Cote d'Or, Cote Chalonnaise, Maconnais Flashcards
Climate
Continental with cold winters and warm summers
Relatively short growing season ideal for early ripening Pinot Noir and Chardonnay
Cote d’Or is moderated by the Morvan hills to the west
700 mm rain, early autumn typically dry but rain can be a threat at harvest, flowering and fruit set, mildew
Vintage variation is marked
Maconnais is slightly warmer and drier than Cote d’Or
Factors impacting site quality
Aspect, altitude, degree of slope, soil
promoting ripeness is a priority as at these climates ripening pinot noir is not guaranteed
Hazards
Frost can be a significant issue and decrease yields
Particularly acute as Chard and Pinot are both early budding
Exasperated by recent warm winters which promote early bud break
Hail: early in the season damages early growth and reduces yields, later damages fruit leading to rot
Anti-hail netting allowed since 2018. Also see thunder clouds with silver iodide to induce precipitation away from the vineyards. Careful sorting necessary
Can significantly reduce yields.
Rain (3 ways)
Drought. shriveled berries, stopped photosynthesis. Irrigation not permitted so water stress an issue. high clay soils do better
Topography
Aspect and elevation critical in determining style and quality
Cote d’Or lies on a low range of hills oriented north- south at 200m - 400m
Side valleys run east-west
Leads to many aspects being east, south, or south east
Best sites are on the mid slope (drainage, sunlight, frost)
Top of slope have poor thin soil, and exposed to cool winds
Bottom have deeper soils and exposed to frost
Coolest used for Aligote or Cremant
Soils
Various types of limestone and clay with varying proportions
Cote de Nuits is more dominated by limestone where best Pinot’s are grown
Beaune has more clay and deeper soils, highly regarded Chardonnay
Chalonnaise and Maconnais are a mix of limestone and clay
Depth of soil varies significantly partly due to erosion (even in gently sloping)
Thinner at higher elevations, deeper at lower. Top is too thin for vines, bottom is too fertile and vigorous (shading, no ripeness, no concentration)
Chardonnay
Very versatile and suited to a range of climates and soils for a range of styles
Buds early susceptible to spring frosts
Ripens early suitable to a cool climate
Can produce relatively high yields without a loss of quality
Prone to grey rot, powdery mildew, millerandage, grapevine yellows
Many top quality are grown on limestone / clay as in Burgundy
Chardonnay flavor
Cool: apple, pear, lemon, lime, wet stones, light to med body and high acid
Moderate: ripe citrus, melon, stone fruit, medium to medium plus body, with medium plus to high acid
Pinot Noir
Buds early prone to spring frosts
Ripens early suitable to cool climates
Yields must be limited to produce quality wine
Delicate and prone to millerandage, downy, powdery mildew, botrytis bunch rot, and fanleaf and leaf roll viruses
In warm climates it ripens too fast (reducing aroma intensity) and can suffer from sunburn
Sufficient ripening is a key concern in Burgundy
Clones
Many are drawn from the Dijon clone families developed at the Univ of Burgundy in Dijon
Widely used around the world for growing Pinot and Chard
Many in Burgundy use Mass Selection (better diversity and less disease prone but more inconsistent)
Pinot Noir flavor
Strawberry, raspberry, red cherry. village wines and above have light oak derived flavors (smoke, clove), low to med tannin (Grand cru have med plus), med alcohol, and high acid
Earth, game, mushroom with time in bottle
Pruning
Some Cordon like Cordon de Royat which limits yields and vigor though old wood can harbor disease
Traditionally was Guyot and many are now returning to this and to an even softer method known as Poussard-Guyot (maintains the same sap route from one year to the next with pruning wounds only on the upper part of the cordon. Reduces number of pruning wounds to cut down on incidence of trunk diseases like Esca
Requires skilled labor but worth it if it hinders trunk diseases and vigor
Vineyard Management (yields)
Planting density of 8,000 - 10,000 (some higher) to drive competition and and reduce yields
Debudding: but risks like drastically reduced yields if there is frost or other damaging things later
Green harvesting allows you to assess the vine before removing fruit and to take into account any weather. Can result in excessive growth in remaining bunches.
Yields
Regional appellations: 75 white / 69 red
Village level: 45 - 47 white / 40 - 45 red
Some grand crus: white 40 / red 35
Individual levels may differ
Vineyard Management Trends
Organic and biodynamic more popular
But climate makes this challenging
Many vineyards are shared and organic requires a minimum area to be successfully implemented
this can lead to friction between growers who want different practices
Pests
Grape moths are controlled via pheremone traps
Powdery, Downy mildew and bunch rot managed via canopy management and spraying
Recent outbreak of grapevine yellows
Esca and other trunk diseases
