Hey Jeff, I'm not sure if sugar content actually does go up as the season progresses. But I really doubt that tapping higher on the trunk makes any difference re flow or content.

I have to admit, this is really freakishly early for me to tap so still a little hesitant. Maybe this is the mid-April blowout happening early, and by mid-March we'll all be done. But this weather is just too **** good and that little Surprise! has another 2l at least sitting there waiting for me this morning. So will check local long-term forecast first, but pretty sure all the other trees will soon be sprouting their their 3 pails apiece :-)
