CloudSpec

A novel tool that enables wine makers and brewers to monitor colour and taste, early and often.

A novel tool for measuring colour and chemical content of cloudy solutions without the need for filtering or time-consuming sample preparation - enabling wine makers and brewers to identify and monitor characteristics such as colour, tannins and bitterness in ferment.

Innovation overview

Currently, it's costly and slow - and sometimes not even possible - for wine makers and brewers to measure colour and taste at the early stages of production. CloudSpec is a new type of spectrophotometer that has the potential to revolutionise colour analysis in the wine and beer industries, thanks to its ability to analyse ‘cloudy’ solutions. Through its novel and patent-pending design, CloudSpec uses light to cut through the cloudiness of liquids and enable easier, faster and less costly monitoring of a ferment at the earliest stages of its development. This gives manufacturers the information they need, early on, about the factors affecting their ferments, enabling them to produce a consistent result each time.

Features

Faster measurements
No need to filter as samples can be directly pipetted into cuvettes and measured within seconds, saving valuable time per measurement.
Greater accuracy
The elimination of filtration and preparation steps means less user intervention and, therefore, less chance of errors being introduced into the results.
Better preservation of sample
Non-destructive testing means the sample is kept in its raw form, representing the nature of the product as it is in the bottle/ferment.

Applications

Wineries
Colour and phenolic extraction rates can be monitored to develop a year-to-year database of grape and variety behaviour for consistency and time saving.
Breweries
Colour and bitterness evolution can be monitored during ferment and throughout the brewing process.
Wastewater
Dissolved organics, algal blooms and product discharge can all be determined in highly cloudy waste streams.
