As long as the last batch isn't burnt, it will have the most maple flavor. That is either dark amber at the darker end of the scale, or grade B. Both are very good sellers for me. In fact, last year I made 335 gal, of which only 12 were light, 85 were medium,175 dark, 34 B and 29 C. Of those I sold out of my B first, And I blended 6 of my light in with my medium. I still have some light left, in all sizes but I had to buy a barrel each (40 gal med. and 30 gal dark) to meet my sales. The dark is my best seller, but while it lasts, B is my second best.
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.
