Why does my CASABREWS CM5418BC-UL coffee taste like vinegar?

If your coffee tastes acidic, like vinegar, it could be due to improper cleaning of mineral deposits. Repeat the instructions on page 5 (“Before the first use”) several times. Another reason could be that the ground coffee was stored in a hot, wet place for too long. Use fresh coffee grounds, and ensure you store ground coffee in a cool, dry place. After opening a pack of coffee, reseal it tightly and store it in a refrigerator to maintain its freshness.
