Crafted by darkness

The entire production process is done in the absolute darkness. The grapes are harvested on moonless nights. The wine is handled in conditions void of light, using night vision goggles. The wine matures in dark cellars, hidden in the caves of Radgona, in the complete absence of light, for up to three years.

That is how we create Untouched By Light sparkling wine.


Inspired by centuries

In the making of Untouched By Light sparkling wine we have relied on the knowledge collected throughout the centuries.

From the period of archduke Johann of Habsburg-Lorraine, who expanded wine production in the Radgona area to the times when the Radgonske gorice cellars were owned by the Swiss-French family Bouvier.

All of it brought us to the unique taste of Untouched By Light.


Science behind

Science behind the wine Emerita professor Ann C. Noble from the University of California in Davis conducted a research about the impact of fluorescent light – commonly used in stores – on the taste of sparkling wines. It was proven that a wine's exposure to light, even for a relatively short period of time, decreases the intensity of citrus aromas and increases the development of its off-flavour, called the light-struck aroma. The perfected sparkling wine production method we devised is directly inspired by these scientific conclusions.
