Hey Jeff. Nice to see the fever spreading. The bio stuff I won't comment on too techy for me. But when to tap! It's a big guessing game . was at a seminar in Perth on Sat and some of the big guys fig end of Feb this year. It always different but over an average of many years most of my syrup is made in April. Now I am not saying that will be the case this year or any year but just a average. This could very well be a early season given little snow and no frost. I plan to be all washed and lines flushed by last weekend in Feb. I have 600 taps so we can do that in a day if it comes on in a hurry. Watch your 14 day weather . watch your other local producers for activity in the bush . tapping too early can be worse than missing a day of the run! Good luck you will be fine.
