viticulture/Vinification Flashcards
latitudes for wine growing
between 30 and 50
propagation
hybrid
cross
clone
hybrid - different kinds of vinis
cross - cabernet sauv
clone - reproducing a single vine
vine-training general spacing
high
low
close
far-apart
high - initial growth let climb higher to aid in airflow and sun exposure
low - less temperature moderation, cooler. good for hotter or more windy climates
close: more competition, less yield, more intense flavors.
far-apart: in nutrient poor soils. all vines have enough to share.
7 stages of vine’s lifecycle
dormancy/pruning weeping shoots flowering berries veraison harvest
vine-training styles
head-training
(cane pruning)
canes shoot out of the main head
cordon-training
(spur pruning)
spurs are the bumps that create new buds
head-training: each year trimmed back to the vertical trunk i.e. guyot, goblet (shoots kept short and stout bushes). each year grower has to decide what 10% will not be sawed-off
cordon-training - cordon extends to branches which keep growing. each year gower has to manage spacing of spurs (places where new growth come out of)
vine anatomy
shoot
cane
spur
shoot - new growth
cane - new growth once dead and hardened (+1 year)
spur - sawed-off stub from last year that will create new bud
Wine faults
TCA trichloroanisole Oxidation Volatile Acidity Ethyl Acetate SO2 Brettanomyces Hydrogen Sulfide
TCA trichloroanisole: corky
Oxidation: loss of fruit, damp cardboard
Volatile Acidity: vinegar, sharp, acidic
Ethyl Acetate: nail polish, chemical
SO2: egg, matches
Brettanomyces: barrel rot, funky animal smell
Hydrogen Sulfide: malnourished yeast, garlic and onions
