Coffee I make with my Nespresso machine has started to taste increasingly bitter. Why?

There are a few possible reasons why your Nespresso coffee tastes bitter:

• If spent pods are left in the brewing chamber, coffee grinds may accumulate around them. These spent grounds could blend in with subsequent pods, giving your coffee a burnt or bitter flavor.

• A specific level of extraction is intended for Nespresso capsules. The coffee might burn if the extraction is too high, giving it a bitter flavor. Adhere to the suggested extraction size listed on the coffee sleeve to guarantee the best possible extraction.

• Over time, buildups may accumulate in the machine's brewing chamber, spout, and washer plate. When this accumulation and moisture are present, bacteria may grow. These buildups eventually find their way into your coffee, which results in a bitter flavor. Maintaining and cleaning your Nespresso machine on a regular basis can help avoid this problem.
