I just finished my 2020 season. This year did not go very smoothly but I made plenty of syrup. I tapped my trees on February 16. I was coming down with the flu so I didn't get to run the buckets for another week. I only collected two runs this year but they were both massive. I pulled my taps around March 10th. Sugar content averaged about 2.3% so I had my best yield ever at this location. I made 19.75 gallons of syrup on 740 gallons of sap. I don't sell it anymore so I shoot for 15-20 gallons. My RO worked great again this year and I ran it maxed out on pressure to minimize the amount of wood burned. I routinely ran 9-10% sugar and processed about 25 gallons per hour. I did two soap or lye washes at the end of the season and followed that with a 6 hour citric acid wash. My membrane tested above the rated capacity when I was finished cleaning and it has shown almost no loss in performance since it was new. Filtering was much better this year as I worked to keep my draw from getting plugged with sugar. I also decided to filter at 200 F or less and that worked much better. I believe I was making niter when I was heating to filter. I'm starting to debate how much longer I'm going to make syrup. I'll be 70 this fall and this year was miserable as I didn't feel well and I had to gather sap over 3 long days in the rain and snow. The mud and water in the woods was over the axels of my Kawasaki Mule. I don't have the option of using a vacuum or a gravity vacuum as my trees are scattered and the property is essentially flat. So I'll have to use buckets or bags as long as I continue.
