CORAVIN TRAIN WRECK
Just a few weeks ago I reported a 2/3 bottles of Gruaud Larose 85 stored 4y in perfect condition after extracting 1/3 using Coravin. This bottle was left with 1/4 content, but it tasted horrible. The wine has turned chemical, strong rubber. This bottle was heavily extracted on a weekly basis, and was stored only for half a year. What went wrong with Coravin? I think too much extraction caused air to have a mix with the argon gas. After all the pumping of argon gas is not vacuum proof.
