What is the XFactor™?

Starline has temperature tested our mugs, tumblers, and bottles for temperature heat retention. We have expressed those results in multiples (X-FactorTM) of the time Starline keeps your beverage in the ideal drinking range when compared to a standard coffee house cup with lid.

Putting Our Drinkware To The Test

The coffee industry has determined the ideal drinking temperature for a cup of coffee to be between 175°F and 145°F. With lab control measures in place, Starline conducted a temperature decay test. Using a standard coffee house paper cup with lid as the bench mark, we conducted a side-by-side temperature tests with the Starline family of drinkware. Temperatures were recorded in minute increments until reaching approximately 120 degrees Fahrenheit. We also testedtraditional cold beverage cups with a heat increasing test.
