Mature wine in storage vessels | 6.1 Suitable maturation storage vessels to produce a given wine style are selected, obtained and checked for serviceability and use 6.2 Wine is transferred into the selected vessels according to determined wine style characteristics 6.3 Condition of wine in storage is monitored 6.4 Wine is bottled and sealed 6.5 Records are made and maintained |
Required Skills
Required skills Ability to: |
calculate the cost and logistical requirements of components of the wine production plan processes that may be used to maximise production of grapes that meet winery quality requirements operate the range of equipment required to process grapes from winery receival point to the fermentation tank perform must handling processes make additions and finings as required operate the filtration and bottling processes identify, establish, supervise and monitor daily cellar work practices |
Required knowledge Knowledge of: |

Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy holistically all of the requirements of the performance criteria and required skills and knowledge and include achievement of the following: acquire and process grapes for wine production initiate and manage the fermentation process perform chemical analyses necessary for the winemaking process organise and undertake routine cellar operations identify and recommend improvements to viticultural practices that will contribute to enhanced wine quality in the next season. |
Context of and specific resources for assessment | Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances. |
Method of assessment | Assessment methods must satisfy the endorsed Assessment Guidelines of the AHC10 Training Package and can be assessed holistically with other units Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of required knowledge Assessment must be by direct observation of tasks, with questioning on required knowledge and it must also reinforce the integration of employability skills Assessment methods must confirm the ability to access, interpret and apply the required knowledge Assessment may be applied under project-related conditions (real or simulated) and require evidence of process Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances The assessment environment should not disadvantage the candidate Assessment practices should take into account any relevant language or cultural issues related to Aboriginality, gender or language backgrounds other than English Where the participant has a disability, reasonable adjustment may be applied during assessment Language and literacy demands of the assessment task should not be higher than those of the work role |
Guidance information for assessment | To ensure consistency of performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities. |
