Gosh Karen, you had to tempt me with the refractometer again!
I feel like I'm boiling blind with my sap. Haha. I must say that I noticed that some of the rims on the buckets where the sap had dried off felt a little sticky. Maybe it's a higher sugar content? Or maybe just my imagination?
But didnt take long for the colour to change in the pans though - compared with the first boil of the season.

Well Im heading off to la la land. Want to get a headstart tomorrow before its supposed to drizzle. Not going to fight the rain boiling without a roof over my head.
