Another Question Regarding Holding Ro Concentrate

[john henry]

I have some fresh sap I just collected (@800 gallons) it is cold and has some ice in it from the buckets. Could I concentrate it tonight from @2% to @4% and cook it down tomorrow afternoon? I use a procon high pressure pump on my RO and it seems to bring the sap temp up very little. The sap is stored outside in the shade and will be kept there till I'm ready to boil. it is to be 20* tonight and barely above freezing tomorrow. I know there is a fair amount of info here on this subject but there are many variables... I don't mind making dark syrup as that is what I sell the most of. I can process @ 170 - 190 gph on my evaporator. I am looking to save work vacation time by RO'ing tonight and holding the sap over till tomorrow afternoon. if not I'll have to take some time off of work to get it done this afternoon and this evening. Thanks in advance for your replies!

You should be fine, I have done the same many times. At only 4% and kept near freezing it will keep. The day job always gets in the way of the passion. Before I got the bigger R/O we did this a lot R/O one night and boil it in the next, I didn't see where we really went that much darker.

Potters 3 - Thanks a lot for your comment - I am hoping to save some vacation days for the big runs... and yes it is hard to work the day job and always do all your many sugarin' activities at exactly the ideal time!
