I’ve read that sugar maples produce the sweetest. We have about 15 or so in our yard, and I only tap 8 each year to get 40 gallons of sap for me, and 40 gallons of sap for a friend, who cooks his down himself. It only takes two weeks or so from the time they start running, to collect the 80 gallons. We use two taps per tree. We also have a dozen red maples. I’ve learned that they run later than the sugars, and after tapping them one year,honestly, I can’t tell the difference in the flavor of the syrup.
Have tried all kinds of home-made ways of collecting, but have settled on the Chinese Sap Sak holders (no, not a joke) available at Andersons. Very convenient to hang a 4 +/- gallon heavy duty bag they sell separately. Convenient to pour into collection buckets and re-hang for more collection. It hangs on one tap, which dispenses directly into the bag, and you can run a small hose into the bag from a second tap.
Anyway, there are some good tips on here for cooking and filtering the sap. Might try the egg tip for my second batch.
