Black Maple?

[sbedilion]

3rd year tapping. I tapped some new woods and ran my first lines this year. 75 taps on 3/16...3 lines. After collecting 200 gallons+ and finishing with just over 2 gallons, I started to wonder what type of maple trees I was dealing with. I tested the sap and it's barely 1%.

Attached are some pictures. Are these Black Maples? I was told Black Maples are good sugar producers.

Could I expect my sugar to rise as the season progresses or is 1% all I can expect from these trees? I'm 400 gallons of sap into the season and only made 4 gallons. I'm only selling a small batch to cover cost...the rest will be for family and friends....so its not a huge concern. I might need to build an RO setup for next season to help.

Thanks!

Very cool, I've never heard of tapping black maple! Maybe PM Dr Tim Perkins, he's the expert.

ETA: Maybe they are good producers, in terms of volume. That doesn't necessarily mean a high sugar content, though.

Black maples are supposed to be up with Sugar maples, but only if they have a good top. It's the leaves that make the sugar. What diameter is the tree in the picture? it looks too small for 2 taps just judging the spile size related to the tree trunk. On gravity a tree should be at least 18" diameter to get 2 taps, about 20"+ if on vacuum. I don't put 2 taps until 23-24".
As the freeze thaw cycles become more frequent, the sugar does go up.

It's mostly around 18". I measured an 18" tree...hugged it, then just went from there. (treehugger...I know...haha)

I'm glad you mentioned the tops. I guess I never really knew that. My trees are close together and the tops probably aren't huge. They are on the edge of a field and get lots of sun, so they run really well.

Many of my trees that I tap here are black maples. Except for a different leaf, they are nearly indistinguishable from sugar maples. Black maples and sugar maples hybridize and create a tree that looks somewhere between them. Generally the sugar content and sap production are identical. Some literature indicates that black maples grow slightly slower than sugars.
