Technical information about yields, elevation, soils, fermentation temps Flashcards
What is the max yield permitted in Champagne?
- 79 hL/ha
- may be raised to 98 hL/ha
- volume over 79 must be placed into reserves.
What is the elevation range in Champagne?
90-300 meters
What is the planting density in Champagne?
8000 vines/ha
What are the typical fermentation temperatures for primary and secondary fermentation in Champagne, and why? (or any traditional method sparkling wine)
Primary: 57-68 degrees F to retain fruit flavors but ensure temps are not too cold for yeast.
Secondary: moderate temperature around 61 F
By what percentage does secondary fermentation raise the alcohol level of traditional method wine?
1-2% which is why low potential alcohol is important for grapes at harvest.
What is the climate of Champagne?
Cool continental with oceanic influence
What is one of the most common yeast strains for traditional method wines?
EC1118
In traditional method wines, what is in the liqueur de tirage?
wine and/or must, sugar, cultured yeast, yeast nutrients, and a clarifying agent such as bentonite and/or alginate (a seaweed extract to facilitate riddling).
The amount of sugar in liqueur de tirage depends on what?
The amount of effervescence required. In most fully sparkling wines, 24g of sucrose per liter is added.
In traditional method wines, what is in the liqueur de expedition?
mixture of wine and sugar. the sugar is referred to as the dosage
What is the role of dosage?
balance the acidity
What is the Maillard reaction?
The sugar in the liqueur d’expedition reacts with compounds formed during yeast autolysis which encourages the development of roasted, toasted vanilla aromas.
Residual sugar in Brut Nature?
0-3 g/L
*important to note that dosage cannot be added to Brut Nature wines. Any slight residual sugar present remains naturally after fermentation.
Residual sugar in Extra Brut?
0-6 g/L
Residual sugar in Brut?
0-12 g/L
Residual sugar in Extra-Sec/Extra-Dry?
12-17 g/L
Residual sugar in Demi-Sec/Medium Dry?
32-50 g/L
Residual sugar in Sec/Dry?
17-32 g/L
Residual sugar in Doux/Sweet?
50+ g/L
Climate of Cremant d’Alsace?
Sunny and Continental
Elevation of Cremant d’Alsace?
200-400m
Max yield of Cremant d’Alsace?
80 hL/ha
