It's something you probably don't often think about, but this morning may be the time to clean your coffeemaker. Fill the carafe with four parts water and two parts white vinegar and run the mixture through the coffeemaker (minus a filter). When it's finished, let the machine cool. Then run a full pot of cold water through the coffeemaker. A thorough cleaning will remove trace minerals left behind and give you a fresher, tastier cup of java.
