Using patented integrating sphere technology and novel algorithms, it can rapidly and precisely measure the colour and phenolics of grapes, juices and wines, even when hazy.
Examples of absorbance spectra produced by the CloudSpec for two different red wines, where the colour and phenolics regions of the spectra are clearly distinguished. Wine 1 has significantly higher phenolic content and colour intensity than wine 2.
