If you sell your syrup I'd like to buy a jar.
LOL! Sorry, no; after doing this (on a VERY small scale!) since Valentine's Day, I've made 4 pints so far - and I gave away 2 of those at church!
Quote: Yes; the big thing is, it has to be during a specific temperature range - below freezing at night (the sap withdraws to the roots of the tree) and above freezing during the day (the sap rises in the tree, and some ends up coming out the tap). I marked those trees a few years ago, while they still had leaves on them; makes tree identification more certain. Specific maples (rock maples, sugar maples) give more & sweeter (higher sugar content) sap. Other maples give sap, but require a little more boiling. One of mine is a red maple, aka a "swamp" maple - I tap it anyway, and it works fine.
