Keurig Vs Ninja: Which Makes The Strongest Cup Of Coffee?

The last thing a weekday wakeup call needs is a weak cup of coffee. Keurig and Ninja are two popular single-serving coffee machines, but there's debate among coffee connoisseurs about which one produces the strongest cup. Between Keurig and Ninja, those seeking bold flavor and more caffeine per pour will have the best luck with Ninja's slower brew times and multiple brew options.

Each of Ninja's four models offers three to four brew styles and up to nine brew sizes on larger models. Each machine can also accommodate standard ground coffee. Keurig offers more than 20 models of pod machines (although we narrowed it down to the 11 absolute best Keurig coffee machines based on customer reviews). While these models can't natively brew from grounds like a Ninja machine, users can fill reusable k-cups with grounds of their choice.

Keurig's focus on convenience and speed often sacrifices brew strength. The longer coffee is allowed to steep in the hot water, the more flavor can be extracted from the grounds. While some advanced models have multiple strength settings, a baseline Keurig has a single brew setting or one additional "strong" option. Ninja's slower brewing, if only by a few minutes, allows for higher extraction, meaning the water has time to dissolve more of the coffee which in turn makes it into your mug.

Although what people actually mean by a strong cup of coffee is subject to some debate, caffeine and flavor are the primary indicators of a strong brew. Whether you're a staunch Keurig defender or a Ninja convert, there are a few ways to get the strongest pour out of your machine.

While there are endless hacks to get the most out of your coffee pods, experimenting with your coffee-to-water ratio will always get results. While you can't control the amount of grounds in a coffee pod, you can try things like brewing two pods per cup, always selecting the smallest ounce size option for a more concentrated brew, and filling your own reusable pods with freshly ground coffee for a bolder flavor.

If the machine produces a weak cup every time, it may be time for maintenance. Descaling, or removing the mineral buildup inside the machine, can boost brew strength and improve flavor. These minerals come naturally from the water used in the brewing process and can slow efficiency and impact taste over time.
