10 Best Smart Coffee Maker 2025 in the United States

The Keurig K-Duo Gen 2 is a versatile coffee maker that caters to different coffee preferences, brewing both single K-Cup pods and full carafes using coffee grounds. It features MultiStream Technology to ensure even saturation of coffee grounds, enhancing flavor and aroma, whether hot or iced. The machine allows for multiple brew sizes, between 6 to 12 ounces for single cups and up to a 12-cup carafe, making it suitable for personal use or social settings.

The 72oz reservoir is quite large, reducing the need for frequent refills, and the intuitive front-facing control panel makes it easy to select brewing preferences. Additionally, the programmable auto brew feature for the carafe is convenient for setting up your coffee in advance, and the compact design is a bonus for those with limited counter space. However, the lack of app functionality means you won't be able to control it remotely, which could be a downside for those who prefer smart home integrations.

Maintenance is straightforward with a reusable filter and removable tank, but some users might find the plastic components less durable over time. It provides strong brew and extra hot options, which are great for a richer coffee experience, but its weight is relatively light at just 1 pound, suggesting it may not feel as robust as other models. Suitable for both personal and social use, the Keurig K-Duo Gen 2 offers a good balance of functionality and convenience but could benefit from more advanced smart features.

The Keurig K-Supreme Single Serve K-Cup Pod Coffee Maker stands out in the smart-coffee-maker category with its innovative MultiStream Technology, which enhances the flavor and aroma extraction compared to previous models. It offers versatility in brewing with multiple size options (6, 8, 10, or 12 oz.) and the ability to brew stronger or iced coffee, catering to various taste preferences.

The design includes a 66 oz. dual-position reservoir that can be removed for easy refilling, saving counter space. The machine's capability for back-to-back brewing without waiting for reheating is a convenient feature for those who consume multiple cups. Its travel mug accommodation is practical if you enjoy taking your coffee on the go.

However, the Keurig K-Supreme lacks some smart features typical in the smart-coffee-maker category, such as app connectivity and programmable settings. This might be a limitation for users seeking remote control or scheduling brew times from a mobile device. The absence of a milk frother and digital clock might also be missed by those who appreciate more comprehensive coffee-making features.

In terms of maintenance, it provides a helpful alert to descale after 250 brews, adding convenience in upkeep. Although it's acclaimed in user reviews with a 4.2-star rating, potential buyers should note it's more of a manual operation with button controls rather than automated.

This coffee maker is ideal for those who prioritize a straightforward brewing process and enjoy experimenting with different coffee strengths and sizes. While it doesn't offer the full range of smart connectivity features, it compensates with user-friendly design and efficient brewing performance.
