In terms of brew strength and quality, Cafe Du Chateau cold brew coffee maker slightly outperforms Aquach. This is because the Cafe Du Chateau has a more porous filter. However, apart from that, it is not a brewer we recommend. The device is bulky, is unsteady while pouring, and its stopper is not well-designed.
Aquach, on the other hand, has quite an attractive design. The stainless steel insertable neck is a unique feature, as is the easy-to-lift filter. Aquach also doubles up as a hot beverage brewer and it pours really well. If you like the look of Aquach and appreciate its versatility as a stylish breakfast table carafe, it's not a bad choice.

Bouquet
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.
When testing the bouquet, we noted that the steel decanter lip provided the perfect chamber for sampling the coffee’s aroma. The concentrate had an understandably medium-strength bouquet. Notes were not harsh or even roasted. Instead, we detected a light chocolatey note with a sweetish overtone.
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.
The final drink, diluted at a one-to-one ratio, was comparatively weak. That’s not to say that it was unsatisfying. It lacked a complex body, but had a sweet overtone. Without dilution, a roasted and nutty flavor came through, but still, the aftertaste was not so rounded.
If you prefer a weaker brew with a milder taste, the drinkability of the Aquach is not bad at all. The brew ratio would suggest the coffee should be drunk as it is and not diluted. You could brew using the hot blooming method, brew at room temperature and for a longer time, or add flavor enhancers for a more robust drink.
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.
The Aquach, with its super-fine filter, produced little sediment with only fine granules. Although it didn’t measure up to our leading brewer with a bottom tap filter, it was pretty comparable. For an immersion filter, however, this suggested a lack of permeability contributing to a weak brew.

Cafe du Chateau Cold Brew Maker 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.
- Box WDH: 2.1 x 2.1 x 9.6 inches
- Fully assembled unit
- Brew guide & manual leaflet
The Aquach comes in a nice box with key parts labeled on the side.The box is double layered, but we felt the decanter was a little overpackaged with three layers of plastic bubble wrap. The brew guide and manual were inside the decanter, and there were instructions for brewing tea as well as cold brew coffee.
Cafe du Chateau Cold Brew Decanter
- Height With Stopper Lid:9
- Base Diameter:5
- Width:6.5" (16.5 cm)
- 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.
- Height With Stopper Lid:8.5 in (215 mm|)
- Base Diameter:5.5 in (140 mm)
- Width:6.3 in (160 mm)
- Weight:borosilicate glass
- Material:18.5 oz (526 g)
One way in which a cold brew coffee maker can distinguish itself is with a stylish decanter. Aquach does pretty well here. On the side is a measurement scale in milliliters and cups. The base, however, is a little wide, so it may not fit some fridge doors.
The flattish handle is very nice to grip, and the stainless steel lip and stopper are also very pleasing. Although the black silicone seal looks like any others, it’s better quality than we’ve seen on most brewers.
Stopper / Lid
- Diameter:3.9 in (100 mm)
- Material:stainless steel
- 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.
- Diameter:3.1 in (80 mm)
- Material:stainless steel & polyurethane
- Additional Features:silicone seal
The nice thing about this brew decanter is the filter which simply lifts out of the container and its resting base remains as it is. This means there’s little difference in how the stopper fits with or without the filter present. The silicone seal is better quality than what we’ve seen on other brewers.
Filter
- Length:6.7 in (170 mm)
- 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.
- Length:5.9 in (150 hmm)
- Diameter:2.6 in (65 mm)
- Material:fine stainless steel
- Additional Features:lifting handle
The Aquach filter design is quite unique. For one, the filter has a convenient handle. It rests on the stainless steel lip so you can simply lift it up. The filter is smooth with no sharp edges. There are also holes on the bottom of the filter.
What surprised us, however, is how finely it filters. The tiny laser-cut holes are arranged in small rectangles. Our brew tests showed that the high quality filter design was a little too fine to allow a good brew to develop.
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.
The Aquatch Cold Brew Coffee Maker is a really well-designed product. It looks very stylish, the handle is easy to grip, and the filter design is practical. The stainless steel lip and lid work well together and the silicone seals are of good quality too. We also loved that there are no plastic parts except for the knob on the lid. However, as our tests revealed, the fundamental flaw comes from the actual design of the filter rather than the overall quality of the build.

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.
The brew filter takes around 80 g of coarse-ground coffee (14-16 tablespoons). We had to weigh the grounds, but they filled the filter to about an inch from the top. First, however, you should fill the decanter with water to the 600 ml mark — a third of the way up. Then, you insert the filter filled with grounds and continue pouring water until the water rises to the ‘Max’ marking.
We found it best to pour slowly and to leave the filter handle up until the pour is complete. The base of the brew decanter may be a little wide for some refrigerator doors, but it fits well in a standard crisper box or on a roomier shelf.
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.
As with any immersion filter brewer, decanting is as simple as removing the filter. The Aquach brewer has a really comfortable design. The high-grade stainless steel filter has a little flip-up handle so you can pull it out.
Not all immersion filters have holes on the bottom. We found this design quite favorable to brewing and faster at decanting. After decanting, you should rinse any grounds from the filter lip before inserting it again with the stopper.
Cleaning and 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.
The Aquach has a total of six parts. Including two silicone seals. The filter was a little long for hand cleaning, so we recommend a non-abrasive bottle brush. Because the filter is very fine, you’ll periodically need to descale it. This you can do by soaking it in a solution of water and baking soda, vinegar, or citric acid.
For the decanter, we were able to reach inside and hand wash it comfortably. However, all parts except the silicone seals can go in the dishwasher. It stores fully assembled, but check the complete dimensions to make sure you have space for it.
