Coravin Needles are specially designed to pierce through natural or agglomerated cork and allow you to pour wine without opening the bottle. The thinner design of the Timeless Vintage Needle is ideal for older vintage bottles in your collection. It provides a gentle insertion through potentially fragile corks. All Coravin Timeless Needles are made of stainless steel with a non-stick coating, providing durability and easy insertion for hundreds of pours.
