I get around a shipment a week all year round from Amazon, and I can not remember ever writing a review. But I am making a point of expressing my anger over this product. I buy lots of tea from many sources and white peony is one of my favorites. The package says it is organic and of the finest quality. It was possibly the worst tea I have ever tasted. In fact, after a couple of pots, I actually threw nearly the whole half pound in the trash. And the price wasn't even that good. I subsequently bought a pound of excellent organic white peony from Whole Foods for less. Whatever they are, this is not a tea company.

My parents gave us this syrup (Dad's an Amazon Prime member, he gets EVERYthing on Amazon!) and we really enjoy the taste but we try to get Grade B syrup and wish Highland Sugarworks would come out with a B grade. We actually wrote them recently to make sure we just haven't missed it. Grade B is the healthy maple syrup, the REAL STUFF, and at first tastes a little darker than this and others you've had (which are almost surely the cheaper and more processed Grade A) but is far better for you and much healthier. If they can maintain this quality but offer a Grade B, we simply will NEVER get anther syrup brand again. As it is, we combine our Grade B which we get mail order from a place in Vermont right now with this since this has such a zesty taste to it.
