My favorite coffees that you buy the beans or already dround are: Dunkin' Donuts (which I can buy at the grocery store & Costco because we do not have Dunkin' Donuts in San Diego yet), Starbucks Christmas blend and their Pike Place. I was given a Keurig coffee maker for Christmas and have been trying a lot different brands and flavors.
When we travel and I have to make coffee I usually make it with bottled water because we have a water filtering system and some places their water is a lot different than what I am used to.
