Guest guest Posted July 14, 2004 Report Share Posted July 14, 2004 Norm, But if, as Laurie says, brix is just measuring sugar content, then of course high brix produce would taste better.

Guest guest Posted July 14, 2004 Report Share Posted July 14, 2004 Good afternoon, My (mis?) understanding is that the refractometer measures the disolved solids in the juice. Yes if you grew a plant hydroponically in sugar water I expect the Brix meter would only measure sugar. However, I presume that a plant grown in healthy soil would have disolved minerals and nutrients as well. Does anybody know for certain? Thanks.

Guest guest Posted July 15, 2004 Report Share Posted July 15, 2004 Nick is right. Brix level tells you the percentage of soluble solids in the juice. I often hear people saying brix indicates sugar content. That's not exactly correct. It'll be the percentage of sugar content if you are measuring sugar solution and salt if you are measuring salt solution. A refractometer is a simple optical device which can not recognize it's sugar or salt in the juice. Refractometer was first invented for wine brewers to measure grapes before they make them into wine so they wanted to know the sugar content. I guess that's why people say brix is sugar content. We believe that the amount of sugar content is proportional to that of the other nutrients (protein, vitamins and minerals). I mean within the same variety of fruit, the higher the sugar content the more the other nutrients too. I think some highly hybridized fruit, like seedless grapes, probably contains mainly sugar. We can sort of tell by the demarcation on the calibration of the refractometer. The demarcation will be a clear sharp line if the juice contains mainly sugar and a fuzzy or blurred line when there are more other stuff. I imagine the other stuff make the light refract in different angles, thus they make the line blurred. Unfortunately I don't see fuzzy lines often.
