I have fallen in love with this tea. I am a british tea fanatic and Ashby's has superceded my tastes and expectations. Smooth, not to bitter, low tannins awesome taste! I'll take this over PG Tips!

Ew...I love Canada Dry and Schwepps, and I decided to try this brand because it was cheaper and it looked authentic. Not sure how the regular (non-diet) kind compares, but this tastes so diety--it's gross. I usually drink diet soda and don't mind the taste of diet coke, diet dr. pepper, diet sprite, (other diet gingerale, too) but this is REALLY GROSS. don't get it! You can definitely taste the ginger, but the overly saccharine taste ruins it.

Perfect size sea salt for the table or the picnic basket.  We love it. Shakes well, no clumping and flows freely.
