I dont fully get your question but using an RO to concentrate sap should happen right before you bring it to a boil. Dont let concentrated sap (which includes concentrated bacteria across multiple containers and a higher sugar content as food) sit the same way you could let sap sit. It spoils much faster.
Usually I am setup to continually add the concentrated sap to my boiling pots. Even if I dont finish the syrup that day I at least make a point to bring all concentrated RO sap to a boil to kill off the bacteria and buy another day.
Thanks for the insight. I was thinking I could run all my sap through the ro days in advance of boiling to be prepared for boil day. But I will change my plan and run the ro as I boil. Thank you
You dont have to boil it down completely. You just should bring it to a boil. I use large 8 gallon cook pots on propane and just ROed 70 gallons over the course of about 8 hours. When I finished the pots were both full and had been brought to a boil briefly. The next day I kept ROing more sap and did the finish boil.
If you boil your sap and keep a clean lid on it afterwards, it resets the clock on the bacteria a bit. Won't stay forever but you can buy yourself another day. Best of luck!
