E8.24 LO 8.5 Classification of activities: winery Wallaby Gully Wines is a small, family-run operation in the Yarra Valley. The winery produces two varieties of wine, riesling and chardonnay. Among the winery's activities are the following: 1. Pruning: At the end of a growing season the vines are pruned, which helps prepare them for the next harvest. 2. Tying: The vines are tied onto wires to help protect them from the cold. (This also occurs at the end of the season.) 3. Hilling: Dirt is piled up around the roots to help protect them from frost. 4. Conditioning: In the spring, dirt is levelled back from the roots. 5. Untying: The vines are untied from the wires to allow them freedom to grow during the spring and summer months. 6. Spraying: The vines are sprayed in the spring to protect them from disease and insects. 7. Harvesting: All of the grapes of both varieties are picked by hand to minimise damage. 8. Stemming and crushing: Batches of grapes are hand-loaded into a machine that gently removes the stems and crushes the grapes.

Pressing: After removal from the stemmer/crusher, the juice runs freely from the grapes.
Filtering: The grapes are crushed mechanically to obtain more juice from them.
Fermentation: The riesling grape juice is placed in steel tanks for fermentation. The chardonnay grape juice undergoes a two-stage fermentation process in oak barrels.
Ageing: The riesling wines are aged in the steel tanks for about one year. The chardonnays are aged in the oak barrels for about two years.
Bottling: A machine bottles the wine and corks the bottles.
Labelling: Each bottle is manually labelled with the name of the vintner, vintage and variety.
Packing: The bottles are manually packed in 12-bottle cases.
Case labelling: The cases are hand-stamped with the same information given on the bottle labels.
Shipping: The wine is shipped to wine distributors and retailers, mainly in Sydney and Melbourne.
Generally, about 100 cases are shipped at a time.
Maintenance on buildings: This is done during the slow winter months.
Maintenance on equipment: This is done when needed, and on a routine basis for preventative maintenance.
