Ok for kids? Has alchole in it.

During the bourbon barrel aging process, a small amount of alcohol is absorbed along with the bourbon flavor. While the label states "up to 2% alcohol", lab testing shows it to average around 0.8% alcohol. Whether or not you give it to children is up to you, but personally I would have no hesitation. - Tamar Roman, Crown Maple LLC

How would this be to use in glazing a Christmas ham?

If you wanted. I use it on everything I’d put maple syrup in/on!

Is this a grade a dark amber? (formerly considered grade b)

Yes we use our Grade A Dark Color Maple Syrup to create Bourbon Barrel Aged Maple Syrup. Very Dark Color was "formally known as Grade B."
