Two days after placing the taps, we've collected almost a gallon of sap from two trees. A third has sap flowing, but the collector (aka milk carton) keeps blowing off the spile (aka ball-point pen shaft). All three of these trees are experiencing quite a bit of leakage around the spile because they're not tight in the holes, so the potential is there for much more sap to be collected (if you look back at that first picture, you'll see the sap leakage on the tree trunk). The fourth tap doesn't seem to have anything happening--we'll be moving that one soon.
Is it worth it, you ask? Especially considering you don't even like maple syrup, Scarlet, is it worth all the fuss?
My answer is absolutely yes. This experiment in syruping has already been so much fun and so educational. Can't wait to see how it turns out!
If you'd like more information, University of Cincinnati Clermont College has a terrific one page explanation of how to tap trees to make syrup.
