100% Pinot Grigio. Sasa Radikon's created the so-called "S" line of wines (Sivi/Slatnik/RS) as a complement to his father Stanko's flagship wines (Jakot/Oslavje/Ribolla) to expand their range. While all of the vines are farmed and the wines vinified identically, the two lines are diffferent in several key ways. The "S" white wines are macerated for 2 weeks vs. 3 months; aged 1 year vs. 3-4 years (both in Slavonian oak botti); bottled in 750ml format vs. the groundbreaking 500ml/1L sizes; and touched with sulfur at bottling vs. zero for the traditional wines.

Sivi starts with organic Pinot Grigio bunches harvested by hand and destemmed. The berries are fermented with natural yeasts in oak vats with no sulfur or temperature control and a 10-14-day maceration The wine is aged in 3500-liter botti for a year and bottled without filtration and with a little sulfur. The name "Sivi" means "gray" in Slovenian, a reference to the natural grayish-pink color of Pinot Grigio skin.
