The WineCloud

The WineCloud is a web-based application that allows grape, ferment and wine data to be uploaded, analysed and stored in a secure environment online.

The WineCloud provides users with the ability to calculate tannin, colour and phenolics attributes in red grape, ferment and wine samples based on UV/Visible spectral readings. It also provides users with the capability to track and predict ferment profiles and to investigate the potential impact of different ferment management techniques. All data are stored securely and confidentially on the AWRI’s virtual private server. The WineCloud platform currently has three access options:

  1. Grape & Wine standard access (subscription cost applies)
  2. Grape & Wine standard + tannin access (subscription cost applies)
  3. Ferment Simulator access (free to access)

Standard access provides users with the ability to store, analyse and benchmark grape, ferment and wine analytical data. Standard + tannin access allows users to calculate tannin, phenolics and colour measures by using their own UV-Vis spectral data.

Pricing applies per SITE and there is no limit on the number of sites allowed per organisation.

The subscription fee includes the ability to analyse 100 blocks (grape samples) and 100 blends (wine samples). Any block or blend can be analysed multiple times and this does not impact on the total (remaining) allocation, i.e. each block/blend would only be counted once. Additional allocations of blocks/blends can be purchased at any time.

If you select Standard + tannin access, then you will need a UV-Vis spectrophotometer to collect the absorbance readings necessary to generate the tannin, phenolics and colour measures. There is a simple calibration process, which takes a week to carry out. This allows the AWRI to make sure that your instrument performance is reliable for generating the tannin, phenolics and colour data. Daily checks of a supplied QC standard are used to ensure ongoing instrument performance and allow you to process absorbance data.

For tannin, phenolics and colour analysis of grapes, there are two options:

  1. Measurement of total tannin potential – this also provides measures for total anthocyanins and phenolics, but requires a homogeniser and centrifuge for sample preparation.
  2. Measurement of extractable tannin – this does not require any additional equipment for sample preparation.

The Ferment Simulator allows users to predict ferment outcomes using basic temperature and baume data. Powerful algorithms also allow users to model the impacts of temperature, nutrients, mixing and re-inoculation and to respond to problematic ferments quickly during vintage. The Ferment Simulator is free and does not require users to access the Grape & Wine Portals. More information about the Ferment Simulator is available here.
