Don’t tap mables. Sorry, the funny guy in me likes spelling, usually it is me. On the other hand, all maples are good, even box elders work. The deal is sugar content, some trees give more, some less, the boil down is what kills you. You’re looking at a 50:1 ratio, sap to syrup, that’s why it’s pricey stuff. I tapped the beer tree this eve also, flowing great, WI green death.
