CloudSpec Hazy Spectrophotometer
Use the CloudSpec device to measure colour and phenolics of juices and wines, hazy or clear.
CloudSpec's revolutionary spectrophotometer, developed in Wellington, New Zealand, is unlocking a new era of colour and phenolics analysis for wineries all around the world.
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.
Built for the modern winery
CloudSpec is designed with the modern winery’s needs in mind. It’s simple to use, massively reduces sampling times and generates powerful, understandable and actionable data.

CloudSpec is a game changer for analysing colour and phenolics. Unlike other systems that waste lots of time processing hazy samples like musts and ferments with expensive centrifuges, CloudSpec is so much simpler. Just take a sample, dilute as necessary, analyse in the CloudSpec and within 10 seconds, you have your results. The CloudSpec can save at least 10 minutes per sample compared to traditional analysis methods, which over the course of a busy winery year can translate into weeks of savings in lab staff time.

Simple, powerful results
The CloudSpec is a highly versatile device that uses full-spectrum UV-Vis analysis to measure wine quality with unprecedented detail.
After accurately recording the full absorbance spectrum of a wine sample, the CloudSpec then distills this modern data down into easily understandable classic and contemporary parameters, including:
- Colour - A420, A520, A620
- Colour Intensity (A420 + A520 + A620)
- Hue (A420/A520)
- Total Phenolics Index (A280)
- CIELAB
Colour
Phenolics
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.
Testing options
CloudSpec offers a suite of analyses, all focussed on quality parameters inherent in premium winemaking. Rapid and accurate tests for colour, phenolic, anthocyanin and total tannin made possible through the unique, proprietary CloudSpec platform.
Sampling
Sample at any stage of the winemaking process, from grapes in the vineyard, fermenting must in the winery, through to finished wine in the market.
Preparing
Simple preparation of samples (hazy or clear) from any stage of the winemaking process.
Analysing
Rapid analysis of hazy and clear samples through the CloudSpec proprietary spectrophotometer, simultaneously measuring all targeted uv wavelengths.
Uploading
Utilising the powerful CloudSpec Insights platform to inform winemaking decisions and assess quality parameters against regional and market competitive sets.
