The Loire Valley Flashcards
Aside from climate, why has the Loire a long history of winemaking and trading?
- Ready access to the Atlantic
- home of the French kings until Louis XIV
- (before railway) its proximity to Paris allowed wine to be transported by river
Name the main wine regions and the main grapes of the Loire River (France’s longest)
-
Pays Nantais by the Atlantic
- Melon
-
Touraine and Anjou-Saumur (middle Loire)
- Chenin Blanc
- Cabernet Franc
- (Sauvignon Blanc in Touraine)
-
Central Vineyards (Sancerre, Pouilly Fumé 250 miles east of ocean)
- Sauvignon Blanc
- (Pinot Noir)
Loire wine production percentages by sub-region (2017)
- Anjou-Saumur 48%
- Touraine 24%
- = Pays Nantais 14%
- = Central Vineyards 14%
A few points about Pays Nantais
- Takes name from city of Nantes
- Close to Atlantic
- Main grape Melon (aka Melon de Bourgogne or Muscadet)
- Also Folle Blanche (aka Gros Plant) very acidic, sold locally and nationally
Climate in the Pays Nantais
- Cool maritime
- cool springs; warm, humid summers
-
Rain at any time Mar/April (flowering) September (harvest)
- but have well-drained soils
-
Spring frosts big problem (despite close Atlantic)
- esp 1991
- also recent years
- wind machines, heaters, burning straw bales
Describe Muscadet’s export market to the UK
- 1980s muscadet huge (13000ha planted)in
- 1991 severe frost cut production to 1/3
- pushed prices up when new world (esp Aussie) wines getting popular
- Now Muscadet repositioning as terroir-specific, high quality, good value (exports generally up 17% in 2015-16, not just to UK)
Vineyard management in Pays Nantais
- Canopy management (leaf removal) for
- max grape exposure/ improve ripeness (though beware sunburn of rows facing afternoon sun)
- reduce risk of fungal disease
- Attention to ripeness of skin/pips for harvest date
- but hot years risk high sugar levels before skins/pips ripe
Winemaking in the Pays Nantais
- Chaptalization up to 12% potential alc in cooler years
- Fermentation in large, shallow, underground, glass-lined, concrete vats (or stainless steel) to keep wine neutral, then age on lees.
- Avoid malo to keep acidity
Why might multiple passes be made when handpicking Chenin Blanc in the Loire?
- Chenin Blanc does not ripen evenly within a bunch and esp in cooler vintages, this can be a particular issue.
- To ensure the grapes are fully ripe, several passes may be made during harvest to pick the riper berries.
- This variety is also susceptible to botrytis. Botrytis attacks berries and multiple passes are necessary to pick those affected by botrytis (as opposed to grey rot) depending on sweetness levels for the style of wine.
Breakdown of who sells the wine in the Loire Valley
- Négociants sell 50% of all wine by volume
- top 10 négociants 82% of that 50%
- Estates 40%
- Cooperatives 10%
How has the relationship between estates and négociants in the Loire Valley changed in the last 20 years?
- It has become blurred
- Négociants
- increasingly opt to vinify, not buy finished wine
- have wineries the length of the Loire
- have bought prestigious estates
- Estates
- often now have négociant side of the business
- because of hail/frost crop reductions, may need to buy in grapes/juice/wine to keep clients
Give examples of (large) négociants which have bought prestige estates in the Loire
- Grand Chais de France
- Ch de Fesles (Bonnezeaux)
- Ch de Cléray (Muscadet Sèvre-et-Maine)
- Ackerman
- Ch de Varière (Anjou)
- Ch de Sancerre
Soil types in Sancerre
- Caillottes - v shallow (25-40mm) over limestone. Wines most aromatic, earliest to drink, least to age
- Terres Blanches - same limestone & marl as Chablis. Slow ripening. Wines most structured, ageworthy. Top vineyards Cote de Monts Damnés, Cul de Beaujeu
- Silex - flinty, accummulate heat = early ripening eg Les Romains next to Loire. Smoky, mineral wines.
briefly describe the process of ageing the wines of Pays Nantais “sur lie”
- Ferment and mature in large shallow underground glass-lined concrete vats (or stainless steel) to keep wine as neutral as possible (its the lees process gives flavour)
- After fermentation, racked off to remove gross lees
- Wine stays on fine lees through winter until bottling
- Sur lie wines must be bottled between 1 March and 30 November of the year following harvest and in the winery in which they were made.
- Ageing on lees increases body/mouthfeel of the wine while retaining freshness. often small carbon dioxide petillance - part of the style of these wines.
is chaptalization permitted in Muscadet?
yes, up to 12% abv potential alcohol
what are Clisson, Gorges & Le Pallet?
- three Muscadet cru communaux with l
- lower yields (45hL/ha v Muscadet AOC 65hL/ha, Muscadet sur lie and other 3 AOCs 55hL/ha)
- and longer lees ageing (too long for “sur lie”
- Le Pallet min 18mths
- Clisson, Gorges min 24 mths
- if grapes exclusively grown in these areas, can add name eg Muscadet de Sevre et Maine AOC Clisson
- wines are rounder, ore complex, longer finishes
why can Muscadet de Sevre et Maine AOC Clisson not make a wine “sur lie”?
- because it must be aged for minimum 24 mths on lees and “sur lie” must be bottled between 1 March and 30th November of the year follwoing harvest
name the four AOCs of Muscadet
- Muscadet de Sevre et Maine AOC (8800 ha - largest)
- Muscadet AOC (2nd biggest)
- Muscadet Coteaux de la Loire AOC
- Muscadet Cotes de Grandlieu AOC
why can negociants in Muscadet buy grapes, must or bottled wine, but not wines “sur lie”?
- because “sur lie” wines must be bottled in the winery in which they were made
flavour profile of Muscadet
- dry
- low intensity green apple, grassy notes
- high acidity
- light body
- acceptable to good quality (some v good)
- inexpensive
- “sur lie” adds texture and body to otherwise light wine, as well as often slight CO2 petillance
how does the climate change in the Loire Valley from Pays Nantais (Muscadet) to Central Vineyards (Sancerre)?
- spring in Sancerre 250 miles from Atlantic 2 weeks later
- overall climate cool, but moderating influence of Atlantic decreases progressively inland - Pays Nantais is maritime, Central Vineyards is continental
- in middle Anjou-Saumur maritime, Touraine continental
- rainfall high by coast at any time, 700mm in Anjou-Saumur/ Touraine at any time, 750mm in Central (less in summer), so fungal an issue throughout
- spring frosts a threat throughout
- river Layon in Anjou creates mist for botrytis
viticulture of Chenin Blanc (in the Loire)
- buds early (spring frosts), ripens late (autumn rains)
- vigorous, high yields
- powdery mildew, botrytis bunch/noble rot, trunk disease
- ripens unevenly, so limits mechanisation: for best quality (esp for noble rot wines) requires several passes
- dominant variety in middle Loire, nmaking sparkling, dry, off-dry and sweet
flavour profile of Chenin Blanc in the Loire
- dry (off-dry)
- medium intensity green apple, lemon (sometimes steely, smoky character)
- medium alcohol
- noticeably high acidity (off-dry balanced resid sugar)
- good to v good , inexpensive to mid-priced
- some outstanding/ premium (eg Dom Huet)
Viticulture of Cabernet Franc in the Loire
- early budding (spring frost) mid-ripening (pick before autumn rains)
- coulure (reduce yields)
- if not fully ripe, can taste excessively leafy, but leaf removal, avoiding dense canopy and warmer summers means happens less
- winter hardy (good for cool areas)
- in Loire used for single varietal or part of rosé blend
- in eastern Touraine blend with Cot (Malbec)
flavour profile of Cabernet Franc in the Loire
- dry
- medium to pronounced intensity red fruit (raspberry, cherry, blackcurrant), floral (violets), herbaceous (leafy, red pepper)
- light to medium body
- medium tannins
- high acidity
main grapes in Anjou-Saumur & Touraine
- Chenin Blanc (sep card)
- Cabernet Franc (sep card)
- Grolleau Noir (early bud, mid-ripen, blended in Rosé d’Anjou, Rosé de Loire)
- Gamay Noir (usually carbonic, Touraine and Central Vineyards)
- Cabernet-Sauvignon (let ripen, so temperate Anjou, only warmest sites, oft blended with Cab Franc, also rosé)
- Sauvignon-Blanc (Touraine)
- Cot (Malbec - Touraine)
what’s the main method of making rosé in the Loire?
- direct press (but some made by short maceration)
- wine-making as per white
- short ageing (3-4 months) in neutral containers
why can fermentation of Chenin Blanc in the Loire last several months?
- because it’s fermented at cool to mid-range temperatures to preserve primary fruit aromas and flavours
- (in large old oak or stainless steel for both ferment and maturation, malo avoided)
