The Loire is France’s ____ River:
How long is it?
How does it affect climatic differences within the grape-growing areas (2)?
Key varieties and their appellations (5)?
- France’s longest river
- 400 kilometres long
- creates a number of distinct wine regions, w/ climatic zones and varieties specific to various regions
eg. spring in Pays Nantais = two weeks before Sancerre - Melon = Pays Nantais
- Chenin Blanc + Cabernet Franc = mid Loire (Anjou-Saumur and Touraine)
- Sauvignon Blanc = Touraine + Central Vineyards (Sancerre + Pouilly-Fumé)
- Pinot Noir (to a lesser extent) = Central Vineyards
What % do the 4 different sub-regions of the Loire Valley account for in terms of total hectares planted?
- Anjou- Saumur (37%)
- Touraine (31%)
- Pays-Nantais (22%)
- Central Vineyards (10%)
The Pays Nantais’ climate is heavily influenced by:
Main grape variety + 2 aka?
Peripheral local grape + aka?
Makes what type of wine?
- its close proximity to the Atlantic Ocean
Main: Melon (over 60% of plantings) (aka Melon de Bourgogne aka Muscadet)
Peripheral: Folle Blanche (aka Gros Plant)
=> very acidic wines sold locally and nationally.
Top 5 grapes planted in the Pays Nantais?
- Melon (dominant at > 60% of plantings)
- Chardonnay
- Gamay
- Folle Blanche
- Cabernet Franc
General climate of the Pays Nantais (2)?
Rainfall patterns + effects (3)?
What helps to offset these effects?
- cool maritime climate
- cool springs, warm + humid summers
- rain is a constant threat during growing season
- especially March/April => affecting flowering
- and September => affecting harvest
- predominantly well-drained soils help offset regular rainfall.
How have frosts affected the Pays Nantais (4)?
How are producers combatting this (4)?
- Despite proximity of Atlantic spring frosts = serious problem
- experienced detrimental frosts in ‘91
=> led to the loss a booming export market to the UK. - Frost continues to be a serious problem in recent years
- frost prevention measures
- particularly wind machines
+ heaters
+ burning straw bales.
General growing characteristics of Melon + suitability for its particular region (5)?
- quite a hardy variety
=> well suited to a cool region - buds early (prone to spring frosts)
- ripens relatively early => reduced threat of rain at harvest
- can produce high yields.
Melon’s disease suceptibility (3):
How does this affect production costs?
- good resistance to powdery mildew
HOWEVER: - has tight bunches => susceptible to downy mildew and BBR
- (both of which thrive in the humid climate)
Timely + repeated spraying is required, adding some cost.
Typical characteristics of Melon wine:
Acidity
Body
Alcohol
Aromatics
Special style
Blending partner?
Typical Quality + Price point?
- high acidity
- light body
- low - low end of medium alcohol
- low aromatic intensity (green apple)
- often made sur lie
- can be blended w/10% Chardonnay (basic Muscadet AOC, as of 2018)
- acceptable - good (some very good examples)
- inexpensive - mid-priced
What vineyard management tasks must be carried out in Muscadet due to its climate (4)?
- humid climate = close monitoring of vineyards + spraying to prevent fungal diseases
- cooler, marginal climate = open canopies and leaf removal to facilitate ripeness
=> max. exposure to sun + reduction of fungal disease risk - too much exposure => sunburn
How is harvest date (partially) determined in Muscadet?
Downside of this?
- according to ripeness of skins and seeds
- in hot years, danger = sugar levels may be to high before skins and seeds are fully ripe.
What adjustment may be made for Muscadet production in cooler years?
How is the wine typically fermented and aged + why?
How is MLC dealt with?
- Chaptalization permitted up to 12% abv PAL
=> practiced in cooler years - typically fermented + aged in large, shallow underground glass-lined concrete vats
- stainless steel also used
- Primary aim is to keep wine as neutral as possible and then age on the lees.
- Malo typically avoided to preserve high acidity typical of the style.
What fermentation vessels + methods are Muscadet producers experimenting with (4)?
Cost implications?
- skin contact
- fermentation in barrel
- amphora
- concrete eggs
=> these vessels add cost
What is ‘sur lie’ (2), where is it typical and what is its purpose (3)?
- highly typical in the Pays Nantais (Muscadet)
- increases body + texture of very light- bodied wines.
- retains freshness of wine
+ may be slightly effervescent (CO2) (part of style)
- After fermentation, one racking = remove the gross lees
- Then wine remains in contact with fine lees through the following winter and until bottling
What are the 2 larger and 2 smaller appellations in the Pays Nantais?
LARGER
- Muscadet Sèvre et Maine AOC (6,400 ha: Loire’s largest appellation)
- Muscadet AOC
SMALLER
- Muscadet Coteaux de la Loire AOC
- Muscadet Côtes de Grandlieu AOC.
Max. Yield for Muscadet AOC?
for 3 other Muscadet AOCs + sur lie?
Typical wine characteristics:
Sweetness
Flavors + Aromas
Acidity
Body
Typical Quality + Pricepoint?
Muscadet AOC = 70 hL/ha.
3 others + Muscadet sur lie = 55 hL/ha
- dry
- low intensity aroma of green apple and grassy notes
- high acidity
- light body.
- acceptable to good quality (some v. good)
- inexpensive
Additional rules for ‘sur lie’ aging in Muscadet (3)?
What production implications do these rules carry (2)?
- ‘sur lie’ may be added to the label any of the 4 appellations.
- must be bottled btw/ 1 March and 30 November of year after harvest
- must be bottled in winery in which they were made
- later bottling adds cost.
- négociants can only buy grapes, must or bottled wine, and not wine to be aged sur lie.
What are the ‘cru communaux’ of Muscadet?
3 most important?
What additional rules are applied (4)?
How are these wines different than regular Muscadet AOC?
Cru Communaux = 10 defined areas in Muscadet that may add their names to a wine’s label
eg. Muscadet Sèvre et Maine AOC Clisson
- Clisson / Gorges / Le Pallet
- grapes must be grown exclusively in defined area
- lower max. yield (45 hl/ha)
- must be kept on lees 18 months (Le Pallet) or 24 months (Clisson, Gorges) => adding cost.
- cannot be labeled as ‘sur lie’ (bottled after required date)
- typically rounder + more complex with longer finishes.
Describe Muscadet’s turbulent recent history in the market place (5):
What has the appellation done to promote quality (3)?
How much is currently exported?
- huge success in the UK in the 1980s
=> and as a result, 13,000 ha were planted - 1991 frosts = production drop by two-thirds
=> pushed prices up - couldn’t compete with emerging, inexpensive new world wines, especially Australian
- Muscadet has sought to reposition itself as:
- source of terroir-specific, high quality + _good value wine_s
Pays Nantais wine exports = 15% by volume
Importance of negociants in Pays Nantais?
3 significant egs?
Name of trade body that promotes Pays Nantais?
- Négociants account for over half of sales
eg. Castel, Grand Chais de France and Ackerman
InterLoire (Interprofession des Vins du Val de Loire).
- promotes Pays Nantais + Anjou-Saumur + Touraine
Top 5 grapes planted in Anjou-Saumur?
How does this compare to Touraine’s plantings?
- Cabernet Franc (> 40%)
- Chenin Blanc
- Grolleau Noir
- Cabernet Sauvignon
- Chardonnay
Touraine: Cabernet Franc also = #1, but Chenin Blanc + Sauvignon Blanc are tied for #2+3 (both just over 20%)
How does the climate change as Anjou-Saumur progesses into Touraine?
- moderating influence of the Atlantic Ocean decreases progressively (less and less as you go east)
- Anjou-Saumur = maritime effect is more marked.
- Touraine = continental climate (cold winters + warm summers)
What are rainfall patterns in Anjou-Saumur and Touraine?
How does this affect grape-growing (3)?
- Both have ~700 mm of rainfall (adequate for viticulture)
- falls throughout the year:
=> spring rain can affect flowering and fruit set
=> regular summer rain increases disease pressure
=> rain in late summer + early autumn can affect harvest.
How are the 3 main styles produced in Anjou-Saumur / Touraine allocated different vineyard sites + why?
Still wines = best-exposed sites
=> need a greater level of ripeness
Sparkling wines = lesser sites
=> need less ripeness
Botrytis-affected sweet wines = tributaries of the R. Layon
=> help create the misty conditions ideal for the spread of botrytis at the end of the growing season
What soils are found in Anjou-Saumur / Touraine overall + specifically?
What is the biggest PRO of these soils?
What rootstock considerations are in place (2)?
- wide range of soils including:
clay-limestone, flint-clay, sand, gravel and tuff.
Anjou = more schist + limestone Touraine = more chalk
- key PRO = good drainage + water retention characteristics of limestone
soils = high lime content
=> lime-tolerant rootstocks, eg. Fercal + Riparia Gloire de Montpellier protect vines from chlorosis.
Chenin Blanc growing characteristics (5):
Disease susceptibility (3):
- early budding (prone to spring frosts)
- late-ripening (autumn rains)
- but ripens unevenly
- vigorous variety
- can carry high yields.
- prone to powdery mildew
- botrytis bunch rot (both positive + negative, ie sweet wines)
- trunk diseases
Why does Chenin Blanc present harvesting challenges to grape-growers (6)?
- ripens unevenly
=> has to be picked on several passes
=> limits ability to mechanize - for Botrytized wines (eg. Coteaux du Layon)
=> multiple passes + picking by hand are necessary
=> these add to cost.
What styles of Chenin Blanc wines are produced in the Middle Loire (4)?
- wide range of styles:
sparkling / dry / off-dry / sweet
General characteristics of dry / off-dry Chenin Blanc from the Loire:
Aromas + unique character
Alcohol
Acidity
RS
Typical Quality + Price Point + top quality producer?
- medium intensity aromas: green apple + lemon
- (sometimes with a steely, smoky character)
- medium alcohol
- high acidity
- often balanced with some RS for an off-dry style.
- good - very good (w/some outstanding)
- inexpensive - mid-price (w/some premium)
eg. Domaine Huet
Cabernet Franc growing characteristics:
Disease susceptibility:
- early budding (prone to spring frost)
- mid-ripening (avoids autumn rains)
- winter hardy (good for cool areas)
- prone to coulure (reduction in yields)
What particular quality can some Cabernet Franc wines have + how is this avoided (3)?
General characteristics of Loire Cab Franc:
Aromas + Flavors
Body
Tannins
Acidity
- can be ‘leafy’ if not fully ripe
=> Better canopy management (avoiding dense canopies, leaf removal)
=> warmer summers in general
=> reduced incidence of overly herbaceous Loire Cab Franc - medium - pronounced intensity redcurrant, raspberry, violet
- sometimes leafy aromas
- light - medium body
- med tannins
- high acidity
How is Cab Franc typically used for Loire Valley wines (3)?
- single varietal red wines
- part of a rosé blend
- In eastern Touraine, blended with Cot (Malbec), as it Cab Franc typically cannot ripen as successfully.
