Brief
Define a problem from daily life and design a product that brings a clever solution to it. The product should be ergonomic, feasible and made from plastic material.
Istanbul Metals and Minerals Association calls for designers to craft creative and meaningful products that are evaluated by their members, who are pioneer business owners and prominent industrial designers.
Problem
Kefir is a centuries-old fermented dairy beverage celebrated for its probiotic properties. To create it at home, kefir grains – a mix of bacteria and yeast cultures – are introduced to milk. After 24 hours of fermentation, the kefir grains are gently separated from the liquid using a sieve, and stored in the fridge with a bit of milk for future use.
hygiene
Grains are prone to contamination. All equipment should be sanitized carefully before use.
fragility
Grains shouldn't touch a metal material to be safe, and they get damaged while transferred through jars and sieves.
impracticality
A minimum of 3 jars, 2 sieves and 2 wooden spoons are needed to prepare and store the kefir drink.
Say goodbye to the hassle of constantly transferring your precious kefir grains from strainer to jar.
​

Turn grain jar upside down
Put it on tall jar and twist-lock
Why air-removal is important?
What happens when the grains grow over time?
If the straining has stopped, gently tilt Kefirexx to the left to allow the grains to gather in the lower-tier
This will reopen the holes and straining process contunies
An additional tier has been added to the strainer section to prevent potential blockage of the holes during straining
air-tight
When fermenting kefir, air ventilation is important as it facilitates the release of alcohol during fermentation.
​
Kefirexx provides clean and secure ventilation through its ventilation pipette and spring-loaded ventilation cap system.
Fermenting single-serve kefir
The ventilation cap opens when the pipette is attached and closes when it's removed, preventing the risk of leaving it open while storing grains.
Strainer hole diameter: 2.5 mm.
Small enough to prevent grains from passing through, wide enough to strain quickly
The grain container, with its 250 ml capacity, can be used to ferment a daily glass of kefir on its own
In this case, leaving the transparent lid slightly ajar ensures ventilation
