what happens to the fertility of soils on slopes
the further up a slope you go, generally the thinner and poorer the soil becomes.
Name a gap in the mayacamas that allows cool air to funnel through.
Chalk hill gap near castiloga
What does long hang time result in for grapes.
physiologically ripe grapes with ripe tannins, deep colour and quite high alcohol.
What are the two valleys in the central valley of Cali
San Joaquin valley in the south and Sacremento valley to the north.
What are the soils of the Central Valley
flat, free draining, sandy and clay loam.
True or False
Pump overs are a gentle technique that ensure even distribution of temp. between cap and liquid.
True
Are punch downs more or less extractive than pump overs. And when should they be carried out.
More extractive. Care should be taken to carry it out earlier as towards the end of fermentation tannins are more easily extracted.
Is rack and return very extractive?
Yes. The most. Usually only carried out twice during fermentation.
What does post fermentation maceration help promote?
polymerization of tannins.

What does Muscadelle provide to Sweet White Bordeaux
It is prone to Botrytis and provides a flowery, grapey characteristic.
The 3 grape varieties of Rioja and what they provide to a blend.
Tempranillo provides raspberry and black plum fruit with medium/medium (+) acidity and tannins. Garnacha brings sweeter red fruit character, lower tannin and more rounded body and alcohol. Some portions of Graciano may also be included in the final blend, which would contribute high acidity and tannin
