I'm not sure Bascoms are tapping with the plan to get 9-10 weeks out of a taphole but with the number of taps they have they have to start early. Most all the really large operations do as well. Friends of ours have started they only have 6-7000 taps but there is only 2 of them and they milk cows as well. Can take them 3 weeks to tap. Yes they might get some early sap but they also might lose some at the end of the season from the same taps.
