The Keurig K-cups used in Mr. Coffee's single cup brewing system come in flavors that include caramel vanilla cream, kona and vanilla hazelnut, with over 200 other flavors available as of February 2015. The K-cups come in light, medium and dark roasts. Caffeine levels include decaf, half caff and regular.
Keurig K-cups are manufactured by several different brands, such as Green Mountain, Tully's and Folgers. Each brand produces its own variety of flavors. Flavors offered by Green Mountain include a decaf and non-decaf breakfast blend, chocolate glazed donut, cinnamon roll, French roast and double black diamond extra bold, the brand's darkest coffee. Tully's flavors include its house blend, Italian roast and a French roast. Folgers' flavors include black silk, lively Colombian and vanilla biscotti.
K-cups are compatible with Mr. Coffee Single Cup Brewers. The brewers come in sizes of 8, 10, 24 and 40 ounces. Although originally only coffee came in K-cups, the system expanded to include other single serve drinks, such as tea, hot chocolate and fruit drinks. Sampler packs are available that include multiple K-cup flavors from different brands. Mr. Coffee Single Cup Brewers tend to come in silver or black color schemes, but certain models have different color options available, such as red or white.
