We'll be completely honest that how long wine lasts after opening depends on several factors. There is simply no one-size-fits-all approach for how your bottle of wine will taste over time once the cork is removed, and this requires a robust discussion to even start covering all the categories.
We can cross off a very important one in that, for us, a still bottle of wine generally lasts about two hours. We've done exhaustive research over many years and can say with absolute certainty that an open bottle of wine in our house does not last more than a few hours.
Sometimes it is as quickly as one hour, sometimes as much as five or six hours, but generally speaking, a bottle disappears within two hours simply because we drink it and never have leftovers.
But all joking aside, we have to admit that is more or less a non-answer. Really, the question we want to address in this one is how long does wine stay fresh after opening, as this topic is far more interesting.
First up, let's touch base on what causes wine to go bad to begin with. As chemical engineers, you know we find this topic fascinating!
