Q: Can I Use Milk in My Keurig Brewer?
A: Don’t do it! Here’s the reason: The Keurig gets the water used to brew to boiling point, which is something you never want to do with milk because it causes it to curdle and creates a thick skin on top. This can create a blockage in your machine and cause it to not work properly, or not at all. Try only running half a cup of water through your Keurig and then half a cup of preheated milk into your cup as an alternative.
