structuresStore of carbohydrates
◍ Humus.
Answer: Partially decomposed organic matter
◍ What are the components of Integrated Pest Management (IPM)?.
Answer: Setting thresholds at which to take actionIdentifying and
monitoring pestsSetting up preventative measuresEvaluating and
implementing control options
◍ Organic viticulture.
Answer: Agentina, ustralia, Chile, Germany,France, Austria, California,
Italy,SpainCoexist with natural systemsEnhance biological cyclesIFOAM
guidelines- record all inputs- 3-year plan for a sustainable systemOptimum
soil structure & fertility- regular input of organic residues- micro-organisms-
cover crops- appropriate cultivation- composting- suppress weed, not
eliminate- no synthetic herbicides or pesticides- Bordeaux mixture &
sulphur allowed
◍ What are the 3 most common moth types?.
Answer: Light brown apple moth in AustraliaEuropean grapevine moth in
southern EuropeGrape berry moth in central and eastern N. America
◍ what is the T range for a cool ferment? what type of wine does it produce?.
Answer: 12-16C- fresh, fruity whites & roses
,◍ what is skin contact? what is its purpose?.
Answer: process of leaving the juice in contact with the skins to extract
compounds from the skins- to enhance the extraction of aroma and flavour
compounds and precursors, and to enhance the texture of the wine by
extracting a small amount of tannin
◍ How do birds damage vineyards?.
Answer: Eat the grapesDamage the grapes and allow bacteria and fungi
◍ Typical warmcontinental-climateregions.
Answer: MendozaCentral EuropeCentral Spain
◍ What is a viticulture practice that can delay budburst?.
Answer: Carrying out winter pruning late in the dormant period
◍ Vitis Vinifera is indigenous to where.
Answer: Eurasia
◍ Geneticmodification.
Answer: Transfer or modification of genes could improve disease resistance.
However, no genetically modified vines are currently in commercial use.
◍ How does vine vigours affect canopy management?.
Answer: Low vigour- drought stress (irrigation where legal)- low soil
fertility (fertilisation)- disease (diagnosis and treatment)High vigour (more
difficult to control)- low vigour rootstocks- water stress- cover cropping-
high density planting (low potential sites)- removing alternatie vines- root
pruning- complex trellis- pinching (shoot removal) ->lateral shoots- shoot
positioning, trimming,leaf striping, crop thinning orgreen harvesting
◍ Limestone.
Answer: Sedimentary rock from deposition of shells& skeletons of marine
life; mainly calciumcarbonate; alkaline & free draininge.g. central and
eastern Loire, Piedmont, NSpain, Burgundy, Limestone Coast Zone inS
AustraliaLimestone-rich soils inhibits uptake of iron& other micronutrients
(risk of chlorosis)
, ◍ Grapes in regions withcontinentality and longdays.
Answer: Early-ripening varieties- Riesling- Pinot Noir
◍ What influences the optimal vine density?.
Answer: vigor of vinetype of trellising systemaccess needed between the
vines
◍ Types of irrigation.
Answer: dripfloodchanneloverhead sprinklersflood
◍ Canopy management techniques?.
Answer: site assessmentvine trainingwinter pruningvine trellisingvigor
managementsummer pruning
◍ what factors affect extraction?.
Answer: T- t on skins- skin & juice management- solution (tannins are more
extracted in alcohol, anthocyanins are more extracted in aqueous solution)
◍ When is leaf fall and dormancy?.
Answer: Nov-March
◍ What does a bud contain?.
Answer: All the green parts; stem, buds, tendrils, leaves, inforescences
◍ Varietals that open at a higher temperature are referred to as?.
Answer: "Late Budding"
◍ What does photosynthesis produce?.
Answer: Sugars
◍ Where do new buds develop.
Answer: The base of the leaf stalks (petioles) on new shoots
◍ what are specific options to consider for white winemaking?.
Answer: skin contact (duration, T)- pressing (destemming, press options)-
hyperoxidation- must clarification- fermentation T/vessels- ML- barrel
aging- lees aging- packaging
◍ how do growers reduce the risk of frost damage when frost threatens?.
