The hilly areas are marly, in parts sandy; this soil type allows the vine to produce specifically structured grapes rich in sugar.

The areas at the foot of hills are clayey giving the fruit structure and aroma. In the Faedis area, on the surface you find alluvial soil from the Grivò torrent with gross skeleton mixed with clay, producing sweet grapes rich in primary aroma.

Selecting the best agro-techniques for this vine, linked to the wine-making targets the winemakers adhering to the project have set themselves, is an objective we went for by visiting vineyards several times: to choose the best winter and summer pruning moment, correct soil management, appropriate fertilizer and the best plant pathology fully respecting the environment.

To rationalise agronomic intervention, we analysed territory climate data continually. This stage is really important as it allows winemakers to manage their vineyards with enough critical autonomy.

In the meantime, we began the search the Faedis town area and surroundings for vine-stocks and vineyards that were at least eighty years old, to collect bio-types to be planted in 2007 together with recognised clones available on the market, through sensitising winemakers to safeguard historical vineyards part of this particular area of Friuli.

These two years work have permitted us to single out the biotypes present all over the regional area, select and multiply them; to establish that 1600° thermal degrees are enough to guarantee good grape ripening in normal rain conditions; to state that the best soil for this vine is the sandy-marly type on the hillside and that the alluvial plain can provide just as good products by using an accurate, targeted vine cultivation technique; to analyse the cultivation and historical-cultural features of this ancient Refosco that has left evident traces in Friuli vine growing, finding further confirmation of the importance behind valorising it.
