Q: Although it sounded delicious, I was very disappointed in this coffee. The coffee has a strange, chemical aftertaste ... cup after cup, not just once. Even when it brews, it creates a chemical sort of aroma. In fact, because our single-serve pod coffee brewer was new, I started thinking the problem was the brewer. We assumed it was a left-over manufacturing plastic or metal aftertaste coming through in the water. I even e-mailed the coffee machine maker (Bunn) to see how to remove the aftertaste. Imagine our surprise when a month later we opened a new pack of pods (regular Colombian, not flavored) and were delighted that our machine makes great coffee. When we made a cup of the Senseo Vanilla again -- back came the off-taste and aroma. Perhaps it's the "artificial flavors" used? Be forewarned!
A:
Chemical aftertaste - thought it was the coffeemaker, but it was the coffee
