Typical order for red winemaking?

Packaging
What prevents extraction of flavours and tannins during fermentation in red wine?
Cap of grape skins on top of the juice
What are the two common techniques to overcome the problem of a cap in red wine fermentation?
Punching down
Pumping over
In rose winemaking, draining fermenting wine from the skins after a few hours is called what?
Short maceration
Short maceration in rose winemaking involves what?
Draining fermenting wine from the skins after a few hours of fermentation
Crushing and pressing grapes before fermentation will make a…?
White wine
Why are higher temperatures needed for red wine fermentation?
To extract colour and tannins from the grape skins
In white winemaking, lower temperatures during fermentation can result in what?
Fruitier aromas
To reasons for using oak during fermentation or storage?
Can directly add flavours to the wine
Can allow flavours to evolve because of interaction with oxygen
Oxygen does what to tannins during maturation/storage?
Softens the tannins
If a winemaker wishes to soften tannins during maturation and storage, what technique can be used?
Oak ageing
Is yeast used in malolactic conversion?
No
What substance achieves malolactic conversion?
Bacteria
Why is malolactic conversion not particularly important in red winemaking?
It nearly always takes place so is not noticeable
