The Aquach is a glass and stainless steel cold brew coffee maker with a unique lid design. It has an insertable stainless steel neck, and the filter lifts out with a neat little handle.
The stopper fits the same whether the filter is inserted or not. The only drawback is its fine lasered filter which doesn’t allow for sufficient cross flow so the brew quality is a little weak.
The Takeya, on the other hand, is about brewing quantity in the most practical way. Its uniqueness is how the filter completely seals by screwing into the lid. This way you can shake the brewer, and brew either standing in the refrigerator door or resting on a shelf.
If you’re looking for a good-strength cold brew coffee, Takeya ranks as one of our better brewers. The Aquach may suit you for its stylish design and versatility as an additional hot beverage brewer.

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.
The Takeya cold brew coffee maker produced a moderately strong bouquet and one of the better ones we’ve sampled. Crisper and sweeter notes were present, but somewhat subdued. Earthy notes, with acidic overtones, tended to be more prominent.
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.
We diluted the Takeya concentrate 1:1 with filtered water. While the Takeya had a complex flavor profile, it was more medium-bodied. Deep earthy or chocolatey flavors came through the most with a strong roasted flavor. A tinge of sweetness made for a light aftertaste and overall it was smooth and enjoyable to drink. Adding cream to the water dilution resulted in a more finished taste.
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.
With repeated testing, we found that the Takeya has a tendency to produce quite a bit of sediment depending on how you handle it. You have to screw the filter tightly into the lid, and avoid shaking too vigorously. Though you can technically brew with the Takeya on its side, it’s probably best to brew standing up. We allowed the concentrate to settle, decanted into another container, and discarded the sediment left behind.

In the Box
- 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.
- Assembled brew decanter
- Inlay leaflet
- User guide
The Takeya Cold Brew Coffee Maker comes fully assembled. Both the inlay leaflet and the user guide are placed in the brew decanter. The User Guide has a product description, brewing instructions, five suggested drink recipes, and a 1-Year Limited Warranty notification.

- 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.
- Heightwith Stopper Lid:12.2 in (310 mm)
- Base Diameter:4.3 x 3.7 in oblong (110 x 95 mm)
- Width:5.9 in (150 mm)
- Weight:12.0 oz (340 g)
- Material:BPA-free Tritan plastic
The Takeya has a slightly oblong base which tapers up to a round top. It therefore tends to fit most refrigerator doors. The brew decanter has a screw-on frame with a handle and a screwable lid that also attaches to the filter. The high-quality Tritan plastic looks very clean and is also stain, odor, and shatter resistant. The decanter is made in the USA while the filter is made in China.
Stopper / Lid
- 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.
- Diameter:6.3 in with handle (160 mm)
- Material:Tritan plastic
- Additional Features:silicone gasket
We tested the decanter vessel and were happy to find it did not leak. The product is very secure and tight. The lid partially unscrews for pouring, and then further unscrews to remove completely. The container can also hold hot liquids, but you should not fully seal the lid while still hot.
- 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.
- Length:0.4 in (265 mm)
- Diameter:2.7 in (70 mm)
- Material:nylon & polypropylene
- Additional Features:detachable extender
A key feature of the Takeya cold coffee brewer seems to be the full-length filter that maximizes contact with grounds. The grounds fill the filter and go part way up into the extender.
It comes in two parts, and the upper extender detaches for easy cleaning, which seems to be its key function. However, we found it a bit cumbersome to attach the extender to the filter. The filter is a porous nylon polyester and allows for a relatively good brew to develop. A filter replacement is also available as a separate purchase.
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.
9The Tritan plastic brew decanter is a high-class piece of equipment and the airtight screw top is well-designed. The long filter, however, requires more effort for cleaning. The way the filter assembles is also a little cumbersome. Additionally, the sediment test shows that the filter is not so effective if you’re careless when putting it together or if you shake the vessel too vigorously. While overall of good quality, there are more parts than we’d prefer.

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.
The Takeya cold brew coffee maker doesn’t require any gradual wetting of the grounds. Just put 170g of grounds in the filter (it should come to 2 inches from the extender rim) and you’re ready to go.
Then, you screw on the lid and immerse it into the pitcher with 7 cups of cold water. If you prefer metric, that’s roughly 1,680 ml — about an inch from the top of the vessel.
After inserting the filter with the grounds, we shook the container and let it sit for 10 minutes. The brewer was shaken thoroughly once again before going into the refrigerator on its side. We shook the container periodically another four times over the 18 hours of brewing. This device therefore takes a little more attention than other methods, but overall it’s quite straightforward.
A key selling point for this brewer is its airtight seal. This means coffee odors will not contaminate your refrigerator while brewing. There is also less oxidative stress, so you can store your coffee longer.
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.
Decanting the Takeya simply means unscrewing the lid and taking out the attached filter. Next, unscrew the filter from the lid and then screw the air-tight lid back onto the pitcher.In this sense, it’s one of the most convenient immersion brewer designs.
After removing the filter, the manufacturer recommends you place it in a tall glass for 45 min to catch remaining concentrate. You should also clean the lid of any grounds before screwing it back onto the decanter. These tips are only found on the product homepage.
As pointed out, if you fail to attach the filter extender securely, or shake the vessel too vigorously, you may have to decant the contents a second time.
When you need to decant some coffee to drink, partially unscrew the lid to align the gap to the spout. It’s safe to pick up the container by the lid handle because the lid ring remains securely attached.
Cleaning and Storage
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.
In total, the Takeya separates into seven cleanable parts. The online instructions state that all parts, including the filter, are dishwasher safe. We presume, however, that it would be better to not put the rubber gasket for the screwable lid into the dishwasher. For hand washing, it’s very easy to reach inside the brew vessel.
The filter itself is quite long, and was difficult to clean without a bottle brush. Without proper cleaning, over time coffee oils can clog the fine holes and produce a stale smell. For deep cleaning, you should soak in a 50/50 solution of water and white vinegar.
Cleaning was not as straightforward as it seemed like it should be. The handle has a nice silicone sleeve for comfortable gripping. It took a little effort to remove that for cleaning and to replace it again.
Storage is easy enough because all parts screw together and you are unlikely to misplace any parts if you reassemble properly. Replacement filters can also be purchased online.
