System developed in the USA by inventor Greg Lambrecht to remove small quantities of wine from a sealed bottle without pulling the cork. This solves the problem of usually having to finish a bottle after opening it, as the wine can then lose its quality in a relatively short time, even after being resealed. The large amount of air or oxygen in the bottle leads to oxidative changes or, in the worst case, spoilage. Coravin is ideal for natural corks or agglomerated corks, but is only partially or poorly suited for plastic corks. With regard to wine types, it should be noted that Coravin is suitable for all still wines, but not for sparkling wines(champagne, sparkling wine). However, these should not be stored after opening anyway, as they become stale relatively quickly.
For my many years of work as an editor with a wine and culinary focus, I always like to inform myself about special questions at Wine lexicon. Spontaneous reading and following links often leads to exciting discoveries in the wide world of wine.
