I had changed my drinking cup to a GSI Bugaboo aluminum cup, mostly because it had measurements. However, I noticed this summer that I was often drinking tepid to cold tea–not cool, er, hot, er, I mean, not good. I had previously used a QMH Angry Troll pot as my cup, nested inside a Toaks 650 mug pot. The Angry Troll has a lid, is made from a Foster’s can, and might be double-walled? So, today, I made a cup of CUSA tea in the Angry Troll with the lid on, and in the GSI Bugaboo, side by side. I measured temperatures every 5 minutes with an instant kitchen thermometer. It was evident that the QMH pot held the heat better, and now that Toaks has liquid measurements in their pots, I don’t worry about measuring water any more (been eyeballing it and haven’t been too sorry). So, back to the QMH pot for a cup. It’s a little wide in my hand to hold comfortably, and doesn’t have handles, but the thermal performance makes it worth it. If you really want to geek out, I have the temps written down.
Craig’s cups would perform way better!
