Last year for me was record low sugar. My season total was 1.25% sap, I usually average slightly over 2%. Last year mine never exceeded 1.8% and that was 1 day only. That being said, I got lots of sap, but if I had to boil straight sap I'd have quit far sooner than I did. My last collection and boil was 1%. I normally stop when it falls to under 1.7%. Had I done that in 2017 my season would have only been 3 days long, all sap after the 3rd day was under 1.7%. I got 1.8, 1.7, 1.7 ,1.6....it was soon at 1.4 and below.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
