A cleanskins wine is a red wine, white wine or sparkling that has no label or information on the winery. 

There are many reasons that a wine might not get labelled, the two most common are; 

• Over production or a surplus of wine on the market reducing the price on the bulk wine market
• Branded wines that were originally sold at a higher price and due to a new vintage were not labelled.

Due to these reasons there is some amazing value to be found in a cleanskin. You could very well be drinking a bottle worth $20 or more.
