Throw out sap ice: really?

anyone who has taken a drink of sap out of a half-frozen buckets knows that freezing concentrates the sugar. I've seem almost totally frozen buckets where the remaining liquid was as thick and sugary as corn syrup (but, of course, with no maple flavor).

I don't have a sap hydrometer, but will have next season. I'm already sold on tossing the ice, but will be checking melted ice & sap for sugar content next year.
You should do the same 😃

Without a doubt, tossing the ice always results in shorter boiling times for me as well.
