1. Sulfur Dioxide in Wine-Making

CleanFutures AquaSens (www.cleanfutures.com.au) is developing the AquaSens biosensor technology to measure the sulfite content in wines using a highly sensitive, portable device. As part of our market research process, we are interested in the importance of sulfur dioxide in your wine-making processes and how such a device might meet your needs.

Thank you for your participation. Note that your answers will be anonymous unless you agree to disclosure (See Q.10).

Impact of sulfur dioxide content on final price

* 7. What other sort of sensing tools do you currently use during the wine making process and for what? For example pH, Baume, temperature etc.

* 8. How do you classify the size of your operation?

* 9. If our proposed product would allow sulfur dioxide measurements to be returned from a small sample of wine in less than 10 minutes. How many portable devices would you consider to meet your needs?

* 10. Which wine region do you produce wine for? (Please state country and geographical indication).
