Have you ever wanted to taste and see how that single bottle of 1989\u00a0Ch\u00e2teau P\u00e9trus in your cellar is evolving but you really<\/em> don’t want to crack it up just yet?<\/p>\n

Well, the\u00a0Coravin<\/a> Wine Access System might just be the answer to your dilemma.<\/p>\n

\"\"The\u00a0Coravin<\/a>\u00a0is a wine preserving\/dispensing system that allows pouring any amount of wine from a bottle\u00a0without<\/em> removing the capsule and cork. The bottle is returned to the cellar, and then more\u00a0wine can be poured days, weeks, months, and perhaps years later.<\/p>\n

The Coravin<\/a>\u00a0uses a thin, hollow needle pierced through the capsule and cork to “access” the wine. When the pouring lever is activated, the bottle becomes pressurized with\u00a0(inert) argon gas and wine flows through the needle and into the glass. Once wine is poured, the needle is\u00a0pulled out and the cork “reseals” itself. The bottle can then\u00a0be laid away again for pouring later. As argon replaces the headspace in the bottle, the wine suffers no oxidative effects\u00a0as it continues to age.<\/p>\n

Does it really work? At $300 (plus the cost of replacement argon cartridges), I sure hope so. Friends who use it, love it. But being the skeptical one that I am, I still wonder how that bottle of\u00a0P\u00e9trus will fare. And so I’ve decided to test the Coravin<\/a>, but not with the\u00a0P\u00e9trus, but some other wine until I “certify” this latest wine gadget.<\/p>\n

Over the next several months, I will test the Coravin<\/a>\u00a0in several bottles of\u00a0the same wine but sealed under four different closures: a natural cork, a 1+1 (aka twin-disc) stopper, a microagglomerate and a co-extruded “cork.” Wine will be bottled in a control bottle with one closure and a second bottle with the sample closure where samples will be withdrawn with the Coravin<\/a>, and similarly with the other three closure types.<\/p>\n

I will measure pH, total acidity (TA), volatile acidity (VA), free and total SO2, color intensity, hue, total phenols, and most important, dissolved oxygen in wine and headspace oxygen, i.e. the amount of oxygen in the headspace between the wine and closure, and use these measurements to look for any clues for signs of oxidation. Measurements will be taken after one week, one month, 3 months, 6 months and one year.<\/p>\n

This should be interesting. So stay tuned for updates to see if\u00a0the Coravin<\/a> really\u00a0performs.<\/p>\n
