Yoyo KM31 is a natural red wine made from Grey Grenache that incorporates a little Red Grenache and Cariñena. The vineyards of Grey Grenache for Yoyo KM31 are over 100 years old and are located on terraces with slate soils in Banyuls sur Mer. Their yield is very low, only about 8 hectolitres per hectare. Yoyo KM31 is vinified by vatting the grapes without destemming, performing a carbonic maceration for 2 weeks and fermenting with native yeasts. Once fermented, the wine is aged for 7 to 10 months in used French oak barrels that are 4 years old. It is produced without using sulphite during the whole process. Yoyo KM31 is a natural red that is calm, deep and complex. The wine is so called because of the 31km that separated her from her beloved, also a vigneron Jean-François Nicq from Les Foulards Rouges.
