Describe: Coravin extractor is made of high quality stainless steel, covered with an outer layer of teflon that makes it easy to extract alcohol without affecting the cork. The kit includes 3 needles: Quick needle extractor: a larger needle that makes alcohol extraction 20% faster than the standard needle included with the Coravin machine. Vintage extraction needles: thinner needles, higher elasticity designed specifically for difficult-to-open corks, old and precious wine bottles, to be stored for a long time. Standard extractor: equivalent to the needle available in Coravin machines, suitable for most common wine bottles.
