Lees Contact/ Lees stirring - breaking up the sediment of fine lees and mixing it with the wine.

A

early budding - spring frost
- Chablis: apple, citrus, wet stones, slate (stainless steel, older oak after fermentation impact less flavour but allow a gentle oxidation to promote complexity)

Q

Cold Soaking /Cold Maceration

A

extract color and flavour.

Q

Cap Management in red wine making

A

Punching down - needs to be careful towards the end when tannins are more easily extracted.

Q

Whole Bunch Fermentation

A

Must make sure that stems are fully ripe - if not, tannins in the stems can give the wine an undesirable bitter taste
oxygen-free
- intracellular fermentation
A. Carbonic maceration
- uncrushed bunches only, filled the vet with CO2 to remove oxygen. 2% skin starts to split
- extracts color but little tannins, wine are soft and fruity, with notes of kirsch, banana, bubble gum and cinnamon-like spice
B. Semi-carbonic maceration
- premium Pinot Noir, alcoholic fermentation continues on the skin, fresher fruit character
C. whole bunches with crushed fruit

Q

cabernet sauvignon

A

thick skin, late ripenning; in cooler climate it can struggle to ripen fully - astringent tannins and herbaceous flavours

Post fermentation maceration may be used to encourage a more gentle extraction of tannin and to soften existing tannins

Q

Shiraz

New World

A

Australia - Hunter and Barossa Valley, soft earthy, spicy, with consentrated black fruit aromas
Australia (cooler region)- Great Southern, Geelong and Heathcote, produce leaner more peppery styles
Chile, South Africa, New Zealand- Hawke’s Bay, Washington state

17
Q

Syrah/Shiraz

Wine making

A

warm and hot area
- cap management extract maximum color, flavour and tannin from ripe and over ripe grapes
New oak add toasty flavour
cooler climate or harvest early
- gentle cap management
- whole bunches fermentation
- extended post-fermentation maceration may achieve fine tannin structure
older oak and larger vessels - more elegant, restrained wines

18
Q

Grenache

A

late ripenenig and needs warm or hat climate
tolerate for drought conditions
sweet, thin-skin grape
high in alcohol, low in acidity, full bodied with soft tannins and red fruit flavours
Destemmed and crushed, pre-fermentation maceration is common, extract more color and flavour before alcohol levels rise in fermentation.
some use whole bunches
stainless steel or old oak
gentle cap management such as punching down

19
Q

Garnacha

Spain

A

Priorat
- blend with Carignan, deep color, high tannin, fresh black fruit, toasty oak
Rioja (Rioja Baja)
- blend with Tempranillo
- contributes perfume, body and alcohol to the wine
Calatayud, Carinena and Nvarra
in hot climates Grenache can be jammy and high in alcohol and therefore often blend with varieties that more tolerate of heat such as Carignan and Mourvedre

20
Q

Grenache

France

A

South Rhone
Chateauneuf de Pape
- usually blended with Syrah and Mourvedre
- full body, rich texture, concentrated spicy red fruit
Languedoc and Roussillon
- blended with Syrah, Mourvedrtralia e, Carignan and Cinsault

21
Q

Grenache

New World

A

Australia - Barossa Valley and Mclaren Vale

old vines - ripe rubust wines with intense flavours of red berries and peppery spice

22
Q

Vine Species

A

Vitis Vinifera
American Vines - resistant to Phylloxera (a vine pest that attacks the vine’s roots) so they are widely used to produce rootstocks onto which Vitis Vinifera are grafted.

23
Q

Grape Vareity

A
  • Cutting
    a section of a vine shoot that is planted and then grows as a new plant
  • Layering
    a cane is bend down and a section is buried in the ground. The cane tip points upwards out of the ground. The buried section takes root and once the roots is established, the cane linking the new growth is cut.
24
Q

Mutation - Clone selection

A

Vines with positive mutation will be selected for further propagation by cutting or layering, so that the positive characteristics of these vines can be carried forward in new plantings.

25
Q

Cross fertilisation

A

create new varieties that able to thrive in certain climates and soil conditions, with improved disease resistance, and those deliver higher quality or quantity of grapes

26
Q

Crossing

A
A new variety is produced from two parents of the same species. Every grape variety used today is a crossing. 
Cabernet Sauvignon = Cabernet Franc and Sauvignon Blanc
Muller Thurgau (Riesling * Madeleine Royale)
Pinotage (Pinot Noir * Cinsault)
27
Q

Hybird

A

A vine whose parents come from two different vine species. Typically a hybrid will have at least one American vine as a parent.
- Root stocks

28
Q

Phylloxera

A

an insert native to North America. American vines are able to inhibit the underground louse by clogging its mouth with a sticky sap. They also form protective layers behind

29
Q

Bordeaux

A

moderate maritime climate
warming Effect of Gulf Stream: extends the growing season - spring frosts are rarely a problem
High level of rainfall and humidity
Rainfalls throughout the year can disrupt flowering and fruit set, promote rot and dilute the fruit flavours at harvest.
- Vintage variation is an important consideration in Bordeaux
- almost all red wines and most white wines are blend
