Thanks to Ninja, I can now enjoy my morning caffeine fix in a heatwave without sipping a scalding cup of coffee. Having previously tested Ninja’s Sip Perfect coffee mug, designed to keep drinks at the perfect drinkable temperature, I had an ingenious idea. If it can keep my coffee hot, surely it can keep it cold.
I had high hopes that Ninja’s new travel mug, launched at the end of 2024, would keep my iced latte at the ideal temperature without it turning lukewarm. So, I grabbed my kitchen thermometer and put it to the test.
The chill factor
I started by making an iced latte and then poured it into the Ninja Sip Perfect, which holds 16oz of fluid. I then measured the temperature of the drink using my ThermoWorks One thermometer, and continued to do so every 30 minutes for a total of three hours. By the end of my experiment, I really needed that latte!
Time (minutes) | Temperature °C | Temperature °F |
On making | 10 | 50 |
30 | 9.5 | 49.1 |
60 | 10.3 | 50.54 |
90 | 10.4 | 50.72 |
120 | 10.6 | 51.08 |
180 | 11 | 51.8 |
240 | 11.8 | 53.24 |
I was impressed with the results. Over the three hours, the temperature rose by only 3.24°F (1.8°C), with the largest increase of 1.42°F (0.8°C) occurring during the final 30 minutes.
And when tasting the iced drink, it was still incredibly chilled, as I was after having my first few sips.
What I love so much about Ninja’s Sip Perfect is that it makes it possible to enjoy an iced coffee on the go. Take it on a car journey, pop it into your rucksack, or, like me, just enjoy it at your desk. What’s more, you can save a dollar or two on takeout coffees. Now, that is refreshing.
