The refractometer in our Brix Kit is currently the most accessible of tools available for discerning quality. While not a measure of nutrient density, it is generally understood that the refractive index, or brix, of a given fruit or vegetable correlates closely to quality and taste. Refractometers are an easy, low-cost test widely used among growers for whom quality is important. But you don't need to be a farmer - you can just as easily use a refractometer on produce you buy from the store to get a better undertanding of what you are eating, or who has the best carrots at the market.
