I separate mine. It varies how much they but earlier year to year, but I remove the reds while I still get anywhere from 6-7 days more on the sugars on the short end, last year it was 20 days different. The 20 days was by far the longest between the 2 since 2003 when I started to make syrup commercially. I just like being able to quickly remove the reds from the lines. When I do that I just walk the mains, cut the lateral for the red lines and plug the section of the lateral that joins the main. Then when I have time after that I pull the taps. I know exactly which laterals are reds and around my sugarhouse it only takes me about 15-20 minutes to remove reds from the system. My taps at my lease are all sugars so there is no issue there.
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.
