Burgundy Flashcards
main plantings for yonne and cote d’or
yonne 80% chardonnay
cote d’or 60% pinot noir
river of chablis
serein
market swings of chablis
- early 1900, famous for proximity to paris
- philloxera and powdery mildew problems
- paris railway helped cheaper wines to get transported
- rural depopolation after ww1
- 1945 frost
- back in demand in the last few decades
chablis climate
cool continental (cooler than cote d’or) cold winter and warm summers with considerable vintage variation (northern location)
average annual rainfall of chablis
670mm
rain problems in chablis
spread throughout the year, moist climate brings 1. fungal diseases 2. harvest problems (and rot)
soils of chablis
kimmeridgian soil (limestone and clay with fossilised seashells)
portlandian soil (hard limestone with less clay)
what is reducing yields in chablis?
- fungal 2. hail storms 3. spring frost
remedies for spring frost in chablis
- smudge pots (smoky, causes air pollution, requires staff)
- sprinklers (‘aspersion’) most popular option, expensive (also for staff and mantainance, so mostly only for top domaines/vineyards)
- pruning choices: later pruning for later bud-burst, reducing the chance of damage to the new buds from early spring frosts.
most used rootstocks and reasons
- 41B (vinifera x berlandieri), tolerate limestone soils with high pH
- 420A (riparia x berlandieri), low vigour, tolerance to high pH soils
training system used in chablis
double guyot replacement cane if one cane falls the other will survive
harvest in chablis
mostly machine picked hand picked only when is too steep for mechanisation

climat vs lieu dit labeling in chablis 1er cru
can use both the climat or the lieu dit after the 1er cru note
how many grand cru in chablis
1 with 7 lieu dits
chablis grand cru soils
kimmeridgian with crumbly marl and high clay content good drainage, water retention
chablis grand cru location
next to the village, south-west slope right bank of the river serein
chablis grand cru climatic feature
shelter from winds from the north thanks to a belt of trees
where in the slope are grand cru and 1er cru vineyards located
mid slope
advantages of mid slope plantings
- drainage
- frost protection
- better light interception (not too much, not too low)
chablis maximum yield
petit chablis 60 hL/ha chablis 60 hL/ha 1er cru 58hL/ha grand cru 54 hL/ha
is chaptalisation allowed in chablis?
yes and used constantly (not in warmer years)
main fermentation vessels
stainless steel concrete oak (mostly neutral)
winemaking techniques in chablis
mlf to soften acidity lees ageing to enhance texture
oak controversy in chablis and producers
depends on winemaker view but generally chablis should not smell of oak but in 1er cru and grand cru many uses it new oak (william fevre) old oak (dauvissat, raveneau) stainless steel/concrete (jean marc brocard)
negociants vs domaines in chablis
distinction is breaking down
negociants own land domaines have a negoce business
one third of production in chablis is vinified by
la chablissienne
producer associations in chablis
- le syndicat de defence de l’appellation de chablis (1993 by william fevre) 2. union de grand cru de chablis
le syndicat de defence de l’appellation de chablis main goal
combate fraud addressing environmental issues
union des grand crus de chablis main goal
voluntary association to promote quality (only limited to grand cru owners) sustainabl viticulture and hand picking mandatory
what drivers sales in chablis
both domaine name and appellation ex raveneau and dauvissat have premium prices for village wines
chablis export
2/3 are exported UK, USA, Japan, Sweden, Canada
climate of Cote d’Or, Chalonnaise and Maconnais
moderate continental Maconnais: drier and warmer 500km from the Mediterranean cold winters warm short summers (perfect for early ripening)
influences in Cote d’Or, Chalonnaise and Macconaise
Morvan Hills (in the west provide protection from rainfall)
annual rainfall level in Cote d’Or, Chalonnaise and Maconnaise
700mm
factors influencing quality of individual sites in Burgundy
aspect altituide degree of slope soil
main problems in Burgundy
cold weather frost hail eccessive rain drought
main problem of cold weather in Burgundy
under-ripe tannins in Pinot Noir
most problematic frost and result
spring frost reduce yields if they occur after budburst
damages of hails and periods
- early growth (april-may) can reduce yields or total loss of the crop
- later in the season fruit damage, grey rot risk
best techniques to get rid of hail or its results
- sorting table - to exclude damaged berries (hail is highly localized)
- hail netting
- thunderclouds with silver iodide to induce precipitation
hail netting in Burgundy
was not permitted because of shading permitted from June 2018 (limited use)
rain problems and timing
- flowering, fruit set - can disrupt, lower yields, and uneven ripening
- growing season - fungal disease
- before harvest - dilution (from water uptake), rot
drought stress main problems in Burgundy
berries shrivel and shut down (ripening halt)
how to combat drought in Burgundy
irrigation is not permitted plant in high clay content soils (bette water stress as water-retaining soils)
most critical factors determining style and quality of the wines of the Cote d’Or
aspect elevation
elevation of the cote d’or
200 to 400 metres
aspects in cote d’or
hills oriented north/south side valleys east-west main ridge is basically south east facing
location of best sites
south east facing middle slope
benefits of middle slope vineyard
- well draining shallow soils
- sunlight interception
- frost protection
- better ripening potential
disadvantages of top of the slope vineyards in the cote d’or
very poor, thin soils (vine cannot thrive as there’s not much soil) exposure to cooling winds
disadvantages of bottom of the slope vineyards in the cote d’or
- deeper soils (poorer drainage, more clay = more fertility = more shading = less ripeness)
- vulnerable to frost
coolest sites production in the cote d’or
aligote cremant de bourgogne
Cote Chalonnaise and Maconnaise best site locations for aspects
chalonnaise: bouzeron, rully (south-east)
maconnaise: pouilli fuisse (south)
general soils of burgundy
mix of limestone and clay
soils cote de nuits vs cote de beaune
nuits: more limestone
beaune: more clay, deeper soils
main soils problem in cote d’or
different depth of soil above the bedrock due to erosion (especially in lower vineyards in the slopes) e.g. Clos Vougeot
where is aligote mainly grown?
bouzeron (cote chalonnaise)
chardonnay ripening and budding state
buds early ripen early
chardonnay problems
spring frost (buds early) grey rot, powdery mildew, millerandage, grapevine yellows
best soil for chardonnay
limestone clay
chardonnay main feature
can produce high yields without loss of quality
challenge of growing chardonnay in burgundy good vintages
controlling excessive yield and shading from vigour (will reduce fruit quality)
budding and ripening of Pinot Noir
buds early ripens early
main quality problem of Pinot Noir
yields must be limited to produce quality wines
pest diseases and others on pinot noir
spring frost (buds early) millerandage, downy mildew, botrytis bunch rot, fan leaf, leafroll virus
pinot noir in warm climates
ripens too fast reduce aroma intensity berries shrivel suffer from sunburn
main goal in burgundy with pinot noir
making sure the fruit is ripen to have enough colour tannins and flavour
main clones of pinot noir
Dijon families (developed in the university of burgundy in dijon)
main points in selecting a clone of pinot noir?
yields diseases tolerance speed of ripening fruit characteristics
mass selection in burgundy
some producers will decide to plant a vineyard with different type of clones
fanleaf
virus brought by nematodes distorted leaves in a fan shape, turn yellow in patches shoot with distorted nodes and canes yields will fall and eventually stop only cure is destruction or removal of infected material replant with nematods resistant roots
leafroll
series of viruses, most damage brought by the mealy bug rolling of the leaves, turne bronze then red reduce yields as grapes will take longer to ripen eventually not reaching enough sugars replant vineyard
grapevine yellows alternative name
flavescence doree
grapevine yellows
phytoplasma organism spread by sap-feeding insects or infected material in grafting process curling leaves turn yellow ripening and yields are affected keeping vectors under control and eliminate plantes (like grass and weeds) that they are feeding on
