I cooked down 6 gallons today and have about 1 qt of syrup.
Boil it
If you aren't set up to boil out side, do it on the stove but have your vet fan running and have plenty of towels to wipe up the dripping. Get a candy thermometer find out the temp. water boils (it's 212 here) and just boil that sap down.
I started watching the temp when I'd cooked off about 3/4 of the volume (2 1/2 hours) and then watch it closely, get your temp 6-8 degrees over the boiling point of water (I hit 220 and think I'll go to 218 next boil) Mine is usually cloudy (mineral content) so I let it set overnight, then pour off your clear syrup the next morning
Good Luck
