Questions & Answers
How do I use the Temperfect Mug?
Just pour your hot coffee or tea into your room-temperature Temperfect and let it work its magic! The Temperfect insulation layer absorbs the excess heat so you can enjoy your beverage within minutes, and then for hours.
Will it fit under my coffee maker?
Our mugs are almost exactly 7" tall (18 cm) with the lid off, and we've heard from our customers that they fit the Keurig 2.0, Hamilton Beach FlexBrew, Ninja Coffee Bar, and the Nespresso Vertuo. They will work with many more, just remember: the magic numbers are 7" and 16 fl oz.
Does it matter what temperature my coffee is at initially?
The Temperfect Mug is designed to work best with your beverage right after brewing because it uses the extra heat as an energy source to keep your drink just right for a long time. We measured an average serving temperature of about 175℉ coming out of coffee makers and for tea and coffee served at shops, so that's the temperature we use for designing our mugs. If your drink is at a somewhat higher or lower temperature the mug will still work fine though.
Is the insulation layer safe?
The insulation layer is completely non-toxic and safe. It is sealed in a stainless steel chamber so it can't come in contact with your beverage.
How long does the insulation layer last?
The insulation layer lasts for the lifetime of the mug; it will never lose its potency.
Can I put the Temperfect Mug in my dishwasher?
The lid for the Temperfect Mug is dishwasher safe, and is easily disassembled for thorough cleaning in the dishwasher or by hand. However, we don't recommend putting the main body of the mug in a dishwasher. It is made of stainless steel, and requires only a rinse after use in most cases. The inner surface of the mug has a smooth finish which will not retain flavors of your last beverage.
Does the Temperfect Mug keep cold drinks cold?
The Temperfect Mug will keep cold drinks cold for hours due to the vacuum insulation layer. You can pre-cool your mug in the refrig or freezer for even better cold-drink performance.
Can you show me temperature measurements?
Sure! Here are actual measurements made on our Javabliss 16 mug compared to a thermos mug (Thermos, Stanley, Contigo, Yeti...) and a regular ceramic mug:
The Temperfect Mug brings the coffee down to a drinkable temperature (60℃ = 140℉) quickly and holds it there. Contrariwise, your coffee gets cold fast in a ceramic mug, and seems to never get to a reasonable temperature in the standard thermos mug.
