Hario Mizudashi: Coffee Amounts, Grind and Brew Time

Key Takeaways

• 1Check the model: MCPN-7 uses 50 g coffee and about 650 ml (22 US fl oz) water; MCPN-14 uses 80 g and about 1,150 ml (38.9 US fl oz) water in Hario's current manuals.
• 2Hario specifies medium-fine grounds and about eight hours in the refrigerator. Wet all the coffee gently, then remove the strainer after steeping.
• 3The 600 ml (20.3 US fl oz) and 1,000 ml (33.8 US fl oz) labels are brewed capacities. Use the manual's separate water-input amount, then taste before diluting.

What Is Mizudashi Cold Brew Pitcher?

The Mizudashi holds ground coffee inside a long, fine-mesh basket while water surrounds it in the glass pitcher. Removing that basket separates most of the grounds from the drink without pouring the whole batch through another brewer.

It is an immersion cold-brew device, not a cold drip tower. There is no valve to adjust. Hario lists a polyester-resin mesh with a polypropylene frame, lid and handle; the filter is not a metal brewing basket.

Mizudashi 600 Ml (20.3 US Fl Oz) vs. 1 Liter (33.8 US Fl Oz): Coffee and Water

These are the amounts in Hario's current MCPN-7-B and MCPN-14-B manuals. Match the model code on your pitcher or packaging, rather than choosing an amount from the appearance of a photograph.

Water input is different from brewed volume. Grounds retain liquid, and the final amount varies. Filling the larger version with just 1,000 ml (33.8 US fl oz) because its name says “1 liter” does not follow the 1,150 ml (38.9 US fl oz) input in the cited manual.

What Is the Mizudashi Coffee-to-Water Ratio?

Use the model's grams and milliliters above first. They correspond to about 13 ml (0.4 US fl oz) water per gram of coffee for MCPN-7 and 14.4 ml (0.5 US fl oz) per gram for MCPN-14. Those are calculations from the manual's approximate water volumes, not weighed gram-to-gram ratios or guarantees of finished strength. A generic 1:8 concentrate recipe is a different starting point.

How to Brew Mizudashi Cold Brew

For the model amounts above:

1. Check the strainer. Its removable bottom must be securely attached. Add the coffee and place the strainer in the pitcher as instructed.
2. Wet gradually. Pour water through the grounds a little at a time, wetting all of them. Follow the manual's fill level around the middle of the handle band.
3. Stir gently. Use a suitable spoon slowly to reach remaining dry pockets. Do not scrape or puncture the mesh, pack the grounds down or shake a full pitcher.
4. Refrigerate for about eight hours. Fit the lid and keep the pitcher upright.
5. Remove the strainer. Let coffee drain without squeezing or pressing the basket, then replace the lid and keep the brewed coffee refrigerated.

The MCPN-7-B and MCPN-14-B manuals below show the filter alignment and full handling instructions. This page compares the devices and explains their instructions.

Which Grind and Coffee Should You Choose?

Start with medium-fine, as these manuals specify. “Cold brew always needs coarse coffee” is too broad for this basket. Grinder labels differ, so record your setting; a very fine powder may leave more sediment or obstruct flow through the mesh.

Hario suggests dark-roasted coffee in its instructions. Treat that as its starting recommendation, not proof that lighter coffee cannot work. Choose coffee whose flavor you enjoy and make one measured change at a time after trying the documented method.

How Does Mizudashi Coffee Taste?

Coffee choice, dose, steeping and what you add to the glass affect the result. Its mesh is convenient to remove, but it does not promise the same filtration as paper.

Taste a small chilled portion before ice or milk. If that portion is pleasant but your finished drink tastes watery, adjust the serving additions first. If you change the brew, keep notes on coffee, grind, time and amounts so you can identify what helped.

Who Should Choose It?

It suits someone who wants a reusable filter and a batch waiting in the refrigerator. The practical decision is whether its pitcher and handle fit upright in your fridge and whether you want to clean a fine mesh basket after each batch.

Choose the smaller model when its usable output better matches your routine. For same-day iced coffee without an overnight steep, Japanese iced coffee uses a different, hot-brewed approach. Choose the preparation time that fits your routine.

Mizudashi Troubleshooting

Cleaning the Mizudashi Strainer

Remove used grounds, detach the strainer base as directed and wash the parts with a soft sponge and mild detergent. Inspect the mesh instead of scrubbing it with an abrasive pad. Reattach the base securely before the next batch.

The current manuals permit dishwasher use subject to the dishwasher's instructions. Keep the handle band attached, and use the current model's care directions for its plastic and mesh parts. Heatproof glass does not make the assembled pitcher a stovetop brewer. Avoid turning an older or unrelated filter-cleaning tip into a universal boiling instruction.

Popular Drinks with Mizudashi Cold Brew Pitcher

Start with the plain chilled coffee. Add ice if desired, or measure a little milk into your glass. Use the cold brew drink guide for serving context; a sweetened drink has different nutrition from the unsweetened pitcher.

Taste the chilled brew on its own first. If it is too strong, add water gradually to one glass, stirring and tasting between additions; you do not need to dilute the whole pitcher 1:1.

After removing the basket, I dilute one measured serving rather than the whole pitcher. I like keeping the rest flexible. One glass might stay black, while another gets milk and needs a different strength.

Keep milk and sweeteners out of the brewing pitcher.

Easy Home Setup for Mizudashi Cold Brew Pitcher

Before starting, clear an upright space in the fridge and check that the lid, strainer and base are present. A scale for coffee and a water measure make the two models' instructions easier to follow than an unspecified scoop.

After steeping, remove the strainer and keep the covered coffee cold. Hario's current manuals advise drinking the refrigerated brew within two to three days. A smaller batch may suit you better than storing a large one for longer.

Mizudashi Caffeine, Calories and Serving Size

Caffeine depends on the coffee, dose and serving. For comparison, 240 g (8.5 oz) of generic brewed black coffee represents about 96 mg caffeine, 2 kcal and 0 g sugar. This is generic brewed-coffee data rather than a Mizudashi-specific value.

Serving assumptions and sources

USDA FoodData Central's historical brewed-coffee record, FDC 171890, lists 40 mg caffeine, 1 kcal and 0 g total sugar per 100 g. Multiplying by 2.4 gives 96 mg caffeine and 2.4 kcal, rounded here to 2 kcal. This reference uses beverage mass, not the pitcher's water input or nominal capacity. Actual cold-brew caffeine varies with coffee, dose, extraction, dilution and serving size; added milk and sugar change nutrition.

Common Questions Before You Brew

Can You Brew Mizudashi at Room Temperature?

Use the refrigerator for Hario's eight-hour method. Keep the pitcher upright while it steeps, then remove the strainer. This keeps the preparation aligned with the maker's documented amounts and storage guidance.

Should You Leave the Filter in After Brewing?

Remove it when the steep is complete, as the manual directs. Store the brewed coffee covered in the refrigerator with the grounds separated.

Is Mizudashi Coffee Concentrate?

Try the chilled brew undiluted first. If it tastes too strong, add water or milk gradually to your serving. The model recipes above do not call for an automatic 1:1 dilution.
