Collected 175 gal sap on Wed 1/13 while weather was beautiful; sapsacks were huge bloated with sap. First try with my new evaporator arch made from an old oval oil tank. Much more efficient than setting the pan on concrete blocks. Finished the batch today, bottled 3.5 gallons (should have bottled 4 gallons but had an overboil on the stove, and we slightly overcooked it, I calculate that cost us a quart. So the ratio was 43.75:1 Beautiful gold color, had lots of sand so we used countless conical pelon filters inside the wool cone. FYI, Vieth Valley Farms near Marthasville MO (north side of MO river east of Hermann) is having an open house tomorrow 10-2. They make and sell syrup, have over 100 taps on tubing, sugar shack, and I think they have RO. They're on the internet if you want to get directions. John
