[EX 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.
[EX A]: Negative

[EX Q]: A fantastic product for pet treats,great smell and has freeze-dried liver treats beat by leaps and bounds. Owner of 2 fussy cockers.
[EX A]: Positive

[EX Q]: Bottom line, this made my cat projectile vomit. I've never had a problem with him eating Friskies before but, I knew "Cheezy Craze" just didn't sound right. It came as a sample in one of the larger bags. Not fun to clean up after partial digestion.
[EX A]:
Negative
