I finally found two travel mugs that live up to their hype. A quick trip to Canadian Tire and Walmart and I had four new mugs lined up to compete against the household favourite. I filled them all with hot water straight from the coffee maker.
Starting at 73.8 C, the mugs were tested every 10 minutes. Within the first 10, the plastic mugs – including the eco-green Aladdin mug, the cool "no-spill" Mighty Mug and the old house mug – were down nine degrees or more.
The double-walled stainless steel Bubba and Stanley mugs were still piping hot. After an hour, the Stanley was down to 66.7, the Bubba was 57.8, and the other three averaged 51.
Both the Stanley and the Bubba promise to keep beverages hot for at least six hours and they do. I started again, rinsing the mugs under hot water before refilling them with 83.3 water from the kettle and then sealing the lids. Six hours later, the Stanley was 55 and the Bubba 46.1.
Only the Stanley and the Bubba passed all five leak tests. The others were pretty good. Sadly, that's when the house mug, with its slider spout seal, made its last trip – to the trash.
