Describe the climate of Prosecco DOC/DOCG.
- Warm and moderately continental
- Moderate rainfall
- The flat plain of DOC is affected by fog
- The hillier DOCG benefits from altitrude and higher diurnal range (longer ripening, higher acidity)
Why do the flatter plains produce lighter intensity wines?
The soils are more fertile, contributing to higher yields.
How is Glera trained and why?
- Long, typically vertically trellised with 8-12 buds because the first 2 do not produce much fruit.
Describe the harvest in the DOC/DOCG areas
- The DOC is largely flatter land and so machine harvested.
- The DOCG land must be hand harvested on the steeper hills but producers can choose hand/machine otherwise.
- Cartizze, Rive and sui lieviti wines must be hand picked.
