If you’re someone who swears by your morning brew, there are few things more important than a reusable cup that won’t let you down. And while they’re a better choice for the environment than paper cups, not all reusable cups are capable of holding their heat over long periods of time.
Here’s how we assess the quality of reusable coffee cups from brands like Kathmandu, KeepCup, Bodum and more.
How we choose what we test
We select products from popular brands that are either available in prominent online and traditional retailers, or ones that have strong brand recognition that you’re likely to seek out.
How we test reusable coffee cups
Performance
We measure how long it takes for boiling water to cool in each cup. First, we drill a hole in each lid that’s 0.1mm larger than the thermocouple we use to measure temperature. Then we fill each cup with one standard coffee serve of boiling water, attach the lid, then insert the thermocouple with the tip as close as possible to the centre of the cup.
The thermocouples are attached to a logger that records the temperature every 60 seconds, while the surrounding ambient air temperature is maintained at approximately 24°C. We then wait for the water to drop to a temperature of 50°C. We analyse this data to determine which cups take the longest to cool down. Cups that hold their heat for longer earn higher scores.
When I first walked through the doors at CHOICE, my job was to write about tech for CHOICE Computer magazine. Since then, I've covered everything from home entertainment to personal safety devices, tech for your car and even mattresses. If you want to find the best combination of a bed, 4K TV, soundbar, GPS unit and food delivery app, I'm your guy.
The one thing I've noticed across all the product tests I've organised it's that nothing is simple.
Mattresses can be just as complicated as computers, and manufacturers as well as salespeople don't make things easy. They either use complex jargon that you just want to ignore, or they
oversimplify things to the point where you don't know what you're paying for.
My goal isn't just to help you find the best TV, mattress or soundbar, I also want to cut
through the nonsense and help you fully understand the products you're considering. That way, you
can make an educated, informed decision when it's time to buy without falling prey to a sly
salesperson.
Plus, when you understand the product, you know how to set it up in a way that best suits your
home and can look after it. Nothing is plug and play anymore, and if a complicated smartphone or
Bluetooth speaker feels less intimidating after you've read my content, then I know I've done my
job.
Outside of work I'm very into gaming, I love
watching retro classics at the cinema, I enjoy getting up early to spend hours smoking a tasty cut of
meat and I'm deeply into home hi-fi. Any music genre from laidback jazz to the loudest, screamiest,
most brutal heavy metal ticks all my boxes. I also had a stint as a live music photographer for a number of years.
