At the end of two different years, this year and in 06, the last boil of the season produced the lightest syrup. I don't get it. I understood that the beginning of the year should be lightest and darken through the season. Is it that my cleaning technique for the tubing is inadequate ? Maybe the sap in the beggining of the year flushes out crud from the year before ? Seems odd to me
Any Ideas ?
