I discovered these when I moved to Canada a few years back.  Before this I had only experienced a thicker Wasa crispbread and was a bit put off at first.  The feelings dissolved the first time I ate one of these with light laughing cow cheese.  They are a little more "powdery" than I'd like, but they compliment most cheeses very well without overwhelming them.

It's high-quality and the price is right, especially with subscribe-and-save via Prime, but after months of trying to keep up with my subscription, I had to put it on hold.  I'm not a big water drinker, but this stuff has a distinct flavor and when you're using it as a work-out beverage four or five times a weak it eventually wears on you.  Or me, at least. I'd still recommend it, just don't OD the way I did.

Tastes like pine needles!!! I've had other earl greys before and never have I thought I was drinking pine needle tea (Another reviewer said it was a bergomot flavor, i'm not educated enough to know)...  I bought this for my wife who can't have caffeinated varieties, and I can say i'm not a big fan.  The English Breakfast decaf is EXCELLENT.  I prefer my tea black, hot or cold, but this earl grey is not tolerable unless drank with a splash of milk and sugar (splenda for me though). It is undrinkable as iced tea.  I'd return this if i could. Avoid this at all costs, young jedi.
