Foundation Flashcards
Old World vs New World
Europe vs everything else
True or False: The vine has very low nutritional demand.
True
The California Sprawl
New World grape growers planted their vines too close together relative to the vigor of the site and they compounded this, initially, by irrigating extensively.
This resulted in “California Sprawl” which is a tangled green giant of a vine intricately inter-woven with its neighbors.
Why can the old world plant the vines closer?
soils were unfertile, yields are naturally low
Cluster Primordia
next year’s crop
When was the first wine appellation d’Origine Controllee system created?
1935, Baron from Chateuuneuf-de-Pape
co-founded the Institute National des Appellations d’Origine (INAO)
What is AOC
Appellation d’Origine Controlle
a clearly defined area of origin from which a specifically named product can be created and labeled under strictly regulated production methods
Old French wine quality pyramid
AOC
VDQS
Vin de Pays
Vin de Table
The new French wine quality pyramid
AOC/AOP
IGP (formerly Vins de Pays)
Vins sans IG (wines without geographic indication)
How to be awared with AOC
- come from a delimited area of origin
- authorized grape
- adhere to a max yield
- strict regulation of pruning, harvesting, winemaking and ageing
What does IGP stand for
Indication Geographique Protege
Who regulates IGP
INAO together with AOC
VDQs
Vin Delimite de Qualite Supereure
aka: delimited wines with superior quality
The category was eliminated. It used to serve as an interim phase as wines transitioned from VDP to AOC status. , with the new EU regulations, VDQS status were upgraded to AOCor downgraded to IGP
Vins de Table/Vins Sans IG
table wines/wines without geographic indication
no links with origin
allows the mention of grape varieties and vintage on the label
Can come from anywhere in France
answers to no maximum permitted yields
labeled as “Vin de France”
exclusively for export markets
INAO’s goal
- polices and protexts its wine and spirit AOCs from wrongful marketing or misleading labeling
- policies and protects dozens of French cheeses and other French foodstuffs such as walnuts or lavender oil

What are the other names for Chardonnay?
Melon a’Arbois - Jura

Beaunois - Bourgogne
What is the other name for Chenin Blanc?
not related to SB

What is the north and south latitude for grapevine?
30-50
What are the northernmost planted region and southernmost planted for France?
champagne at 49-49.5 north
Corsica lies at 41 degree
What are the three major nutritional needs?
nitrogen, phosphorus and potassium
What are the six minor nutritional needs?
boron, copper, iron, magnesium, manganese and zinc
what are light sulfides
Yeast needs nitrogen to multiply. Lacking sufficient nitrogen in the juice, yeast end up scavenging for it. They break apart amino acids in order to release the nitrogen bound within these modecules. In doing so, sulfur is also released, manifesting themselves into aromas of toasted almond and roasted hazelnut.
Old World wine allow this natural process as it represents the signature of their soil. Many New World opt to add yeast nutrients.
December - March
grapevine branches are removed
chips and ash are returned to the vineyard and deposited between rows
March
bud break
shoot growth
When does flowering and berry set happen?
May
What month marks the transition of fertilized flower to grape?
May
July
Leaf pulling
Green harvest
When does verasion happen?
August
August
Verasion
the grapevine stops growing and starts to focus on the fruit.
grape berry change color and soften
sugar increase
acids decrease
October
Harvest
Fertilize the vineyard
cover the lower trunk with earth to protect them from winter freeze
November
leaf fall
prepare for winter pruning by removing fasteners and lowering catch wires
Most grapes are picked __ days after the grapes begin to change color and soften
45
Chasselas
very old grape variety
around Lake Geneva in Switzerland
Early Ripeners are harvested _ to _ days before Chasselas
Late ripeners are harvested _ to _ days after Chasselas.
8-10
20-30
Vines are most productive photosynthetically between _ and _ F.
68 - 86
No photosynthesis occurs under _ F or over _ F
50
95
Reflective stone is only effective if the ambient temperature is around __
50F
stomata
During the photosynthetic process, the carbon dioxide oxygen gas exchange occurs through small pores on the grape leaf called stomata.
These stomata are also the apertures whereby a grapevine transpires or releases water vapor.
When stomata is closed, there is no more carbon dioxide uptake and photosynthesis shuts down.
Phylloxera
a small insect indigenous to the eastern USA, kills the grapevine by attacking its roots. It injects saliva with each bite.
European vines, vitis vinifera, do not have the ability to heal over bite wounds.
Bacteria and fungi enter the plant and rot the root.
What is another name for European vines
Vitis Vinifera
How to resolve the issue of phylloxera in europe?
grafting European grapevine scions onto American rootstock.
What is the french name for “layering”
marottage
provignage
en foule
in a crowd.
Before Phylloxera, Rhone planted 1/3 of vineyard to __. Because of __, the number fell to 3%.
Mourvedre
taking poorly with the graft
Powdery mildew
Oidium
a fungal disease that is also indigenous to North America.
It blankets the vine with thick white filaments.
If an outbreak occurs before flowering, yields are reduced.
If the grape clusters become infected, they will not achieve full pigment development or grow to max size.
fruit off flavors.
Downy midrew
Peronospera.
Another disease from north america.
It germinates in warm, humid weather that it attacks the leaves and stems, first it appears as “oil spots” then with the white cottom filaments.
lose the leaves which can delay ripening or prevent it.
Alexis Millardet
Jura-born French botanist and mycologist
works at University of Bordeaux
developed “Bordeaux Mixture” or copper sulfate application to combat fungus attack
Worked with botanist Jules Emile Planchon to pioneer the grafting technique
Botrytis Cinera
fugus
have positive or negative effects depending on the condition in which the mold grows
positive: Noble Rot/Pourriture Noble, attacks tight-clustered grape varieties whose grapes are high in sugar content. penetrate the grape skin, desiccates the berry and concentrate sugar and other flavor compounds. dessert wine
negative: if the weahter stays cool and moist for too prolonged, noble rot turns to gray rote and can result in off flavors in the finished wine or crop loss.
What is the ideal climate to create Noble rot
cool, moist morning followed by warm and dry afternoons
Coulure
