I was wondering if anyone on this site had tried tapping and boiling the sap of anything other than maples. I did boxelder and some silver maples on some land we have this year. I don't have any black or sugar maples. It just seems like it would be interesting to see what it would be like to experiment with other trees. I know it can be done with birch. I have river birch, shagbark hickory, sycamore, cottonwood, black walnut on our property and would like to here from anyone on their results from tapping these trees. What does the syrup taste like etc.
