High Altitude ensures your brewer works properly at higher altitudes (5,000 feet). NOTE: In High Altitude mode the temperature is not adjustable. If you attempt to adjust the temperature, the mountain icon will flash indicating that you are in high altitude mode.
Pre-puncture the portion packs or k-cups
Ever notice that your bag of chips from the store looks ready to pop? That’s because as vaccuum sealed items go up in elevation the air pressure and density inside the item stays the same, while the density and pressure outside the product decreases. This results in a build in pressure within the item such as the bag of chips or the k-cups.
What does all this mean to your Keurig?
The excess pressure could be too much when it is initially put into the Keurig machine and can result in damage after repeated use. So it is best practice to pre-puncture your k-cups prior to use.
Keurig recommends putting the k-cup into the k-cup chamber and pushing down slowly so that the k-cup is punctured by the exit needle. You could also, alternately poke the top with a pin or knife.
