K-cups technically only have enough coffee grounds for a strong 6-ounce brew. If you make more than 6 ounces of coffee, it will result in a watery, weak beverage.

Additionally, there's no way to alter the brewing process to make the final product stronger. That's why you should use two K-cups instead of one for more concentrated coffee.

Doubling the K-Cups effectively doubles the coffee grounds, intensifying the brew's strength. This results in a richer taste and a heightened caffeine content.

To get a richer brew, warm up the Keurig, pop in one coffee pod, and opt for a small four or 6-ounce cup of coffee. Once the Keurig does its job, repeat the process with a new pod.

Experiment with the brew size settings on your Keurig to find the perfect ratio. You may find that two 4-ounce batches are too strong, while a 4- and a 6-ounce batch is just right.

The double pod technique can help ensure each cup is to your exact specifications and is a satisfying size. It also allows you to mix and match K-cup flavors to suit your tastes.
