I wasn't getting much at all out of my 12 taps (I'm just a small time hobby guy with buckets). I added 3 more buckets Saturday, Sunday night and tonight I got 2 and 1/4 gallons each evening. That's out of 15 taps. I realize that's not a lot but for me it is, better than last year. It seems to be picking up so hopefully this weekend I can boil some down. I only have red maples and some silver (I don't tap the silvers as they don't seem to ever run for me)...maybe reds don't run sap as heavy as the sugars do? Not sure.
