Cold brew is all the rage these days, in South Africa and across the coffee world. Many people are excited about the chance to drink cold coffee that tastes great, and some even prefer the less acidic profile of cold-brewed coffee. For coffee lovers, brewing your own is definitely a worthwhile undertaking especially in the summer months.

If you're just getting started with cold brew, the top-end cold drip towers and immersion systems can appear expensive and daunting. Fortunately Hario has released this updated coffee maker that is a perfect entry point to making your own cold brew.

At 1,000ml finished capacity, this is Hario’s biggest immersion cold brewer available. The sleek Ka Ku bottle has been designed with flat sides to fit anywhere in your fridge as it extracts. What we love about this update to Hario’s popular range of cold brew makers is that its grounds basket is now much wider, meaning it's easier to load with less mess and more coffee for extraction.
