Elements and Performance Criteria
- Analyse chemical components of wine
- Chemical components for a particular wine style are determined and where required, testing laboratories are identified
- Samples of grapes, juice and/or wine are taken according to standard sampling procedures and laboratory requirements
- Simple wine analysis procedures are performed and results recorded
- Results of chemical analyses are evaluated and compared with desired values to identify potential chemical problems in the winemaking process and any required additions or fining agents
- Resolve wine making problems
- Wine or juice is evaluated using standard laboratory and organoleptic procedures
- The protein stability of a wine is identified using a buttes or heat technique
- The need for cold stabilisation of a wine is identified
- Additives and/or fining agents are used to alleviate problems or improve quality, and their effectiveness is evaluated and their use adjusted where indicated
- Wine making and handling processes are carried out in a hygienic working environment
- Cellar operations procedures and instructions are clearly described, recorded and utilised during the winemaking process
- Taste and evaluate a wine
- Accepted tasting procedures are used for tasting the wine
- The flavour and aroma components and characteristics of the wine are identified using sensory evaluation methods
- The relative contribution and interaction of wine components to the wine taste, aroma and appearance are identified using accepted wine description terminology
- Characteristics of wine that make it suitable for cellaring and the ideal cellaring conditions are identified
- Tasting notes are made during the tasting process according to industry standards
- Records of wine evaluation are made and stored according to industry standards
- Analyse the effect of winemaking techniques on wine quality
- Evidence of the winemaking technique is identified in the wine to distinguish it from other influences on the wine
- Faults in the wine attributable to the winemaking technique are identified and distinguished from bottle age characteristics
- The effect of winemaking techniques on suitability of wine for cellaring is determined
- Analyse the effect of site characteristics, viticultural practices and grape varieties on wine quality
- Effects of climate are identified in the wine
- Effects of the physical characteristics of vineyard sites are identified in the wine
- Effects of grape variety are identified and analysed
- Effects of viticultural practices are identified in the wine and evaluated in terms of modifications and improvements to be made for the next season
- Viticultural production plan for next season is adjusted, documented and communicated to vineyard personnel
- Analyse current packaging methods, bottle closure methods and wine labelling laws
- The range of wine packaging available and used in the Australian wine industry are identified
- The range of wine bottle closure methods used in the Australian wine industry are identified and compared
- Current wine labelling regulations and their impact on the wine industry are identified and interpreted
