[EX Q]: Dynasty brand green tea is the best green tea I've ever tasted. It never tastes stale, unlike brands I've bought in grocery stores. This is because each tea bag is packed in a sealed envelope with a metallic lining. The metal apparently keeps out moisture.
[EX A]: Positive

[EX Q]: Because they brought bagels to America without which we never could get maximum level of enjoyment out of this delightful low cost caviar. Caviar for breakfast! We use the small soft plain bagels cut in two upon which we smooth a bit of cream cheese then a nice ring of caviar in the center of which is colorful and delicious cut up hard cooked egg then add a perfect cup of coffee. This is is best done on a week end so it can be savored ever so slowly--no stress involved--pure luxury. Yes, Yes, Yes, yes, yes.
[EX A]: Positive

[EX Q]: Got a sample of this today and was excited to try it. FAIL. When brewing it smelled great. It came out dark at first then quickly changed to a light watery colour. Very boring taste. I like dark coffee, my daily drink is Timothy's Midnight Magic Extra Bold. My wife likes Timothy's Morning Blend and prefers a light roast. Even she didn't like this coffee and said "it tastes like warm milk".
[EX A]:
Negative
