PLAIN, unadulterated, COFFEE-flavored coffee with half and half and sweetener, is the only thing I prefer to drink. I dislike flavored coffee and will only drink it if there is nothing else.
But seriously my favorite brand pods are Eight O clock really good coffee flavor without being overpowering or bitter Ive tried their regular and Columbian Peaks both are excellent.
Alterra/colectivo coffee is the way to go. Its a random brand i found online. Brewed in wisconsin. Try it. Many different blends, strengths, acidity levels.
