hey all, i got a simple question.... when you boil down the sap lets say 5 gals, and it reduces to not much, at that point when the temp hits 219-220 F deg. does that always mean that you have syrup? at that point? ... or do you also have to get the correct thickness also. im boiling my 3rd batch, and im trying to figure out at what point it i have syrup... and im boiling it right now!, nothing like asking last minute
