Hario V60 Fretta: How to Make Japanese Iced Coffee at Home

The Hario V60 Fretta brews Japanese-style iced coffee: hot double-strength pour-over poured directly over ice. The hot coffee cools instantly on contact and the melting ice dilutes it to drinking strength. The result is a bright, clear, aromatic cup that preserves everything a hot pour-over delivers.

Japanese Iced Coffee vs Cold Brew: Two Different Cups

Cold brew steeps coarse grounds in cold water for 12 to 24 hours. It produces a low-acid, smooth, full-bodied concentrate. Japanese-style iced coffee brews hot over ice. The heat extracts the same volatile aromatics as hot brewing. Rapid chilling locks them in before they degrade.

How the Hario V60 Fretta Works

Overhead flat-lay of the Hario V60 Fretta components: glass carafe, V60 cone, diffuser lid, and ice tower laid out on a dark surface

The Fretta is a V60 02 cone paired with a glass ice tower carafe. The V60 cone sits on top of the ice tower. Hot coffee drips through the cone and falls over the ice below, chilling instantly. The diffuser lid distributes the pour evenly over the ice tower, preventing channeling. The narrow tower shape speeds controlled melting.

The V60 cone detaches from the Fretta for use as a standard pour-over dripper on any cup or carafe. The glass carafe includes a lid and serves as a server. The whole setup is compact enough for daily use.

The Ratio

Brew at double strength because half the final volume comes from melted ice. Use a 1:8 coffee-to-water ratio and fill the ice tower to the fill line. A standard Fretta brew: 30g coffee, 240ml hot water, ice to the fill line. The ice accounts for the remaining volume and brings the drink to proper drinking strength.

Grind Size

Grind medium-fine, slightly finer than a standard pour-over. The double-strength ratio needs a slightly finer grind to extract fully at the reduced water volume. Use fresh beans. Light to medium roast performs best for Japanese iced coffee.

How to Brew Hario V60 Fretta Iced Coffee in 6 Steps

Step Instructions
1 Grind. Grind 30g of coffee to medium-fine. Slightly finer than a standard pour-over setting.
2 Load the Fretta. Fill the ice tower to the fill line with ice. Place the V60 cone on top. Insert the diffuser lid. Place a filter in the cone and rinse with hot water to remove paper taste. Discard the rinse water.
3 Add coffee. Add the 30g of ground coffee to the filter. Tap the cone gently to level the bed.
4 Bloom. Heat 240ml of water to 200 degrees. Pour 60ml over the grounds to bloom. Wait 30 seconds.
5 Pour. Pour the remaining 180ml in slow circles over 3 minutes total brew time.
6 Serve. Once all the coffee has dripped through, attach the carafe lid and pour directly into a glass. The iced coffee is ready immediately.

Use fresh medium to light roast beans for the best result. Browse the premium coffee collection for whole bean options suited to pour-over and iced coffee. Blackout ships within 1 to 2 business days of roasting.

Tips and Variations

Use large ice cubes

Smaller ice cubes melt faster and over-dilute the coffee before brewing finishes. Larger cubes give you more control over dilution. If ice melts too fast, use more ice or larger cubes.

Without the Fretta

Japanese iced coffee works with any pour-over dripper. Place your V60 or Chemex over a carafe filled with ice. Brew at a 1:8 ratio with medium-fine grounds. The Fretta adds the diffuser lid and purpose-built ice tower but the method works without it.

Add milk or cream after brewing

Pour directly over more ice with a splash of cold milk or cream. The bold double-strength base holds up well against dairy. The flavored coffee collection has options that work especially well over ice with cream.

Frequently Asked Questions About the Hario V60 Fretta

What is Japanese iced coffee?

Japanese iced coffee is hot pour-over coffee brewed directly over ice at double strength. The ice chills the coffee instantly and melts to dilute it to drinking strength. It preserves acidity and aromatics that cold brew does not extract.

What is the Hario V60 Fretta?

The Hario V60 Fretta is a Japanese iced coffee maker consisting of a V60 02 pour-over cone, a glass ice tower carafe, and a diffuser lid. It is designed specifically for flash-brewing hot coffee over ice.

What coffee ratio should I use with the Fretta?

1:8 coffee to water. For example, 30g coffee to 240ml hot water, with the ice tower filled to the fill line. The melting ice brings the final volume to the correct drinking strength.

What grind size should I use?

Medium-fine. Slightly finer than a standard pour-over. The reduced water volume at double-strength requires a finer grind to extract fully.

Can I use the Fretta cone for regular hot pour-over?

Yes. The V60 02 cone detaches from the Fretta and works as a standard pour-over dripper on any cup or carafe. The Fretta doubles as a regular pour-over setup when you are not brewing iced coffee.
