The only danger in mixing maples comes after the soft maples open their buds. In early season not an issue but soft maples open bud earlier than sugar maples, this year at my location it was over 3 weeks difference, more often closer to 2 weeks.
You should get a leaf identification book (or just the North American Maple Syrup Producers Manual) and learn to I.D. the maples when in leaf, then also study their bark, they can be identified in any season.
The white maple is most commonly called a silver maple.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
