Roero Riserva DOCG Mario Costa is produced with only Nebbiolo grapes at an altitude of 310 metres, on sandy and well exposed soils.
It is harvested at the beginning/middle of October and vinified by soft destemming, fermentation in stainless steel with selected yeasts at controlled temperature and 30 days of maceration on the skins with frequent pumping over.
Refinement is in wood, for 30 months in 20 hl Slavonian oak casks and then in bottles for 12 months (bottles lying down).
This is a Roero Riserva with a brilliant garnet red colour. The nose is intense, with pleasant hints of plum that blend sinuously with balsamic nuances of dried flowers, as well as liquorice and sweet tobacco. The taste is enveloping, full, harmonious and velvety; it reveals intense balsamic notes and a long persistence.
The ideal serving temperature is 18 °C. It is served with rich, structured dishes, such as main courses of meat, cuts of lamb or kid, chops, or mature cheeses.
Production only takes place in exceptional years and in variable numbers.
