2017
Tapped out on February 18 - 99 taps (91 on 3/16" tubing with check valves and 8 sap bags)
RO - 6 - 150gpd membranes - processing 10gph at a 7.5% concentrate.
2/23 sugar dropped well below 1.5% the refractometer has not been very accurate so I re-calibrated on 2/28.
2/22-3/1 - temperatures were as high as 70 during the day and above freezing most nights.
3/2 - Boiled and finished off everything collected to date - flooded the pan with water - everything is empty in the woods
and the lines stopped running.
3/3-3/7 - Temperatures were only in the low 30s during the day and down to single digits at night.
3/10-3/17 - Temperatures dropped highs in low 30s and lows down in the 20s and teens - no sap runs
3/26 pulled the taps at 8AM there was another 170 gallons of clear sap nobody wanted it so pumped it to the ground. Out of wood and containers
but if I left them until April 2nd could easily of made another 10 gallons of syrup - will plan on more wood and containers for next year.
Totals for the year:
Season lasted 5 weeks
Gallons of sap - 2280
Gallons after RO - 405
RO removed 87% of the water
Averaged 67 gallons of sap for every gallon of syrup - sap was around 1.3% sugar which was .2 lower than our 18 average.
Total hours involved from collecting, boiling and filtering as well as tapping out and cleaning up 104. Averaged 3 hours for every gallon of syrup.
Total syrup produced - 34 gallons (14 dark and 20 amber)
