D4 Sparkling Wines of France, Spain & Germany Flashcards
What problems can early-ripening Chardonnay encounter?
Spring Frosts
Coulure
Millerandage
Chardonnay disease risks?
Powdery Mildew
Grapevine Yellows
Botrytis Bunch Rot
What problems can early-ripening Pinot Noir encounter?
Spring Frosts
Coulure
Pinot Noir disease risks?
Powdery Mildew Downy Mildew Botrytis Bunch Rot Fan Leaf Leaf Roll
Why Pinot Noir & Chardonnay?
Early Ripening (harvested early to preserve acidity/sugar so needs ripe flavour compounds, helps avoid disease pressure) High Acid Chardonnay = Good Yields (without quality loss) & Neutral Flavours
Factors within grape variety that dictate style?
Intensity of Aromas
Acidity
Response to Autolysis (Chardonnay = Creamy; Xarel-Lo = Toasty & Smoky)
Why is healthy fruit so crucial?
Effervescence makes off-notes more obvious
Enzyme laccase released by botrytised grapes causes serious oxidation
Free Run vs Press Fraction?
Free Run - Light & High Acid
Press Fraction - Higher Phenolics, Solids and pH (i.e. less acidic); Faster Maturation
Benefits of Press Juice?
Good for shorter maturation wines i.e. for immediate consumption
What fining agents might be used where there is excessive colour or tannin?
Casein
Gelatine
PVPP
Traditional Method Fermentation Temperature?
14-20 Celsius; Retention of fruit flavours while hospitable to yeast
Traditional Method Fermentation Vessel?
Usually stainless steel - large volumes, temperature controlled, no flavour imparting
Traditional Method Yeast?
Neutral cultured yeast that copes well with high acid/low pH environments. Tank method wines from aromatic grapes may use one that also promotes thiols/esters.
Secondary fermentation, and fact that same strain used for both fermentations, means it needs to stand up to moderate ABV (10%), low pH and low temperature, high pressure, poor nutrients. Also, rapid autolysis and easy flocculation (clumping) for TM wines.
“Prise de mousse” [EC1118] most common.
MLC/MLF?
Where acidity needs to be reduced, or creamy texture added.
Diacetyl (butteriness) is metabolised during secondary fermentation.
Done to prevent it happening in bottle during SF; or sterile filtered if not.
Why Blending/Assemblage?
Balance Consistency Style Rosé Complexity Minimisation of Faults Volume Price
What can be in Liqueur de Tirage?
Wine Must Sugar Yeast Yeast Nutrients Clarifying Agents (e.g. Bentonite)
Traditional Method - How much sugar in secondary fermentation?
24g of Sucrose per litre (=~1.5% ABV increase)
French name for secondary fermentation?
Prise de mousse (capturing the sparkle)
How are bottles stored during SF?
Horizontally (‘Sur Latte’) at 10-12 Celsius. 4-6 weeks.
Lees Ageing Storage?
Horizontally ~10 Celsius.
Length of Lees Ageing?
Minimum 9 months for Cava
15-18 months provides detectable autolytic flavours
Autolysis typically stops after 5 years, but can go up to 10
The longer aged on lees, the quicker it develops post-disgorgement (so needs to be drunk quickly)
What do lees do?
Antioxidant
Imparting biscuity/yeasty flavours
French name for Hand Riddling Rack?
Pupitres
French name for Gyropalette Riddling?
Remuage
Length of time for riddling?
By Hand - 8 weeks
By Gyropalette - 3-4 days
Disgorgement bottle temperature?
7 Celsius (+ neck in freezing brine) Low temperatures increases solubility of CO2, reducing gushing
What can be in Liqueur d’Expedition?
Wine
Sugar (Dosage)
RCGM
Why Dosage?
Sweeten
Balance acid in younger wines, hence less needed for older wines
Encouragement of post-disgorgement aromas (via Maillard reaction) i.e. roasted/toasted vanilla
Why Transfer Method?
Less inter-bottle variation No riddling (less of an issue now automated) Smaller or larger non-standard bottles as hard to riddle
What is Transfer Method?
Chilled to Zero Celsius
Pressurised Tank
Added Dosage and SO2
Sterile Filtration
Ancestral Method?
Pet Nat
Can be cloudy, yeast deposit, cider flavours, unpredictable sweetness from incomplete fermentations
No SO2 so needs to be drunk early
Names for Tank Method?
Cuve Close
Charmat
Martinotti
Why Tank Method?
Cheaper (no riddling, autolysis, long-ageing)
Preservation of primary characteristics, for aromatic varieties
No secondary characteristics from Maillard, autolysis or oak
Tank Method Fermentation Temperatures?
16-18 Celsius to preserve fruit/floral aromas but prevent cool temperature aromas e.g. pear drop
Temperature to Arrest SF in Tank?
2-4 Celsius once at desired pressure/sugar/ABV
Lees Ageing in Tank?
Rarely - expensive, but can be used with automated batonnage at low temperatures (2-4 C) over ~9 months)
Pre-bottling for Tank Method?
Cold Stabilisation: Reduced to 2 Celsius to precipitate tartrates
Sugar Adjusment where desired
Sterile filtration
Tank vs Asti Method?
Asti:
Interrupted single fermentation
CO2 allowed to escape to reduce pressure
Sweetness Levels in Sparkling Wine?
Brut Nature 0-3 g/L [Zero Dosage] Extra Brut 0-6 Brut 0-12 Extra-Sec 12-17 Sec 17-32 Demi-Sec 32-50 Doux 50+
Body Protecting Champagne?
CIVC - Comité Champagne
Comité Interprofessionel du Vin de Champagne
Why is Dom Perignon Important?
White wine from black grapes Coquard press Blending across regions Reintroduced cork stopper Pioneered use of stronger English glass
Why is Veuve Clicquot Important?
Innovated riddling ‘remuage’ using pupitres
When was Champagne AOC boundary drawn?
1927
Échelle des Crus?
‘Ladder of Growths’ previously dictating grape prices; fed into grand/premier cru classifcations
Blocage?
Reserve wines - initially to reduce risk of bad harvests, later to provide consistency across vintages and improved quality through complexity
Annual Rainfall in Champagne?
700mm
Elevations in Champagne?
90-300m above sea level
Soil types in Champagne?
Chalk
Chalky Soils with Limestone Subsoil
