Preparing Contigo Travel Mug for the -10°F Challenge

Setting up a scientific test requires meticulous preparation. Before subjecting the Contigo travel mug to extreme cold, careful consideration went into selecting the right tools and creating reliable testing conditions.

Selecting the perfect test beverage

Following professional testing protocols, boiling water serves as the ideal test liquid. At 212°F, it provides a consistent starting temperature that allows for precise tracking of heat retention. Moreover, using water instead of coffee eliminates variables like beverage composition that could affect temperature readings.

Temperature measurement tools and methods

To ensure accurate results, the test setup includes:

• A lab-grade digital thermometer with wire thermistor probes for precise temperature readings
• A secondary thermometer to monitor environmental conditions
• An infrared camera to detect potential heat leaks

These tools enable taking quick, accurate measurements without obliterating the lid, maintaining real-world usage conditions. The thermistor probes, being thin temperature-sensitive wires, provide instant readings through minimal lid opening.

Creating controlled testing conditions

According to expert testing methodologies, maintaining stable environmental conditions proves crucial for accurate results. Therefore, the testing environment includes:

First, the Contigo travel mug is preheated with hot water for several minutes before adding the test liquid. This step prevents the cold mug from affecting initial temperatures. Subsequently, the preheated water is emptied and the test liquid is filled at precisely 212°F.

The testing area maintains consistent ambient conditions throughout the experiment. A secondary thermometer continuously tracks temperature and humidity levels. This setup mirrors professional testing environments, where variables remain carefully controlled.

The double-walled vacuum insulation of the Contigo mug creates an airless space between inner and outer walls. This design prevents heat loss through conduction and convection. Yet, most heat typically escapes through the lid, making proper lid alignment essential for optimal performance.

Seal integrity plays a pivotal role in temperature retention, ranking as the second most important factor after insulation thickness. For this reason, special attention is paid to ensuring the Contigo’s screw-on lid remains properly aligned and fully sealed throughout testing.

The controlled environment also accounts for external factors that could impact performance. Even though vacuum-insulated containers typically resist outside temperatures well, extended exposure to extreme cold can affect their thermal retention. This consideration makes the -10°F test particularly challenging yet relevant for real-world winter use.
