Common Coffee Mistakes and How to Fix Them

There’s nothing more disappointing than brewing a cup of coffee, only to take a sip and realize it tastes… off. Whether it’s bitter, burnt, or just bland, bad coffee can ruin a moment of relaxation. But don’t worry—if your coffee isn’t tasting right, there’s usually a simple fix.

At Caffe Borbone, we believe that every cup of coffee should be rich, smooth, and aromatic. From our carefully selected coffee beans to our expert roasting process, quality is at the heart of everything we do. If your coffee isn’t living up to expectations, it might not be the coffee itself—it could be the way it’s stored, brewed, or prepared. Here are six common reasons why your coffee might taste bad and how to fix them.

1. The Coffee Blend

The quality of your coffee starts with the blend. If your coffee tastes flat or stale, it could be because the blend wasn’t stored properly. Coffee is sensitive to air, light, and moisture, which can quickly degrade its flavor.

How to Fix It:

• Store coffee in an airtight container, away from heat, light, and humidity.
• Avoid keeping coffee near other strong-smelling foods, as coffee can absorb surrounding aromas. Always choose a high-quality blend to get the best flavor.
• Premium coffee, like Caffe Borbone’s blends, is sourced from carefully selected beans and roasted to perfection for a rich, full-bodied taste.

2. The Water

Water quality plays a huge role in the final taste of your coffee. Hard water or tap water with a high mineral content can leave a bitter or metallic aftertaste.

How to Fix It:

• Use filtered or natural mineral water for the best flavor.
• Make sure the water is cold before brewing—using warm or hot water can affect extraction and flavor balance.
• For stovetop espresso makers like a moka pot, fill the water just below the valve for the perfect coffee-to-water ratio.

3. The Coffee Maker

The type of coffee maker you use—and how you care for it—can significantly impact flavor. For example, a moka pot can develop a protective coffee oil layer over time that enhances flavor, but if it’s cleaned improperly, that layer can be stripped away. On the other hand, buildup or old coffee residue can lead to bitterness or a sour taste.

How to Fix It:

• Clean your coffee maker regularly with hot water—avoid using soap or detergent in moka pots, as it can strip away the protective layer.
• Replace worn-out parts like gaskets and filters, as they can affect pressure and flavor extraction.
• If you’re using an espresso machine, make sure the portafilter and group head are free of old coffee residue.

4. Stir Before Serving

It might sound simple, but not stirring your coffee before drinking can cause an uneven flavor. The thick, richer part of the coffee tends to settle at the bottom, while the lighter, more watery portion floats to the top.

How to Fix It:

• After brewing, give your coffee a quick stir to blend the flavors evenly.
• Even if you prefer your coffee black, stirring ensures a balanced taste from the first sip to the last.

5. Old or Stale Coffee

Coffee loses its freshness over time. If your coffee tastes dull or stale, it may be past its prime.

How to Fix It:

• Always check the roast date before buying coffee. Use coffee within two weeks of opening for the freshest flavor.
• For the best results, try Caffe Borbone’s fresh coffee blends—expertly roasted and sealed to lock in freshness.

6. Poor Grinding

Grinding coffee too finely or too coarsely can throw off the brewing process and create bitterness or sourness. If you are using a grinder at home, be sure to adjust it according to the brewing method.

How to Fix It:

• For moka pots, use a fine grind.
• For French press, use a coarse grind.
• If you’re using ESE paper pods or Nespresso-compatible capsules, the grind is already expertly measured for the perfect brew. Check out our ESE paper pods and Nespresso-compatible capsules for a consistently delicious cup.
