Viticulture BEESTOP Flashcards
How does Biophysical factors impact the Nature
Impacts quality of primary production
Climate
- prefer Mediterranean climate
- 10-20 degrees
- long and dry summers
- cool moist winters for pruning
- impacts the time for grapes to convert nutrients to sugar influence flavor
Soil
- determine nutrients
- clay soil = more moisture hence better for red grapes
Others
- topography
- local site (disease and pests)
How does ecological impact nature
Monoculture - unsustainable practice
- Monoculture crops: Common mineral extracted from soil, leaving it malnourished. Narrowing the gene pool reduces resilience to pest and disease
Excess use of fertilizers and chemical pesticides
- contribute to global warming as it increases carbon dioxide produced
- pollutes run off
Water and energy intensive
Stats for how ecological impacts nature - how much land cleared
50000 ha of sustainable soil lost in Australia per year due to agricultural practices
scientifically proven that pesticides and fertilisers increase carbon dioxide production in plants
How does economic impact nature
capital intensive
- requires a high investment in land and technology in the NW
- high cost leads other vineyards subleasing/ selling their grapes to be bottled by larger companies e.g. Drayton’s bottles Suncorps grapes
Competitive advantage
OW - high reputation of high quality due to traditional methods = advantage in the demand for exclusive products
NW - highly experimental producing unique wine products (Tickled Pink, Hunter Blue)
- ‘value at every price point’ accommodates greater middle class consumers
Stats for how economical impacts nature
cost of land and machines
Cost of land = $50 000/ha
individual machinery costing more than $3 million
How does biophysical impact spatial distribution
- biophysical conditions determines spatial distribution to meet these requirements
- climate and soil
- OW - (Italiy, France) Mediterranean climate
- NW (Australia, North America, South Africa) quasi-Mediterranean
Disease and Pest - decrease production of grapes in areas where there is high amount of disease and pests
Disease powdery mildew - high rainfall areas
Phylloxera - native to the US and reach Europe in the 1860s
How does ecological impact spatial distribution (OW)
Divide between global ecological management emphasizes OW and NW
OW
- good at organic principles due to traditional methods (hand picking)
- appellation preventing artificial additives
bad at sustainable practices e.g. cover crop since don’t like to change tradition
NW
good at sustainable practice - renewable energy
bad at organic principles through use of pesticides and copper sulphate sprays
How does ecological impact spatial distribution (NW)
New world:
Slower to embrace organic principles, using pesticides and copper sulphate sprays to prevent growth of powdery and downy mildew of harsher climate
- 30 organic vineyards in Australia
- 50 000 ha of sustainable soil lost to Aus agricultural practices
- using whey to control the powdery mildew
Example of NW sustainable practices (2)
Drayton’s - 300 solar panel farm
Reyneke Wines (South Africa) = biodynamic vineyards which uses wild pea as a cover crop to re0introduce nitrogen into the soil
Impact of economic on spatial distribution
Fluctuation of average incomes
- 2008 wine glut steaming from financial global crisis saw over saturation of the OW wine market, decreasing consumption and thus production of wine in these areas
- COVID-19 increase in consumption due to increased leasure time due to lock downs mostly in NW
Opening new markets
- Asian markets (china)
- increase exportation due to increase acceptance of western flavours
Impact of biophysical on future directions
Climate Change - impact future harvest cycles
- moved vintage earlier by 1 day as temperatures increase
- decrease yields from weather irregularities
- promote pests and disease (more moist)
- vines experiencing weather irregularities disrupting dormant cycles
- causing earlier vintages, increase rain, drought and decreased yield
Example of the impact of biophysical on future directions
- southward shift - shift towards cooler climate in new world to combat climate change e.g. Tasmania
- 250 hectares planted since 2016 vintage
*2017 vintage report “ 13 000 tonnes from 2016”
Impact of ecological on future directions
NW shift to organic viticulture: demand for organic practices increasing as consumer knowledge into grape and wine quality, health and safety and environmental sustainability increase. Recognition of terroir calling for expression of soil naturally.
Organic wines
Push for organic production therefore less sprays
organic wine is based on producing natural, chemical free, biodynamic and sustainably grown wines. Ideally the grapevine happy coexists with other plants, insects birds and animals in a functioning ecosystem – not monoculture
Example of how ecological factors impact the future directions of viticulture
Blacksburg Vineyard = South Africa’s first carbon neutral vineyards
Avondale vineyards = duck patrol - natural pesticides which eats snails
Reyneke - bbiodynamic farm - integrating animals and plants to create a dynamic ecosystem - Trend putting cow manure in cow horns and burrying them underground for 6 months to make
Sustainability
- groundcover crops being introduced between vine rows to precent soil erosion, reduce compaction and increase the amount of organic material in the soil
- optimal fertilisation practices that reduce the amount of fertiliser used during the growth cycles of the plant
- leaf removal to allow air circulation and reduce fungal growth
- management of the supply of water to the plants through the use of drip irrigation
- use of biodegradable fungicides and promotion of biological controls
- reduce use of synthetic agrochemicals
Impact of economic on future directions
China opening trade
- Due to emergence of an affluent middle class = 75% of their urban population
- 48 million importers
- 0.5L/ year
- importing 340 million in 2022
- Increase targeting China’s industry e.g. Lafite 2008 vintage creating a bottle with the number of 8 = successful with bottle up to $14 000/bottle
Making wine more affordable due to changing demographic = targeting more younger female consumers (tickled pink)
