CSI for your wine cellar? Well, sort of. Wine Spectator reports that Applied DNA Sciences has created a DNA-based system, called SigNature that embeds a customized botanical DNA segment into the ink on a wine bottle cork or a label. The SigNature could not be removed and therefore acts as an encrypted identification system that could help identify bottles belonging to a collector if they are stolen. It could also help verify the authenticity of bottles that are later sold at auction. The service costs about $16 per bottle to prepare and apply a marker for a 5,000- to 10,000-bottle collection, including authentication certificate and scanner but the price drops for producers who want to brand a whole vintage. The SigNature has a variety of applications including the protection of artwork by embedding a DNA signature in a certificate, receipt or sticker.
