Around my sugarhouse I'm about half and half, sugars and reds. I'm on 26-27" vacuum and I got .52 GPT syrup 2 yrs ago and .48 GPT last year, that is 1/2 gal of syrup average the last 2 seasons, before that I had far fewer reds but never got over .38 GPT, but my vacuum was less too.
Reds do make some very fine syrup for sure.
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.
