Most Bella coffee maker models use ground coffee, as of 2015. Some models, such as the DualBrew Single Serve Coffee Maker, accept single-use K-cups. The Bella Espresso Maker uses ground espresso beans.
Users can buy ground coffee, coffee beans or K-cups from many major coffee brands, including Starbucks, Dunkin' Donuts and Folgers. Bella Housewares does not sell ground coffee or endorse any particular brand.
Bella coffee makers use different amounts of ground coffee, depending on the desired drink. The Bella One Scoop One Cup Coffee Maker has a small filter and brewing basket designed to brew a single cup at a time. By comparison, the Bella Linea Collection 12 Cup Programmable Coffee Maker has a larger compartment for ground coffee, and it can brew up to 12 cups at once.
