If you get the Brix high enough that it doesn't ferment you don't have maple syrup you have a locally adapted biological innoculant for maple trees. That's so expensive to buy because I just made the idea up and I am not as young as I used to be so it taken literally decades to come to that thought. 💸🫠💸 Now I am not a sugar maple expert but I would assume the basic biology is the same across all Acer's though- I think the north american ones evolved without worms so it might need to be tested/researched a bit. However if you found it helped on Japanese maples you have a whole bunch of Bonsai enthusiasts and landscape gardeners to sell to. Japanese maple prices are frankly insane.
