I tap about 600 sugars, 50 reds and 150 silvers. Sap gets mixed in and all boiled the same. Throughout the season, the sap % is all about the same. My reds & sugars are in the hillside competing with other hardwoods, my silvers are on the creek bank and have huge canopies. Sugars and reds are on steep hillsides, 3/16 gravity, they average 1.5 gpt/day, silvers are level, on 3/16 pulled by shurflos, average 2 gpt/day.
