The Hario scored well for its build quality, but it fell short on the key fundamentals of the lid and filter design. Overall, the design did not contribute to producing a good quality brew.
The Goodful is a relatively large capacity brewer. It’s therefore quite tall and is best set inside a refrigerator door, however, it’s unlikely to fit a small refrigerator. The materials are hardy and durable, but the lid is clunky, and more detailed information on the device is lacking. The quality and look of the filter are a big plus overall.
The Hario Mizudashi is really easy to use because it requires little effort. Additionally, it is easy to brew without having to measure out the grounds or water. The tall size is a little troublesome when hand washing, but everything is dishwasher safe. Our key issue, however, is with the non-airtight design.
It’s quite easy to brew with the Goodful without measuring—although we measured everything carefully for our testing procedure. We particularly liked the filter design with a little handle to lift it out of the container.
The Hario Mizudashi was an overall poor performer. The brew lacked complexity and had an overall sourish taste. This was largely down to a short filter, a poor brew ratio, and a non-airtight vessel. One way to improve the brew quality would be hot blooming where you pour hot water over the grounds and allow to bloom for 30 to 40 seconds before pouring cold water.
The brew produced by the Goodful was reasonable. We liked the slightly bitter edge to the otherwise mild-roasted flavor. The brew also had a sweetish aftertaste, but with a watery finish. We recommend drinking it straight rather than diluting it too much.
Pros & Cons
- Attractive brew decanter
- Easy-to-clean filter
- Color choice
- Hot or cold brewing
- Removable filter base
- Turn-to-pour lid
- Not airtight
- Odor contamination
- Poor brew quality
- Not a good fit for small refrigerators
- Clunky lid
The Hario Mizudashi and the Goodful are two of the tallest cold brew coffee makers that we have tested. By comparison, the Hario is a slender and elegant glass carafe and stands at 11.5 inches. The Goodful, an all-plastic design, is slightly taller at 11.8 inches.
Although both are designed to brew in the door bin of a refrigerator, there are major differences aside. The Hario is not completely airtight, leaks odors, and the poor brew ratio produces a sourish insubstantial brew.
The Goodful is a much better brewer all round. It has a plastic and nylon filter and the vessel is completely airtight and leak-proof with a twist-to-pour lid. Although the material quality of the Hario is much better, it’s not a brewer we’d recommend due to its fundamentally flawed design and poor performance.
