Aquach is a very stylish carafe-style brewer with an immersion filter. The filter can be lifted out with a little handle, and the stopper is a good fit. All looks good, except that the ultra-fine, lasered filter isn’t the best for producing a high-quality brew. However, the brew is good enough to drink, and the glass carafe and stainless steel filter can easily be used for additional hot beverage brewing.
The Toddy uses a freestyle brewing technique with a separate brew vessel. You can adjust the brew ratio as desired. The quality of the brew is excellent all round, as is the design of the product. The most attractive feature of the Toddy is its carafe, which stands out in much the same way as the Aquach does. It can also be used for cold brewing tea; two sample filter bags come with the package.

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.
Like a good wine, the first thing you want to note about a cold brew coffee is the bouquet. Our three coffee appreciators found that the Toddy created a rich and complex bouquet. Hearty and bright notes complemented sharp and deep ones. The sweeter notes also tended to be more floral.
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.
The Toddy Cold Brew System recommends a 1:2 or a 1:3 dilution. We chose a 1:2 ratio (one part coffee to two parts water) based on a sampling of the initial brew strength.
The Toddy has so far produced the most complex flavor balance of any device we’ve tested. The overall flavor was full-bodied and well-rounded. Roasted, nutty, and chocolate flavors were strong, with a somewhat sweetish aftertaste. There was no single overpowering flavor. Our tasters also picked up a very slight bitterness and sourness.
The Toddy brew quality was excellent all around with perhaps the most complex flavor balance of any device tested.
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.
While the Toddy Cold Brew System scored low in terms of the filter’s practicality and ease of use, the brew nevertheless had minimal sediment. The Toddy filter has proven one of the best we’ve seen in our testing program. Our initial test used the reusable felt filter which plugs into the bottom of the brew vessel. You can also use a paper brew bag or even double filtration if you wish.

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.
- Box WDH: 7.5 x 7.5 x 11.8 inches
- Brew vessel with detachable handle
- Decanter with suction lid
- Silicone lid
- 2 felt reusable filters
- 3 paper brew bags
- Silicone stopper
- Product manual
The Toddy Cold Brew System is not only well-boxed, but also ecologically packaged with no unnecessary plastics. The decanter flask sits neatly in the brew vessel and a flip lid with a hole secures the flask in place.
The latest Toddy Brew System includes three sample paper brew bags. These can be used as alternatives to the felt filter, for extra filtration, or for tea brewing. The product manual breaks down how to do each.
- Heightwith 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.
- Heightwith Stopper Lid:8.7
- Base Diameter:5.1
- Weight:1.4 oz (40 g)
- Material:borosilicate glass
The elegant decanter is quite eye-catching. The ringed neck is easy to grip and pour from, but with a full-brew weight of around 3.3 lbs (1.5 kg), you should use both hands. A key design feature is its height — it measures just as tall as the brew vessel, meaning it can fit the same space in your fridge.
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:3.5 in (90 mm)
- Material:low-density polyethylene (LDPE)
- Additional Features:N/A
The stopper is another excellent design feature of the Toddy. It sits slightly above the rim, thus protecting the rim from above. The stopper also has a clever suction design and the fit is perfectly secure and airtight.
- 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.
- Diameter:2.7 in (70 mm)
- Material:felt filter x 2
- Additional Features:3 paper brew bags
There are two types of filters you can use. Both are a healthy and environmental choice. The felt filter can be used up to 10 times. Newer models now include three unbleached paper filter bags. You can use a bag in lieu of a felt plug or in addition to it. The bag filter is perfect for finely ground coffee and for brewing tea. You can easily buy filter pads, Toddy brand filter bags, or generic replacements online.
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.
The Toddy is made from safe, durable, high-quality materials. We particularly liked the quality of the decanter, and the design of the decanter stopper is excellent. The silicone lid is very practical, but we, like many reviewers, felt that the handle build could be improved. The packaging is very minimal and also environmentally friendly. If anything goes wrong, Toddy offers spare parts on their website.

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 Toddy Cold Brew System’s felt filter demands a bit more precision than most other brewers. You must add water and grounds in a staggered manner and be careful not to stir the contents. Also, it takes some time to properly wet the grounds by gently pushing them down and mixing in.
If you use a paper bag filter for brewing, it’s a lot easier. Just add the grounds and water, and you can stir around the contents all you want. If you try to stir without the paper bag, the felt filter will clog. The process takes a few brews to master.
The lack of measurement markings on the brew vessel is an unfortunate oversight. Therefore, we had to weigh grounds for each brewing. The brewer vessel may also be a bit heavy for some. We found it best to carry with two hands, but removing the detachable handle made it easier to fit the refrigerator.
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.
- Total height when decanting: 15 in (380 mm)
Decanting is simple enough. You hold the brew vessel by the handle, pull the stopper, and slip it onto the decanter. The liquid won’t immediately come out, so it’s unlikely to make a mess.
We found, however, that the lively stream can slow to a steady drip. The felt plug filter was temperamental. We actually had to remove the contents of the brew vessel, clean the filter, and then resume. Decanting can thus take 20 to 40 minutes.
Alternatively, you can use a paper bag filter. This works out better and decanting takes 20 minutes or less.
The filter pad, despite its drawbacks, produced the best filtration results. It may also help remove coffee oils, especially if you use an additional paper brew bag. The biggest disadvantage is that you’ll need to continue buying replacement filters and/or bags.
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.
- Storage diameter: 8.6 in (220 mm)
- Storage height: 11 in (280 mm)
The Toddy Cold Brew System has minimal components, so storage is straightforward. The brew vessel is easy to clean and all parts can go into a dishwasher, but hand washing is recommended for a longer lifespan.
The decanter neck is wide enough for all but the largest of hands to reach in and clean. It fits comfortably into the brew vessel for storage. Since the silicone lid is flexible, it too slips in nicely.
The felt filter, however, must be placed in a plastic bag while wet and then put into the refrigerator, which is a little inconvenient. You can easily keep the silicone stopper in the brew vessel when not in use, or place it into the empty decanter.
