The Aquach is a nicely designed and good-looking glass carafe brewer. The stainless steel filter has a little handle to lift it out, and it can easily double up as a hot tea brewer. The quality of the cold brew produced is a little less than average since the fine-lasered filter doesn’t work the best.

The OXO, on the other hand, uses a free-style brewing technique so it is able to develop a full-strength cold brew concentrate. Brew guide markings on the brew vessel mean that you don’t have to worry about measuring out your grounds. The OXO proprietary rainshower dripper then evenly distributes the water over the grounds.

The OXO is a dedicated cold brew coffee maker, but if you require something more versatile, the Aquach is not a bad choice, but there are similar types of glass carafe brewers that make a much better brew.

Bouquet

9.0

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.

A cold brew coffee bouquet is always a good measure of the brewer’s performance. In repeated testing, we found the bouquet of the OXO Compact concentrate was quite strong. It tended towards deeper chocolate, earthy, or nutty notes. Sweet notes were less noticeable.

At first, we were surprised by the overall results of the OXO compact. Therefore, we did a second brewing for 14 hours and not 18 hours as per our standard testing procedure. Even so, the OXO Compact failed to bring out sweeter notes. Its ‘rainshower’ drip-and-leave brew method seems to be the key determining factor.

7.0

Drinkability

9.0
Aquach Cold Brew Drinkability

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.

Oxo Compact Cold Brew Drinkability

We diluted the OXO concentrate at a 1:2 ratio with filtered water. The final drink had a smooth texture to it, and was only slightly sour. Chocolate, earthy, and nutty flavors were dominant. The brew tended to lack sweet or fruity flavors that other brewers were better at producing. While quite satisfying, it lacked overall excitement and complexity.

We thought this concentrate to be a good choice for ice cubes, using in deserts, or mixing with things like protein shakes. If you love a strong brew, we highly recommend the OXO Compact. One thing to consider with the OXO is brewing with less grounds to water, or brewing for a shorter time.

8.0

Sediment

9.0
Aquach Cold Brew Sediment

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.

Oxo Compact Cold Sediment

The OXO Compact uses a simple reusable mesh filter. It didn’t clog the brewer and the decanting was quite swift and effortless. The sediment was very fine, but with some noticeable granules. While not the most thorough of filters, it was effective and speedy.

In the Box

Aquach Cold Brew 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.

Oxo Compact Brew In the Box
  • Box WDH: 8.5 x 5.2 x 5.2 inches
  • Decanter with stopper
  • Brew vessel with mesh filter
  • Rainshower and lid
  • Manual

The contents were well packaged and secure with the decanter neatly placed inside the brew vessel. The ‘rainshower’ dripper was on top. All key components are neatly labeled on the side of the box, so you know exactly what you’re getting. Overall, however, we felt that there was too much disposable plastic in the packaging.

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.

The glass decanter has a neat aesthetic design with a simple logo and a measuring dot. It did, however, feel somewhat delicate, so we handled it with care.

Aquach Cold Brew 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.

Oxo Compact Stopper / Lid
  • Diameter:
    2 in (52 mm)
  • Material:
    cork
  • Additional Features:
    silicone seal

The silicone seal completely covers the cork stopper making it non-porous. However, the fit of the cork in the decanter is not so tight. The cork slips off easily so you should grip the decanter firmly with your hand.

  • 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.

    N/A

  • Additional Features:
    red silicone gasket, spring valve

The detachable base of the OXO Compact is basically the filtration unit. The base is tight, yet easy to unscrew, and sports convenient alignment markers. The mesh filter fits snugly into the base.

Our concern here is the care needed in looking after parts — especially the red gasket. The filter seems durable enough, but it’s hard to judge the durability of the metal spring valve. Most cold brew coffee makers have simpler components.

Aquach Build Quality

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.

Oxo Compact Build Quality

The OXO Compact is a very well-built product. It’s stylish, high quality, and all parts are certified safe. There are more parts to deal with compared to other cold coffee brewers. Additionally, only time can tell the longevity of the red gasket and the spring decanting valve. The carafe, while attractive, is somewhat delicate and the stopper is not the best.

Brewing

9.0

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.

Oxo Compact Brewing

Brewing with the OXO Compact was completely effortless. One reason for this is convenient markings. The base is also very secure and leak proof. Simply align the bar markings on its parts and you’re ready to go.

For grounds, you fill the brew vessel up to the bean icon — that equates to around 6 oz (170 g) Then, fill the decanter with 12 fl oz (355 ml) of water (marked by a dot). Next, you simply put the ‘rainmaker’ in place, slowly pour the water around, attach the lid, and allow your coffee to brew.

Decanting

9.0

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.

Oxo Compact Cold Decanting

Decanting the OXO Compact requires you to place the brew vessel over the small decanter. It fitted perfectly without toppling off. As soon as pressure was applied to the spring valve, the concentrate started decanting. 

Decanting took less than 5 minutes, but you can extract a little more if you leave it for longer. The mesh filter worked well, or comparable to a nylon filter. 

One issue was the sensitivity of the decanting valve. We had to be careful not to accidentally touch it while moving the brew vessel because liquid spilled out very easily.

9.0

Cleaning and Storage

8.5

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.

The OXO Compact has more separable parts than most cold coffee makers. The carafe appeared somewhat delicate, but cleaning it was mostly a matter of rinsing or soaking in hot water. You can clean inside using two fingers, but it can also go in a dishwasher for a deep clean. 

The silicone seal is easy enough from the cork stopper for cleaning. The brew vessel is wide, so it was easy to clean. However, you should be careful not to misplace the red gasket on the bottom. 

For storage, the OXO Compact is really well thought out. The carafe sits in the brew vessel. Then, if you rest the lid and carafe stopper at an angle, the ‘rainmaker’ inverts for use as a lid for storage.
