We get a ton of questions about how Joulies work in different containers. We have always tried to provide the most accurate and helpful answer, but no matter what it's difficult to articulate because so much depends on your individual coffee ritual. When I saw Adam Lisagor's tribute to his Aeropress it made me think how well my morning ritual would lend itself to a video. Here is honestly one of my favorite ways to use my Coffee Joulies. In this double walled mug, the coffee is ready to drink several minutes sooner and will stay in the perfect temperature range for a few minutes longer, just like the graph we show on the perfection pack page, but with a scaled down x axis. Anyway, here is the video, hope you like it. Also check out Adam's video here: https://vimeo.com/40980282
