What is the planting-density?
Medium density
What is sought to be the best soil? why is it not solely used?
Limestone soil - Most flavor-intensity and acidity
Plantings is also found on clay-soils, as the commercial success demands higher volumes.
What must be taken into account when deciding for a harvest-date? Inside and outside the grape
Inside: Acidity is key to balance the natural sugarlevels.
Outside: Autumn-rains in October must be taken into account, therefore harvest is typically in mid-september.

Describe the fermentation-process. How does is differ from a regular tank-method?
- Pressure-resistant steeltank is used
- One fermentation takes place
- Fermentation is done at 16-18 degrees
- CO2 is let out the vessel, untill the degree of alcohol is proper, then the vessel is sealed and CO2 will build up to wanted pressure.
- No Tirage
Does the juice undergo Malolactic fermentation? Why?
No - Acidity and fresh clean primary aromas must be contained.
How is the fermentation stopped?
Yeast is removed with filter under pressure
Old style Asti DOCG; At what level of alcohol did the wine had to be? And what did it mean to the style?
Wine had to be in-between 6-8% alcohol, meaning the residual sugar content would end up around 100 g/l, making the wine sweet.

The alcohol must be min. 6% - the wine has to be in-between Extra-dry and Sweet (12 - 50+ g./l sugar)
