I grew up on the fake syrups, tried real syrup once and was enthralled at first taste.
I don't voluntarily use the fake stuff anymore, but I can stomach it fine enough.
As for syrup grading:
I'm pretty sure I've only ever bought Grade A (Kroger's Private Selection label). I absolutely cannot remember the specific, it was either Dark Amber, or... looking online, possibly Medium Amber.
I thought it was tasty, but that was/is the only pure maple syrup I have ever had iirc. Leagues, leaps, bounding jumps, miles, etc.. ahead of all that HFCS-laden artificially-flavored junk.
And yep, while it's wonderful to drown pancakes/waffles in the glorious syrup, with the real stuff, you can use less and still have it taste wonderful.
Back to this grading concept:
What, specifically, makes a lot Grade B versus Grade A? What's the difference in the Amber rating? How do these differences impact flavor?
Why is everyone saying the lesser grade is tastier?!
So am I to believe I need to find me some Grade B Dark Amber?
Oh, and real maple syrup is also the sugar devil: I try to limit sugar intake, but it is basically impossible to turn down real maple syrup. Though I do like, or at least don't mind, mixing the real syrup with some sugar-free fake syrup (is that double-fake?!). I would prefer not losing any of the real maple flavor or the real sugar, but it's not half bad once you get over the fact you've stooped to heathenism at the first meal o' the day.
