One word, yuk. OK, based on the 20 word minimum; barely edible dry, chalky, flavorless, not even improved or masked with a good slice of cheddar cheese.

Ex Output:
Negative

This was my first experience of a bad Darjeeling - before, I hadn't known there was such a thing. The first brew yielded a dark rust color tinged with olive-green. The bottom of the cup was invisible. The taste was sharp and astringent. Thinking I'd brewed too long or too strong, I set the first cup aside and tried again. And then again. A light brew of 3 minutes improved the clarity; however, nothing I have tried since has removed a level of astringency and a furred taste that I associate with lesser teas. The wet leaves are the typical size, light brown but unexpectedly interspersed with limp green squares.  The aroma of dry tea in the bag reminds me of old hay - neither moldy nor spoiled, just old. In contrast, the Davidson's Keemun Conjou which arrived in the same shipment smells and tastes like delicious Keemun Conjou and nothing else.  Given the price, I knew I was gamboling and consider this a lost bet. I have given the product two stars instead of one, because I haven't thrown it out (yet). I keep a supply of Lipton's bulk tea for emergencies such as long periods of unemployment, and I don't really need more emergency tea. Perhaps it will work for iced tea.  By no means am I an expert, but I do value tea, and so I hope this opinion helps other buyers who are trying to decide between two Darjeelings. Davidson's ships quickly with value pricing, and so I am not giving up on the merchant. Just on this particular Darjeeling.

I hope this may help others whose dogs love this treat like my fussy Lhasa Apso but she's nearly 16 yrs. old and I found she suddenly developed an insatiable thirst; which then caused so many frequent late night forays to go outside to relieve herself we lost hours of sleep. Thinking it was her age we let it go for awhile then I decided to take her off the varied brands of dehydrated chicken breast (all without additives) and within a week she no longer empied bowls of water and had to go out all night long. It may react on her differently because of her age but for others who may experience this problem you may need to take your dog off this type of treat...I'm now using the Purina Chicken Carvers (I know chemicals) but she no longer is having problems..go figure... I guess dogs are all different too huh?
