Founded in 1954 by Josef Petric, this small family winery is located in Planina in the heart of the wine growing region of the Vipava Valley. Fervent ecologist, Jozef has followed since the beginning a sustainable agricultural approach.
In 1956, the winery receives an important recognition for having saved and valued the indigenous Pinela.
When in 2005, his son Zmago took the reins of the company, he baptizes it “Guerila”. “I wanted a provocative” name says Zmago. The message is clear: this is a rebellion against the abandonment of local varieties in favour of more productive, commercial varieties by many producers.
The vineyards are spread over 10 hectares on terraces of the meridional slopes of the Vipvska Brda hills at a very attractive southern position with maximum sun exposure. Altitude vary between 300 and 400 meters – some of the highest in the region.
The Pinela, Zelen, Ribolla, Malvasia, Merlot and Barbera are all planted in Guyot at low heights. Yields are particularly low: 1.5kg/vine.
Soil is composed by layers of marl and sandstone, alternating, giving rise to the so-called flysch, locally called Ponca.
The dry climate coupled with exceptional windiness – the Bora winds coming from the Vipacco – favour the ecological approach of Guerila wines. In fact, Guerila Wines are certified Organic“ since 2008 and Biodynamic since 2012. The biodynamic preparations are all produced internally using the local pure sring water.
Fermentations are conducted with indigenous yeasts in stainless steal tanks at ambient temperatures which tend to be cool in Autumn. Spontaneous malolactic fermentation follows. The wines are not clarified nor filtered.
Ageing is usually carried sur lies in stainless steel tanks in the case of white wines and in old French and Slovene oak in the case of reds.
