Ch 1 part 2 Flashcards
TRADITIONAL METHOD- 2ND Fermentation
What is added to base wine to achive 2nd Ferm?
Liqueur di Triage
wine and/or must, sugar, cultured yeast, nutrients, clarifying agent (bentonite and or alginate)
TRADITIONAL METHOD- 2ND Fermentation
describe what the sugar does for 2nd fermentation
inside the bottle that is will be sold in
amount of sugar used will determine degree of effervescence
- fully sparking 24g of sucrose
- yeast convert sugar and will add 1.5% abv for every 24g)
- byproducts CO2 6 Atmospheres pressure
- yeast will ferment to dry
TRADITIONAL METHOD- 2ND Fermentation
2nd fermentation is often called?
often called Prise de mousse – capture the sparkle
TRADITIONAL METHOD- 2ND Fermentation
describe characteristic of yeast for 2nd ferm?
- cultured yeast that can work in unfavorable conditions
- commercially available that can start in alcoholic conditions (9.5-11ABV)
-Temperature of 16C or 61F - cool temp
-pH below 3
- withstanding of high pressures as complete ferm
- flocculate readily -form into small clumps/ masses
TRADITIONAL METHOD- 2ND Fermentation
describe the condition that bottle is in during 2nd ferm?
bottle is sealed with crown cap and small plastic pot for sediment
stored horizontally at 10-12C
length of fermentation depends on temp 4-6 weeks
slower can produces more complex finish
stable temp is important
TRADITIONAL METHOD- Less Ageing
temp for aging and length of time?
Temp of around 10C
Length varies depends on style fruity or lees character
Length influences price attained
Cava-9 months
For Autolysis to become detected needs 15-18 months
TRADITIONAL METHOD- Less Ageing
autolysis
benefits breakdown of dead yeast cells
continues 4-5 years
adds biscuit complexity
anti-oxidative quality to protect from oxidation
the older the wine the more it can withstand shock of disgorged
the longer the ageing, the faster it ages after disgorging
-once release for retail, ready to drink- they have done the aging for you
TRADITIONAL METHOD- Riddling and Disgorgement
choices for riddling?
Hand – placed into pupitres can take 8 weeks
Machine – gyroplattes for remuage 3-4 days
TRADITIONAL METHOD- Riddling and Disgorgement
Describe disgorgement?
may or may not be done by hand
bottles cooled to app 7C (45F)
cooling increase the solubility of CO2 & reduces gushing
neck immersed in bath of frozen brine freeze yeast sediment
bottle righted, remove crown cap, pressures ejects plug
liqueur d’expedition added
bottle is fitted with cork, wire muzzle, and metal capsule
TRADITIONAL METHOD- Riddling and Disgorgement
another name for dosage?
liqueur d’expedition -mixture of wine and sugar
added after 2nd fermention and at time of disgorement
RCGM Rectified concentrate grape must
TRADITIONAL METHOD- Riddling and Disgorgement
role of dosage?
top off the bottle
add sweetness
balance acidity which rounds with age
the older the wine at disgorgement, the smaller the dosage required
TRADITIONAL METHOD- Riddling and Disgorgement
Maillard reaction
reaction of the sugar in the liqueur d’expedition contained in the dosage with the amino acids produced druing autoysis after bottle fermentation.
encourages the development of roasted, toasted vanilla aromas
TRANSFER METHOD
what are the benefits of using the Transfer method?
developed in 1940s to save cost of manual riddling
retaining bready, biscuit notes form autolysis
reduces of bottle to bottle variation
easier to make final adjustments to wine
used to fill bottles smaller than 37.c cL and larger than 300 cL (sizes difficult for riddling)
TRANSFER METHOD
what is the reluctance in using Transfer method?
advancement in automated riddling have reduced significance need for method
TRANSFER METHOD
production method steps?
production is same as Traditional Method through to the step of 2nd ferm in bottle
- riddling does not take place in bottle
- fining agent and flocculation does not need to be added to Liqueur de triage
- wine is opened by a transfer machine and poured into pressurized receiving tanks.
- sweetened, SO2, sterile filtering carried out
