AHCPHT506
Manage a wine making process


Application

This unit of competency describes the skills and knowledge required to acquire grapes for processing and prepare for and produce a variety of wine types and styles.

It applies to individuals who analyse information and exercise judgement to complete a range of advanced skilled activities and demonstrate deep knowledge in a specific technical area. They have accountability for the work of others and analyse, design and communicate solutions to a range of complex problems. All work is carried out to comply with workplace procedures.

No occupational licensing, legislative or certification requirements are known to apply to this unit at the time of publication.

The candidate must provide evidence that they can:

acquire and process grapes for wine production

calculate the cost and logistical requirements of components of the wine production

identify and recommend improvements to viticultural practices that will contribute to enhanced wine quality in the next season

identify, establish, supervise and monitor daily cellar work practices

initiate and manage the fermentation process

make additions and finings as required

operate the filtration and bottling processes

operate the range of equipment required to process grapes from winery receival point to the fermentation tank

organise and undertake routine cellar operations

perform chemical analyses necessary for the winemaking process

perform must handling processes

plan processes that may be used to maximise production of grapes that meet winery quality requirements


Evidence of Knowledge

The candidate must demonstrate knowledge of:

principles and practices for managing a wine making process

'balance' in relation to wine taste

changes to the chemical characteristics of grapes during ripening, including acid, sugar and flavour

changes to the physical characteristics of grapes during ripening, including size, hardness and colour

climatic and physical features of wine grape growing areas and wine styles produced

equipment and processes for wine filtration

factors involved in the initiation and management of primary, secondary and malolactic fermentation processes

ideal Australian cellaring conditions

must and marc handling procedures

processes involved in handling grapes from the vineyard to the winery in order to produce wine

routine winemaking and cellar operation procedures including maintenance of a clean, safe working environment

ranges of equipment and using this equipment to process grapes and must in a winery

types and styles of wine produced in Australia

varieties of wine grapes in Australia

vineyard practices relevant to the production of grapes that meet the requirements of the winery
