Thanks everyone for your hydrometer/hydrotherm suggestions. Maybe some day I’ll go the Murphy Cup route but not yet. I took my last batch too far it seems, and made some very thick ‘robust’ syrup. I usually take it off over and thin down to 67 brix as well, but somehow didn’t end up where I wanted to be. I might pick up a hydrometer and play around with it to see if it works any better than the hydrotherm for me.
