So as you now know, I purchased a new refractometer without doing the research. No one to blame but me and Luc. Yep, that’s right, Luc. Not long ago I saw where Luc said something like, I always use my refractometer. So I got one and then learned that the alc distorts the reading. RunningWolf & Thetooth, told me about the distortion and referred me to sites with a formula to correct the distortion. Thank you to both, I tried it today and it does work, I think. You really have to start with a new must which I do not have at this time. The original brix must be known to get an accurate reading. Also, I normally use juice buckets that sometimes have already started to ferment when I receive them. Using my hydrometer readings I was able to back into the correct brix of an Amarone racked today and started in October, The meter said 7 and the formula corrected it to -3.3 or SG .987. My hydrometer substantiated it. Since I am really lazy, and don’t like the hydrometer, I’ll continue to use the refractometer and verifying with the hydrometer until I get more confidence in the it. But, Luc I would still like to learn how you use it.
