overall not the best quality.

 Filter

Filter
Hario Mizudashi Filter
  • Length:

  • 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.

  • Diameter:
    4 in (102 mm)
  • Material:
    laser-cut 304 stainless steel
  • Additional Features:
    silicone seal

The filter is made from laser-cut 304 grade stainless steel and comes with a ‘lifetime warranty’. It appeared well-machined and the edges were not sharp. However, like the decanter lid, the silicone seal around the filter top was not such great quality. The filter, however, did allow for a relatively decent brew to develop and the sediment produced didn’t require additional decanting.

 Build Quality

Build Quality
Hario Mizudashi  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.

Cafe Du Chateau Build Quality

The materials used, except for the silicone seals, are generally good quality, however, the design is not well executed. The brewer is all-round cumbersome to handle, the lid and seals are poorly designed, and it is weighted badly for pouring. Overall, this has been one of our least favorite cold coffee brewers to work with and will probably gather dust on the shelf.

 Brewing

Brewing
Hario Mizudashi 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.

Cafe Du Chateau Brewing

Like its design, brewing with the Cafe du Chateau has its unique points. No measuring is required because you just fill the filter with grounds to about 1 cm (less than ½ inch) below the top. 

Then, you gradually pour water through the grounds but you don’t push the filter completely in. The filter has an upper chamber which makes pouring water very easy. The filter itself is very fine so you must wait for water to seep through. The last 200 ml of water takes a little time to pour.

Once the water is just below the 1-liter mark, you push the filter unit completely in and do the same for the lid. Despite the cumbersome design of the silicone seals, they do a pretty good job. Most air is completely compressed out of the brew decanter. All in all, the brewing method seemed very sound and we looked forward to the brewing results.

Decanting

8.0

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.  

Cafe Du Chateau Decanting

As with all similar immersion brew filters, all we had to do was remove the filter and place it in a glass to catch the remaining liquid. The stopper comes off with the filter attached. To separate the stopper, you’ll need to hold the filter tight, twist and pull forcefully.

Additionally, the decanter lid doesn’t fit so snugly when the filter unit is removed.This means that your fridge may become contaminated with coffee odors and the concentrate may oxidize and spoil faster.

Once the filter and grounds are removed, you should have around 700 ml of cold brew coffee concentrate. The overall volume is 900 ml (30 fl oz) with the difference being taken up by the filter and grounds while brewing.

Cleaning and Storage

7.0

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 Cafe du Chateau filter is easy enough. Use a standard non-abrasive sponge. You can reach to the bottom of the filter and the edges are not sharp. The decanter itself is easy to reach inside.

The user manual states the glass decanter is fully removable from the stainless steel jacket. Even after running under hot water, however, we were unable to remove the decanter. We didn’t want to exert too much force and break the glass, nor injure ourselves, so we didn’t succeed in separating the parts. 

All components except for the silicone seals can go into the dishwasher.

Once dried, the brewer can be stored fully assembled. It looks nice on a counter and should easily fit in a standard cupboard or a shelf space. The filter also stands well on its own for storage when the decanter is in use.
