Key Features

Dual Brewing System

Brew both a single cup using K-Cup® pods and a full 12-cup carafe using ground coffee. Perfect for households with varying coffee needs.

Strong Brew Option

Intensify your coffee's flavor with the Strong Brew button, which slows the brewing process to extract more flavor from your coffee grounds.

Programmable Carafe

Set your carafe to brew automatically at a specific time. Wake up to freshly brewed coffee with the 24-hour programmable clock.

Multi-Stream Technology

Keurig's innovative Multi-Stream extractor punctures the K-Cup® pod in multiple places, saturating the grounds more evenly for optimal flavor extraction.

Energy Saving Mode

Programmable auto-off feature saves energy by automatically turning off the coffee maker after 2 hours of inactivity.

Large Water Reservoir

60 oz removable reservoir allows for multiple brews without constant refilling. Easy-fill design with clear water level indicators.

Brewing Options Explained

Single Serve

Brew 6, 8, 10, or 12 oz cups using K-Cup® pods. Perfect for individual servings and variety.

Carafe Brew

Brew 2-12 cups using ground coffee. Ideal for serving multiple people or for coffee lovers who drink multiple cups.

Strong Brew

Enhanced flavor extraction for bolder coffee. Available for both single serve and carafe brewing.

Hot Water

Dispense hot water for tea, hot chocolate, oatmeal, or instant soups without brewing coffee.
