Refractometer question

[billyb56]

New at cider making. I bought a refractometer and know you can get a good reading on new juice but have been told that it doesn't work on fermented juice. However, Northern Beer has a calculator adjustment on their website implying you can take fermented readings. Any thoughts on this?

If you use Sean Terrill's calculator it's reasonably accurate for me. Within a point or so. If you just want to be sure fermentation is complete you don't even have to use a calculator

There are several of the calculators out there. I've been using the one on More Beer's site and it works very well for me.
