Specially designed hollow needles are a key component to Coravin's technology. Each needle is stainless steel and Teflon coated, providing durability and easy insertion over hundreds of pours. However, should your needle need to be replaced, the 'Fast Pour' Replacement Needle is thicker than the 'Standard" needle that was initially included with your Coravin System, and as it's name inplies - pours faster!
