I bought this refractometer from the Walmart marketplace. But I don’t understand its readings. It seems to say that it’s units are %v/v, which I assume means “% alcohol by volume”. That seems like a weird (maybe impossible) unit for refractometer readings, especially since the refractometer is supposed to be used BEFORE fermentation.
Does anyone know if there’s a correction/conversion/workaround, or should I just return this ASAP?
