Sparkling Wine Flashcards
Where does the CO2 come from?
A secondary fermentation - yeast convverts sugar into alcohol and CO2
- a carfully measured amount of sugar plus yeast is added to wine
What is the legal def of sparkling wine?
more than 3.92 grams/litre of CO2
extra
- 1 atmospher pressure
- noticeable fzzy
When is carbon dioxide more soluble?
- higher pressure
- lower temperatuure
- higher alcohol
Where does champagne come from
a region of france tha focuses soley on sparkiling wine
-n01 else is allowed to use the name
champagne - cool continental climate average temp of 16deg, challenging for wine, sugars very low and acids very high
grapes include: chardonnay(light bodied wines and high acid), pinot noir -(greater body) pinot meunier(fruitiness)
PICKED AT LOW SUGAR LEVEL 18-20 BRIX
what are the characteriscs of the bas wine before it is turned into a sparkling?
- low alcohol
- high acidity
- low sulfur dioxide
- dry - no fermentable sugar
- neutral flavour
One method to create sparkling wine is METHODE TRADITIONALLE. What are its features?
also called classique, tradionale methhhod
- very labour intensive
produces high quality wineee
used in champagne
- also used in the best sparkling wines in other regions
wine ferments for 1-3 months
- blending to maintain consistency from vintage to vintage known as “HOUSE STYLE”
- Tirage syrup is added(seconayr fermentation
What does Tirage syrup contain?
Sugar, yeast reserve wine, yeast nutrients
How much sugar is aded METHOD TRADIT?
4grams/litre will tive 1 atmospher pressure
so to get 6 atmosphers add 24gperl
the alcohol will increase per 16g gl by 1% alcohol
what are some features of ageing en tirage?
- dead yeast slowly add flavour
- bread, biscuit, toast
- CO2 becomes fully disolved in the wine
- wine usually aged 1-3 years
MT define riddling?
- after maturation period yeast lees needs to be removed
- bottles are placed into riddling rack
- turned and tipped to move sedment into the neck
MT - what is Disorgement?
bottles placed in a very cold brine to freeze the sediment in the neck of the bottle
- bottles inverted upright
- the crown seal is removed
- Co2 pressure forces the frozen yeast plug out of the bottle
MT - define Liqueur d’expedtion’s purpose?
Lde is added to top up bottle(cane sugar, older wine, brandy)
sugar balances high acidity
cork is inserted
wine cage goes on so cork wont pop off
What is the transfer method? sparkling wine
same as MT : basewine + sugar + yeast are bottled
- no riddling
- bottles emptied into a tank
-filtered in bulk and liqueur d’expedition is added
rebottled
lable says feremented
What is the charmat tank process?
used for inexpensie spakling wine
- secondary fermentation conducted in tank not bottle
- basewine + sugar + yeast
- filtered and bottled at the end of fermentation under pressure
- no yeast flavour
- good for sparkling wines made with aromatic grape varieties
What is the asti method?
variation on the Charmat method
- used for asti frizzante and asti spumante
- muscat grape
- does not start with dry base wine
- stored close to freezing then warmed to ferment in pressurised tank
- co2 allowe to escaped until alcohol reaches 6% abv
- after this point, CO@ is retained
- ferment continues until 7-7.5%
define carbonation?
most inexpensive method
- co2 is injected into wine
- adds bubbles but does not alter the flav of the wine or add any other characterics to the wine
- not considered to produce high quality wines
Define applellation?
A geographical name given to wine to indicate the origin of the grapes used to produce the wine.
