You have a problem if you are dealing with red wine as the red pigments mask the colour changes. In that case you have to extract the ethanol from the wine (in effect, by various forms of distillation) and carry on, as above, from there. Canterbury University NZ has quite a simple method for red wine: see . Chemistry teacher Emma Hodginkson from Mountain Creek State High has performed the Canterbury ethanol titration with her Year 12s for a few years and has found it very successful. When analysing commercial wine, her students get very close to the %alcohol on the label. As it is a redox titration she says it works better in Year 12 when the students have completed some redox theory whereas Year 11s find the calculations a bit heavy going. To overcome the practical difficulty in locating a small container to suspend above the dichromate - they use a plastic water bottle lid suspended with cotton thread. Cool!

You could take some wine and add ethanol to it as the independent variable. The problem is - where do you get ethanol from? Your school may not have a licence to buy 100% (absolute) ethanol, or even the 95% azeotropic mixture (with water) so you may have to distill your own from shop-bought wine (ask your teacher before you bring any to school). From the density of the distillate (use an SG bottle) you can calculate how much to add to some fresh wine.

Sulfur dioxide should prevent the growth of acetic acid bacteria in wine and is sometimes used commercially for this purpose. SO2 in wine consists of the free form (molecular SO2, bisufite ions HSO3-and sulfite ions SO32-) and a bonded form. At normal wine pH only about 5% of the free SO2 occurs in the molecular form (which is the most active anti-microbial form) and the other 95% as bisulfite and sulfite ions. Concentrations of up to 20 mg/L of free SO2 will kill the bacteria.

There is one main way for measuring total acidity and that is with a titration against sodium hydroxide using a phenolphthalein indicator. There is a problem in measuring acidity is when you have red wine as the pigments disguise the indicator colour change. Chemistry teacher Gareth Whittaker from Mary MacKillop College, Brisbane, advises the use of a pH probe rather than an acid-base indicator; and titrating to an end-point of pH 8.2 (this is called a titration to distinguish it from a titration which uses a colour-change indicator). The method he uses (O24A-FD) comes from the , AOAC. to download a copy. A pH of 8.2 is the international standard for TA endpoints in wine.

For teachers who would like to have a basic introduction to wine chemistry or would like to have a refresher, the Queensland College of Wine Tourism at Stanthorpe offers a professional development workshop that may be useful. No recommendations are made as it is up to teachers to check it out (but reports have been good). It is called the "Teachers Wine Chemistry Professional Development". Teachers are provided with an overview of the wine production process and the chemical processes/analysis that are conducted at each stage of wine production with an emphasis on the importance of chemistry concepts to quality wine production. The other program of interest may be the Senior Studies Wine Chemistry Residential Program for Year 11 and 12 students doing a wine chemistry EEI. It is a 2-day practical program delivered by a qualified winemaker and costs $90 per person (meals and accommodation extra). No recommendations are made here but more information is available for or on their .
