[Q]: I love Twinings Lady Grey but the most recent batch was pretty bad. Regardless of how I brew it I get an odd odor that masks the characteristic Lady Grey aroma. I used some older tea under exactly the same conditions and got a perfect cup. I've got 6 tins of this stuff and it is a lost cause.
[A]: Negative

[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]: Negative

[Q]: On an untypically cool August evening we decided to try Melitta Riviera Sunset Decaf. I heaped in too much coffee and what we got was a bitter, overly heavy cup . I know others like their coffee to curl their hair with strong taste. We like it strong but not THAT much. On our next try we used less coffee and enjoyed a delightful semi-sweet cup of decaf. It was pleasing. Those who love strong, robust, full-bodied taste ought to definitely buy Melitta brand coffees.

Positive
