Vinolus x Yaban Sungurlu Pet Nat 2021

Ayağıbüyük Village, Sungurlu, Çorum

Latitude: 40° 5’23.90″N Longitude: 34°29’5.16″E

Ayağibüyük village lies southeast of Sungurlu in the province of Çorum. It is one of the very few remaining areas where the Sungurlu grape is grown, a white variety on the verge of extinction. Thanks to Fettah Kuzurluk, who carefully looked after the old vineyards where this grape grows on clay schist soils at an altitude of 1.025m, and to Selahattin Ambarkütük who helped us reach him.

After the hand-picked Sungurlu bunches were destemmed and crushed, the grapes were put into skin contact in a stainless steel tank for 40 hours in an inert atmosphere.

The juice obtained after pressing was sent into a stainless steel tank for alcoholic fermentation for 30 days under controlled temperatures below 14 degrees. Before the fermentation was completed, with an amount of 24 gr/liter of residual sugar, the wine was chilled down to 7 degrees and coarse filtered to remove inactive yeast and excess cloudiness.

The wine was then was bottled and crown-capped. After bottling, the bottles were kept with stable temperature at 12ºC in the underground cellar during the winter where the yeast have slowly consumed the residual sugars and capturing the bubbles inside the bottle. Spent a further 14 months in the underground cellar before release.
