The difference between the Hario Muzidashi and the Toddy Cold Brew System is the contrast between the lowest and the highest scoring cold brew coffee makers. The Toddy uses a free-style brewing method with an adjustable brew ratio and an airtight brewing vessel. It also comes with a quality glass carafe for decanting.

The Hario, meanwhile, is a tall and slender carafe brewer. It lacks an airtight brewing environment and due to a short filter produces a sour, low quality brew. At the end of the day, it is not a cold brew coffee maker that we recommend people buy.

Bouquet

10

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.

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.

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.

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.

8.0

Sediment

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.

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.

  • 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.

  • 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.

Decanter

  • 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.

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.

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:
    3.5 in (90 mm)
  • Material:
    low-density polyethylene (LDPE)

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.

    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.

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 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.

Toddy-Cold-Brew-Build Quality

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.

 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.

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.

Decanting

7.5

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.  

  • 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

9.0

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.

Toddy Cold Brew Coffee Maker Cleaning and Storage
  • 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.
