Ice-Free Ice Drip.
CoolDrip recreates the smooth clarity of traditional ice-drip coffee without the messy ice tower — using a precise, modern brewing system made for cleaner, easier cold coffee at home.
Ice-drip clarity, without the ice tower ritual.
Cold drip is prized for a brighter, cleaner cup because water moves through the coffee bed one drop at a time. The problem is the old ritual around it: fragile glass, melting ice, and hours of fiddly setup.
CoolDrip keeps the part that matters: slow, layered extraction, then replaces the ice tower with a controlled brewing system made for everyday counters.
Drop-by-drop extraction for clean aromatics.
IceFree™ cooling for zero meltwater dilution.
A compact wet path that rinses in about a minute.
The old tower
The CoolDrip approach
Keep the flavor logic. Remove the fragile setup.
Cold brew jar
Easy, but muted
Long steeping makes a smooth cup, but the aromatics often flatten overnight.
Glass drip tower
Clear, but fragile
Traditional ice-drip is beautiful and precise, but the setup is tall, messy, and ice-dependent.
CoolDrip
Clear, and easier
Drop-by-drop extraction stays, while cooling and drip stability move into a compact system.
An instrument, not an appliance.
SUS 316 stainless, high-borosilicate glass and platinum-cured silicone — sized for one perfect cup, and for the counter it lives on.
How CoolDrip Works
IceFree™ Cooling Technology

Ice dilution
60 s
Teardown & rinse
A thermoelectric (TEC) module replaces ice entirely. Water passes through a hydrophilic cold plate that flash-chills each drop to brew temperature in under a second — delivering clean, undiluted cold drip every time.
01
Peltier cold plate
A solid-state thermoelectric module flash-chills each drop to 2–4 °C — no compressor, no ice.
02
Mariotte constant pressure
The reservoir holds a fixed head pressure, so the drip rate you set is the drip rate you get.
03
Single straight wet path
Every part touching water or coffee disassembles in about 60 seconds, without tools.
04
PID temperature control
Closed-loop control holds brew temperature steady across kitchen conditions.
05
24 V SELV safety
Safety extra-low voltage with triple protection and an IPX4 wet side.
Simple as 1-2-3-4
01
Grind & fill
Add medium-coarse grounds to the filter, then fill the reservoir with room-temperature water.
02
Set the drip
Turn the dial to your preferred rate — anywhere from 0.8 to 2.0 drops per second.
03
Walk away
IceFree™ cooling holds every drop at 2–4 °C automatically. No ice to refill, nothing to watch.
04
Pour & enjoy
Lift the carafe and taste clean, layered cold drip — the way Kyoto intended.
Daily use, at a glance.

This is exactly why Kickstarter matters
CoolDrip is not in mass production yet. The product design is complete, and the technical approach has been defined. The campaign exists to fund the expensive next step: tooling, engineering samples, testing, certification work, and production preparation.
The awards recognize the design direction. The engineering plan explains how the ice-free drip system will be built. The next stage turns that finished plan into manufacturable hardware.

Frequently Asked Questions
Not yet. CoolDrip is a completed product design with a defined engineering path. Kickstarter funding is what moves it into tooling, engineering samples, testing, certification work, and production preparation.
CoolDrip uses a thermoelectric (Peltier) module — a solid-state device that pumps heat electrically. Water passes over a hydrophilic cold plate that chills each drop to 2–4 °C, with zero ice and zero dilution.
A full single-cup brew takes 2–4 hours depending on your drip-rate setting. The adjustable valve lets you dial in anywhere from 0.8 to 2.0 drops per second.
Not at all. CoolDrip has a single straight wet path that disassembles without tools. A full teardown and rinse takes about 60 seconds — faster than grinding your beans.
Yes. CoolDrip runs on 24 V SELV (safety extra-low voltage) with triple protection — overcurrent, overheat, and humidity — and an IPX4-rated wet side.
Medium-coarse grounds, similar to a French press grind. We recommend single-origin light-to-medium roasts for the cleanest, most aromatic cup.
Cold brew steeps grounds for 12–24 hours and tends toward heavier, flatter flavors. Cold drip passes water through the bed drop by drop, extracting a cleaner, more aromatic cup with less bitterness — and CoolDrip does it without ice.
