The specially developed hollow needles are the central element of Coravin's wine dispensing technology. Each needle is made of stainless steel and has a non-stick coating. This makes them particularly durable and enables them to pierce the cork easily hundreds of times. However, if replacement is required, replace the old needle with a standard needle identical to the one originally supplied with your Coravin system. The standard needle is compatible with all Coravin wine systems (except the Eleven and Pivot models) and is identified by a black rim at the head of the needle.
