1.1 Traditional method Flashcards
What is liqueur de tirage?
Mixture of sugar, selected yeasts, yeast nutrients and a clarifying agent.
What is alginate?
A clarifying agent from seaweed extract to facilitate riddling
What decides the amount of sugar in the liqueur de tirage?
The degree of effervescence (bubblor) required. Usually 24 g sucrose per litre.
What happens during the second fermentaion?
The yeast converts the sugar to alcohol (about 1,5 percent for each 24 g per l) and CO2. Since the CO2 can’t escape te bottle, pressure is created. Usually 6 bar.
Does Liqueur de tirage affect sweetness?
No, since the wine is fermented dry.
What is Prise de mousse?
Capturing the sparkle. Also a name for second fermentation. Or a yeast-kind.
What is important for yeasts during second ferm?
Need to work between 9,5-11 percent, a moderate temp around 16 deg and also in PH below 3 and in a high pressure environment. Also, the yeast cells must flocculate readily do produce a coarse sediment helping riddling.
What is Sur Latte?
Horizontal storage during sec ferm. Usually takes 4-6 weeks.
What is true about temperature during Sur Latte?
10-12 degrees optimal. A cooler temp results in a slower fermentation, which is said to help gain more complexity. Important that temp is stable fora viable yeast.
At what temp should lees aging occur?
10 degrees.
What is the minimum time for lees aging in Cava, and what is the usual time on lees in the district?
9 months minimum 15-18 months more common.
What factors can affect the decision for time on lees?
Style sought.
Price to be attained
Financial ability to invest in longer periods of lees ageing.
What is the definition of autolysis and how long does it occur?
The enzymatic breakdown of dead yeast cells. Usually 4-5 years, can be 10 y
What is the main flavour characteristic fromautolysis?
Bread/biscuit
Why do some winemakers decide to keep the wine on the lees after finished autolysis?
The yeast cells have anti-oxidative qualities.
When should a R.D champagne be enjoyed and why?
As soon as possible since an older wine can’t withstand the shock of oxygen after disgorgement as well as a younger wine.
What are pupitres and gyropalettes and when are they used?
The storing facilities for sparkling wine after ageing sur latte. Pupitres - hand riddling. Gyropalettes, computer-controlled riddling (remauge)
How long does manual riddling vs gyropalettes take?
eight weeks vs 3-4 days
What is riddling?
Slow steady inclination towards the vertical cap down position. when turning bottle the lees flocculate and gradually fall towards neck of bottle.
What does sur pointe mean?
Storing of bottles upside down a few days before disgorgement.
How is disgorgement performed?
Bottles chilled to 7 degrees and neck immersed in frozen brine, which quickly freezes the sedimentnt easing its extraction and ensuring it doesn’t fall back into when when bottle is turned upright. Also, the cold increases the soluble of CO2 and reduces likelihood of wine gushing upon opening. the crown cap is removed and Liqueur d’expedition is added before bottle fitted with cork, wire muzzle and metal capsule.
What is Liqueur d’Expedition?
Mixutre of wine and sugar (dosage). Or RCGM Rectified concentrated grape must.
What does liqueur d’expedition do?
Tops up the wine and determines the sweetness of the final wine. The purpose is to balance the acidity.
What is the Maillard reaction?
The process where the sugar from the Liqueur d’expedition reacts with compounds formed during autolysis. It encourages the development of roasted, toasted vanilla aroma and if the bottle is allowed to rest before selling tese aromas become more integrated.
What can be said about Brut Nature?
Brut nature- no dosage. Uncommon since wines rarely have the balance, texture and complexity required to be able to taste pleasant when bone dry.
