I go through a 12 oz bag of coffee every 2 weeks, so I buy pre ground coffee. I bounce between HyVee brand Donut Shop, French Quarter Medium Roast, Verona Street Breakfast Blend, Medaglia D Oro, and whatever my lady friend brings me from Mexico.
I have a 14 cup Cuisinart drip machine.
I do use my single maker, stove top pot, or my expresso press at times.
