All Coravin wine access needles are stainless steel and Teflon® coated, providing durability and easy insertion over hundreds of pours.. John Wilson, of the Irish Times had this to say recently, "The big question, of course, is does it work? Jancis Robinson and Robert Parker are both fans. Château Margaux uses it to test their wines before sending them abroad for tastings. Recently, I was invited to a follow-up tasting by Coravin agents. We blind-tasted the same resealed wines from February against freshly opened bottles. None of the journalists present were able to tell the difference". free postage
