Chiaror Sul Masso

Chiaror sul Masso is a Sparkling Brut fromTimorasso grapes, rating 13% alcohol by volume.
The grapes have been harvested in two stages: the first at the end of August, the second one at the end of September.
Both harvests underwent cold extraction (pre-fermentation) for approximately 48 hrs in temperature-controlled stainless steel vats.
Fermentation began spontaneously at low temperatures and continued slowly for about 3 weeks.
Standing on thin dregs was maintained until April , after which time the wine became clarified by sedimentation.
Re-fermentation continued in autoclave (Martinotti method) for about one month, followed by micro-filtration in steel at the end of August 
A few more points about Timorasso from Colli Tortonesi (Tortona Hills) and my relationship with it:
Timorasso is a rare vine stock, with white berries, cultivated within the Colli Tortonesi wine region by a group of tenacious wine growers.
